These people are encouraging their neighbours to reduce ground run off (rain) going into the main drainage system from paved areas, making it soak into the ground to replenish ground water AND encouraging everyone to pour used kitchen/bathing water onto the soil in their gardens. The result is the ground water has recovered and the water table has gone UP SIX METRES, (wow),<br />

Water saving devices, greywater recycling and rainwater harvesting not only reduce drinking water demand (which is great news in a drought) but also REDUCE the risk of flooding. Hooray! This is because reducing the flow of water in drains increases the spare capacity in the drainage network for coping with sudden surges in rainfall. <br />
<br />
This is why the BBC is posting slightly crazy articles like: "<a href="http://www.bbc.co.uk/news/uk-england-21179069" target="_blank">Snowmen hold back flood </a>" and why the RSBP are promoting <b>rain gardens</b>. A what? A rain garden is basically a soggy patch in your garden intended to get flooded, full of plants that like a good soaking, sited directly in line with the rainwater downpipe from your roof. This holds water, prolonging the journey time to the drainage network or the nearest river. The more water soaking into the ground, the less water being handled by the drainage network. This is the basic concept behind SUDS or <b>Su</b>stainable <b>D</b>rainage <b>S</b>ystems, which reduce water flow rates from car park areas, by providing a road surface that allows water to soak directly into the ground rather than being collected in surface water drainage pipes which take water to a water treatment works. During a flood, the underground drainage network can get overwhelmed with the volume of water running off roads and roofs, causing raw sewage to pour into nearby rivers and canals. If a river busts its banks... no prizes for guessing where the sewage goes next. So if you are worried about flooding:<br />
<br />
[1] fit water saving devices, like tap flow restrictors<br />
[2] fit a WATERTWO and use your greywater (see <a href="http://wateraware.blogspot.co.uk/2010/11/recycling-your-bath-water-with-water.html" target="_blank">my post</a> on this)<br />
[3] fit a water butt, and use your rainwater (see <a href="http://wateraware.blogspot.co.uk/p/homemade-rainwater-recycling.html" target="_blank">my post</a> on this)<br />
[4] when it snows -BUILD A SNOWMAN !! But more importantly ...by clearing your driveway and creating a pile of snow on the edge of your lawn you are slowing down the melting process.<br />
[6] get all horticultural and plant yourself a <b>rain garden</b><br />
[7] maybe skip that swim in the Manchester Ship Canal<br />

<br />
The above link is a really interesting database, called EWG, that informs you about what chemicals are in your shampoo, shower gel, creams etc etc and provides informative ratings: 10 being BAD and 1 being GOOD. These ratings help to give you an indication of the ecological impact of your toiletries. Basically the more unpronounceable ingredients in your cleaning product means a higher likelihood of harm to plants, regardless of whether this water ends up in your backyard or the nearest river.<br />
<br />
If you want to use greywater recycling, by using laundry or bathwater for watering your garden, remember that natural plant based toiletries or laundry soap will be better for the plants your garden. Washing machines are so fast at spinning, normal laundry may require no washing powder at all! If you think I am joking why don't you try it for yourself?! A warning about crops: do NOT spray plants you are going to eat with greywater but direct water onto the soil so that the soil can act as a natural filter as the water drains down into the ground.<br />

In the Lake District, in Cumbria, North England, there is a campaign called "Love Your Lakes" to encourage people to choose laundry powder that avoids phosphates, as phosphates cause the growth of blue-green algae in lakes like Windermere. Blue-green algae can take over rapidly and destroy habitat for other aquatic plants and animals. Many mainstream laundry powder labels are now getting on board with this and also look out for:<br />

I am starting a new business, developing a water saving device and I am interested to know what conditions are like in other countries outside of the UK. Its hard to get up to date information on water use in other countries so I thought I would write my own quick survey -it only has 10 questions. As so many people read this blog from the USA, India, Canada, Australia and beyond I would REALLY appreciate it if you could share this survey with your friends as it would help me to understand the international marketplace for my invention. </span><span style="background-color: #f1f5f9; color: #333333; font-family: verdana, arial;"></span><br />

<b>Eaga Shower Smart</b><br />
<br />
The Shower Smart is a type of collar that you fit to your shower hose to
restrict the flow of water. It comes in a kit with a plastic bag, which you
use to test your shower before you fit the collar. You fill the bag for 5
seconds via the shower head. After this, you need to look at how much water
you have collected -if its above the high tide marker on the bag then you
should install the Shower Smart.
I tested both the shower over the bath and the power shower in the shower
cubicle at my house. To my surprise, both of these passed the test, with
water in the bag lower that the marker line. The power shower is an aerated
type where air is entrained in the shower head to create additional pressure,
to feel like a power shower without loads more water being used.
The Eaga Shower Smart is only useful to a small number of households as you
have to a high flow shower and it can't be an electric shower, and it HAS to
be fitted between the tap block and the shower hose. Presumably shower smart
can cause faults in electric showers by increasing the resistance in the
shower hose. Eaga claim that the Shower Smart will reduce the shower flow
rate to 7.7 litres/min.<br />

<b>
Littlefoot Water Widget</b><br />
<br />
A rival free product is the Littlefoot Water Widget. Now, I couldn't get
this to work properly water, it just sprayed out of the side hole but I think
this is because my shower is not sufficiently high pressure to try this out.
This is another collar type device that restricts water flow but it is fitted
just behind the shower head. This can be fitted to a wall mounted shower or
a shower with a hose, although not all wall mounted showers will be
adaptable. The Water Widget is also NOT suitable for electric showers and
not suitable for low flow showers (they say low flow means anything less
than... (yep, you guessed it), 7.7 litre/minute)<br />
<br />
I would encourage you to <b>test your shower</b> to see what the flow rate is
currently. I suspect more people have a shower that feels a bit pathetic
than the impressive power shower type. Electric showers are the box on the wall type.
These only have a cold water connection, as the water is heated in the box
and forced through the shower head. This box is usually without an internal
pump so the showering experience can be a bit dissappointing as it relies on
the pressure in the cold water line. This is often the case if you have a
cold water tank in the loft, as its the difference in height between the
shower head and the tank that really matters, the higher the tank the better.
Showers with a mixer tap will be supplied hot and cold water which is
accurately mixed by a thermostatic mixer tap to the correct temperature. This
type of shower is taking water directly from the hot water system that
supplies all the taps. It is this type of shower that the Water Widget is
targeting, and will more likely have a higher flow rate than the electric type.<br />
<br />
<b>Rate Your Shower</b><br />
<br />
You don't need a silly plastic bag to test your shower, just catch the water
in a bucket and time 5 seconds. Pour the water into a measuring jug and note
down the millilitres. Repeat this a few times to see if the answers are the
same. [click on the diagram to zoom in]<a class="pin-it-button" count-layout="horizontal" href="http://pinterest.com/pin/create/button/"><img border="0" src="//assets.pinterest.com/images/PinExt.png" title="Pin It" /></a><br />

<br />
<br />
(millilitres x 12) / 1000 = litres/min<br />
<br />
7-10 litres/min = OK,<br />
<br />
10-14 l/min = too high,<br />
<br />
14-30 l/min = power shower zone, way too high!<br />
<br />
By fitting the Eaga Shower Smart or Littlefoot Water Widget you will be
simply restricting the flow of water, which will mean you use less water per
minute but this may mean you have a dissappointing shower experience.
Personally, I LOVE a good power shower! If you want to save water without
compromising the experience try some of these free products first and if
you're not satisfied try out a aerated shower head like <a href="http://www.ecocamel.com/shop/shower-heads/jetstorm">Ecocamel </a> . If you are
fitting a new bathroom anyway... chose a product like the <a href="http://www.hansgrohe.co.uk/1870.htm">Hansgrohe Raindance Ecosmart</a>.
Hansgrohe claim this reduces the flowrate from 14 l/min to 9 l/min (at 3 bar pressure) without
compromising the power shower experience. Look out for the new Ecosmart
ratings in the UK, now on showers and taps to help you compare water saving products.<br />

Another couple of free things I got given at the supermarket are the <b>"hippo" </b>
and a Littlefoot<b> Flush Bag</b>, these both sit in the WC cistern to reduce the
flush volume. These shouldn't be fitted if you have a new 6/4 litre toilet
as it will probably not give an effective flush, see my <a href="http://wateraware.blogspot.co.uk/p/toilet-flush-water-saver.html">previous post</a> on this . The
Hippo is the better product for older 13 litre cisterns as this displaces
2.5-3.5 litres per flush, whereas the Littlefoot only displaces 1.2 litres.
You don't really need these products to do this, you can just use some old
comestics bottles filled with water to do the same job. Try it!<br />
<br />
All in all these products reduce fresh water consumption but do nothing to embrace the water use hierarchy, (see the <a href="http://wateraware.blogspot.co.uk/2010/09/as-you-can-see-from-my-last-post-there.html">water hierachy diagram</a>) . They are only scratching the surface of the problem, for example: toilets do not need drinking standard water to flush, this is madness!<br />

NB: If you have a disappointing shower with a pathetic drip-drip experience, then my advice is to try descaling the shower head. Do this by taking the shower head to bits (unscrew from the hose, and unscrew anything else if it comes apart) and sitting it in a bucket of Coca-cola overnight. If this descaling didn't work, you need to investigate your water pressure, 3 bar is good and anything less than 1 bar is bad news. 0.3 bar is the minimum recommended for a lot of shower heads/outlets, and this is roughly equivalent of 3 metres of vertical drop between your water tank and the shower head, i.e. electric showers on the ground floor with the cold water tank in the loft are always better than electric showers on the first floor. If you can't achieve this, then the only option is to fit a pump.Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-35145850459295823232012-03-22T16:38:00.005-07:002012-06-21T07:25:30.973-07:00Run your washing machine on rainwater<div class="separator" style="clear: both; text-align: center;">

For World Water Day I am going to explain how to connect your washing machine to a rainwater tank, (see my previous <a href="http://wateraware.blogspot.co.uk/p/homemade-rainwater-recycling.html">post</a> on how to set up a rainwater tank). WHY do this? Answer = because your washing machine needs about 50 litres of water (5 buckets) for every load, this water does need to be clean but it does NOT need to be drinking water standard. Providing rainwater is filtered correctly this is safe to use in your washing machine. In order to connect a washing machine to a rainwater tank, to make use of rain for washing clothes, a few things need to be considered first:<br />
<br />
[1] Your washing machine is expecting water to be available at normal main network water pressure. If the water pressure is too low or the flow of water is too sluggish then the machine may fail to start. This can happen if your tank is too far away or the tank is nearly empty. This normal pressure varies widely, it depends where you live in relation to the network pumping station. In the UK it is commonly 1 to 3.5 bar, although it can be up to 10 bar. In continental Europe, water pressure above 3.5 bar is more common. Now you're thinking -what is 3.5 bar anyway? -this is the same pressure you get from a tap that takes water from a tank 35 m higher than the tap (1 bar = 10 metre head height between the tank level and the tap). So if you have a very hilly site you can get creative to achieve this, but for everyone, else a pump is required.<br />
<br />
[2] The machine is intended to handle mains network water. This is high quality, drinking standard water. However it is perfectly safe for rainwater to be used as a substitute for washing clothes providing that air pollution is not a major problem (acid rain and smog are no longer a problem in the UK) -and- that the collected water is well filtered to remove debris. <br />
<br />
So in order to get water from your rainwater storage tank to the washing machine, you will probably need a pump. (The exception to this is if the tank is higher than the washing machine, e.g. your tank is on the ground floor and your washing machine is in the basement.) I recommend using a power shower booster pump for this purpose as these are already fitted with a pressure sensor.<br />

<br />
<br />
<br />
The pump will automatically switch on when the washing machine starts and automatically switch off when the washing machine stops drawing water. This should provide adequate pressure to ensure the water flow reaches the washing machine. (The more bends and connections and the smaller the pipe diameter and the higher the washing machine, all increase the work load or pressure head demand on the pump). <br />
<br />
These shower pumps (like <a href="http://www.screwfix.com/p/salamander-ct50-contract-shower-pump-with-isolators-1-5bar/46231">this one</a>) are connected to the supply lines normally for both hot and cold connections. You will need to join the two inlets together so that they both accept cold rainwater. The same will need to be done to the two outlet lines, to create one out-going line. <br />

<br />
The rainwater tank should include mesh filters to remove debris and an auto mains refill float valve (see my previous <a href="http://wateraware.blogspot.co.uk/p/homemade-rainwater-recycling.html">post</a> on this). It is also possible to collect the drainage water expelled from the washing machine if you live in a particularly drought prone area (like England! Yes we are in <a href="http://www.bbc.co.uk/news/uk-17340844">drought</a> right now). You can use this to:<br />
<br />
[a] water the garden -make sure you use biodegradable laundry soap! I recommend soda crystals or <a href="http://www.ecozone.com/products/ecoballs_150">ECOballs</a>. Actually you can get away WITHOUT using washing powder at all with a normal load. Modern machines are so good, the spinning action is the main thing that cleans the clothes. This really is the greenest option. Maybe save the laundry powder for just sports kit? Don't water crops directly with the waste water, make sure you direct the water onto the soil only and vary which part of the garden you water. If your plants start to look worse then use the no soap option.<br />
<br />
[b] reuse water from the second wash or rinse cycle to feed back into the first cycle of a second laundry load. This involves manually setting up a bucket to collect drainage water and manually pouring this into the rainwater storage tank for reuse. You will need to time the washing machine to work out how long this takes to finish each cycle, to get the hang of this. <br />
<br />
Most washing machines are designed to pump drainage water back up to worktop height to ensure the drainage water is properlly expelled from the machine, therefore the drain pipeline does not have to be right down at floor level to do its job. Fitting a <a href="http://www.watertwo.co.uk/">WATER TWO</a> drainage valve in the drainage pipeline from the washing machine can be really useful for both of the above tasks, to avoid the need to lift the flexible drainage hose out of the fixed drainage pipe and risk water spilling everywhere whilst you direct it into the bucket. It's OK to arrange the drainage line so that there is enough room to fit a bucket underneath the drainage pipe next to the washing machine with a T junction.<br />

WaterAid is a very worthy charity. They give support to improve sanitation in many areas of the world, including helping victims of the recent <a href="http://www.wateraid.org/international/about_us/newsroom/10349.asp">Cyclone Giovanna</a> in Madagascar. The cyclone has destroyed over 90% of latrines, due to heavy floodwater. WaterAid are working on the ground, trying to improve access to clean water for drinking and safe access to temporary toilets to prevent the spread of water borne diseases.Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-9245248216894464592012-02-21T04:48:00.003-08:002012-02-21T07:01:25.901-08:00Drought Summit<b>We get plenty of rain, so what's the problem? Drought Summit as Rivers in England Dry Up<br />
</b><br />
Yesterday, Caroline Spelman, Environment Secretary , hosted a Drought Summit to discuss the impending water shortage over the next 6 months for the South East, East Anglia and the East Midlands. The meeting involved stakeholders such as farmers, wildlife groups and water companies, to discuss solutions. This is the current situation:<br />

<br />
Ms Spelman, in an interview with BBC Radio 4, was asked "what can we do to save water, get water meters?" she replied "Water meters can be helpful, particularly for households with a small number of occupants or a reduced income. But the most important thing is to save water. Everybody knows how to save water."<br />
<br />
In my opinion this is a short sighted approach from the Environment Secretary. Two-thirds of all water consumption in the UK is from households. Consumers have to be motivated to use less water. Water meters make people realise how much water they are using and also allow people to pay for exactly what they use. This means consumers will be motivated by spending less as well as a moral concern about environmental impact. <br />
<br />
In the same way that counting calories helps overweight people eat less, reading the water meter will give people a better awareness of how much water they use each month in comparison to other households and benchmarks. <br />
<br />
In the UK we have a perception that drought doesn't happen here, it doesn't affect us, as the UK is a cold and wet country. <b>We get plenty of rain, so what's the problem?</b> The real underlying problem is human population. There is a dense, urban population in the UK, particularly in the South East, creating a huge water demand. Looking back at the last 100 years, UK population has increased from 38 million in 1900 to 59 million in 2000, this staggering 55% increase or extra 21 million people, are putting pressure on the water companies to over-abstract water from all fresh water sources. This has already caused long term damage to the environment and wildlife with significant loss of animal and plant species, particularly for wetland and river habitats.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjK51aow5g8eqlXwFR-0I47Baz8feydlFtPGw3XWK6MAZWa_efQJH2k08-kX2OFD4o6eZu_5UWcDT8BVbRI7OQC5Il9-1rhnX_n7slftUaMttv3IKAFBwzN7JaF5spQ0fmJuZ3Lhd3RzVcc/s1600/population.jpg" imageanchor="1" style="margin-left:1em; margin-right:1em"><img border="0" height="300" width="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjK51aow5g8eqlXwFR-0I47Baz8feydlFtPGw3XWK6MAZWa_efQJH2k08-kX2OFD4o6eZu_5UWcDT8BVbRI7OQC5Il9-1rhnX_n7slftUaMttv3IKAFBwzN7JaF5spQ0fmJuZ3Lhd3RzVcc/s400/population.jpg" /></a></div><br />
<br />
From the map below (click on the image to zoom in) you can see how the work of water companies impacts on freshwater resources. There are many areas with no spare capacity (orange to red areas) and many areas are seriously over abstracted (red areas) which harms the local ecology. Almost every inch of the country is being used to collect ground water to serve the public water network.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh987500gqDLehjjAmBxdSaP5OnDWVZfCYCisRD7TI-ctsl_ug2OF6ihr638DFEBfel-BZEE6dbakAMq34xW_cOP8iJHJK88lKhOvDkBbpqg0x1WzSXe5UdHp5lDuCrBALmnKYREHPY6bp3/s1600/Env+agency+UKWATER-fig1.2.jpg" imageanchor="1" style="margin-left:1em; margin-right:1em"><img border="0" height="300" width="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh987500gqDLehjjAmBxdSaP5OnDWVZfCYCisRD7TI-ctsl_ug2OF6ihr638DFEBfel-BZEE6dbakAMq34xW_cOP8iJHJK88lKhOvDkBbpqg0x1WzSXe5UdHp5lDuCrBALmnKYREHPY6bp3/s400/Env+agency+UKWATER-fig1.2.jpg" /></a></div><br />

Unfortunately UK consumers are in a weak position to react to this drought warning for the following reasons:<br />
<br />
- fixed tariffs, often set annual, no penalty for high water use<br />
- water meters are not mandatory, most people have no idea how much water they use<br />
- few water saving products available that offer real savings<br />
- prohibitively high cost of installing rainwater recovery systems<br />
<br />
I see the only way to curb this demand in the short term is to motivate households to save water e.g. by making water meters mandatory, promoting the use of water butts for gardening, higher tariffs for excessive water use. There are many ways to reduce water consumption but most people are not motivated to do this currently as the perceived consequences of carrying on as normal are nil. In the long term the government will need to reduce UK population to a sustainable level that puts less strain on the available water resources.Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-73026824827214670882012-02-09T02:11:00.000-08:002012-02-09T06:23:38.304-08:00WaterAid update.<br />

As it's World Water Day, following on from my <a href="http://wateraware.blogspot.com/2011/03/collecting-rainwater.html">last post about collecting rainwater </a>... this post is all about fitting a homemade rainwater harvesting system. I recommend using a blue barrel with a clamp on lid as a storage tank as the clamp will come in handy to fit the water filters. (but you can use any tank you like, appropriate to the level of rainfall you are expecting to store). Note that storing water for a long time may give you problems due to the attraction of bugs and bacteria (particularly for hotter countries). You may wish to dose your water with chemicals to avoid this. See the following image, click and zoom for details. <br />

Note that I say "adapted" fresh water inlet valve, this means you will have to adjust the float arm length or position until you are happy that it refills with normal water to the right minimum level. Something like <a href="http://www.screwfix.com/prods/90110/Plumbing/Toilet-Fittings/Pegler-Float-Valve-Part-1">THIS </a>plus a ball float valve. You may have to extend the arm, use a brass or plastic rod for this, something that won't rust or decay underwater. <br />

To collect rainwater from the roof, note that the water will swirl around on the inner surface of the rainwater down pipe from the roof. Therefore for capturing this, an inner edge that encourages water towards the opening mouth of your feeder tube (towards the storage tank) can increase the efficiency of collection. Also it is a good idea to have an overflow pipe flowing down at an angle from near the top of the storage tank, back to the rainwater down pipe. This stops excess water going over the top<br />

Water draining away from the washing machine could be collected for reuse -but I'll save that for a separate post.<a href="http://wateraware.blogspot.co.uk/2012/03/run-your-washing-machine-on-rainwater.html">....now available - click here</a>Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-88452001174208142582011-03-18T12:03:00.001-07:002012-04-03T13:35:14.468-07:00Collecting rainwaterIf you want to collect rainwater and start using it, you should first consider how big the tank should be. This depends on how much you can collect and how much you need. Rainwater is absolutely safe to use for watering your garden and washing your car, and if filtered correctly it can be used to run your washing machine. (See my other articles on <a href="http://wateraware.blogspot.co.uk/p/homemade-rainwater-recycling.html">how to make a rainwater harvesting system</a> and <a href="http://wateraware.blogspot.co.uk/2012_03_01_archive.html">how to connect this to your washing mashine</a>)<br />
<br />
HOW MUCH CAN YOU COLLECT?<br />
<br />
To work out how much you can collect, you have to think about how often it rains and how much rain arrives. I live in Manchester, UK, where it's fair to say it rains every 3 days, or we have that kind of reputation anyway! If you live somewhere hot and dry you may have problems with infrequent rain, which, when it does arrive there is so much you hate it and then, all of a sudden, it's gone again and you are back to hot and dry weather. Anyway, you know about where you live so you know best. However, you can look up the rainfall from a local weather station which will give rainfall typically data is millimetres of rain, collected monthly. Now millimetres means just that, the depth of the rainfall, rain falls every where equally so if you have a small cup or a large bucket, you will collect the same number of millimetres, depth of water. The volume of water you collect depends on the AREA of the cup, or the bucket, or the pond or the roof etc. etc. Normally, you can easily get your hands on mean i.e. typical monthly rainfall in millimetres. Try websites like <a href="http://www.wunderground.com"> WUNDERGROUND </a> for this. The following graph is for Edinburgh, Scotland -which like Manchester, England, gets frequent rainfall throughout the year. (Click and zoom for a closer look...)<br />

<br />
HOW BIG IS YOUR ROOF?<br />
<br />
The best way to collect rainwater from a large area is to use the roof of your house. It doesn't matter whether it's a pitched roof with an apex or a flat roof, the pitched roof will not collect anymore water than the flat roof, providing you have a gutter or drainage channel to retrieve the water, and your roof is relatively clean, then, you're in business. If you know the width and length of the roof in metres you can work out how much water you can collect in a month, in the following way:<br />
<br />
mm rainfall divided by 1000<br />
<br />
x width (metres) x length (metres)<br />
<br />
and divide the total by 1000, this is how many litres of water you can collect in a month.<br />
<br />
Water Demand = number of litres a month you will use up.<br />
<br />
Providing rainwater is filtered, it can be used for laundry. Laundry - 65 litres per load is a good guess for a front loading European style machine.<br />
<br />
Rainwater can be used to flush the toilet, this requires some plumbing work to pump the water to the cistern -it will not fill if the supply has no pressure. Water use for toilet flushing -a good guess is 5 flushes per person per day living at home. What type of cistern have you got? 6 litres, 9 litres, 13 litres? see this <a href="http://wateraware.blogspot.com/2010/10/start-saving-water-today-for-bad.html">POST</a> for help<br />
<br />
Calculate: cistern size (litres) x no.of people x 5 flushes per day.<br />
<br />
Gardening - this could be anything, depends on your passion for gardening!<br />
<br />
Add up all you figures for demand from gardening/laundry/toilets.<br />
<br />
Compare your demand figure to your litres of rainfall. Ideally you want these figures to be equal, to collect as much as you want to use. If the rainfall is higher then this is not a problem, but if the demand is more then you could try increasing the size of the tank, or looking for another roof to take water from, or reduce your demand somehow. Also remember that water demand for gardening will be seasonal.<br />
<br />
To get the right size tank you have to consider another factor -frequency of rainfall, this just goes on your judgement and any detailed rainfall data you can get your hands on of course! In the UK, as it rains so frequently, a 14 day storage is advisable, so that if an enormous deluge of rain occurred and then it was dry for the next 2 weeks you would be able to "ride the wave" between supply and demand. How do you check this -calculate:<br />
<br />
14 x daily demand for gardening/laundry/toilet flushing = tank size<br />
<br />
Now if you live in Australia, for example, you may find a much, much larger store (storage for 8 weeks or more) is necessary to make your project worthwhile.<br />

Treating water to this high standard takes a lot of energy to pump water from A to B, the waste water treatment and for the cleaning of fresh water taken from rivers and reservoirs. It has been estimated that for each 1000 litres of water arriving at your tap this requires 2.2 kWh of electricity to treat. If your water comes from a desalination plant which convert salty sea water into fresh water this requires a further 1.5 to 2.5 kWh to process, depending on how efficiency the plant is. <br />
<br />
And shock horror! News just in .... according to the <a href="http://www.guardian.co.uk/environment/2011/jan/13/london-super-sewer">Guardian</a> 39 million tonnes of "sewage" goes into the river Thames, in London, every year! Now that's gross! The fact remains is that many EU countries pay fines rather than fixing the problem of pumping sewage into rivers or the sea. Most rivers in the UK are over abstracted -i.e. the water companies are regularly taking too much water out of the river and this harms the river ecology.<br />
<br />
Any greywater you can divert directly onto your garden, rather than down the drain, cuts out this long cycle of man made treatment and delivery. Water that goes into the ground will be filtered naturally and eventually end up in the sea and evapourate and return as RAIN. Likewise any water you can collect as rain also interrupts this cycle. In areas where acid rain is not a problem and air pollution is closely regulated, rain can be a relatively clean source. Obviously, you must be careful what kind of water you use like this -see my diagram of the <a href="http://wateraware.blogspot.com/p/household-water-use.html"> WATER USE HIERARCHY</a><br />

<br />
It's important to use biodegradable soap & cleaning products when you are <a href="http://wateraware.blogspot.com/2010/11/recycling-your-bath-water-with-water.html">re-using your bathwater</a> to water the garden, as normal soap takes a long time to break down from complex chemicals into more useful simple substances that plant life can absorb. So I thought I would write something on biodegrable soap...first of all, look out for vegetable based solid soap like Marseille soap or glycerin soap. Glycerin soap is usually translucent. Marseille soap uses olive oil as a base. <br />
<br />
<br />
<br />
If you prefer to use liquid soap or shower gel, rather than solid soap, you can make your own shower gel by:<br />
<br />
[1] grating solid soap into flakes <br />
<br />
[2] putting these into an old shower gel bottle with some hot water<br />
<br />
[3] Shake the bottle for a few minutes and leave it to stand for a day or too. <br />
<br />

<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
This is then ready to use. This is also good for the environment because it stops you buying shower gel bottles which then have to be recycled or just thrown away, ending up in landfill. If you can't be bothered with that, you could use solid soap in the shower, if you have somewhere to put it... you can put in on a string and hang it up above the bath. The best way to do this is to use a screwdriver to grind a hole by hand through the centre of the bar of soap and thread some thick cord through this. Its best to hang the soap high up so its not in the water stream, this way it will last longer.<br />
<br />
CHOOSING CLEANING PRODUCTS<br />
<br />
As for biodegradeable cleaning products to clean your bath, try using soda crystals or borax. You can buy these sorts of products in cardboard boxes (again less plastic waste) from Clean and Natural by <a href="http://www.dripak.co.uk/">DRI PAK</a>. If you scrub this powder onto the surface of the bath with a bit of water and leave it for a while before washing it off again, it is pretty effortless -on a par with stronger household cleaning products but with less ecological impact. These products are easy and safe to use and odourless. Soda crystals are produced by a relatively simple chemical process which means its more easily broken down, unlike phosphates which are found in more modern cleaning products. for more information on this subject see this page on <a href="http://www.sas.org.uk/campaigns/toxics-2/">toxic water</a> by Surfers Against Sewage (SAS)Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-21141371937442214292010-11-12T01:10:00.001-08:002012-11-07T03:49:20.811-08:00RECYCLING YOUR BATH WATER WITH WATER TWOHello again!<br />
<br />
I wanted to talk about the WATER TWO and dispell a few myths about drainage and what happens when water goes down the plug hole. All water from the kitchen sink, the bath, a wash hand basin, the shower, goes down a pipe into the sewer. All drainage or waste pipes should have a U bend where water collects, to stop bad smells rising up the tube and filling the house, but beyond the U bend or "trap" the tube will be empty, most of the time. If you were able to look inside a drainage tube around your house, it would probably be empty -it is not full of dirty water all the time like the sewer underground -it is usually empty until someone.... lets the plug out the bath, or the sink, or runs the washing machine. <br />
<br />
If you go to a hardware store you can buy straight lengths of drainage tube and bends but not valves as normally there is no need to have a valve.... however, if you are keen to save water a valve is very useful to divert greywater to recycle it for other uses like watering your plants. <br />

A company in the UK sells drainage water valves called <a href="http://www.watertwo.co.uk/">WATER TWO</a> -this neat device lets you divert water from your bath for use in the garden. You attach it to the down pipe directly from the bath -this relatively clean water can be recycled to be used in the garden. When you take a bath leave the plug in. Go outside turn the WATER TWO valve to divert, then pull the plug out the bath and open the spray on your garden hose to start watering all those thirsty flowers.<br />
<br />
This is one of the pathways identified in my previous post on the <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEggtqza2E919erMZ69yA6fXjcMVIk5JxCfoNjNSjilKqnKCzmmnTioyKgkcL4h_qtjAn8gpFDfWu6Ynsl_VeXFXOSgFb3PepVnkeaqm8y2fhpdvXFDqMXnbXc_VnR8E4bKmY59U7rirCgtP/s1600/water+hierachy.bmp">water use hierarchy</a>. This is a great way to water your garden at no extra cost and you can fit it without getting wet! This also lengthens the pathway of the water between water treatment cycles as water will naturally be filtered by the plants before ending up in the atmosphere or travelling to the nearest river or water course. This means by the time the water reaches a water treatment plant (via a river or lake) to be converted into drinking water, it is already quite clean.<br />
<br />
A bath uses up to 80 litres of water and if you have a shower over the bath, using shower to collect water, this might collect 40 litres of water. Bathing uses roughly 30% of all household water and provides a regular and reliable source of water for your garden, unlike rain!<br />

If you are keen to start using a WATER TWO diverting valve then you must use it responsibly, remember that bathwater is not as clean as water direct from the tap:<br />
<br />
<b>Don't store this water</b> in a barrel. Over time, e.g 1 or 2 days or more, microorganisms like bacteria will multiply and you want to avoid this as you will come into contact with this bacteria as you water your garden.<br />
<br />
Don't spray plants directly, <b>water the soil.</b><br /><br />
Don't water plants that you are going to <b>eat</b>, e.g. lettuces.<br /><br />
Do use <b>environmentally friendly soap</b>. Products with low salt (Sodium Chloride), Boron and Phosphates are better. Avoid using bathwater that contains bleach or other household cleaning products, these chemicals will not be good for your garden.<br /><br />
Don't use the WATER TWO system if someone in your household has an infectious disease or diarrhoea, because watering your garden could<b> increase the risk of other people becoming ill</b>.<br />
<br />Greywater tends to be a bit <b>alkaline</b>, so flowers like Azaleas which prefer acid conditions don't grow well with this type of watering. Clay soils have low permeability so can't absorb water easily and may not cope with absorbing the salt found in greywater. Keep an eye on your plants, if they look weakened by greywater, alternate use with normal watering from the tap and water different parts of your garden to spread out the exposure to greywater.<br />

Once you have watered your garden, remember to wash your hands before you eat!Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-47863844089692436732010-10-20T13:20:00.000-07:002011-01-22T07:52:38.673-08:00Toilet flushing water saver<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEidadneNvbEUEgJ5UBEpOYE37reULs_BYMGH50WGnT3adduTSHtWLOk9qoRmBRvROYBCM7Ds4gIWW12vWRnsqqbaq_-FqzrFxpcL6_zSwJEbjlAzEg0cFg4sU9zXNrFqYdiTUeTsWagju_n/s1600/homemade+hippo.jpg"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 315px; height: 400px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEidadneNvbEUEgJ5UBEpOYE37reULs_BYMGH50WGnT3adduTSHtWLOk9qoRmBRvROYBCM7Ds4gIWW12vWRnsqqbaq_-FqzrFxpcL6_zSwJEbjlAzEg0cFg4sU9zXNrFqYdiTUeTsWagju_n/s400/homemade+hippo.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5530227124202791666" /></a>Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-47543818337914836432010-10-15T10:09:00.001-07:002010-10-15T12:07:48.166-07:00START SAVING WATER TODAY FOR B.A.Das part of BLOG ACTION DAY [blogactionday.change.org] -or- BAD ! I will be showing you how to make some simple steps towards using less water around your home. <br /><br />How to use less water to flush the toilet - a quick resolution you can start using today....<br /><br /><br />If you have an old 13, 11, 9 or 7.5 litre WC consider fitting a water dispacement device inside your toilet cistern to reduce the volume of water flushed down the toilet every time you flush. 6 litre toilets were being fitted from 2001 in the UK to comply with new water regulations -this advice is not for a 6 litre or less system -its for older installations only! Some people might recommend using a hippo to do this - in my opinion this is not necessary, just get a plastic milk bottle -wash this out and fill it with fresh water, leave the top off and place it inside your cistern. You might need to try a 1 litre bottle instead, see what fits best. If its tricky to see what fits then turn off the water at the mains and flush the toilet to drain out the cistern, then take the lid off and see if one or two 1 litre bottles can be sat inside the cistern....<br /><br /><br />Remember any toilet needs 4 to 6 litres to perform a powerful flush. If you are not sure how big your cistern is 9 litres, 13 litres, 6 litres etc then measure the width depth and height of the cistern in centimetres and do the following sum:<br /><br />width x depth (front to back) x height of the water in the tank<br /><br />then divide the answer by 1000<br /><br />this is the number of litres (generous estimate) that your cistern holds. The more bottles you get in the more water you save but don't over do it.... <br /><br />How much water will you save? well... it depends ....toilet flushing is probably about 30% of your water bill so if you cut it by 3 litres, say improving from a 9 litre flush to a 6 litre flush you have just saved about 10% of your water bill....<br /><br />happy plumbing! .... and remember that's precious drinking standard water you are flushing down your toilet and even though you might find messing about with your cistern a bit gross -you are lucky! yes lucky! -some people in the world don't have a toilet at all which leads to a much more messy, stinky and altogether unsanitary existence!<br /><br /><br /><div id="change_BottomBar"><span id="change_Powered">Change.org</span><a>|</a><span id="change_Start">Start <a href="http://www.change.org/petition" target="_blank">Petition</a></span></div><script type="text/javascript" src="http://www.change.org/widgets/content/petition_scroller_js?width=200&causes=all&color=00B1FF&partner=1654-164"></script>Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-17060427129777963932010-10-13T14:50:00.000-07:002011-01-21T09:36:54.827-08:00Reading your meter<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjqaHEtZsR-_I8vJX4WTS-SYBSA2WJGSUY9sK0ZgyMCwOmaBqp0Di4uEvTd1e8RxX5cw5-wgDbbwJ7wMnatm7PqW5ZvBemE365gjFajwpAzqHCW9oC5bLeI3-1ljTThgFSbM5ot3dyuJ_-2/s1600/water-meter-342896843.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 400px; height: 276px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjqaHEtZsR-_I8vJX4WTS-SYBSA2WJGSUY9sK0ZgyMCwOmaBqp0Di4uEvTd1e8RxX5cw5-wgDbbwJ7wMnatm7PqW5ZvBemE365gjFajwpAzqHCW9oC5bLeI3-1ljTThgFSbM5ot3dyuJ_-2/s400/water-meter-342896843.jpg" alt="" id="BLOGGER_PHOTO_ID_5527651436078995586" border="0" /></a><br />
water meter. So... as I was saying before -if you do have a water meter it will (probably) read in cubic metres - this one shows 1285.4058 cubic metres. The red figures are after the decimal point.Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-26575434073025848132010-10-13T14:19:00.000-07:002010-11-14T12:18:04.868-08:00BLOG ACTION DAYFor Blog Action Day 2010 I 'll be writing about how to save water on the 15th Oct but just for now I wanted to say the first step to saving water is actually getting a meter because having a meter shows you just how much water you are using. Saving water is just like going on a diet -like counting calories -you have to know where you're at........to know where you are going to get to. Knowing exactly how much water you used last month really helps you to work out -am I doing OK? Could I be doing more? The average person in the UK uses about 150 litres of water every day or 0.150 cubic metres (which is what your meter will read in). So, in a month, you should use about 4.5 cubic metres per person in your house. The best new housing in the UK under something called "The Code for Sustainable Homes, Level 5 or 6", requires new houses to achieve 2.4 cubic metres per person per month. -How are YOU doing?Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-49478124627519247712010-10-13T13:55:00.001-07:002010-11-14T12:17:48.312-08:00climate change research papersee my research paper on climate change and air conditioning at:<br /><br /><a href="http://bse.sagepub.com/content/31/1/75">Climate Change in Housing</a>Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.comtag:blogger.com,1999:blog-5901198843351373741.post-21796715159446351372010-09-17T00:42:00.002-07:002012-04-03T14:04:06.952-07:00Water Use HierarchyAs you can see from my diagram, there is a HUGE opportunity to use less water in our daily lives with the right equipment to hand. Currently we use drinking quality water -cleaned to a very high standard for everything -even flushing the toilet -which is total madness when you think about it!

We use a lot of water but we need to be aware of what the worst things to do are...like watering the garden with a hose and leaving the tap running whilst you brush your teeth...<br />
<br />
How much water do we use?<br />
<br />
80 litres = a full bath<br />
<br />
50-65 litres = one load of laundry in the washing machine<br />
<br />
25 litres = one load of the dishwasher<br />
<br />
70 litre = power shower (typical use)<br />
<br />
6 litres = (IF) you leave the tap running when you brush your teeth<br />
<br />
35 litres = normal pressure shower (typical use)<br />
<br />
30-40 litres = to wash the car with a bucket<br />
<br />
6 to 13 litres = to flush the toilet (depends how old your cistern is)<br />
<br />
400-500 litres = watering the garden with a hosepipe<br />

According to USwitch.com using a washing machine for one load uses approximately 65 litres of water. Considering per person we use typically 150 litres per person per day this is quite a lot of water. When I was living by myself I would running the machine once a week, so recycling 65 litres, i.e collecting water from the washing machine and pouring on the garden or using it to flush the toilet etc would save roughly 6% of my water in a week, and what a workout! This is equal to about ten flushes a week saved.Lisa Collinshttp://www.blogger.com/profile/00837099712579010646noreply@blogger.com
