Water Conservation
In England and Wales, as in many parts of the world, the balance
between water supply and water demand is becoming a more and more
vital issue. During the past two decades we have been steadily increasing
the amount of water we use in the home, and forecasts indicate that
this upward trend will continue.
If we do not carefully manage our natural resources and the demands
made on them, then the water environment will suffer and the security
of water supply could be in jeopardy.
Top tips for saving water in the home
By thinking carefully about your water use in the home
and changing some water-wasting habits, it is easy to save water.
- Vegetables and fruit should be washed in a bowl
rather than under a running tap and the leftover water can be
used for watering house plants.
- Use the minimum amount of water required when you
boil water in saucepans and kettles; that way, you’ll save
energy as well as water.
- Try keeping a bottle or jug of water in the fridge
instead of running taps until the water runs cold.
- Half-load programmes on dishwashers and washing
machines use more than half the water and energy of a full load.
Therefore, wait until you have a full load before switching the
machine on.
- Try not to leave the tap running while you brush
your teeth, shave or wash your hands, as this can waste up to
5 litres of water per minute.
- A 5-minute shower uses about a third of the water
of a bath. But remember that power showers can use more water
than a bath in less than 5 minutes.
- Old toilet cisterns can use as much as 9 litres
of clean water every flush. Reduce this by placing a ‘save-a-flush’
or ‘hippo’ in the cistern.
- Cotton wool and tissues should be put in a waste
bin rather than flushed down the toilet.
- Dripping taps can waste up to 4 litres of water
a day. Replace worn tap washers for a quick and cheap way of saving
water.
- Burst water pipes can cause serious damage as well
as waste water. Ensure your water pipes and external taps are
lagged in time for the cold winter months.
Top tips for saving water in the garden
In England and Wales it is possible to have a beautiful
garden without using any mains water. The following top tips will
help you to stop wasting water in the garden:
- Watering in the cool of the early morning or evening
helps to reduce evaporation losses.
- If plants and shrubs are watered too often they
will remain shallow rooted, weakening the plant. Leave them alone
until they show signs of wilting.
- You can use a watering can to water plants with
rainwater collected in water-butts. If you prefer to use a hosepipe,
fit a trigger nozzle to control the flow.
- Careful weeding and hoeing ensures that watering
helps plants and not weeds.
- Plant flowers and shrubs that thrive in hot and
dry conditions such as thyme, evening primrose, rock rose,
- Californian poppy, pinks, lavender, buddleia and
hebes.
- Mulches such as wood chips, bark and gravel help
to prevent water evaporation and also suppress weed growth, saving
you both water and time spent weeding.
- Lawns can survive long periods of dry weather if
the grass is not cut too short. Even if the grass turns brown,
it will quickly recover after a few days of rain.
- Decking, gravel, paving and cobbles can make an
attractive alternative to water-thirsty lawns and have the extra
benefit of being low maintenance.
- Garden sprinklers can use as much water in an hour
as a family of four uses in a day. If you use a sprinkler, many
water companies require you to have a water meter fitted.
- Washing your car with a bucket and sponge uses
much less water than using a hosepipe.
If you prefer to use a car wash, find one that recycles the water.
What not to flush down the toilet
What you flush down your toilet could pollute streams and rivers
or end up on a beach. Here are some tips on what not to flush. Taken
fron the Bag it, Bin it, don't flush it campaign
Disposing of personal Items in the home:
Sanitary Towels and Tampons - wrap well and dispose of
along with other domestic waste. Special bags for sanitary protection
items are available from pharmacies.
Disposable Nappies - as with sanitary towels
wrap well and dispose of with other domestic waste. Before you do,
you could flush any solids - but not the actual nappy - down the
toilet. See also nappy section below.
Razor Blades - put the used blade inside
a rigid container which you are also throwing into the dustbin.
Razor blades should never be flushed down the toilet.
Condoms, Incontinence Pads and Bandages -
dispose of in the same manner as sanitary towels.
Medicines - any unwanted or unused medicines
should be returned to your local pharmacy for safe disposal. Do
not dispose of medicines with other household waste. Always remember
to keep all medicines out of the reach of children.
Syringes and Needles - your local hospital
or health authority will be able to advise you on the availability
of local ‘needle banks’.
Spread the Message to Others
Talking to your friends and family about the campaign is a great
way to spread the message. Many people flush things down the toilet
because they are unaware of the damage it can cause, not because
they don’t care.
Nappies
Disposable nappies are often flushed down the toilet and end up
in our sewers and on our beaches. Aviod the problem by using reusable,
washible nappies.
Real Nappies Association
Promote the use of reusable (washable, non-disposable) nappies for
mothers, local authorities and health workers.

Dos and Don'ts of waste water
(Courtesy of CAT http://www.cat.org.uk/catpubs/tipsheet.tmpl?sku=06)
You can cut down on the total amount of water you
use by reusing waste water, but beware, waste water can only be
used for certain things.
1. Scale your waste water re-using efforts to suit
your garden water requirement; collect and use only as much greywater
as is required for reasonable irrigation.
A good, conservative rule is that a square foot of loamy garden
soil, rich in organic matter, is capable of handling one-quarter
gallon of waste water per week. If the garden area suitable for
greywater irrigation is 400 square feet, then up to 100 gallons
of water may be used in the garden each week. This rate may be greater
in the summer months when surface evaporation and plant transpiration
is considerable, and should be less during the winter when there
is rainfall.
Garden water conservation measures should also be employed. Using
mulches of compost, planting in depressions, and landscaping with
plants native to your area will reduce your garden's need for water.
Frequently check soil moisture to determine precisely when the garden
is in need of irrigation.
2. Water in, water out. Never store greywater, not
even for a day. The drums you see in properly designed greywater
systems are called 'surge' or 'buffer' tanks. Their purpose is to
accumulate greywater as several or more sources are generating it
at the same time, and to hold it temporarily until a hose or pump
can distribute it to the plants. Storing greywater on warm or hot
summer days can quickly produce a septic bacterial soup, which is
likely to stink and to breed disease pathogens. Waste water in excess
of what is needed should be discharged into the sewer in the conventional
manner.
3. The order of preferential use for types of greywater
is as follows: shower and bath; bathroom sink; utility sink and
washing machine; kitchen sink and dish washer.
4. Never apply greywater with a sprinkler or onto
a lawn. Greywater should never 'daylight' pool, puddle, or lie on
the surface of the landscape. Following this advice prevents insects
from breeding in puddled greywater, animals from drinking it, and
kids from being attracted to splash in it.
5. Distribute the greywater to different sections
of the landscape every couple of days, depending upon your yard's
soil structure. Never apply greywater exclusively and continuously
to the same spot, or the soil will be destroyed. A set of simple
manual valves in the landscape will allow you to rotate the greywater
to a different section every couple of days, depending upon how
much of it your household generates. That way plants only get greywatered
every week or two.
6. Avoid using greywater on acid-loving plants, because
the water will be slightly alkaline, due to soaps and detergents.
Most shade-loving plants prefer an acid soil; examples include:
blueberries ( Vaocinium spp.), heath (Erica spp.), heather (Calluna
spp.), spruce trees (Picea spp.), pin oak (Quercus palustris), crepe-myrtle
(Lagerstroemia indica), lily-of-the-valley (Convallaria majalis),
holly (Ilex spp.), mountain ash (Sorbus spp.) and hemlock (Tsuga
spp.).
7. Be cautious about which soaps, detergents, and
cleansers you use in the laundry and bathroom. Use only those products
which are considered safe and non-toxic for people. (A good reference
book is Non-toxic & Natural, by Debra Lynn Dadd.) Avoid products
with boron, such as Borateam and Boraxo. Limit your use of bleach
as much as possible, or, even better, cut out bleaches altogether.
If you have hard water, add 1/8- to 1/4-cup hexametaphosphate per
five gallons of laundry water in place of bleach, and then use one-half
the amount of your normal detergent. For kitchen and bathroom cleaning,
use simple scouring powders such as Bon Ami rM Cleaning Powder.
8. Over extended periods of greywater application,
sodium levels may build up in the soil resulting in poor soil drainage
and potential damage to plants. High levels of sodium may be detected
by conducting a pH test of the soil using pH paper (commonly available
from pharmacies or nurseries). A pH of 7.5 or above indicates that
your soil has become overloaded with sodium. You can correct this
problem by spreading gypsum (calcium sulfate) over the soil at a
rate of 2 pounds per 100 square feet per month. Continue treatment
until the pH of the soil drops to 7.0 As a precaution against further
sodium build-up, gypsum may be applied to the soil receiving greywater
at a rate of 1 pound per month for every 20 gallons per day discharge.
(This means that if you are discharging waste water to the garden
at a rate of 50 gallons per day then a monthly application of 21/2
pounds of gypsum is required to neutralise the detrimental effect
of the sodium). Normal dilution of waste water by rainfall or fresh
water irrigation also will help leach the soil of sodium and excess
salts.
9. Unless you are opting for the simplest methods
of collecting your waste water, i.e. with buckets or a siphoning
system, you will need a surge tank. It must have an overflow port
into the main sewage line, in case the system can't distribute the
water fast enough during peak loading. If possible, this overflow
line should rely upon gravity flow and connect to the blackwater
(sewage) line with a minimum 1/4-inch drop for every 10 feet of
run. Add a one-way swing check-valve between the sewer line and
the surge tank to allow greywater to drain into the sewer, and to
prevent a stopped-up sewer, God forbid, from filling the surge tank.
(It's important that the valve be installed with the embossed arrow
pointing downstream toward the sewer or septic tank.)
10. If you are plumbing in a greywater system you
will need a set of two ball-valves or a single three-way valve.
This allows for convenient switching back to the sewer or septic
tank when necessary; for example, whenever it rains too hard for
the greywater to seep into the soil, or during the winter in cold
climates, or if someone becomes ill with a dangerous communicable
disease. The switching can be done with a remote-controlled electric
solenoid three-way valve. One flip of the switch and the water is
diverted to either the greywater system or the sewer.
