Saving water in the garden
In hot and dry weather, water used outdoors can amount to 50 per cent of total
usage. In the UK it's possible, however, to have a beautiful and productive garden using very
little mains water. Find out more about what you can do...
Everyday watering tips
Things you can do include:
-
use a watering can instead of a hose
-
if you do use a hose, use a trigger to control the
flow
-
avoid using watering-can roses, except on young seedlings, as much of
the water does not reach the roots where it’s needed
-
watering early in the morning or late at night means water does not
evaporate in the heat of the day before it can reach the roots
-
leave plants and shrubs dry until they show signs of wilting - watering
too often can keep roots shallow and weaken plants
-
weeding regularly makes sure that watering helps plants and not
weeds
-
prioritise young plants and seedlings; more established plants will
survive longer periods without water
Saving water while keeping your lawn healthy
Lawns are usually the thirstiest part of a garden, but there are easy steps you
can take to reduce the amount of water your lawn needs:
-
letting the grass grow longer in dry spells helps keep moisture in the
soil
-
if you use a sprinkler, your water company may require you to have a
meter fitted as they can use as much water in an hour as a family of four uses in a
day
-
infrequent soaks will be more effective than frequent sprinkling as they
will encourage roots to search for water deeper in the ground
-
remember that even if your lawn goes brown in the dry weather it doesn’t
mean it has died - it will usually recover when the rain returns
-
if you’re looking to redo your lawn or re-seed part of it, choose grass
varieties that are better suited to dry conditions like fescue grass or
smooth-stalked meadow
Install a water butt
Thousands litres of rainwater fall on the average roof every year. If you
collect this water and use it on your garden, it is better for your lawn and plants as well
as the environment. Other points to consider:
-
fit a lid to stop leaves collecting or small animals falling in and
drowning
-
if you want to collect more water than can be stored in one butt, it is
possible to get a connector kit to link up two or more
-
water companies and councils often sell water butts at subsidised
prices
Make use of greywater in the garden
Any water that has been used in the home,
except water from toilets, is called greywater. Shower, sink and laundry water can be re-used
in the garden during droughts:
-
greywater from baths and showers can be used to water non-edible
plants
-
make sure it is cool before you use it
-
avoid pouring it straight on to foliage
Plan a water-efficient garden
Things to consider:
-
healthy composted soil will retain moisture and
nutrients
-
choosing drought-tolerant plants means your garden needs less
water
-
planting new shrubs and trees through plastic helps to retain moisture
and control weeds
-
loose mulches (such as wood bark or coarse home compost) around
established plants stop water evaporating
The wider issue
Increasing demand for water means it is important to find ways of conserving
this valuable resource. Saving water in the garden can help lessen the risk of drought orders
and water restrictions, help protect wildlife and reduce climate change
impacts.
Saving water in your home
There is a limited supply of water, and shortages are a problem in parts of the
UK. By saving water, you can help protect wildlife like birds and fish that live in rivers
and wetlands. You can also cut the energy needed for treating water, helping reduce climate
change.
Installing a low-flush or dual-flush toilet
Over half of people in the UK say they are trying to cut down on their water
usage
Toilet flushing accounts for about a third of household water usage. You
probably flush away as much water in a day as you drink in a whole month. There are many
things you can do to cut this down:
-
when buying a new toilet, get a water-saving, low-flush or dual flush
toilet
-
install a water displacement device (sometimes called a 'hippo') in the
cistern of a higher flush toilet - you will reduce the amount of water used for each
flush, typically by one or two litres. Most water companies provide free
displacement devices for their customers
-
fit a variable flushing device to existing higher flush toilets - this
will give you a choice of flush volumes to help save
water
Switch to showers
A quick shower can use much less water than a bath. But power showers can
use more water than a bath in less than five minutes. Think about:
-
fitting a water-efficient shower head to your existing shower. This can
reduce the amount of water you use by a further 30 per cent without compromising
shower performance (these should not be fitted to electric showers, as this can
lead to overheating of the water)
-
avoiding high volume power showers - you can easily use more water than
if you had a bath
Use water-efficient appliances
Half-load cycles use much more than half the energy and water of a full
load
The amount of water consumed by dishwashers and washing machines varies
considerably.
All new dishwashers and washing machines have a European (EU) energy label which
will tell you how much water they user per wash, as well as how energy efficient they are.
Things you might like to consider are:
-
if you have a choice, look for a machine that uses less than 50 litres
per wash
-
try looking for a dishwasher that uses less than 15 litres per
wash
-
make sure your dishwasher or washing machine is fully loaded before you
switch it on - half-load cycles use much more than half the energy and water of a
full load
Upgrade your plumbing
Things to think about are:
-
fixing drips - a dripping tap or overflow can waste a lot of water (just
2 drips a second adds up to about 26 litres of water a day), but a new washer costs
just a few pence and can be fitted in minutes
-
fitting aerator or spray ends to washbasin taps can reduce water
consumption by up to 50 per cent - an aerator mixes air with
water
-
putting lagging on your outside pipes will help to avoid burst pipes and
leaks in winter
Save water in the garden
There are many ways of saving water in the garden:
-
using a watering can rather than a hose will make a huge difference to
the amount of water you use in your garden - a hose can use more water in an hour
than a family of four uses in a day
-
consider buying a water butt to collect rain water for the garden -
using rain water saves mains water and the energy used to treat it
Avoid pouring water straight down the drain
Ways to avoid this:
-
the cold water that comes through before a tap runs hot can be collected
for watering plants
-
keep a jug of water in the fridge instead of waiting for the tap to run
cold
-
turning off the taps when you are brushing your teeth or shaving can
save five litres a minute
