harvesting rain water
Rainwater tanks are a great water saver that helps
reduce your water bill. Using rain water
tanks, which store rainwater run off from your roof to use on your garden, is
rewarded by some councils with a cash back rebate. Contact your local Council to see if you are
eligible for a rebate.
The size and type of tank is determined by the size of
your property. Tanks now come in all shapes and sizes and can even fit under
your house or act as a fence. Rain water
tanks need regular and ongoing maintenance and should have some filtration to
separate out any leaves, animal droppings and heavy metals from traffic.
Ensure the amount of water you capture makes your
choice worthwhile for the environment and your hip pocket.
grey water re-use
Reusing water from your shower, bath, hand basin and
laundry is a practical and sustainable way of watering the garden.
Grey water can foster harmful pathogens and bacteria
if left untreated but there are filters on the market to alleviate health
concerns. Regulations vary and you
should check with your local Council, but most places allow untreated, diverted
grey water connected to a sub surface irrigation system for garden
irrigation. Grey water should be tested
to identify any potential problems before use on your garden.
Areas that have heavy clay soils and an inability to
provide an alternative disposal option in the case of system failure should not
utilise a grey water system.
Use a phosphate and petrochemical free,
biodegradable laundry powder, soaps and shampoo to safely reuse the water on
the garden.
Grey water systems are fairly inexpensive and are
available from plumbers or as DIY kits. The
simplest systems involve a pipe from your shower, bath, hand basin and washing
machine to a slotted pipe that is buried underneath the garden soil. Others
systems store water for use when required.
A system imitating ‘creek beds’ under or on the surface is another very
effective means of harvesting water.
Treated grey water systems remove contaminants from the water and allow
greater flexibility in how water is used.

systems
- If a sprinkler system is in use, make sure
the water is landing on the garden and not the footpath, road, or your paved
areas
- Conventional
sprinklers deliver large amounts of water to large areas and can be very
wasteful if not carefully positioned
- Computerised
watering systems deliver a set amount of water at specified times, to specific
parts of the garden. Tap timers are a
useful and cheap alternative
- Consider replacing inefficient sprinkler
systems with drip irrigation. The main advantage is that it sends water to the
roots of your plants. Inline drippers,
weeping hoses and drip tubes are designed for placing under mulch. These are
low pressure watering systems which, over a period of several hours, deliver
water directly to plant roots. Inline drippers are also suitable for lawns
- Check your sprinklers and timers regularly
and make sure they’re working efficiently
- If you’re not using an automatic timer for
a sprinkler, use an alarm clock to remind yourself to turn it off
- Use an adjustable water-efficient hose
nozzle, that ranges from a high-pressure jet to a mist spray. A trigger nozzle allows the water flow to be
totally shut off. Turn the tap off when
you’ve finished to avoid leaks
- Check your hose, connectors and nozzles
regularly for leaks
- Use a broom rather than a hose to remove
leaves or dirt from hardscaping such as footpaths and driveways
