About Being Water Wise
Recent studies show that if the growth in population, residential development and
commercial development continues at its present rate, Southern Africa's already
limited water resources could be fully exhuasted within the next 20 to 30 years.
Globally, in the not to distant future, it is likely that wars will not longer be
fought over oil, as the need for water is fast surpassing the need for oil.
Being water wise means much more than simply watching the amount of water you use
when your local municipality imposes water restrictions. Anyone can and should do
this. To truly make a difference we must all do more, much more, to insure that
there is adequate water supply for generations to come.
Being water wise means learning to live in a way that that contributes to the
conservation of the limited water supply that we have remaining in Southern Africa.
It means harvesting rainwater, treating and re-using grey water, using drought
tolerant indigenous plants and grasses that require less water than alien species
in gardens, practicing and teaching others water conserving methods and simply
being responsible with the water that you do use everyday.
Please look at this list below to see just a few of the ways that you are make
your home a water wise environment and do your part to save our dwindling water
supply.
WATER WISE TIPS FOR THE LAWN AND GARDEN
- Collect Rainwater For Use Whenever and Wherever Possible
A 100 square metre roof area can catch up to 100 litres of fresh clean rain water for every millimeter of
rain that falls on it. That mean 10mm of rain is 1 000 litres of water saved with a rainwater tank!
- Divert Grey Water From Baths, Showers, Basins and Laundry To Lawns and Garden Beds
A grey water diverter or treatment system can save every litre of water used for bathing, showering etc and
put it to use for your lawn or garden. That can add up to a massive savings over time.
- Water your lawn only when it needs it
A good way to see if your lawn needs watering is to step on the grass. If it springs back up when you move,
it doesn't need water. If it stays flat, the lawn is ready for watering. Letting the grass grow taller
(to 3") will also promote water retention in the soil.
- Deep-soak your lawn
When watering the lawn, do it long enough for the moisture to soak down to the roots where it will do the
most good. A light sprinkling can evaporate quickly and tends to encourage shallow root systems. Put an empty
tuna can on your lawn - when it's full, you've watered about the right amount. Visit our natural lawn care
page for more information.
- Water during the early parts of the day; avoid watering when it's windy
Early morning is generally better than dusk since it helps prevent the growth of fungus. Early watering, and
late watering, also reduce water loss to evaporation. Watering early in the day is also the best defence
against slugs and other garden pests. Try not to water when it's windy - wind can blow sprinklers off target
and speed evaporation.
- Add organic matter and use efficient watering systems for shrubs, flower beds and lawns
Adding organic material to your soil will help increase its absorption and water retention. Areas which are
already planted can be 'top dressed' with compost or organic matter.
You can greatly reduce the amount of water used for shrubs, beds and lawns by:
- the strategic placement of soaker hoses
- installing a rain barrel water catchment system
- installing a simple drip-irrigation system
Avoid over-watering plants and shrubs, as this can actually diminish plant health and cause yellowing of the
leaves.
When hand watering, use a variable spray nozzle for targeted watering.
- Plant drought-resistant lawns, shrubs and plants
If you are planting a new lawn, or overseeding an existing lawn, use drought-resistant grasses.
Many beautiful shrubs and plants thrive with far less watering than other species. Replace herbaceous
perennial borders with native plants. Native plants will use less water and be more resistant to local plant
diseases. Consider applying the principles of xeriscape for a low-maintenance, drought resistant yard.
Plant slopes with plants that will retain water and help reduce runoff.
Group plants according to their watering needs.
- Put a layer of mulch around trees and plants
Mulch will slow evaporation of moisture while discouraging weed growth. Adding 5 - 10 cm of organic
material such as compost or bark mulch will increase the ability of the soil to retain moisture. Press the
mulch down around the dripline of each plant to form a slight depression which will prevent or minimize water
runoff.
- Don't water the gutter
Position your sprinklers so water lands on the lawn or garden, not on paved areas. Also, avoid watering on
windy days.
- Don't run the hose while washing your car
Clean the car using a pail of soapy water. Use the hose only for rinsing - this simple practice can save as
much as 550 litres when washing a car. Use a spray nozzle when rinsing for more efficient use of water.
Better yet, use a waterless car washing system. There are several brands now on the market.
- Use a broom, not a hose, to clean driveways and sidewalks
- Check for leaks in pipes, hoses, taps and couplings
Leaks outside the house may not seem as bad since they're not as visible. But they can be just as wasteful
as leaks indoors. Check frequently to keep them drip-free. Use hose washers at spigots and hose connections
to eliminate leaks.
- Water conservation comes naturally when everyone in the family is aware of its importance, and parents
take the time to teach children some of the simple water-saving methods around the home which can make a big
difference.
These are just a few of the ideas on how you can help save water in your home. If you know of
