Water Wise Re-use is the new buzzword in
sustainability, and water re-use
irrigation sectors. Water conservation and
is becoming the new norm in all
demand management is a theme
that needs to be integrated into all
aspects of business and economy,
including that of landscape design.
Rain- and stormwater harvesting,
Re-using water in the landscape and greywater re-use are two
alternative sources of water than
can be used for irrigation of gardens
and landscapes. Rainwater can be
collected in raintanks and pumped to
areas of the landscape that require
it. Stormwater can be directed within
the landscape by designing swales
and berms in suitable locations.
Greywater from baths, showers,
laundries, and bathroom taps can
be re-directed into the landscape.
A household of four people can
generate around 300 litres of
greywater a day. There are a number
of greywater treatment systems
available on the market, as well as
simple, cost-effective DIY solutions.
Greywater needs to be used safely
and responsibly and should not be
stored for longer than 24 hours if
untreated.
Greywater should be used in
specially designed irrigation systems
that are separate from potable water
irrigation systems and could include
a sub-surface pipeline network and
non-clogging drippers.
There are many water-saving
alternatives to potable water use in
landscape irrigation that will save
you water and money.
Be Water Wise.
