Planet Earth contains 320 million cubic miles of water, enough
to cover the entire globe 1000 feet deep. We ourselves are 97%
water when born and 75% water as adults. Yet water us a very
scarce global resource. Oceans, lakes, streams and rivers contain
98% of Earth’s water. The remaining 2% is in the soil,
the atmosphere, the bodies of living organisms or frozen in
glaciers and ice caps. Only 0.02% of the Earth’s water
is available for drinking. Millions of people do not have access
to safe, clean drinking water.

Rainwater falls from the sky for free, by simply filtering
it then storing it, you can water your garden or even pipe
it straight into your home and use the rainwater to flush
the toilet or do the laundry. Recycling your rainwater has
many advantages, first being; its free, you can store as much
as you want then reuse it how you want. Second is that rainwater
is softer then tap water, which means that if you were to
use the rainwater in you washing machine lime scale would
take longer to appear. If you were using the water for your
garden, then some plants respond better to rainwater than
tap water.
We use 70% more water today than we did 40 years
By reducing our water usage we will:
Save money
Reduce
the possibility of a drought, which will lead to a hosepipe
ban.
Reduce
the damage which is done to wildlife in wetlands, reservoir
and rivers

DIY Rainwater Harvesting In Garden
No matter how much it rains we always seem to need
more water for our plants and gardens. By collecting your
rainwater in an underground water tank, you we have a constant
supply of water. These rainwater harvesting systems can be
connected straight into you existing irrigation system them
will never have to worry about your plants and garden not
being water when you're on holiday.
Once your system is setup there is no end to the uses of
the water you save. You can connect a pressure washer to the
tap outlet and use the rainwater to wash your car or even
clean your patio.
Underground water tanks don't have to be sunk in ground;
they can be installed under patios or under decking. All accessories
such as water pumps, filters and fittings can still be installed

There are many ways in which householders can pollute waterways
e.g. via the sink, toilet, from the washing machine, dishwashers
or simply by dangerous disposal/application of chemicals directly
onto soil or into waterways. In houses, wastewater from sinks
and toilets for example, usually flows into either septic
tanks or into municipal sewage treatment plants. Under optimal
conditions bacteria break down the constituents in the wastewater
and the clarified effluent is returned to the environment.
However, many chemicals that are sold in the supermarket for
toilet cleaning or other detergents can affect bacteria in
the septic tank, leading to poor operation or even worse,
the total cessation of performance by the tank. When this
occurs, the dirty wastewater enters the chamber of the tank
where it receives incomplete treatment. It then flows into
the environment and may seep into the groundwater below or
into surface water.

Natural processes have always cleaned water as it flowed
through rivers, lakes, streams and wetlands. In the last few
decades, eco-engineers have designed wetlands that mimic natural
processes, for water quality improvement. Constructed wetlands
such as reed beds are used across the world to improve the
quality of point (direct discharge) and nonpoint (diffuse)
sources of water pollution. Reed beds are used for water purification
and are modelled on natural wetland systems. The can be applied
to the treatment of domestic sewage typically in conjunction
with septic tanks or other biological treatment systems. They
are also beneficial for wildlife by developing a new habitat
for wetland species of flora and fauna. |
