We have seen a dramatic increase
in the number of enquiries regarding rainwater harvesting.
It has been growing in popularity for a number of years as
people have become more environmentally aware and since the
introduction of water meters. The interest was greatly boosted
last year with the introduction of water restrictions across
the South East.
People are now looking for more comprehensive systems
to store larger amounts of rainwater. Fontus offer a wide
range of solutions from 650 litre tanks, mid-sized 3000 litre
above or below ground tanks, through to vast 36000 litre underground
tanks.
There are two types of water that can be harvested:
1. Rainwater - collected from roof areas via downpipes
2. Greywater - collected from sink, shower, bath
and some washing machines.
Rainwater collection
Rainwater can be collected using the existing roof
drainage system. The rainwater is diverted from the downpipe
through a filter to remove any large leaf particles and any
other debris. Secondary filtration occurs within the tank.
The stored water is then pumped out of the tank via a floating
filtration suction unit. There is an overflow facility that
will divert the rainwater to the drain if the tank is full.
The water can then be distributed as needed around
the garden, usually to an irrigation system and to garden
taps.
The tank can be fitted with a mains water back-up
to ensure there is always adequate water for irrigation.
Greywater Collection
Due to the composition of greywater the filtering
process is more complex and requires a far more elaborate
filtration system.
