Rainwater Harvesting & Water Storage
The KingspanWater
Domestic Envireau Rainwater Harvesting system
has been
designed as a low cost installation for self-build projects and residential developments.
It works by taking the rain from your roof gutters, filtering out leaves and debris and
storing the water in an underground tank. This is then pumped into the house to be
used for non-potable applications such as toilet flushing, washing machines and garden
use. If the tank runs empty, the system automatically switches to mains supply.

The
Envireau Direct System
is used where it is
impractical to have a header tank for example in homes
that have converted attic spaces and no room for a
header tank. Therefore the filtered rainwater is pumped
direct from the holding tank to the various appliances.
The main advantage of this system is that rainwater is
delivered to the appliances at mains pressure or higher.
The
Envireau Gravity System
is ideal for domestic
applications which use an elevated header tank to store
filteredwater after themain tank. It has amajor advantage
in that in the event of a power failure on site (or the rain
stocks running dry) the systemwill automatically switch
tomains water supply to ensure a continuity of service.
The water from the header tank will flowby gravity to the
serviced appliances. The systemwill always draw from
the rainwater supply first.
