Home Systems
Easy to install, simple to maintain, automatic in
operation; the domestic Envireau system has been
developed to provide the homeowner with a
'fit-and-forget' system, ensuring an automatic
supply of harvested rainwater.
Designed to be as user-friendly as possible, the system utilises
much of the existing pipework within the building. The main
requirement being the installation of a rainwater storage tank
(with internal pump), selected to meet the roof area's water
catchment yield and household requirements.
System Options
The Envireau system has two primary options; the Gravity
System uses an elevated header tank to store filtered water
after the main tank. The Direct System pumps water from the
main storage tank and is used where a header tank is
impractical.
Envireau Direct System
The Direct System is also suitable for both domestic and
commercial applications.
This system is used where it is impractical to have a header tank
and therefore filtered rainwater is pumped direct from the holding
tank to the various appliances. When the holding tank is
running dry there is a small automatic charge of mains
water into the storage tank to ensure the system
never runs dry.
The main advantage of this system is that
rainwater is delivered to the appliances
at mains pressure (3.5 bar).

Envireau Gravity System
The Gravity System is ideal for both domestic and
commercial applications. It has a major advantage in that in
the event of a power failure on site (or the rain stocks running
dry) the system will automatically switch to mains water
supply to ensure a continuity of service.
The header tank contains two independent valves operating
both the mains and rainwater supply. The system will always
draw on rainwater first.

Keep your garden growing with Raintrap
Rainwater caught straight from the sky is the best water you can give to your garden. Captured before it hits the ground, rainwater is free of many pollutants that plague surface and underground water supplies and almost always exceeds the quality of ground or surface water.
Rainwater typically has very low hardness levels, which reduces the use of soaps and detergents, and eliminates the need for a water softener.
What's more, it is not subject to the annual Hosepipe Bans and free to use !
Developed for the gardener, Raintrap is the simplest of the Envireau rainwater harvesting systems. It can save thousands of gallons of tap water each year, and save money and energy, too. (Lawn and garden watering typically consume 40 percent of total household water use in the summer.)
Your plants will love the warm, soft, chlorine-free rainwater and Raintrap makes watering easy for you too!
