| The bigger the roof, the
bigger the catchment, the bigger the benefits. This
is why the Envireau system is so ideally suited to commercial
applications:
- Schools and public buildings
- Commercial offices
- Warehouses and factories
- Housing Associations
- Industrial developments
- Farms and agriculture
- Plant nurseries and garden centres

Benefits
Commercial premises generally have a greater demand
for non-potable water for cleaning and toilet facilities.
Conversely, by having a large roof area these buildings
possess a natural facility to recoup large amounts of
water and, in turn, deliver substantial savings.

No two buildings are alike and this is taken into account
when assessing the system's components. Each system
installation is bespoke, with carefully selected tanks,
filters and control systems. The monitoring and telemetry
can also be linked into building management systems.
Designed for Your Convenience
Whether it is from a cost-saving, environmental or
storm water management standpoint, our technical staff
will evaluate the site conditions and design a cost-effective,
easy to use system that is tailored for your specific
building application.
Each system is capable of being upgraded and can be
linked into future development expansion or potential
change of use.
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 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.

| 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).
