Commercial ApplicationsThe bigger the roof, the bigger the catchment, the bigger the benefits. This is why the Envireau rainwater harvesting system is so ideally suited to commercial applications:
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 rainwater harvesting 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 rainwater harvesting system is capable of being upgraded and can be linked into future development expansion or potential change of use. System Options The Envireau rainwater harvesting 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 SystemThe Direct System is also suitable for both domestic and commercial applications. This rainwater harvesting 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 "Multi User" System
The "Multi User" System is used where one Envireau Gravity System is used to service up to 5 properties from one tank. This system is used most often on Housing Association Developments where the roof areas are small and cannot justify a system for each property. A landlords electricity supply must be available for this system.
