Klargester Envireau rainwater harvester brochure

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 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).

Commercial Applications
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.
