Eco Cistem enables additional credits to be claimed under BREEAM’s WAT 01 category.

Eco Cistem could provide two extra BREEAM credits and as many as five when used with other water saving devices.

WAT 01 aims to reduce the consumption of potable water for sanitary use in existing buildings from all sources through the use of water efficient components and water recycling systems.

BREEAM schemes are certified on a scale of Pass, Good, Very Good, Excellent and Outstanding.

The more credits gained, the higher the BREEAM rating.
