The only Rainwater Harvesting System supplier you will ever need

Horizon House - Environment Agency HQ

Horizon House is the Environment Agencies National Office in Bristol City Centre.

The building is said to embody the environmental principles at the heart of the agencies work. As a result, Horizon House won the 2010 BREEAM Office Award for being one of the most environmentally friendly offices in the UK.

The rainwater harvesting system reduces the mains water consumption by collecting and storing rainwater for use in toilet flushing. The new building uses a great deal less mains water than the offices it replaced due to the water saving measures they have put in place.
