Water Harvesting and Geothermal Heating and Cooling
Hanson EcoHouse
The Hanson Formpave Aquaflow Sustainable Urban Drainage System (S.U.D.S.) allows heavy rain to infiltrate through a permeable concrete block paved surface into a unique sub-base and collect in a tanked area that combines with a layer of flexible piping connected to a ground source heat pump to provide space heating and domestic hot water.
The water in the Formpave system is cleaned by filtration and microbial action and is also suitable for secondary non-potable uses such as flushing toilets and watering soft landscaping. Infiltration is achieved by a thermally-bonded, nonwoven geotextile, specifically developed to optimise the cleansing of water entering the system. The various characteristics have been combined to create a unique geotextile that aids the development of the naturally occurring microbes, and offers them refuge during periods of drought. The system is underlain by an impervious plastic membrane to collect the water.
