Groundwater abstraction

Description

Storm water is collected in a series of three retention ponds via a large single roof structure. The grey water from the building is harvested into the first two ponds before being filtered through a vertical wetland into the third pond. The irrigation system is designed in such a way that it is extracted from the third pond at night to minimise evaporation and prevent interference with the daily distribution activities. To further reduce water consumption the landscape design and plant selection was carefully selected for their irrigation requirements. This system reduced the potable water demand by 75%. The remaining 25% is supplemented by borehole water. The result of this strategy saved the Client 100% expenditure in potable water and thousands of rands per year.
