The collected rainwater can be used for a variety of non-potable applications such as toilet flushing, process water, cleaing, washing & gardening. This alone will save approximately 50% + of water use in domestic premises and much more in a commercial premises.
Soft rainwater can decrease detergent use, increase the lifespan of household appliances and clean cars with no streaking.
How Do Rainwater Harvesting systems Work?
Rainwater is collected using your roof & gutters. The soft rainwater is then funneled to an under/over ground BMS GRP Tank. Leaves and other debris should be removed before they reach the tank. This can be done by the BMS Purain Hydraulic Jump Filter range which ensures 98% capture of available rainwater. The 100 mm Purain Rainwater Filter can be pre-installed in the tank for ease of installation. The Purain HD Jump Filters can be fitted in the ground beside the tank without the need for a concrete surround or seperate manhole, which is the requirement for most other systems. Once filtered, the rainwater then percolates slowly upwards from the bottom of the tank.
A pumping system is then required to pump the rainwater to a header tank (indirect/gravity supply) or direct to the appliances such as toilets.
To properly determine the tank size most suitable for your house/premises there are a number of considerations such as roof area, average rainfall, number of occupants/staff and potential uses of the rainwater, which need to be considered.
