Rainwater Harvesting is the collection and storage of rainwater that typically would otherwise flow down gutters into the drain. SDS commercial rainwater harvesting systems are able to reduce consumption and improve efficiency of water use, saving money and enhancing corporate sustainability as well as reducing mains water consumption by up to 30%. Rainwater harvesting can be incorporated into new build developments and selected existing buildings where there is sufficient roof space to capture rainwater.
How does it work?
SDS WM1000’s control software incorporates a level sensor which ensures rainwater is prioritised as the primary water source. An integral AA-rated break tank ensures a constant water supply is achieved by intelligently switching to mains water when rainwater is unavailable.
By assessing your geographic and infrastructure suitability, we can design and install a bespoke system to collect and filter rainwater, feeding it back into the property through a simple yet robust treatment system. This ensures that only the cleanest, soft water is utilised for non-potable purposes such as vehicle washing, flushing toilets and irrigation.
To enable a system to be designed, an understanding of the roof size, volume of water consumed on site and potential use of the captured rainwater is required. Due to the volume of roof area and water required, rainwater harvesting is most often adopted by retail outlets, distribution centres or large commercial buildings. Its benefits are greatest, and the payback period minimised, in geographical areas with both historically high rainfall and high water supply charges.
