Water usage in the home

- The most efficient and sustainable way to reduce a home mains water supply usage is to install a rainwater harvesting system that creates a constant replenishment system such as dws. Garden and outdoor usage, toilet and laundry supply from a rainwater harvesting tank is the most effective way to achieve a reduction in household mains water dramatically. - When the rainwater harvesting system is used in conjunction with a mains interconnection device such as the dws controller, a more compact tank would suffice as supply security is provided. - The unique dws rainwater harvesting system reduces the demand for and dependence on mains supply and being highly efficient while utilising rain supply greatly benefits the environment. - dws systems allow more appropriate sizing for high-density sites where space is at a premium, but return maximum potential to reduce mains water usage.
