Combined greywater and rainwater harvesting

If neither sufficient rainwater nor sufficient greywater is available for the desired consumers, rainwater and greywater systems can be combined. As soon as no more rainwater is available, treated greywater is used to replenish the supply. If there is also no longer enough greywater available, the DVGW-certified RAINMASTER is used to switch to city water.
