A rainwater tank of relevant size to anticipated frequency of rain events is connected to your home. Pumps and valves ensure continuity of water delivery, and maximum space in the tank to collect the next rainfall. Overflow water can be used in ponds and other landscape features like drainage swales to monopolise the water on your site, and thus reduce water sent to the street (sea). Tapware, WC cisterns, and shower heads are selected to reduce the outflow of water to a minimum without compromise to your shower experience.
