ABSTRACT OF THE DISCLOSURE: A water recovery system in which drain water from appliances, sinks and bathtubs are conserved in a storage recovery tank for treatment and reuse as a water supply for toilets. The drain water is directed through an outlet to flow over a pivoted grate that is mounted above the top opening of the storage tank, with the grate formed of spaced inverted T-shaped ribs and normally held at an acute angle, such as ten degrees, to the horizontal plane by a spring so that debris retained on the grate is washed dia- gonally downwards off the top surface of the grate to fall off the lower end of the grate into a debris-collection and tank overflow unit. The drain water, itself, falls between the grate ribs into the storage recovery tank. The grate is linked to an outlet valve leading from a liquid chemical storage tank so that liquid treatment chemicals in the chem- ical tank are released into the storage tank during periods of drain water flow onto the grate, when the grate is pivoted to a greater angle, such as twenty degrees, to the horizontal by the weight of drain water flowing on and through the grate. The grate is also linked to a first float which prevents the grate from opening the release valve of the chemical tank when the storage tank is full. A second float in the storage recovery tank admidst fresh water into the tank, when the tank level falls below a pre- set minimum. A pump operated by a pressure switch automa- tically supplies water to the toilet supply line upon demand.
