Abstract
A water economizing system for new or existing buildings where the waste lines of lavatory sinks, showers and clothes washing machines are connected to a storage reservoir for accumulation of water therein. This accumulated water is filtered and treated and thereafter used for the operation of water closets of toilets, the storage reservoir providing for the removal of solids and foam by flushing action at the top and subsequently by the gravitational separation of solids which are periodically flushed from the bottom of the reservoir into the sewer. The pumping action which delivers the accumulated water to the water closets of toilets may optionally be hydraulically operated by a portion of the water drained to the storage reservoir.
Claims11
A water conservation system comprising:
- means distributing clean water to selected household facilities for use therein;
- drain means in said selected facilities other than facilities which have their primary function for the disposal of human waste for delivering said water in the form of gray water from said selected facilities through a inlet conduit of a settling tank at a level below said facilities for the filtration and gravitational separation of solids therefrom;
- water pump means associated with said settling tank, said pump means having further conduit means for receiving water from said tank and delivering pressurized water to a storage receptacle having a pressure level sufficient whereby it can deliver gray water to said other facilities;
- a readily removable filter in said tank immediately below said inlet conduit means;
- and removable cover means for said tank whereby said removable filter can be removed and replaced by a fresh filter which is supported immediately below said inlet conduit means.
A water conservation system installation in a building which comprises a washing facility and a drainage conduit therefrom located at a first level, said conduit providing liquid passage means to a second level substantially lower than said first level, a storage tank receiving said liquid passage means at said second level, pump means associated with said tank adapted to convey water therefrom to the water inlet of a water closet, rain collection means on the roof of said building, rain water passage means with a rain water container and sediment trap means therein leading from said collection means to said tank, timed automatic means for periodically removing gravitationally separated solids from said tank, said tank having a conical bottom with a drain at the lowest part thereof, said solids being removed through said drain, said conical bottom having an included angle of not more than about 120.degree..
A water conservation system installation in a building which comprises a washing facility and a drainage conduit therefrom located at a first level, said conduit providing liquid passage means to a second level substantially lower than said first level, a storage and settling tank receiving said liquid passage means at said second level, pump means associated with said tank adapted to convey water therefrom to the water inlet of a water closet, said tank being generally cylindrical and having a longitudinal axis between 10.degree. and 45.degree. relative to the horizontal, an outlet from said tank to said pump means which enters said tank at substantially the lowest part thereof, and a drain from said outlet having a valve therein adpated for periodically flushing non-liquid material settling from water contained in said tank.
