Abstract: The water reclamation system receives waste water from a small residential type source, such as one or more homes, a series of apartments or road houses, and processes the water so that it meets the standards of state and federal regulatory agencies for non-domestic services. The treatment in accordance with the system starts with biologic and enzymatic treatment of the materials in the waste water stream. Next, bacteria is killed by chlorination. Thereafter, mechanical filtration improves clarity. Finally, ultraviolet treatment kills any remaining bacteria. The final flow is useful for irrigation, washing of structures and automobiles, filling swimming pools, and for returning to toilet tanks for flushing purposes. The system includes a provision for backwashing the filters.
