Abstract: This invention relates to a water reclamation system for reclaiming grey water and ground water from sources associated with a domestic dwelling and subsequently utilizing such water in conjunction with a landscape irrigation system. The system generally comprises a storage reservoir which is fluidly connected to a main irrigation line comprising the landscape irrigation system. The reservoir includes a number of inlet conduits connected thereto which are in fluid communication with grey water sources from within the dwelling and with yard drains which receive ground water. The reservoir also includes an overflow line interfaced thereto which is adapted to drain excess water from within the reservoir to a main sewage line. The water provided to the irrigation system via the storage reservoir is supplied only as an alternative to water which may be supplied thereto via a main water line.
