A water reuse project generates both monetary and non-monetary benefits. As a result, water reuse projects are often undervalued in comparison to other projects; significant opportunities for beneficial reuse are lost in this way (Sheikh et al., 1998). The non-monetary benefits are improved environmental quality and public health, reduced discharge of
nutrients into receiving water, lower drinking water treatment costs, conservation of recreational land use and tourism. The typical benefits for the wastewater agency and local authorities include (1) reduced effluent discharge and preservation of discharge capacity, (2) elimination of some treatment processes to meet mass limits, i.e. for nutrients, (3) reduction or elimination of major sewers owing to construction of satellite water reclamation plants, and (4) sale of recycled water.
