This paper describes a 144.6 liter/second (L/s) (3.0 million gallon per day (mgd)) water reclamation plant and a 35 L/s (0.8 mgd) reverse osmosis plant (RO). The water reclamation plant treats secondary treated wastewater discharged from the Goleta Sanitary District wastewater treatment plant. The RO plant further processes a portion of the effluent that will be produced at the water reclamation plant. RO treatment is needed to: (1) lower the chloride content of the tertiary effluent to less that 300 milligrams per liter (mg/l), for protection of golf course greens and sensitive plants; and (2) to provide water with reduced concentration of chlorides, sodium, sulfates, and other constituents to agricultural growers. The installed RO Plant will produce 35 L/s (0.8 mgd) of desalted water. The facility will discharge 9.6 L/s (0.22 mgd) desalted water to the agricultural growers and discharge 25.4 L/s (0.58 mgd) to reclaimed water storage tanks for blending with effluent from the water reclamation plant. 115.7 L/s (2.64 mgd) of blended effluent will be available to distribute to all other reclaimed water users.
