McMicken Heights Well & Treatment plant consists of the construction of a treatment facility nearby for the removal of iron and manganese from the water. The proposed treatment facility will include a pressurized filter vessel containing greensand and anthracite media; a 0.8 percent sodium hypochlorite on-site generation system and feed system; caustic soda and fluorosilicic acid chemical feed systems; a backwash recycle system utilizing a 75,000 gallon below-grade concrete reservoir; electrical panels and controls for filter and process automation; and backup power supply. The approximately 1,530 square foot treatment building will be constructed of CMU block with wood trusses and a metal roof. The facility will contain four rooms: 1) mechanical/laboratory/electrical; 2) pH adjustment; 3) fluoridation; and 4) chlorination. Site work will generally include raw and treated water utilities; power, signal, sewer and storm utilities; additional fencing; gravel driveway; site grading; security improvements; and landscaping. Power supply and automatic control improvements will also be included in this project.
