On -Call CM/I LB -MUST Treatment Plant and Wetlands - AKM provided quality control and constructability review of the proposed treatment plant and conveyance system design of the 90 percent design package and is currently providing construction management and inspection during construction. The treatment is designed with the ability to treat both brackish and non -brackish influent flows through separate treatment trains. The treatment process train consists of influent strainers, ceramic membrane ultra -filtration (UF), and an advanced oxidation process (UV/AOP). The ancillary processes include process pumping, process storage tanks, chemical feeding, and air supply. An RO system can be added to the treatment train in the future, downstream of the UV/AOP, to reduce TDS of the effluent and/or provide additional barriers for potential potable reuse. The ceramic membrane system, which consists of two (2) 1 million gallon per day (MGD) units as well as the UV/AOP were pre -purchased by the City. The treatment facility will be housed within a 9,000 square foot cement masonry unit building with electrical, chemical and control rooms, and will include an HVAC system. Also being constructed is a wetlands and walking path. EQUPPING OF WELL 16 AND TREATMENT PLANT CITY OF PARAMOUNT — 16400 COLORADO AVENUE, PARAMOUNT, CA 90723 CONTACT: MS.
