Specifications include, but are not limited to: The CHLORINE CONTACT TANK EXPANSION PROJECT AND MEADOWLARK WATER RECLAMATION FACILITY CONVERSION TO SODIUM HYPOCHLORITE PROJECT (Work) consists of the expansion of the existing chlorine contact tank and the construction of a new sodium hypochlorite storage and feed facility and removal of an existing chlorine gas storage and feed facility at the Meadowlark Water Reclamation Facility in Carlsbad, California, and the modifications and demolition of various components, as fully described in the Contract Documents (Work). Chlorine Contact Tank Expansion Project (Work Order No. 250264) The Meadowlark Water Reclamation Facility (MRF) has two existing chlorine contact tanks (CCTs), which is the final recycled water treatment process responsible for disinfection. The CCTs convey a peak flow of 5.0 million gallons per day (MGD). Successful completion of the CCT Expansion will provide a third CCT basin to the system, per Plan resulting in a 1.5 MGD flow capacity increase to the disinfection treatment process. Conversion to Sodium Hypochlorite Project (Work Order No. 213334) MRF currently uses 100% chlorine gas as disinfectant to meet State regulations for treatment to reclaimed water standards. The Project will convert the existing chlorine gas storage and injection system to bulk storage and injection of sodium hypochlorite (12.5%) solution. The existing chlorine gas equipment, weight scales, chlorinators, scrubber, distribution piping, and appurtenances in the chemical building will be demolished, per Plan.
