About this file
This file is a construction plan document prepared by West Basin Municipal Water District for the JMMCRWRP Sodium Hypochlorite Tank Replacement Project. The plans consist of nine sheets including a title sheet with vicinity and location maps, general notes, an overall site plan, bypass plans and elevations for temporary tank operations, demolition and proposed mechanical plans, final tank plans and elevations, and miscellaneous construction details. The project site is located on Wilmington Street and involves the removal and replacement of an existing sodium hypochlorite storage tank and its foundation with associated appurtenances. A temporary bypass system must be installed to maintain plant operations during the tank replacement work. The plans were designed by civil engineers and plotted in June 2026, with specific notation that contractors must verify the precise location of existing underground utilities in the field prior to construction and must contact the Underground Service Alert of Southern California at least two working days before excavation activities.
The project must be completed within 410 calendar days as specified in the related solicitation. The construction plans serve as the technical specifications and design standards for bidders responding to the Request for Bids issued by West Basin Municipal Water District. These plans detail the engineering requirements, site conditions, bypass procedures, mechanical systems, and construction details necessary for contractors to prepare comprehensive bids and execute the tank replacement work in compliance with district standards and applicable regulations.
