Overview

Summary

Request for Bids

West Basin Municipal Water District (West Basin/District) is accepting bids for the Torrance Refinery Water Recycling Plant Sulfuric Acid Day Tank Area Rehabilitation and Replacement Project.

Background

This project focuses on improvements to the sulfuric acid day tank area at the Torrance Refinery Water Recycling Plant (TRWRP). The scope includes installing a temporary bypass system, removing existing equipment in the day tank area (including pumps, piping, and the tank), rehabilitating the concrete containment structure, and installing all required equipment—both existing components and new replacements as needed.

These improvements support regulatory compliance, best management practices for chemical storage and operational efficiency, enhance safety for operators and other personnel, and strengthen overall environmental protection.
