Rehabilitation of Small Lift Stations in Mexicali, Baja California

Status: Under construction

Background

CESPM operates the water and wastewater systems for Mexicali, Mexicali Valley and San Felipe, Baja California. The Mexicali wastewater system consists of approximately 1,500 miles of sanitary sewer lines, 14 main lift stations and 22 small lift stations, serving more than 294,421 connections in the city of Mexicali with coverage reaching approximately 95.46% of households. The utility also has two wastewater treatment plants with a combined maximum capacity of more than 2,164 liters per second (lps) or nearly 50 million gallons per day (mgd).

Description

The project consists of the rehabilitation of 12 small lift stations—Aurora, Calle G, Campestre, Centro Civico, Cipresito, Esperanza Agricola, Hidalgo, Jardines del Lago, Nueva Esperanza, Zacatecas, San Marcos and Coronado. Additionally, all lift station sites will include building improvements, such as updates to the control room, wet well rehabilitation, installation of travel hoist equipment, a perimetral fence and site improvements to accommodate access for vacuum trucks.

Objective

The purpose of the Project is to improve the wastewater collection facilities and infrastructure serving an estimated 41,640 existing residential wastewater connections. It will reduce the risk of pump failures, sewage backups and potential discharges of up to 380 liters per second (lps) or 8.7 million gallons per day (mgd) of untreated or inadequately treated wastewater, thereby helping reduce water pollution and the risk of waterborne diseases, as well as transboundary wastewater flows to the United States in the New River, an impaired water body.
