City of Rialto Septic-to-Sewer Disadvantaged Communities Project

The State Water Resources Control Board is serving as the Responsible Agency for the City of Rialto Septic-to-Sewer Disadvantaged Communities Project, designated under Project Number 8825-110, with funding provided to support the transition of approximately 221 residential properties from individual septic systems to a centralized municipal sewer system in underserved areas of Rialto, California. The project encompasses a full range of activities including administrative oversight, community outreach, feasibility analysis, environmental documentation, and detailed engineering design, all aimed at ensuring a thorough and equitable transition process that addresses public health and environmental concerns linked to aging septic infrastructure. Project implementation is being coordinated through a partnership between the State Water Board and the City of Rialto, with key contacts including Cedric Irving, Environmental Scientist at the State Water Board, and Sachin Chawla, Director of Utilities for the City of Rialto, who serve as the primary points of communication. The project is currently in the forecasting phase, with a posted date of May 29, 2026, and will proceed with comprehensive planning to confirm septic system locations, engage local residents, secure necessary permits, and develop technical designs that meet regulatory standards and community needs. All activities are designed to fulfill grant requirements while advancing equitable infrastructure improvements for disadvantaged communities in Rialto.
