Environmental Compliance

The City of Modesto’s Water Quality Control Division is charged with maintaining water quality for the present and future generations. The City has two (2) major systems, the wastewater system and the storm drain system. Wastewater is treated and either discharged into the river with pollutants removed, or used for irrigation. Storm water and urban runoff flow from our City directly into the storm drain system via rockwells or catch basins. Any water that enters a storm drain flows directly to our local creeks, rivers and waterways UNTREATED. Best Management Practices (BMP’s) are designed to inform our community of procedures and practices that will protect our environment when they are at home, at work or at play. Please follow the links to find this vital information.
