Keep Our
Truckee River

Only Rain in the Stormdrain

Keep our Truckee River Clean!

The Truckee Meadows region has two drainage systems — the sanitary sewer system and the storm drain system, known as a Municipal Separate Storm Sewer System (MS4). The MS4 is designed to carry rainwater away from city streets and into the Truckee River. Because our stormwater is not treated, it can carry urban pollution directly into the River. Using Best Management Practices (BMPs) improves water quality and will ensure a cleaner environment and better quality of life for our children.

About the Stormwater Program

The City of Reno, Sparks, and Washoe County are partners in implementing the Stormwater Management Program (SWMP) throughout the Truckee Meadows. The program goals are to reduce pollution to the Storm Drain System, technically called the Municipal Separate Storm Sewer System (MS4). The Stormwater Permit Coordinating Committee (SWPCC) meets regularly to implement the program.
