Maintaining Your Private Stormwater System
Stormwater systems are designed to collect and control runoff. They play a key role in preventing flooding, pollution and erosion. Stormwater systems include structures such as catch basins, ponds and ditches, which require periodic maintenance to ensure that they function properly.

Property Owner Requirement
Pierce County requires property owners to inspect and maintain stormwater systems on their private property. Pierce County inspects private stormwater systems at businesses and in residential developments to ensure they are functioning properly, and pollutants are not entering the drainage system and surface waters in Pierce County.

To schedule a courtesy inspection to ensure your system is functioning properly, call (253) 798-2725.

Best Management Practices
Best management practices are steps you can take to prevent runoff from coming into contact with pollutants. Examples include covering a pile of exposed soil to prevent erosion, moving drums of waste to a covered area, and having a spill kit on hand to prevent spills from spreading. 
Chapters and other documents regarding best management practices in the Pierce County Stormwater Management and Site Development Manual
