Our drains carry stormwater off of Seattle's streets, and our sewer mains carry your home or business' wastewater for treatment. We work to prevent sewer overflows, quickly respond to flooding, and use Green Stormwater Infrastructure to better handle Seattle's rain. Find out how your side sewer connects to our sewer mains.

Your sewer bills are based on actual water usage during the winter period (November through April). For stormwater management (drainage), the City of Seattle charges property owners a fee based on each property's estimated impact on the drainage system.
