Utility Systems

The Utility Systems Division is responsible for planning, designing, constructing, operating and maintaining the city's water, wastewater (sewer) and surface water (stormwater) systems. These systems deliver safe drinking water, manage wastewater and protect local lakes, rivers and streams in the City of Renton. We help residents, businesses, and developers with everything from new service connections and final utility bills to construction standards and system planning. We're here to help with any questions about your water, sewer, or stormwater services.

Escrow inquiries - final utility balances

When a property is sold, the escrow process and final utility checks show how much is owed for water, sewer, and stormwater services, including any connection or assessment fees. This helps ensure all utility charges are settled before closing. The sections below explain these charges and how to request information.

Standard details

The City of Renton provides approved drawings that show how water, sewer, and stormwater systems are designed, fabricated, installed, and constructed. These drawings are available to help contractors, developers, and property owners understand the city's standards and ensure work is done correctly.
