Within the City of Kirkland's sewer district, the city operates and maintains the public sewer infrastructure including public sewer mains. The customer owns and maintains the private side sewer pipe that begins at the public sewer main and connects to the house/building. This includes the entire side sewer pipe on private property and in the public right-of-way.
Plumbing on private property is the property owner's responsibility, including but not limited to plumbing fixtures such as toilets, sinks, bathtubs, and showers, drains, sewer cleanouts, and pipes.
