The Sewer System: A Shared Responsibility
The City of Lakewood's Public Works Department safeguards the public sewer mains serving about 8,000 customers in north Lakewood. Other parts of Lakewood are served by a variety of service providers -- enter your address in My Neighborhood to find your sewer provider.
Half the sewer system is privately owned lateral lines, which are the cause of many sewage backups. Property owners are responsible for maintaining the entire length of their lateral line from their home or business to where it meets the sewer main under the street. Below are some best practices to prevent sewage backups.

Property Owner's Responsibility
Connects your home to the sewer main line by gravity flow. Some buildings require pumps to lift wastewater to the public sewer system. The property owner's responsibility for the lateral line extends beyond the property line to where the lateral line meets the sewer main. The lateral line should include a:
- Backflow prevention device: A valve that clamps shut to protect your home against sewage backups. The device is an industry best practice and is required by Colorado Plumbing Code for some properties.
- Sewer relief valve (SRV) and cleanout: If a sewer main blockage happens, this device diverts wastewater into your yard so it doesn't back up into your home. Check it regularly, especially after storms, to ensure it's operating and clear of obstructions.
Flush ONLY toilet paper and human waste! Do not flush anything else, including “flushable” wipes, hair, dental floss, cat litter, medications, feminine products and household hazardous waste. (Wastewater plants don’t remove medications, so they end up in the river!)
Never put egg shells, coffee grounds, fat or grease down your garbage disposal. They form a cement-like substance that can clog your line.
Hazardous Household Waste
It is illegal to put these items in the garbage or down any drain or toilet: Paint/solvents, cleaning products, motor oil, antifreeze, pesticides or fertilizers. Please visit rooneyroadrecycling.org to learn more about proper disposal of your hazardous household waste.
Roof Drain (Gutters)
Never connect the roof drain to the sewer.
Never connect a sump pump to the sewer.
