Who does it apply to? - Orono properties served by the city’s sanitary sewer system.
What does it entail? – Owners must schedule an inspection of their service line and make any necessary repairs to the service line. The inspection is aimed at detecting points of inflow or infiltration into the pipe (aka cracks, separations, root intrusions, or cross connections).
When does it apply? - When a property is being sold that does not already have a current certificate of compliance. A certificate of compliance, good for 10 years and will be issued after a successful inspection of a new or existing service line.
Why do we need the program? - The goal of this program is to reduce excessive flows that enter the sanitary sewer system as a result of Inflow and Infiltration (I&I) via private sewer service lines. Since sanitary sewer rates are based on the number of gallons that flow through the City sanitary sewer system, transporting and treating clear water from Inflow and Infiltration (I&I) is costly to everyone. Over the last 5+ years the City has been investing in sealing the city infrastructure, however this is not enough. We still continue to see high volumes in the system following wet weather events. While the city will continue to work to improve the public portion of the system, we must do something to address the I&I coming into the system from the privately maintained portion of the system. Metropolitan Council Environmental Services Division (MCES) estimates up to 80% of I&I makes its way into the systems from pipes on private property. The MCES, which provides regional wastewater collection and treatment for the metropolitan area, requires communities with excess I&I to invest in local reduction remedies and to urge compliance, and incorporates surcharges for communities with excess I&I.
How is your waste water treated? - Wastewater from private properties reaches the city sewer mains via private sewer service lines. The waste water then travels via city sewer mains and lift stations to reach MCES regional sewer mains. Then MCES mains in turn transport the waste water to the Metropolitan Wastewater Treatment Plant, operated by the MCES, where it is treated and released.
