Title
Resolution approving a Memorandum of Understanding (MOU) between the City of Littleton and Littleton/Englewood Wastewater Treatment Plant defining sanitary sewer interceptor ownership
Body
Presented By:
Mark Relph, Public Works and Utilities Director
POLICY QUESTION:
Does city council support defining the ownership and maintenance of the sanitary sewer interceptor pipe, upstream from the Littleton/Englewood Wastewater Treatment Plant (LEWWTP), as being the City of Littleton's property and responsibility?
BACKGROUND:
When the interceptor was built in the 1970's, a section of this pipe from the siphon under Little Dry Creek to the LEWWTP was never formally owned or expressly defined as maintained by any entity. This pipe is now in need of repair. A small section of this 66" interceptor pipe just north of the City of Littleton's siphon (see fig. 1) collapsed in January, 2016 and emergency repair was completed by the City of Littleton.
Staff prepared the design and construction plans for the permanent repair north of the city's siphon to a designated manhole just inside the LEWWTP per the proposed MOU. Ownership and maintenance responsibility for this pipe should be formalized. The construction contract for the repair has been prepared and is pending approval of the MOU before the contractor is given a formal "Notice to Proceed." At that point the contract is executed and the city incurs the cost of repairs.

The city has ownership of the interceptor upstream (sou...
