North Mesa Sewer Canyon Drop Replacement - Los Alamos County

This project will replace two steel sewer pipes that are attached to the walls of North Mesa. This canyon drop sewer was constructed in the 1970 with construction methods available at the time. The pipeline is impossible to maintain and in the event of a failure a significant release of sewage to the environment would occur. In preparation for an expected 400 new homes that will be built on North Mesa, the existing sewer drop will be replaced with a new polyethylene sewer line installed by the horizontal directional drilling (HDD). HDD is a trenchless technology which has minimal environmental impacts and has been used successfully by DPU to build pipelines from the mesa tops to canyon bottoms. The project will potentially be funded by County economic developments funds. This project is in included in the County of Los Alamos FY 2023 - Adopted Budgets. As of October 21, 2022, further details regarding design and construction have not been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
