Capital Improvement Projects

Projects that are under construction or in final design

During the next five years, the District will carry out over $30 million in critically needed improvements to our community’s sewer pipelines, pumps, manholes and treatment facilities. The goal: to upgrade the sanitary systems so that it will continue to reliably protect public health and the environment, while achieving regulatory requirements.

Below are links with updates on current construction projects.

Secondary Sediment Tanks Rehabilitation Project

The District awarded a contract to Nute Engineering in January, 2016, for $52,408 to complete project plans and specifications for bidding the project. The secondary sediment tanks provide secondary treatment of waste water to reduce solids. There are two 80 foot long and 20 foot wide tanks which allow flows to slow so that solids can settle out. These solids are captured and removed by a collector system which was constructed in 1986. This system has reached the end of its useful life and has been problematic for maintenance and reliability. The new collector system will include upgraded technology and materials to ensure reliable operation of this critical treatment process. Construction will take place in the summer of 2016.

Highway Booster Pump Station Rehabilitation Project

The pre-design of Highway Booster Pump Station has been completed. The District awarded a contract to Carollo Engineers in November, 2015, for $192,406 to complete project plans and specifications for bidding the project. Highway Booster pump station was originally constructed in 1952 to pump sewage from portions of Shoreline Highway and Marin City. This station requires rehabilitation to ensure reliability and to eliminate the infiltration of ground water into aging underground structures. In addition, the new station will improve safety and reduce maintenance costs through the elimination of confined space entry currently required to maintain equipment. Construction will take place in the summer of 2016.
