New Gallagher Well Number 2 (West Marin Service Area)
Gallagher Well No. 1 went online in 2014 shortly after the completion of an approximate 1-mile long pipeline connecting the well site to the Point Reyes Treatment Plant. The New Gallagher Well No. 2 well provides much needed additional water supply capacity to the District. Well No. 2, located approximately 450 feet north of Well No. 2 is designed as a shallow well extending approximately 60 feet below the ground surface with a yield of 150 gallons per minute (gpm).
The Project will be completed in two main phases. Phase 1 includes drilling the well and installation of the well casing, screens and seals. The work was awarded on February 1, 2022 to Maggiora Bros Drilling of Watsonville. Phase 1 includes well development and testing to ensure proper water flow. Phase 2 will commence once the well drilling is complete and consists of construction of an earthen well mound, installation of the well pump assembly and associated piping to connect to the existing Gallagher pipeline. Several months of well start-up, testing, water quality analysis and eventual state permitting will occur as a final step prior to bringing the well online.
The project was awarded a grant under the California Department of Water Resources Small Community Drought Relief Program.
Lynwood Pump Station Motor Control Center
The Lynwood Pump Station is located at the intersection of South Novato Boulevard and Sunset Parkway in the center median. The electrical service and operational controls are over 40 years old and have gone through several temporary repairs over the years. To improve reliability the electrical systems and controls require replacement and relocation out of the flood prone area of the underground vault at the pump station. An above ground electrical control room has been designed to incorporate the historical design of the existing structure and incorporate modern architectural features. The project will include the construction of the new control room and landscaping of the median at the existing pump station location.
Crest Pump Station
The proposed Crest Pump Station project is intended to replace the existing School Road Pump Station, and involves construction of a new building, installation of three 20 horsepower pumps, manifolds, associated equipment and approximately 650 feet of 12-inch diameter and 100 feet of 8-inch diameter pipeline. The new pipeline will draw from zone 1 piping in Bahia Drive and discharge into the Crest system (zone 2) at the end of Cerro Crest. North Marin Water District has acquired a small parcel of land from the City of Novato and installed the electrical service to the site. Construction is projected to commence in late 2022.
This project will provide the following benefits:
- Increased pump efficiency thereby reducing energy costs
- Improved worker safety and access
- Addition of redundant pumping capacity
- Improved fire flow for reliability
San Mateo Tank 24” Transmission Main for Fire Safety and Reliability
The project involves installation of a 24-inch diameter main extending from the San Mateo Tank and connecting to existing distribution system piping in San Mateo Way. When San Mateo Tank was originally constructed in the 1960’s, a temporary 12-inch main was also constructed to connect the tank to the distribution system. At that time, additional development was planned along the slopes of Mount Burdell, and the existing 24-inch main in Palmo Way was to be extended to the tank as development occurred. Subsequently in the 1970’s, the Mount Burdell Preserve was purchased by the Marin County Open Space District and no further development occurred. The existing 12-inch main connected to the tank represents a hydraulic bottleneck in the system.
This project has all necessary permits and a federal grant had been submitted in April 2022. The construction for this project is planned for 2022.
Old Ranch Road Tank No.2
The FY20 and FY21 Capital Improvement Project budgets for Novato include design and construction of the Old Ranch Road Tank No. 2 project. This project consists of the design and construction of a 100,000 gallon stainless steel bolted steel tank to replace the existing aging 50,000 gallon redwood tank, as well as a new access road to the tank. The existing tank will be decommissioned once the new tank has been placed into service. The project includes additional fire flow storage to satisfy Novato Fire protection goals and is consistent with the Board approved 2018 Novato Water Master Plan. The project is currently under construction and will be complete by July 2022.
Leveroni Creek Embankment Repair Project
The Leveroni Creek Embankment Repair project is included in the District’s adopted FY 21-22 Capital Improvement Projects Budget. Leveroni Creek’s left bank downstream of the 8-foot diameter culvert outfall plunge pool is slowly eroding, threatening the structural integrity of the Stafford Treatment Plant and Indian Valley Golf Course access road. A similar project was completed in 2012 to protect the right bank of Leveroni Creek near the Stafford Treatment Plant’s centrifuge and reclamation basins across from the current project location. Leveroni Creek provides habitat for steelhead (a federally-listed salmonid) and other species, and the project requires permit approvals from the US Army Corps of Engineers, California Department of Fish and Wildlife, Regional Water Quality Control Board and the County of Marin. The Project design is complete and final environmental permits are mostly secured. Grant funding is being considered for construction which is scheduled for Summer 2022.
Oceana Marin Treatment and Storage Pond Repair Project
The Oceana Marin Treatment and Storage Pond Repair Project proposes to mitigate the impacts of extreme weather and earthquakes on the Oceana Marin Waste Water Treatment and Storage Ponds that occurred as a result of 2016-2017 heavy rains and wind generated waves. Emergency pond berm repairs were performed in 2018 as a temporary solution. The current project entails draining the treatment and storage ponds, clearing and grubbing the existing bank vegetation, armoring of the pond berms with stabilization fabric and rock rip rap to provide a long-term solution with a high degree of effectiveness. Project construction is scheduled for May– November 2022.
Lagunitas Bridge Pipeline
This project addresses the seismic vulnerability of a key drinking water pipeline that connects water wells and a treatment plant at Point Reyes Station with the remainder of the drinking water system in rural West Marin County. This pipeline serves the communities of Olema and Inverness, which are the main towns closest to Point Reyes National Seashore, as well as serving one of the Point Reyes National Seashore visitor centers which receives hundreds of thousands of annual visitors. The pipeline is currently connected to the Lagunitas Creek Bridge, which Caltrans must replace due to existing seismic risk.
Novato Boulevard Project
In conjunction with the City’s Novato Boulevard Improvement Project, North Marin Water District will be replacing existing water facilities in Novato Boulevard between Diablo Avenue and Grant Avenue. Existing water pipelines and appurtenances will remain for future reuse as a recycled water system.
