Novato South Service Area - Hamilton Field. It is proposed that North Marin Water District will provide recycled water service to the Hamilton Field area through the following roads and areas:
- Construction of a pipeline from the LGVSD Recycled Water Treatment Facility north along the levee adjacent to Miller Creek, and along the existing railroad grade to South Oakwood Drive.
- The pipeline would provide a loop system through Hamilton Field along South Oakwood Drive, Hangar Avenue, and the Main Gate Road.
- At the Palm Drive intersection, a pipeline would connect to the existing Reservoir Hill Tank, located north of the Hangar Avenue/Palm Drive intersection, and spur pipelines would be installed within Palm Drive.
- Primary roadways that would be affected include South Oakwood Drive Hangar Avenue and Main Gate Road.
Novato North Service Area. It is proposed that North Marin Water District would implement recycled water service in the Novato North Service area. Key facilities and roadways that would be involved, include:
- A pipeline would be routed from Atherton Avenue to Olive Avenue under Highway 101, and north on Redwood Boulevard to San Marin Drive to serve Fireman's Fund.
- A separate pipeline would be routed on H Lane to serve the Valley Memorial Park Cemetery. A booster pump would be installed at Atherton Avenue and the distribution system would be connected to the existing Plum Street Tank, which would be rehabilitated to provide storage.
- DeLong Avenue and S. Novato Boulevard would also be affected.
Novato Central Service Area. It is also proposed that North Marin Water District would implement service in the Novato Central Service Area through construction of a recycled water distribution system. Key areas and roadways that would be involved, include:
- Wastewater Treatment Plant south to Rowland Boulevard and the Vintage Oaks shopping center, and across U.S. 101 to serve urban users west of U.S. 101.
- Davidson Wastewater Treatment Plant, a pipeline would be installed along Novato Sanitary District's existing easement, crossing under U.S. 101 from Rowland Boulevard to Redwood Boulevard.
- A recycled water trunk line would then extend north through Novato to deliver recycled water to Novato High School and other irrigated playing fields, with a line extending south along Redwood Boulevard.
- A new pipeline would connect the Davidson Wastewater Treatment Plant with the North Service Area pipeline in Olive Drive via Lea Drive or McClelland Drive. This would allow continuation of recycled water service to the Stone Tree Golf Course.
Sonoma Valley County Sanitation District serves:
Existing reuse areas plus Sonoma Valley and Napa Salt Marsh.

Sonoma Valley Recycled Water Project. The Sonoma Valley County Sanitation District completed an EIR in 2007 for the Sonoma Valley Recycled Water Project in southern Sonoma Valley, including the city of Sonoma and unincorporated portions of the county. The project as described in the EIR involves extending the recycled water pipelines from the District's Wastewater Treatment Plant to deliver recycled water to an increased number of property owners.
It is anticipated that if fully constructed, the project could provide up to about 2,750 acre-feet per year of recycled water and expand the acreage currently irrigated with reclaimed water from 3,600 acres to about 9,100 acres.
The EIR includes analysis of 34 miles of pipeline, construction of storage reservoirs next to the District's Treatment Plant, and construction of a booster pump station and a distribution pump station.
The EIR also examined a provision for additional pond storage within the Sonoma Valley. The Phase 1 Implementation Plan includes specific elements of the project, including construction of 17 miles of pipeline, additional storage at the District's Treatment Plant and construction of additional pumping capacity for distribution. These facilities are consistent with those analyzed in the District's EIR that was certified in December 2006 by the District Board of Directors.
Napa Salt Marsh Restoration Project -- Recycled Water Pipeline. The California Coastal Conservancy, U.S. Army Corps of Engineers, and California Department of Fish and Game are implementing a salinity reduction and habitat restoration project for the 9,460-acre Napa River Unit of the Napa-Sonoma Marshes Wildlife Area. The Napa River Unit is located at the northeast edge of San Pablo Bay, next to the Napa River. The purpose of the project is to restore a mosaic of habitats, including tidal habitats and managed ponds, and provide for better management of ponds in the Napa River Unit to support populations of fish and wildlife.
An EIS was prepared and approved in June 2004. The Water Delivery Option examined as Phase 1 in the Sonoma Valley County Sanitation District EIS includes the annual delivery of about 2,000 to 3,000 acre-feet of tertiary recycled water from the Sonoma Valley County Sanitation District for salinity reduction and subsequent agricultural production.
Proposed facilities under the Phase I of the NBWRA Program Implementation Plan include construction of a new pipeline from the existing District ponds near the intersection of the Northwestern Pacific Railroad Authority and Ramal Road for about 4.5 miles to a salt pond mixing chamber. An existing 18-inch pipeline extends from the District's Wastewater Treatment Plant to the ponds. Project implementation would include construction of a new pump station at the ponds and installation of an 18-inch pipeline along the south side of the railroad tracks for about 3,100 feet to Skaggs Island Road. At this point, the pipeline would cross to the north side of the railroad tracks and continue east along the north side of the railroad for about 2.3 miles until it reaches the access road for Ponds 7 and 7A. The pipeline would cross to the south side of the railroad tracks and continuing south along the access road for approximately 4,200 feet, terminating at the mixing chamber.
Napa Sanitation District serves:
Milliken-Sarco-Tulocay (MST) Creek area, Napa Salt Marsh and Carneros East.

The original proposal for the area, called the Phase I MST Project, described a looped pipeline system using existing roadways, with one segment extending west along First Avenue and the second segment extending east along Third Avenue; both segments would then merge along Hagen Road north of the Napa Valley Country Club.
Under this plan, four booster pump stations would be constructed to maintain pressure throughout the distribution system. Pump stations would be located on Imola Avenue, Wild Horse Valley Road, East 3rd Avenue, and 3rd Avenue.
Potential recycled water users include the Napa State Hospital, the Napa Valley Country Club, and all agricultural parcels along the proposed pipeline route.
The Smaller MST Local Project. Recent outreach efforts showed that there was not adequate support for the original, larger Phase I MST Project described above. As a result, a much smaller project is being considered that would only serve properties in a small area that are willing to pay for the water. This is called the MST Local Project.
This smaller project would include installation of about 3.5 miles of pipeline and one pump station.
Another pipeline option being considered is to add a section of pipeline of the same size along Third Avenue up to approximately Hagen Road.
The EIR/EIS is designed to cover the largest potential recycled water project. However, as mentioned above, local outreach in the MST area has indicated that there is not adequate public support or funding for the larger project. As a result, Napa County is now proposing to build a much smaller Local Project that would serve a limited number of property owners who want the recycled water and are willing to pay for it. Completing the EIR/EIS for the larger project makes it possible to expand the recycled water project in the future. Expansion of the recycled water pipeline will only occur if and when there is future need, public support and funding for it.
