MMWD narrows Sonoma-to-Marin pipeline options
Aiming to boost the county’s water supply, the Marin Municipal Water District is exploring the idea of connecting pipelines in Petaluma and Cotati to its reservoirs. District staff presented three main potential projects — narrowed from 13 — at Tuesday’s board of directors meeting. … The pipelines would transport water from the Russian River into Marin reservoirs. Treated Russian River water is transported to Marin through a 9-mile aqueduct along the Highway 101 corridor from Petaluma to North Marin Water District in Novato. The district then sends the water directly to the Marin Municipal Water District’s water distribution system. Board members expressed concern over cost estimates, which ranged between $140 million and $380 million.
