Marin Municipal Water District to Replace Pipeline in Tamalpais Valley

This month MMWD will begin construction on the Alta Vista Road Pipeline Replacement Project which will install 840 feet of 6-inch welded steel pipe and 130 feet of 2-inch copper pipe, with valves, fitting and appurtenances. Construction is scheduled to last through July 2017. The installation will replace old, undersized pipe installed in 1942 in coordination with the neighborhood HOA overlay project in the Tamalpais Valley. This project aligns with MMWD’s five-year strategic plan to improve water supply resiliency and maintain facilities and equipment sufficiently.

On March 21, 2017, the District received and opened six bids for the subject contract. The lowest responsible bid was submitted by D&D Pipelines Inc. in the amount of $167,438. The contractor, D&D Pipelines Inc., and MMWD will make every effort to minimize traffic disruptions during construction.

Customers with questions about the project can contact MMWD Design & Engineering Manager Jeff Ohmart at 415-945-1574 or

MMWD is Marin County’s largest provider of drinking water, serving a population of 187,500 in a 147-square-mile area of south and central Marin County. The district owns and manages 21,600 acres of watershed land on Mt. Tamalpais and in west Marin. The primary source of water supply is rainfall captured in seven reservoirs, providing 75 percent of the water consumed each year. The remaining 25 percent is imported annually from the Russian River through an agreement with the Sonoma County Water Agency. MMWD also operates its own recycled water system. District operations are financed primarily by revenue from the sale of water.
