The Nacimiento Water Project (NWP) regional raw water transmission facility that will deliver water from Lake Nacimiento to communities in San Luis Obispo County.  The NWP will include 45 miles of pipeline ranging from 12 inches to 36 inches in diameter, an intake structure at Nacimiento Lake, three pump stations ranging from 1,200 horsepower (hp) to 3,500 hp, and three water storage tanks ranging from 300,000 gallons to 850,000 gallons.  The NWP is designed to deliver 15,750 acre-feet of water per year (AFY).  Atascadero Mutual Water Company (AMWC) has contracted for 2,000 AFY, which will significantly  improve its ability to meet the current and future water needs of its shareholders.  One acre-foot of water is approximately 326,000 gallons. 

The County of San Luis Obispo is the lead agency for the $190 million NWP.  In 2004, AMWC entered into a Delivery Entitlement Contract with the County for participation in the project, with AMWC’s share of the project costs being approximately $39 million to be paid over 30 years.   Other agencies currently participating in the project are the City Paso Robles, Templeton Community Services District, and the City of San Luis Obispo.  The project has already had a large effect on connection fees and water rates paid by AMWC’s shareholders. 

Construction on the project is well underway with completion anticipated as early as July 2010.  According to the County’s project manager, the project is currently under budget.
