ABOUT PASO ROBLES WATER

Water Sources

This slide presentation briefly explains the community water situation and the solution that is Nacimiento Water – for your information and reference. [pdf:2.1mb/7pp]

The City of Paso Robles uses groundwater only, drawn from a large aquifer known as the Paso Robles Basin and the Salinas River Underflow. Four of the river wells, known as the Thunderbird Wells, are located on Ramada Drive, and the fifth, known as the Borcherdt Well, is on South River Road. The remaining nine wells draw from the groundwater basin and are located on the east side of town as follows:

Sherwood 9 Well at Sherwood Park
Sherwood 11 Well on Linne Road
Butterfield 12 Well on Golden Hill Road
Osborne 14 Well on Cottonwood Drive
Avery Well and Dry Creek 18 Well on Airport Road
Tarr 19 Well on Aerotech Way
Royal Oak 20 Well on Airport Road
Fox 21 Well on Dry Creek Road and
Cuesta 22 Well on Buena Vista.

The 2005 Urban Water Management Plan (completed in April 2008) documents the City’s sources of water supply, defines water demands, presents a water shortage contingency plan, describes implementation of water demand management measures and guides conservation efforts. Learn more...

Monitoring System

The City uses a central computer to monitor and control the wells, booster pumps and reservoirs. This system is called SCADA (Supervisory Control and Data Acquisition). The system allows monitoring of all water wells (running or idle), reservoir levels, and booster pump discharge pressures.

Water Quality

Over the years, the City has dedicated itself to producing drinking water that meets or exceeds all state and federal drinking water standards. You can download the entire Water Quality Report here or pick one up at Water Services in City Hall at 1000 Spring Street.

Testing

The City’s water is regulated by numerous agencies under many laws. Some of the agencies that monitor are:

To comply with regulations, the water wells and locations throughout the City are tested regularly. The samples are sent out to an independent laboratory to be tested, insuring compliance with all state and federal regulations. On a weekly basis the system is tested for coliform bacteria as an early indicator for pathogenic contamination in the water.
