The majority of Napa Valley's communities require water storage tank regulations in order to operate their local water utilities. Typically, water storage tanks are sized large enough for your home's irrigation and general use as well as at least a 2 week supply of municipal water. Napa County also requires residential homes to have at least 2500 gallons of independent fire water storage for rural areas not accessible by a municipal fire hydrant.
Napa County's two primary water storage facilities are located at the historic Old Orchard Road Waterworks Park on the west end of Old Orchard Road and the newly established City of Napa Creek at the foot of Old Napa Creek. Both of these facilities require both an on-site inspection by a licensed engineer and an annual inspection by an independent certified contractor. Both facilities offer the services of fully bonded professional engineers who are insured against any loss or damage to property or water supplies.
Most water providers in the Napa Valley are members of the American Water Works Association (AWWA), which is the main regulatory agency for the country's water supplies. AWWA has adopted national standards that apply to all water providers. These national standards include water quality assessment, water flow rate, water pressure, treatment methods, storage capacity, storage tanks, and waste water disposal.
Napa Valley's water providers must adhere to AWWA's local regulations, which vary from area to area. Some cities, such as Napa, have local ordinances in place that require certain minimum amounts of storage for residential uses while other cities do not have such ordinances. In addition to local ordinances, Napa County has a statewide mandate that applies to all of its water users. All of Napa's water providers are required to test the storage levels of their water facilities at least once a year and if found to be above the mandated amount the provider must either dispose of the water or sell it to a recycling company. Failure to comply with this mandate can result in fines and other penalties.
Napa County's two public water treatment facilities, the John Day River Water Facility and the Crooked Rock Municipal Water Treatment Facility, also have mandatory storage requirements. The Crooked Rock facility tests the water in its storage tanks for bacteria and other microorganisms at a frequency of twice per day, while the John Day facility conducts weekly water testing of its tanks. Both facilities maintain separate levels of safe and unsafe levels of bacteria, sediment, chemicals, pesticides, herbicides, minerals, and other contaminants in the storage tanks.
The Napa County Department of Health and Human Services (HHS) regulates the water supplies in the area through an Environmental Quality Assurance Program (EQAP). The program is designed to monitor water quality throughout the County. To ensure compliance with this program, an independent certified environmental engineer performs an annual review of the water quality in the area as well as samples of water collected at various points throughout the County. Once the quality review is complete the county department publishes an annual report that contains information about the findings of the report, recommendations made, and any actions taken to correct any identified problems.
