COVID-19 SWRCB NOTIFICATION - PUBLIC WATER SYSTEMS
What is a small water system?
A small water system is defined as water for human consumption that has 15 or more service connections or regularly served at least 25 individuals at least 60 days out of the year. Nevada County through our Local Primacy Agency, under contract with the State Water Resources Control Board, ensures that small water systems deliver safe, adequate, and dependable potable water.
Water systems are divided into the following categories:
- Community Water System: A public water system that has 15 or more service connections used by year-long residents OR regularly serves at least 25 year-long residents of the area served by the system.
- NonTransient-Noncommunity Water System: A public water system that is not a community water system that regularly serves at least 25 of the same persons during six months of the year.
- Transient-Noncommunity Water System: A non-community water system that does NOT regularly serve at least 25 of the same persons during six months of the year.
- State Small Water System: A system for the provision of piped water to the public for human consumption that serves at least five, but not more than 14, service connections and does not regularly serve drinking water to more than an average of 25 individuals daily for more than 60 days out of the year.
