Amount of water produced by month and by source and the water delivered by type of use and by month for every Public Water System (PWS) reporting. Public Water Systems submit their annual inventory information using the electronic Annual Report (eAR) submission process. The electronic Annual Report (eAR) is a survey of public water systems, currently required annually, to collect critical water system information intended to assess the status of compliance with specific regulatory requirements such as source water capacity, provides updated contact and inventory information (such as population and number of service connections). The specific dataset is section 6 of the eAR for the years 2013-2022 (both included) that collects the water produced by month and by source and the water delivered by type of use and by month for every water system reporting. It also includes facility public information details from the SDWIS database as metadata associated to the dataset. More information about the eAR required reporting here: https://www.waterboards.ca.gov/drinking_water/certlic/drinkingwater/ear.html . A "Public Water System" means a system for the provision of water for human consumption through pipes or other constructed conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year.
