Small Water Suppliers Reminded to Submit Water Production Data

Small water suppliers in California must report potable water production data to the state by Dec. 15. The data must include November numbers.

The State Water Resource Control Board’s Office of Research, Planning & Performance sent out a message to all small suppliers who submitted a drought report last year or are a point-of-contact for a small supplier system in its Safe Drinking Water Information System (SDWIS) Data.  The notice advises small suppliers of the requirement to report potable water production and respond to a few questions.  The requirement is encompassed in the State Water Board’s emergency conservation regulation, which can be viewed HERE(see Section 864.5(g)). 

The online form needs to include data from November 2016 so it should not be submitted until December 2016.  If you have questions, you may direct them to Kathy Frevert at call (916) 322-5274.

Small water suppliers are defined as any supplier that is not an urban water supplier.  For practical purposes, a small water supplier that needs to submit a report is any public community water system that is not classified as an urban water supplier and provides water for human consumption to between 15 and 3,000 service connections or serves at least 25 individuals year round.   

Suppliers that are unsure if they should submit a report may check the Small Supplier Reporting Decision Tree. The web-based reporting form for small water conservation reports is here. Suppliers should not report until they have data for November 2016:  

  • The required information includes:
  • Total potable water production by month for January through December 2013 (calendar year).
  • Total potable water production by month for December 2015 through November 2016 (12 months starting with December 2015); and
  • Any actions taken by the supplier to encourage or require its customers to conserve water.
