The State Board proposes to amend California Code of Regulations, Title 22, Division 4,
Chapters 3 and 17, for the purpose of establishing regulations governing the planned
placement of recycled water into a surface water reservoir that is used as a source of
domestic drinking water supply; a process known as surface water augmentation
The adoption of “Surface Water Augmentation Using Recycled Water” regulations will:
Amend Article 1, Chapter 3, to amend an existing definition and establish definitions related to SWA.
Adopt Article 5.3, Chapter 3, Division 4, to establish criteria applying to water recycling agencies that may choose to engage in SWA with a public water system (PWS).
Adopt Article 9, Chapter 17, Division 4, establishing criteria for a PWS that may choose to utilize a reservoir augmented with recycled water.
The regulations were initially released for a 45-day comment period that ended on September 12, 2017. The State Water Resources Control Board has since changed the text of the proposed regulations regarding Surface Water Augmentation, and is accepting written public comments for the changed text. The 15-day public comment period ends on December 18, 2017, at 12:00 P.M. (noon).
