Templates for Public Notification
The State of California's drinking water regulations require public notification under certain circumstances. Water systems must contact the Division of Drinking Water's (DDW's) district office if public notification is required. Any notification must be approved by DDW prior to distribution or posting, unless otherwise directed by DDW.
The following templates can be used by public water systems to prepare notices for their customers and consumers.
