Backflow Prevention

North West Utility District’s cross connection and backflow prevention program requires yearly backflow testing within our service area. Backflow testing is required on most commercial water accounts, along with residential irrigation accounts. Inspections must be conducted, annually, by a certified backflow tester, and the information submitted to North West Utility District for review.
