Compliance

Seattle Public Utilities requires that all backflow assemblies be tested annually by a Washington State certified Backflow Assembly Tester (BAT). Test reports must be submitted directly to SPU through their SwiftComply online portal. SPU sends reminder notifications, but the water service owner is responsible for ensuring testing is completed on time. Failure to comply can result in non-compliance charges and potential termination of water service. For full program details, visit the SPU backflow prevention page at seattle.gov.
