GPS Locations

The Utility is in the process of re-surveying all of our service protection backflow prevention assemblies. During this process we are gathering GPS location data for each assembly. As we collect the data, we are updating test notifications to include driving directions and GPS data to assist you in locating the correct backflow prevention assembly. 

Test Forms

  • Test forms are available at the Utility’s main office located at 11000 N. La Cañada Drive or the Backflow Department located at 12947 Pusch Mountain View Lane. 
  • In addition, there is a printable and electronic test form available on the Town of Oro Valley’s website in the Backflow Prevention section. Backflow Prevention Assembly Test Form(PDF, 144KB)
  • Completed test forms must be emailed to , faxed (520-229-5029) or delivered to the Utility prior to the compliance date on the customer’s test notice.

Description of the Utility’s Test Notification Process

As you know, the State Drinking Water Rule requires backflow prevention assemblies to be tested at least annually. The Utility monitors the testing of more than 1600 assemblies. The Utility must receive a test form by the 20th of the month in which the test is due.

Each month, a 45 day test notification is sent to customers that are due in the following month. If we do not receive a test form within 15 days of the compliance date, a second notice is sent by certified mail to the customer. The customer is contacted by phone to make sure the Utility has contacted the correct individual, and that they understand the testing requirements and the compliance deadline. If the Utility does not receive a test form by the 20th, then the customer has not complied with the testing requirement.

On the 21st, irrigation services are turned off and locked. There will be an $80.00 reconnect fee charged to these customers. Noncompliance domestic water services and fire lines will receive a “hand carried” 4-day notice. At the discretion and option of the Water Quality/Backflow department, the Utility has the option to be on site to test the backflow prevention assembly. The customer will be charged a testing fee of $50.00. Fees will also be charged for employee’s time and if needed, repair parts. A fine of $100.00 for noncompliance and failure to comply for two consecutive years will result in a fine of $250.00.

In order for the Utility to remain in compliance with State regulations, it is important that we receive a completed test form by the compliance date. The Utility will accept a failed test form. The repair must be made within a logical amount of time.

Tester’s Contact Information

The Utility must maintain a record of each Tester’s certification and gauge calibration. As you know, your Backflow Prevention Tester Certification expires every three years and your test gauge calibration expires every year. The Utility will not accept a test form unless we have a current copy of your certification and calibration. Please update the Utility with your certification and gauge calibration renewals.

If there is a change in your contact information, please let us know. There are situations when we need to contact you.

  • Meter remains locked off until compliance is achieved with backflow prevention requirements.
  • The backflow prevention assembly is installed by the contractor to Utility’s specifications.
  • Contractor schedules a testing firm to test the backflow prevention assembly. The water meter must be unlocked by the Utility for this test.

 Backflow Prevention on Fire lines

The Utility requires the installation of a double check backflow prevention assembly on all new commercial fire lines. If the fire system requires the use of chemicals or an auxiliary water supply, then a reduce pressure backflow prevention assembly is required. A permit and test is required for a fire line backflow prevention assembly.
