If you had your assembly tested and it did not pass, you will have 30 days to have the assembly repaired and retested.

Backflow is the reverse flow of water, causing non-potable water to flow into the public water supply. Backflow can occur when changes in water pressure create a suction effect, forcing non-potable water into the City’s drinking water supply. For example, when a main water line breaks, the water pressure in the pipe is drastically reduced. The reduced pressure causes a suction effect and any substance in the pipe on the customer’s side is then drawn up into the system, contaminating the City’s water supply.
Potable water is safe for consumption. This water has been properly treated so that it is safe for drinking, bathing, and cooking.
Non-potable water is NOT safe for consumption. This is water that either did not go through the same treatment process as potable water or it has been properly treated but has since become contaminated. Many factors can make potable water become non-potable, such as exposure to chemicals, gases, pollution, infective agents, or any other contaminant.
Backflow prevention assemblies or an air gap can be used to prevent backflow into potable water systems.
Without these barriers, water that is no longer safe for consumption, such as water from pools, irrigation systems, restaurants, and medical facilities, could travel into the City’s water supply and contaminate the drinking water.
Typically, backflow prevention assemblies are required for plumbing system connections that contain chemicals or industrial fluids, irrigation systems, fertilizers, or auxiliary water sources (including reclaimed water).
If you received a notice, you will need to:
The backflow tester will need to:
The City of Boerne requires all Backflow Prevention Assembly Testers (BPATs) to register with the City before testing any backflow assemblies within the City. Per City of Boerne Ordinance No. 2022-22, BPATs must register annually, provide proof of TCEQ certification, provide proof that testing equipment is able to maintain a calibration of plus or minus 0.2 psid accuracy, and pay an annual, non-refundable tester registration fee of $50.
Upon registration and verification of license and gauge calibration, and test for accuracy reports, the tester will be added to the approved list of Backflow Prevention Assembly Testers.
Testers must submit test reports directly to the City of Boerne located at 447 N. Main St., Boerne, TX, 78006.
