Backflow enforcement and delinquent fees will resume beginning Aug. 1.
Backflow prevention is essential for protecting our drinking water from the dangers of backflow. Backflow Solutions, Inc. (BSI Online) administers our Backflow Prevention Program, ensuring backflow prevention devices are installed and maintained in compliance with federal, state, and local codes.
Backflow is the reverse flow of water in any pipeline, 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 waterline breaks, the water pressure in the pipe on the City’s side 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.
Backflow prevention devices are used to protect our potable water supply from contamination due to backflow. 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 devices are required for plumbing system connections that contain chemicals or industrial fluids, irrigation systems, fertilizers, or auxiliary water sources (including reclaimed water).
Residential properties with irrigation systems, pools, or fire sprinkler systems are required to have a backflow prevention device. These devices are typically located by the curb in a separate box by your water meter box.
For help determining if you have a backflow device, please contact Backflow Prevention at 512-218-5575.
The City sends notifications, through BSI Online, to residents and businesses 30 days prior to their testing due date.
- Hire a Registered Backflow Tester.
- Provide your Customer Confirmation Number (CCN), located on the notice, to your Tester.
- Check your test report status using your CCN at BSIOnlineTracking.com.
- Perform the required test.
- Submit all test reports through BSIOnlineTracking.com.
- Pay $12.95 per test report submitted.
Backflow prevention devices are mechanical devices containing springs and other moving parts that are subject to wearing down and/or breaking. Routine maintenance and testing are necessary to ensure the device is working appropriately. Depending on the degree of hazard, backflow prevention devices need to be tested either annually or once every 7 years.
- Annual Testing is required for High Hazard devices. These devices are typically used for non-residential purposes, such as hospitals, restaurants, industries, etc. in which there is a high risk of contamination. Residential pools with auto-fill are also required to have a high hazard device and have it tested annually.
- 7 Year Testing is required for Low Hazard devices. These devices are typically used for residential purposes, such as irrigation systems. The risk of contamination is much lower than those considered high hazard; therefore, testing is only required once every 7 years.
If the backflow device is not tested within the allotted time frame, the City will have the device tested and a testing fee of $75 plus the actual cost of each test will be charged to your water bill.
If you had your device tested and it did not pass, you will have 30 days to have the device repaired and retested.
If the City had your device tested and it did not pass, the actual cost of the repairs and the retest will be added to your water bill.
Texas Commission on Environmental Quality, Chapter 290 – Public Drinking Water Regulations
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, gasses, pollution, infective agents, or any other contaminant.
|All test reports for existing and replacement backflow devices must be submitted through BSI Online. All backflow testers must register on BSI Online in order to submit reports. A fee of $12.95 is charged for each report submitted. This does not apply to new installations.|
In order to become an approved backflow prevention assembly tester within the City, you must provide to BSI Online proof of commission licensing, and proof that your testing equipment is able to maintain a calibration of plus or minus 0.2 psid accuracy.
- Backflow Prevention Assembly Tester (BPAT) license and gauge calibration certification must be submitted and maintained before any backflow test reports will be entered into the system. Information can be submitted via mail, fax, or email.
- Reports will be rejected if the updated license and gauge information are not on file and available upon request of City Backflow Official.
- Annual Testing is required for High Hazard devices. Devices typically used for non-residential purposes, such as hospitals, restaurants, industries, etc. in which there is a high risk of contamination from backflow into the water system. Residential pools with auto-fill are also required to have a high hazard device and have it tested annually.
- 7 Year Testing is required for Low Hazard devices. Devices typically used for residential purposes, such as irrigation systems. The risk for contamination is much lower than those considered High Hazard; therefore testing is required once every 7 years.
Failure to complete the required testing – If the property owner and/or person in control of the backflow device fails to have the device tested within the allotted time frame, the City will have the device tested and a testing fee of $75 plus the actual cost of each test will be applied to the owner’s water bill.
Test failure – If the device is tested and does not pass, the property owner will have 30 days to have the device repaired and retested. If the City had the device tested and it did not pass, the actual cost of the repairs and the retest will be applied to the owner’s water bill.
