The purpose of cross connection control and backflow prevention is to ensure that all drinking water systems remain clean and safe for public use. Federal, state and local codes require public water systems to:

  • Conduct customer service inspections on private plumbing systems
  • Require backflow protection using appropriate backflow assemblies
  • Require those assemblies be tested to ensure they are working correctly

By City Ordinance Number 53.003 (Cross Connection and Backflow Prevention) some property owners in Pflugerville are required to install and maintain backflow prevention devices and perform annual tests on them as proof of compliance.

What is Backflow?

Backflow is the undesirable reversal of the flow of water from its intended direction in a pipeline or plumbing system. Backflow can occur when pressure is reduced in the distribution system due to a break in the main line, firefighting, or other distribution system situations. Backflow can allow contaminants to enter private plumbing systems and city water distribution systems.

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).

Potable vs. Non-Potable

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 did not go through the same treatment process as potable water.

Do I have a backflow prevention device?

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 512-990-6400.

I received a backflow Device Notice.

 If you received a notice, you will need to do the following:

  1. Hire a Registered Backflow Tester
  2. Provide your Customer Confirmation Number (CCN), located on the notice, to your Tester
  3. Check your test report status using your CCN at BSIOnlineTracking.com

 

The backflow tester will need to:

  1. Perform the required test
  2. Submit all test reports through BSIOnlineTracking.com
  3. Pay $12.95 per test report submitted.

Why do I need to have my device tested?

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 is necessary to ensure the device is working properly. Depending on the degree of hazard, high health hazard backflow prevention devices need to be tested annually.

  • Annual Testing is required for High Health 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.
