Backflow Prevention

Every day we rely on water, it is our lifeline.  It keeps our lives healthy and sanitary.  When we use water from our faucets, we assume and expect it will be free from contamination.  Lafayette Utilities System Cross-Connection Control and Backflow Prevention Program is to prevent contaminated water or other unapproved substances from entering the public water system.

Protecting the Water Supply is Everyone's Responsibility
Louisiana State Plumbing Code Section 609
Protection of Potable Water Supply

What is Backflow?

The American Water Works Association (AWWA) defines backflow as the undesirable reversal of flow of fluids, gases or other substances into a potable water distribution piping system as a result of a cross-connection.

What is a Cross-Connection?

Cross-Connections are defined as actual or potential connection between a potable water supply and a non-potable source.  The connection could allow contaminates or pollutants to enter the drinking water supply.

Lafayette Consolidated Government has enacted Ordinance O-253-2012 requiring the elimination or the installation of approved backflow prevention assemblies for the control of cross-connections. View the Policy and Procedures document for more details.

Required Annual Testing of Backflow Prevention Assemblies

While backflow prevention assemblies do a good job at protecting the water supply, they must be tested and maintained regularly to make sure they are in proper working order.  Since they are mechanical they have springs, seats, rubber seals and moving parts that wear out overtime. Lafayette Utilities System requires backflow prevention assemblies to be tested on an annual basis.

Tester Information

There are two types of testers: General Testers and Water Supply Protection Specialist (WSPS) Testers. General testers are only allowed to test backflow prevention assemblies. General testers cannot install or perform maintenance on backflow assemblies.  WSPS testers are licensed journeyman or master plumbers, and Horticulture Commission of Louisiana- licensed landscape irrigation contractors (irrigation contractors are only to test, install and maintain backflow assemblies on landscape irrigation systems.)  WSPS plumbers can test, install and maintain any backflow prevention assembly.

Due to the fact that test prices vary among testers, you may want to contact several certified testers to obtain quotes for your test.
