Cross Connection Requirements
The state water regulatory agency, Texas Commission on Environmental
Quality (TCEQ), sets the rules for WCID17. You can find a complete set of these
rules in the Rules and Regulations for Public Water Systems 30TAC chapter 290
subchapter D.
All backflow prevention assemblies (BFPs) must be tested
upon installation and certified to be operating within specifications. Backflow
prevention assemblies which are installed to provide protection against health
hazards must also be tested and certified to be operating within specifications
at least annually by a recognized backflow prevention assembly tester.
A Test Report must be completed by the recognized backflow prevention assembly tester for
each assembly tested. The signed and dated original must be submitted to the District for record keeping purposes.
At any residence or establishment where an actual or potential contamination hazard exists and
the District has properly inspected the residence, backflow protection at the water service entrance or meter is
not required.
The use of a backflow prevention assembly at the service connection is considered as additional
backflow protection. The use of backflow protection on internal hazards as required by local plumbing codes will be
enforced.
Backflow prevention assembly testers must be qualified to test and repair assemblies on any
domestic, commercial, industrial or irrigation service.
Backflow prevention assembly testers may test and repair
assemblies on firelines only if they are permanently employed by an approved
fireline contractor. The State Fire Marshall's office requires that any person
performing maintenance on firelines must be employed by an approved fireline
contractor.
If your system has a high hazard BFP installed for health
hazard protection, the District will mail a letter annually listing the devices
that must be tested. You will have 30 days to get the BFP tested and repaired
(if needed) and test results faxed to our office at (512) 266-2790. A list of
certified testers will be included for you convenience.
