Deer Trail Water District is a public water system in Texas. Backflow preventer assemblies on its distribution system must be tested by a certified tester and the test report filed with the purveyor — here is how filing works.
Deer Trail Water District takes backflow test submissions through EnviroTrax (Vepo LLC). Testers enter each test in the portal themselves — no bulk upload exists for any portal vendor — so BackflowGo preps your re-key sheet (every value in the portal's entry order) and routes you to EnviroTrax (Vepo LLC) to file.
Texas requires TCEQ Form 20700 — BackflowGo fills the official PDF for you.
Listing data is sourced from the EPA SDWIS federal registry and BackflowGo's own purveyor research. All Texas water systems →
