Texas Irrigation Code Book
What a Texas city requires of an irrigation system — permit, backflow, sensors, watering days — on top of the state rules that apply everywhere. Check it before you bid, pull the permit, or set the controller.
State rules — these apply on every job in Texas

About this data
How to read it
Every place is marked Full rules, Some rules, No local rules found (we read the city's code and it adds nothing to the state rules) or Couldn't check online (the city doesn't publish its ordinances online, so call them). "Couldn't check" is not the same as "no local rules".
Every rule links to the ordinance or official page it came from, and carries a grade: Verified (filled dot) — read in the code or on the city's own page; Partial (half dot) — official source, a detail still needs confirming; Unverified (open dot) — second-hand only, check it.
Nothing here copies a code book. Each entry summarizes and links so you can read the exact text.

Built and maintained by HindSite Software, makers of FieldCentral — field service software for irrigation contractors. Every irrigator we talk to keeps a version of this in their head. None of them should have to.
