Sprinkler repair, irrigation installation and drainage in Fort Worth, Texas — on shallow prairie soils over rock.
Fort Worth is not on blackland clay. Much of the city sits on the Fort Worth Prairie, where the characteristic soil is nine to twenty inches deep over coarsely fractured limestone. That single fact changes everything about an installation here. Trenching means a rock saw rather than a chain trencher, mainline routing gets designed around rock rather than in straight lines, and shallow soil holds very little water — so drought stress arrives far faster than it does on clay, and short frequent cycles beat long ones.
The watering rules here are permanent, not a drought measure. Even-numbered addresses water Wednesdays and Saturdays, odd-numbered Thursdays and Sundays, non-residential Tuesdays and Fridays, and nobody waters on Monday. Nothing runs between 10am and 6pm, year round. Rain and freeze sensors have been required on systems installed since mid-2007. That is a stricter baseline than any city east of Dallas, and it applies whether or not the lakes are full.
Fort Worth also has requirements that a contractor from elsewhere can easily fall foul of. Backflow assemblies must be tested on installation and annually thereafter, by a tester registered with the City of Fort Worth specifically, with results filed through the city’s online system — a tester registered in another city is not automatically accepted here. Controllers must be permanently marked with the irrigator’s licence number and contact details. And the city requires a documented walk-through and a written contract.

Fort Worth has permanent year-round watering rules and, in much of the city, solid limestone within a foot or two of the surface.
Nine to twenty inches to fractured limestone is common. It affects trench depth, mainline routing, how long the work takes and what it costs. We would rather tell you that before we quote than after we start.
Thin soil over rock holds very little water. A schedule copied from a clay-soil lawn will let the turf stress between cycles no matter how many minutes it runs.
Fort Worth requires annual testing by a city-registered tester, filed through the city’s system. An incomplete or missing report causes a failed inspection.
Parts of the system run high enough that the city requires pressure reducing valves on private plumbing above 80 psi. High pressure also misted nozzles and shortens the life of everything downstream.
Fort Worth Water runs the retail system on raw water from the Tarrant Regional Water District. Its twice-weekly watering rules are permanent and year-round, not drought-triggered: even-numbered addresses on Wednesday and Saturday, odd-numbered on Thursday and Sunday, non-residential on Tuesday and Friday, and no watering at all on Mondays. Nothing may run between 10am and 6pm at any time of year. Rain and freeze sensors are required on systems installed since June 2007. Backflow assemblies must be tested on installation and annually, by a tester registered with the City of Fort Worth, with results filed through the city’s online system. Much of the city sits on shallow soil over limestone rather than deep clay.
Under Texas Commission on Environmental Quality rules, selling, designing, installing, altering, repairing or servicing an irrigation system requires a TCEQ licence. Ask any contractor for their license number before work begins — in Fort Worth as anywhere else in Texas.
