Sprinkler repair, irrigation installation and drainage in Denton, Texas — on Cross Timbers sand rather than blackland clay.
Denton sits in the Eastern Cross Timbers, and the city says so in its own words: sandy or sandy loam soils derived from sandstone, which drain well. That is the opposite of the blackland clay twenty miles east. Clay’s problem is that water runs off before it soaks in. Sand’s problem is that water keeps going straight past the roots. The fix is the reverse too — shorter, more frequent cycles rather than long soaks with gaps between them.
It changes the failure modes as well. You do not get much of the seasonal heave that tilts heads and shears laterals on clay. What you do get is trench settlement, and systems that look fine while quietly delivering water below the root zone. A lawn that browns despite a controller running plenty of minutes is a very different diagnosis here than it would be in Rockwall.
Denton runs its own water utility on Lake Lewisville and Lake Ray Roberts rather than buying from a regional district, so its rules are its own and can move independently of everyone else’s. There is a standing summer prohibition on lawn watering between 10am and 6pm, and the city can move into drought stages with assigned days at short notice. Check the city’s page rather than assuming — this is one of the more changeable places we work.

Denton is sandy, not clay. Almost everything we tell homeowners east of Dallas about watering is wrong here, and in the opposite direction.
Long soak cycles push water straight through sand and past the roots. Splitting the same total minutes into shorter, more frequent runs keeps it where the grass can use it, and usually reduces the total.
Sandy backfill settles. Heads sink below grade and lines sag, which shows up as poor coverage rather than a dramatic break.
With two universities in town a large share of housing is rented. Systems get neglected between tenancies, and the first anyone notices is a bill or a soaked patch.
Denton runs its own supply and can move into a stage on its own timetable. A controller programmed last spring may be on days the city no longer allows.
Denton runs its own water utility, drawing from Lake Lewisville and Lake Ray Roberts rather than buying from a regional district — so its rules move independently of the cities east of Dallas. There is a standing prohibition on lawn watering between 10am and 6pm from 1 June to 30 September, and the city can enter drought stages that assign watering days by address at short notice. Foundation watering by soaker hose is treated separately from irrigation. Irrigation work requires a city permit and passes two inspections. Check the city page for the current stage before reprogramming anything.
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 Denton as anywhere else in Texas.
