Pearland is the sharpest before-and-after on this list. For most of its history it was a small farming town on the Brazoria County line. From the mid-1990s onward it became one of the fastest-growing cities in Texas, and almost everything that gives this trade work here was built during that growth rather than before it.
Older Pearland — the original town grid and the acreage properties around it — has larger lots, older houses and much lower irrigation penetration. Where systems exist there they were retrofitted, often to part of the property rather than all of it, and often decades ago.
Newer Pearland is a different market entirely. Shadow Creek Ranch, Silverlake, Southdown, Riverstone Ranch and the developments along the Highway 288 corridor were laid out as master-planned communities with irrigation as standard equipment, deed restrictions that expect a maintained lawn, and lot sizes that support six to ten zones. That is where the systems are.
Pearland sits across three counties — mostly Brazoria, with parts in Harris and Fort Bend — and this matters more than it sounds. It means different appraisal districts, different county-level arrangements and, most relevantly, a genuinely mixed picture of who supplies the water. Some of the city is on the City of Pearland utility. Substantial parts of the newer development are inside municipal utility districts. Shadow Creek Ranch in particular spans jurisdictional lines in a way that makes any general statement about rules unreliable.
The practical version is the same as everywhere in this metro: find the provider on the water bill. It is the one that sets the drought stage and decides whether an annual backflow test is required, and in Pearland it is unusually likely not to be the city whose name is on the address.
Pearland is flat, low and has been the subject of extensive drainage work as it has grown. Two consequences for irrigation, both of them practical rather than dramatic.
Detention areas and drainage reserves back onto a great many lots here, and the zone that serves that boundary is the one that gets forgotten and the one most likely to be watering a slope into a ditch. And regraded ground, whether from municipal drainage work or from a lot that was built up during construction, settles for years afterwards — which pulls heads out of grade and puts shallow laterals under strain long after the builder has gone.
Shadow Creek Ranch began around the turn of the millennium, and the first phases of the Highway 288 corridor developments are now well into their twenties. That is the point at which solenoids, controllers, rain sensors and backflow assemblies all start reaching end of life together, because they all went in on the same day. A cluster of unrelated-looking failures on a system of that age is not a coincidence and does not usually mean the system is finished — it means the accessible components are due.
Probably not. On a system where everything was installed at once, the components with similar service lives reach the end of them at similar times, so a run of unrelated failures around the twenty-year mark is normal rather than terminal. The buried pipe, which is the expensive part to replace, is generally the part with the most life left.
Two things. The perimeter zone is watering ground that slopes away from the property, so a good part of what it applies is leaving. And boundary heads are the ones nobody inspects, so faults there run for months. It is worth walking that zone specifically rather than assuming the schedule covers it.
Both, depending on the address, and that is a genuine answer rather than a hedge — the city grew by annexing and by development inside utility districts, so the picture is mixed. Check the provider named on the water bill; it is the authority on drought stages and backflow testing regardless of what the postal address says.
What to expect from a system where everything is the same age.
Turn-of-the-millennium timers still running the schedule.
Settled fill, regraded lots and coverage that drifted.
The assemblies here are the same age and the same exposure.
Subdivision and roughly when the house was built. In Pearland those two answers separate two completely different kinds of system.
