Sprinkler Repair in the Memorial Villages

The Memorial villages — Bunker Hill, Piney Point, Hedwig, Hunters Creek, Hilshire and Spring Valley — are separate incorporated cities surrounded by Houston, and they are the highest-value irrigation territory in the metro by some distance. Large wooded lots, extensive planted beds and a landscape standard that is enforced socially rather than by covenant produce systems with zone counts most of this metro never sees.

Trees Are the Defining Local Problem

Nothing else on this site has quite this issue. The villages kept their canopy — large, old live oaks and pines over most properties — and mature trees do three things to an irrigation system, all of them slow and all of them expensive.

They lift and displace buried pipe. Root growth over a decade will move a lateral out of line, crack a solvent-welded joint, or wrap a pipe closely enough that any future repair means working around roots that cannot simply be cut. They shade turf, so a zone under a canopy needs a completely different run time from the same zone twenty feet out in the open — and if both are on one valve, one of them is always wrong. And they drop enough leaf litter to bury heads and block nozzles year-round rather than seasonally.

The design answer is more zones rather than longer run times: separating shaded turf from open turf, and separating bed drip from either. That is why properties here run zone counts in the teens, and why a system that was adequate when the trees were smaller stops being adequate without anything having broken.

Second and Third Generation Systems

Many of these properties have had irrigation for decades, added to and rebuilt in stages. What that produces is a system with no single design: original mainline in one part of the yard, a 1990s extension in another, a zone added when a pool went in, and a controller replaced twice with the field wires reconnected each time by somebody who did not have the original schedule. Tracing what is connected to what is a real part of any first visit here, and it is why an audit is worth more on these properties than on a subdivision lot where everything went in on one day.

Water Supply

The villages are not on a single system. Bunker Hill, Hunters Creek and Piney Point are served by the Memorial Villages Water Authority; other villages have their own arrangements. As everywhere in this metro, the provider named on the bill is the authority on drought stages and on whether an annual backflow test is required — and on properties with the zone counts common here, the assemblies are frequently larger than the residential standard, which changes both the testing question and the replacement cost.
