A sprinkler system that runs is not the same as a sprinkler system that works. Most of the waste we find is not dramatic leaks — it is misaimed heads, uneven coverage and a controller running a schedule nobody has looked at in years.
Coverage: the fixable problem nobody looks for
Irrigation heads are designed for head-to-head coverage, meaning the spray from each head should reach the next one. Overlap is intentional — a single head does not distribute water evenly across its own radius, so adjacent patterns fill each other's weak zones.
When spacing is wrong or heads have drifted out of adjustment, you get dry rings between heads. The homeowner sees brown patches and responds by increasing run time, which overwaters everywhere else to compensate for a few square feet. That single behaviour accounts for a large share of the waste we encounter.
The diagnostic is simple. Put identical containers around a zone, run it fifteen minutes, and compare how much water each collected. Wide variation means a coverage problem that no amount of extra run time will fix.
Timing and frequency
Run zones between roughly 4 and 9 a.m. Evaporation is at its lowest, wind is minimal, and foliage dries as the sun comes up. Evening watering leaves grass wet overnight, which encourages fungal disease — a real issue in Georgia humidity.
Water deeply and less often rather than briefly every day. Short daily cycles keep moisture in the top inch of soil, and roots stay there because they have no reason to go deeper. A shallow-rooted lawn is far more vulnerable in a dry spell.
For established turf, aim for roughly an inch of water per week including rainfall, delivered across two or three sessions. On Georgia clay, run each zone in shorter cycles with soak time between them — clay absorbs slowly, and a single long run mostly produces runoff down the driveway.
Zoning by plant, not by convenience
Full-sun turf and shaded planting beds have completely different water requirements. When they share a zone, one of them is wrong — usually the beds are getting far more than they need.
Properly zoned systems separate sun turf, shade turf and beds. Planting beds are frequently better served by drip irrigation, which delivers water at the root zone with almost no evaporation loss and keeps foliage dry.
If your existing system has everything on two zones because that was cheapest to install, adding zones is one of the higher-return improvements available.
Smart controllers and rain sensors
A smart controller adjusts run times using local weather data rather than a fixed schedule. It skips cycles after rain, shortens them in mild weather and extends them during heat. Realistic savings are meaningful, and it removes the problem of a system irrigating enthusiastically during a thunderstorm.
A rain sensor is the low-cost version of the same idea and is worth installing regardless. It interrupts the cycle once measurable rainfall is detected.
Whatever you install, check the programming seasonally. A schedule that suits July is roughly double what the lawn needs in April. Most systems we service are running one schedule year-round because nobody changed it.
