Sprinkler Systems Built for Florida's Watering Rules and Sandy Soil
$2,500 to $6,000 for a complete residential system. Every installation includes a rain sensor, backflow preventer, and SWFWMD-compliant controller programming. Custom zones matched to your turf, beds, and sun exposure.
Hand Watering Cannot Keep a St. Petersburg Lawn Alive
Florida's sandy soil drains fast. Pinellas County's average summer temperature sits above 90 degrees. Between the heat, the drainage, and SWFWMD's twice-per-week watering restrictions, a lawn without an irrigation system is fighting a losing battle from April through October.
A properly designed sprinkler system delivers the right amount of water to the right zones at the right time. Turf areas get rotary nozzle coverage that applies water slowly enough for sandy soil to absorb it. Planting beds get drip lines that target root zones without wetting foliage. Shady zones get less water than full-sun zones. The controller runs at 4 AM when evaporation is lowest and wind is calmest.
The result: a lawn that stays green through summer on two watering days per week, compliant with every SWFWMD regulation, using 30 to 40 percent less water than a typical spray-head system designed in the 1990s.
Zone-by-Zone Engineering -- Not a Generic Layout
Every sprinkler system we install starts with a site survey. We measure the yard, note sun and shade patterns, identify turf versus beds versus hardscape, check water pressure at the meter, and calculate how many heads each zone can support at full pressure.
Generic sprinkler layouts waste water because they treat the entire yard the same. Your sod lawn in full sun needs different coverage than the shaded bed under the oak tree. The narrow side yard needs different heads than the open backyard. The landscape beds along the house need drip, not spray.
We separate these into independent zones, each with its own valve and runtime. The controller runs each zone for the duration that zone needs, not a blanket 20 minutes across the whole yard. This precision is what keeps your water bill reasonable while keeping everything alive.
- Rotary nozzles for turf -- 0.5 in/hr application rate matches sandy soil absorption
- Drip irrigation for beds -- targets roots, eliminates foliage wetting and fungal problems
- Rain sensor mandatory -- shuts system off when it rains, required by SWFWMD
- Smart controller optional -- adjusts runtimes based on weather data automatically
Every Sprinkler Installation Includes These Components
Backflow Preventer
Required by Florida plumbing code to prevent irrigation water from contaminating the potable supply. We install a double-check valve or reduced-pressure zone device depending on your municipality's requirements. This is not optional -- it is the law.
Zone Valves and Boxes
Each zone gets an electric valve housed in a ground-level valve box for easy maintenance access. We use commercial-grade valves rated for Florida's mineral-heavy water. Valve boxes are installed at grade so they do not interfere with mowing or create trip hazards.
Controller and Rain Sensor
A programmable controller mounts in your garage or under a covered area. Standard models handle 6 to 12 zones with multiple program start times. We program your two designated watering days and set zone runtimes based on our precipitation-rate calculations. The rain sensor interrupts the cycle when rainfall exceeds a set threshold.
Mainline and Lateral Pipe
Schedule 40 PVC mainline from meter to valves. Class 200 PVC lateral lines from valves to heads. All connections are solvent-welded, not push-fit. We pressure-test the entire system before backfilling trenches to catch leaks when they are cheap to fix.
Sprinkler Heads
Rotary nozzles on pop-up bodies for turf zones. Drip emitters on polyethylene tubing for beds. Heads are spaced for head-to-head coverage, meaning every point in the zone is reached by at least two heads. This eliminates dry spots that show up as brown patches two weeks after install.
System Testing and Walkthrough
After installation, we run every zone while you watch. We adjust head positions, check for overspray onto hardscape, verify coverage uniformity, and confirm the controller schedule matches your designated watering days. You get a zone map and operating instructions before we leave.
Shore Acres Install: 6 Zones, 4,200 Sqft Lawn, $3,800
A Shore Acres homeowner had been hand-watering a new Zoysia sod installation for three weeks and watching it brown despite daily effort. The problem was coverage. Hand watering cannot deliver the uniform half-inch of water that Zoysia needs, and the effort of dragging a hose meant the back corners always got shorted.
We installed a 6-zone system: four rotary-nozzle zones covering the front, back, and side turf areas, one drip zone for the foundation beds, and one drip zone for the backyard planting island. Total cost including permit, backflow preventer, Hunter Pro-HC controller, and wireless rain sensor: $3,800.
The sod recovered within two weeks of consistent automated watering. Their water bill actually dropped $15 per month compared to the hose-watering period because the system applies water at the right rate during the right hours with zero runoff waste.

$2,500 to $6,000 for a complete residential system. Small lots (under 3,000 sqft) with 3-4 zones run $2,500-$3,500. Average lots with 5-7 zones cost $3,500-$5,000. Price includes trenching, pipe, heads, valves, controller, rain sensor, and backflow preventer.
2 to 4 days for most residential systems. Small 3-4 zone systems complete in 2 days. Larger 6-8 zone systems take 3-4 days. Includes trenching, pipe, heads, controller setup, and full system testing.
Yes. Pinellas County requires an irrigation permit for new installations. The permit ensures SWFWMD compliance, proper backflow prevention, and rain sensor inclusion. We handle all permit applications.
SWFWMD allows irrigation twice per week on designated days based on your address (odd/even). Watering is prohibited between 8 AM and 6 PM. A rain sensor or soil moisture sensor is mandatory. We program your controller to comply with all current rules.
Rotary nozzles at 0.5 in/hr application rate. They match sandy soil absorption, reduce runoff, and provide uniform coverage. Traditional spray heads at 1.5 in/hr overwhelm sandy soil and waste water to runoff. We use drip irrigation for beds.
