Build a sprinkler system that protects your landscape and respects local watering rules
In San Antonio and the surrounding Hill Country, a “good” irrigation system isn’t the one that waters the most—it’s the one that applies the right amount, in the right places, at the right times. This guide breaks down what matters most in a professional sprinkler system installation: efficient layout, matched equipment, smart control, drainage awareness, and the compliance items homeowners and property managers often miss.
What “done right” looks like for irrigation in San Antonio
A dependable sprinkler system is engineered around your site conditions: soil type, slope, sun exposure, plant types (turf vs. beds), and water pressure/flow. When those inputs are ignored, the system may “work,” but it tends to create the same headaches—runoff onto sidewalks, dry patches in full sun, overwatered shade areas, and frequent repairs.
At Blades of Glory Landscaping, we approach irrigation as a complete outdoor system—designed to support plant health, curb appeal, and responsible water use across San Antonio, Boerne, Stone Oak, Shavano Park, Rogers Ranch, and The Dominion.
Why irrigation fails early (and how to prevent it)
- Mixed head types/nozzle mismatching (uneven coverage)
- Poor zoning (turf, shrubs, and sunny beds on the same valve)
- Incorrect pressure (mist, fogging, and wind drift)
- No head-to-head coverage (dry spots that never catch up)
- Shallow trenching or lack of proper fittings (more leaks)
- Controller schedules that don’t match local rules or seasonal ET
The goal isn’t maximum runtime—it’s uniform distribution and the ability to fine-tune zones. Once the layout and components are correct, your controller settings become small adjustments instead of constant troubleshooting.
Did you know?
- The EPA estimates up to 50% of outdoor watering can be wasted due to overwatering and inefficient practices—smart controls and proper design help reduce that waste.
- Replacing a basic clock-based controller with a WaterSense-labeled smart controller can save an average home up to 15,000 gallons per year.
- In San Antonio, drip irrigation is allowed any day during permitted hours under year-round rules—making it an excellent option for beds, shrubs, and foundation plantings.
Step-by-step: How a professional sprinkler system installation should be planned
1) Site walk + irrigation goals
We confirm turf areas, bed lines, slopes, and hardscapes—and align the plan with your priorities (water savings, low-maintenance, best lawn appearance, or protecting new sod).
2) Water supply, pressure & flow check
Pressure and flow determine how many heads can run per zone without misting or weak coverage. This step prevents underperforming zones and chronic “dry edge” issues.
3) Smart zoning (hydrozoning)
Turf zones should be separate from shrub/bed zones. Sunny exposures should be separated from shade where possible. Drip zones should have the right filtration and pressure regulation.
4) Head selection and spacing
Rotor sprays vs. fixed sprays vs. drip each have a best use case. “Head-to-head” coverage (where spray reaches the next head) is one of the simplest ways to reduce dry spots without cranking up runtime.
5) Controller setup for San Antonio watering windows
A good controller schedule follows the local watering rules, adjusts seasonally, and avoids midday watering. Smart controllers help automate seasonal adjustments and reduce overwatering.
Use drip irrigation for foundation plantings and mulched beds whenever possible. It’s targeted, reduces overspray onto fences/walls, and fits well with year-round watering allowances.
Sprays vs. rotors vs. drip: what works best where?
| Irrigation Type | Best For | Pros | Watch-outs |
|---|---|---|---|
| Fixed sprays | Small turf areas, narrow strips | Great for tight spaces and edge control | Can run off on slopes if runtime is too long |
| Rotors | Larger lawns | More efficient for large areas; less misting when set correctly | Needs proper spacing and matched precipitation rates |
| Drip (low-volume) | Beds, shrubs, trees, foundations | Targeted watering; less overspray; good for water-smart landscapes | Needs filtration/pressure regulation; line breaks can go unnoticed |
San Antonio & Hill Country considerations (Boerne to Stone Oak)
Our region’s heat swings and soil variability can be dramatic from one neighborhood to the next. Here are the local factors that should influence your sprinkler system design and programming:
- Shallow/rocky soils: favor shorter cycles with soak time to reduce runoff (cycle-and-soak programming).
- New sod vs. established turf: new sod may need a short-term establishment plan, then a responsible long-term schedule.
- Watering rules: your controller must match the current SAWS watering stage and allowable times. Beds on drip can be especially helpful because drip is permitted daily during allowed hours under year-round rules.
- Backflow compliance: irrigation connections often require a backflow prevention assembly and annual testing under local requirements.
Project planning helpers (quick calculators)
Irrigation upgrades often go hand-in-hand with bed refreshes, edging, or hardscape improvements. If you’re planning materials, these tools can help you estimate quantities more confidently:
- Mulch Calculator — estimate coverage before you order.
- Gravel Calculator — helpful for paths, dry creek beds, and base layers.
- Concrete Calculator — useful if irrigation work connects with patio or edging projects.

FAQ: Sprinkler system installation in San Antonio
How many zones (valves) does a typical home need?
Most homes need multiple zones to separate turf from beds and to account for sun/shade differences. The “right” number depends on your water pressure/flow, yard shape, and plant layout—not a one-size-fits-all template.
Are smart controllers worth it?
If your goal is consistent curb appeal with fewer manual adjustments, yes. WaterSense-labeled controllers are designed to reduce overwatering and can save significant water over time, especially when paired with correct zoning and head selection.
Can I water every day if I switch to drip?
Under SAWS year-round watering rules (when no special drought stage is in effect), drip irrigation is permitted any day during allowed hours. Always confirm the current stage before programming a schedule.
Do I need backflow testing for my irrigation system?
Many properties with irrigation connections require a backflow prevention assembly and annual testing under local requirements (especially within the City of San Antonio/SAWS service area). If you’re unsure what you have, we can help identify the device and next steps.
What’s the best time to install or upgrade a sprinkler system?
Any time you’re changing the landscape (new sod, new beds, hardscape work) is a smart time to evaluate irrigation. It’s also a good idea to upgrade before peak summer heat so zones and run times can be dialed in early.
