How Do I Know if My Irrigation System Is Efficient?
by John Vitulli | Smart Irrigation & Efficiency
Your irrigation system should be working for you – keeping your lawn green, your beds healthy, and your water bill under control. But when something isn’t right, your system can quietly waste thousands of gallons, stress your plants, and leave you paying for inefficiency you can’t see.
At Waterwise, we’ve been helping Houston homeowners and property managers fine-tune irrigation systems for more than 40 years. Here’s how to tell if your system is running efficiently – and what might be causing hidden problems.
Warning Signs Your System Isn’t Running Efficiently
Dry Spots in the Lawn or Beds
If parts of your yard are brown or wilting while others look lush, that’s a sign of uneven coverage. It usually means sprinkler heads are misaligned, clogged, or spaced incorrectly.
Pro-Tip:
Watch your system run zone by zone. If you see obvious “gaps” where water isn’t reaching, that’s your culprit – and likely an easy fix.
Pooling Water or Runoff
Water puddling around plants, on sidewalks, or running into the street means your system is applying more water than the soil can absorb
Pro-Tip:
Try cycle-and-soak watering – instead of one long 30-minute cycle, run three 10-minute cycles spaced 30–60 minutes apart. This gives the soil time to absorb water between cycles and drastically reduces runoff.
High Water Bills
A sudden spike in your bill often signals leaks, broken heads, or a controller running longer than necessary.
Myth vs. Fact
- Myth: “Summer bills are always sky-high.”
- Fact: While usage does increase in summer, a properly tuned system shouldn’t cause sharp, unexplained spikes.
Waterwise Insight:
A steady rise in cost – even by 10–15% — over several months often points to a small, slow leak or seeping valve.
Plants Looking Stressed
Drooping leaves, yellowing turf, or crunchy grass blades can mean your plants aren’t getting the right amount of water. Sometimes the problem is too much water, which suffocates roots and encourages fungus.
Seasonal Reminder:
Try cycle-and-soak watering – instead of one long 30-minute cycle, run three 10-minute cycles spaced 30–60 minutes apart. This gives the soil time to absorb water between cycles and drastically reduces runoff.
What Causes These Inefficiencies?
The warning signs are easy to spot – but the underlying causes can be surprisingly common. In the field, our technicians frequently find:
- Tilted or misaligned sprinklers spraying in the wrong direction.
- Sprinklers set too low (blocked by grass) or too high (exposed and easily damaged).
- Poor spacing that leaves gaps or creates wasteful overlap.
- Water-pressure issues – high pressure causes misting and evaporation, while low pressure reduces coverage.
- Mixed sprinkler types (rotors + sprays) on the same zone, applying water at different rates.
- Turf and flower beds sharing one zone, forcing very different plants to share a single schedule.
- No rain sensor or smart controller, causing the system to water during storms or ignore seasonal shifts.
Waterwise Advantage:
Our field inspections include a static pressure reading, zone-by-zone coverage evaluation, and head alignment checks to catch every one of these issues before they waste water.
Why Efficiency Matters
Small inefficiencies add up fast. They:
- Waste thousands of gallons of water every season.
- Drive up your utility bills.
- Stress your lawn and plants.
- Shorten the life of valves, nozzles, and sprinklers.
An efficient irrigation system keeps your landscape healthy while conserving Houston’s most precious resource – water.
Membership Tip:
Waterwise Membership customers receive seasonal inspections that include pressure testing, DU checks, and controller calibration to maintain year-round efficiency.
