In the past two years we have noticed an increase in the number of clients looking at ways to reduce the amount of water their irrigation systems use in order to reduce the cost of their water bill. Some municipalities have tripled the cost of irrigation water rates from just 5 years ago, leaving home owners with much larger water bills. The efficiency of an irrigation system’s water usage is measurable just like a car’s gas mileage. The first step in reducing your water bill will be to assess how efficient your current irrigation system is.


Let our irrigation system consultant visit your residential or commercial property and perform a thorough walk through of your irrigation system. Our consultant will record all necessary information about the irrigation system in order to achieve the following results: Improved Distribution Uniformity, Improved Reliability, and Establish an Irrigation Schedule.


1. Adjusting the water pressure at each head to a point that is within the manufacturers’ recommended range.

2. Installing the proper size nozzle in each head based on radius, arc and water availability.

3. Installing pressure compensating heads to even the pressure among all the heads on the zone.

4. Retrofitting poor performing fixed spray nozzles with nozzles that have much better application patterns as well as a slower application rate that will limit run-off.

5. Relocating heads that are not spaced properly or are now covered with landscape plantings.

6. Adjusting the heads that may be leaning or are too deep in the ground.


1. Reduce the water pressure on the main line, valves, lateral lines and heads to only that which is needed to operate the system.

2. Install check valves to help hold the water in the lines and the air out reducing water hammer.

3. Rebuild/Replace older zone valves and adjust the flow control so the valves shut off every time, on time.

4. Install, adjust or replace the rain sensor.


1. Assess the system zone by zone to complete appropriate site information.

2. Create an irrigation schedule based on information gathered along with methods developed by the Irrigation Association.

3. Install and program a “Smart Controller” that will change your irrigation schedule based on real time weather event.
