As an Irrigation Engineer, you create watering systems for challenging projects. A common task for an Irrigation Engineer is irrigating agricultural crops, but you also work on other major projects, such as dams, canals, or drainage systems. Projects vary in terms of duration and construction requirements.
Irrigation is the artificial application of water to soil, in the correct amounts and frequency, for optimal soil infiltration and plant growth. To be effective soil type (sand, silt, clay), vegetation, size of the area to be irrigated, water pressure and local conditions should be considered.
FINE TUNE YOUR IRRIGATION SYSTEM:
Take time NOW to fine-tune your irrigation system and keep it running smoothly all summer with these 10 easy steps.
Adapt your watering schedule regularly to the weather and the season. Familiarize yourself with the settings on your irrigation controller and adjust the watering schedule regularly.
Schedule watering for each zone separately. For each area, take into account the type of sprinkler, sun or shade exposure, soil type and plant requirements.
Water more frequently but for shorter periods of time. Setting your system to run for three, 5-minute intervals lets soil absorb more water than watering for 15 minutes at one time.
Water at the right time of day. Watering when the sun is low, winds are calm and temperatures are cooler minimizes evaporation by as much as 30 percent! The best times to water are late afternoon, evening and just before sunrise.
Water only when needed. Saturate root zones and let the soil dry. Overwatering results in shallow roots and encourages weeds, disease and fungus growth. Irrigation water can be especially damaging as soil salinity rises. Read more at Irrigation Water is Destroying your Landscape.
Have your system audited. Hire a professional to conduct an irrigation audit and uniformity test to make sure each zone is being watered evenly.
Inspect your system yourself. If an audit isn’t in the budget make sure that you are checking at least monthly for leaks, broken or clogged heads, and other problems that arise from normal wear and tear.
Install an inexpensive rain shutoff switch. These money saving sensors prevent watering in rainy weather when you forget to shut it down or aren’t around to do it. The best part? You can pick one up for less than $100.
Invest in “smart” technology. Climate or soil moisture sensor-based controllers evaluate weather or soil moisture conditions and then automatically adjust the watering schedule to meet the specific needs of your landscape.
Adjust sprinkler heads. Remove obstructions that prevent sprinklers from distributing water unevenly and make sure you’re watering plants, not buildings or sidewalks.
