Irrigation Dos & Don'ts
Irrigation Dos & Don'ts
Do
Water after the sun has gone down to avoid evaporation. Set sprinklers to run between 7:00 P.M. and 5:00 A.M.
Use low angle sprinklers that create drops of water to avoid evaporation losses.
Use proper water pressure to prevent misting, which is the result of pressure being too high and can lead to evaporative losses.
Use hydro zoning - watering needs grouped by types of landscaping, lighting, and soils.
Adjust your watering schedule seasonally. Less in spring, fall and cooler weather.
Use a moisture sensor to determine watering needs.
Use an in-line filter to prevent system clogs.
If supported, cycle the irrigation system - 4 minutes on, 4 minutes off, and repeat this cycle three times.
Use native plants to reduce watering needs.
Use micro-irrigation techniques, such as drip, trickle, bubblers, and / or micro-spray jets and sprinklers.
Consider allowing your grass to go dormant during drought conditions. Established grass doesn't die during dormancy.
Use a back flow prevention valve to avoid contaminating drinking water supplies (required in Ramsey).
Hold onto the design layout so future projects do not lead to necessary system repairs due to accidentally digging up water lines.
Don't:
Water too much (only need to water the root zone, which is about 5 to 8 inches deep for most common grasses).
Over-fertilize.
Use broken or impacted sprinklers.
Water hardscapes like driveways, sidewalks and building walls.
