Sometimes I see irrigation systems running between the hours of 11:00 am and 6:00 pm. I thought it was against the city ordinance to water during this time period?
Much confusion seems to exist on this issue. The ordinance prohibits irrigation with any ‘spray’ type system such as impact sprinklers, rotors, or pop-up spray heads. Drip irrigation is allowed any time of the day. Section 106-186 subsection (d)(1) of the ordinance states that “landscape watering is permitted any time with a hand held hose, soaker hose, bucket, watering can, bubbler or drip irrigation system.” The reason for prohibiting spray systems during those hours is that 25% or more of water sprayed into the air evaporates before it ever hits the ground even under the best of conditions. The hotter the air temperature and the higher the wind speed, the greater the amount of evaporation. In contrast to spray systems, drip irrigation systems deliver the water directly to the soil with almost 100% efficiency regardless of the air temperature or wind speed.
