Pressurized Irrigation Customers Receiving Water; Curtailment Is In Effect

Sprinkler Head

Homes connected to the City of Twin Falls’ Pressurized Irrigation system (PI) began receiving water April 25 and all subdivisions are currently operating. Curtailment is in effect so residents connected to PI are encouraged to check sprinkler systems for breaks and set watering schedules to avoid overwatering.

Residents can check the status of their subdivision’s pressurized irrigation at TFID.ORG and selecting 'Subdivision Pressurized Irrigation Status'.

Due to severe drought conditions, the Twin Falls Canal Company will start the 2022 irrigation season by delivering 5/8” to City Pressurized Irrigation Stations. Residents should expect additional curtailments, depending on drought conditions.

Homeowners who winterized their sprinkler systems will need to access a valve — generally near the sidewalk — for water to flow from the city pressurized irrigation lines to the home’s sprinkler system. Once activated, residents should check for damaged sprinkler heads, ‘bulging’ lawn turf that may indicate an underground leak, and spots that feel spongy due to overwatering.

Residents should schedule watering times over a 24-hour period to avoid overwhelming and shutting down pressurized irrigation stations. When too many homeowners irrigate at the same time — typically during mornings and evenings — the station serving the subdivision will shut down to prevent burnout. When this occurs, customers will receive little or no water to their sprinklers systems.

The city’s pressurized irrigation system reduces demand on the aquifer’s limited water supply by utilizing canal water for non-potable purposes — on average it has reduced Twin Falls’ demand on the aquifer by nearly 5 million gallons per day.
