Full Breakdown
Under section 7-8-14(A), landscape irrigation from the city of Twin Falls potable water source runs on a three-day schedule keyed to the address. Even numbered addresses water Tuesday, Thursday and Saturday. Odd numbered addresses water Wednesday, Friday and Sunday. Premises with no street address, such as a median, water Monday, Wednesday and Friday. Watering on those days is allowed only before ten o'clock A.M. or after five o'clock P.M. Drip irrigation systems and handheld containers are allowed at any time, and vehicles are washed only on the scheduled irrigation day.
Customers using TFCC shares through a pressure irrigation system follow calendar days instead: even numbered addresses irrigate on even calendar days, odd numbered addresses on odd calendar days, and premises with no address every other day. City facilities are limited to three days a week on potable water and every other day on pressure irrigation.
The City Council can tighten the schedule in stages based on engineering evaluation of projected supply and demand. Stage 1 cuts landscape irrigation to two days a week (even addresses Tuesday and Saturday, odd addresses Wednesday and Sunday). Stage 2 allows one day a week (even Tuesday, odd Friday). Stage 3 allows two days per month (even addresses second and fourth Tuesday, odd addresses first and third Friday). Every stage bans applying water to impervious surfaces such as streets, sidewalks, patios and decks. Section 7-8-14(C) lets the council add limits, including a ban on outdoor watering except for large trees with trunks of at least six inches in diameter and a ban on filling water features, pools or ponds.
Irrigation systems can run at any time for maintenance, not to exceed 10 minutes per station, and a customer can apply for relief of up to three months to establish a new lawn. A customer can also file an alternative water management plan with the city's water conservation committee. Section 7-8-4(E) separately prohibits potable water as the primary irrigation source in new developments unless approved by the City Engineer.
Violations & Fines
Each water customer answers for compliance at the customer's own premises. Through Stage 2: first violation, written warning; second, a $40 fine; third, $80; fourth and subsequent, $120. Through Stage 3: first violation $80, second $160, third and subsequent $240. Fines are added to the water bill. A fine can be appealed in writing to utility billing within 15 days of the billing date, to the water conservation committee, then to the City Council within 15 days of the decision.
