Billing Cycles and Level Pay

Depending on where you live in the City of Twin Falls, residential billing occurs on the first, fifth, 10th, 15th, 20th or 25th of each month. Industrial and commercial customers are billed on other dates. 

Utility payments are due twenty-one (21) days after the billing date and are delinquent after thirty-one (31) days. Delinquent payment arrangements can be made using the designated button above. Amounts due for previous months’ bills, which are unpaid at the time of the next billing date, will be assessed a penalty.

Each September, customers who have completed one year of service with no late payments may elect to have their estimated water bills averaged out over the year.
