Deposits are credited back to the account after two years of on-time payments and never having appeared on the turn-off list. Residential water service deposit amounts are equal to two times the average monthly consumption for the past 12 consecutive months for the property. Residential sewer deposits are $103.
  • Water and sewer bills are due and payable upon receipt; delinquent 2) days after the billing date.
  • If an account is delinquent for non-payment, a delinquent fee of 10% of current charges per month plus 1.5 percent of past-due charges on the total amount due will be added to the bill.
  • If a bill includes a prior unpaid balance, the customer will have 10 days from the next regular billing date to pay the prior balance. Turn off procedures will begin if payment is not received by the end of the ten days and a turn-off list processing charge of $58.33 will be added to your bill.
  • If service is disconnected and restoration is requested after working hours, weekends or holidays, the restoration charge shall be $93.45, payable by noon of the next working day. No water shall be turned on after 8 pm or before 7 am.
  • Ten days after service has been discontinued, if the account remains unpaid, the customer's deposit will be applied to the unpaid balance and the account will be closed. Service will not be resumed until a deposit is reconstituted and all outstanding charges have been paid.
  • Payments received one day prior to the date of the bill do not appear on the bill due to necessary processing time.
  • Please be aware, per City of Rialto Resolution Number 5074 and Number 4746, ready to serve charges are billed monthly, whether or not the property is occupied. If the property becomes vacant, ready to serve charges become the responsibility of the owner.
