Notice and timing
How delinquency is handled
Grace period after the due date
Bills are due upon presentation and become delinquent 25 calendar days later. For residential and non-residential accounts with an unpaid balance of $10 or more, IRWD applies a one-time 10% charge plus 1.5% interest after that delinquency point, followed by 1.5% interest each month on the unpaid balance. IRWD publishes a multistep 40-day residential discontinuation-notification process, so the 25-day payment period is not itself the physical shutoff date.
Late-fee calculation
Under the FY 2026–27 schedule, water, sewer, and recycled-water bills are due on presentation and delinquent after 25 calendar days. If at least $10 remains unpaid, IRWD assesses a one-time 10% of the unpaid balance plus 1.5% interest; each subsequent month adds 1.5% interest to the unpaid balance. A returned NSF check carries a $20 fee. Delinquent customers must pay the outstanding balance, late charges, interest, and applicable trip/reconnection charges before restoration, subject to listed exceptions and state-law limits.
Disconnection timeline
IRWD describes residential service protection as a multistep, 40-day notification process under California SB 998. The bill is presented, becomes delinquent after 25 calendar days, and late charges begin under the FY 2026–27 schedule. The District’s current residential policy provides notices, payment-arrangement opportunities, an appeals path, and fee limits before discontinuation; the final shutoff date must be read from the customer’s notices because the public summary does not give one universal calendar day from bill date. After shutoff, all delinquent charges and required restoration/dispatch charges must be paid; payments and arrangements can prevent interruption when kept current.
