Notice and timing
How delinquency is handled
Grace period after the due date
The exact residential grace interval is established by the due date printed on the monthly bill and the effective TMWA rules; TMWA's current 2026 rate sheet states that a 5% late charge applies to any amount in arrears from previous billings. The official public pages reviewed do not state one universal calendar-day grace period for every residential account.
Late-fee calculation
The current TMWA 2026 residential rate sheet lists a late charge of 5% of any amount in arrears from previous billings. This is separate from the 1.5% Regional Water Management Fee, any Reno/Sparks right-of-way toll, retail payment-provider fees, and any returned-payment or service charges authorized by the applicable rate schedule.
Disconnection timeline
The bill's printed due and past-due dates control the customer's account. TMWA's public current pages encourage customers to contact Customer Service promptly for a payment arrangement designed to prevent service interruption. Historical official TMWA collection materials describe a 10-day delinquent notice followed by a 48-hour notice for accounts eligible for disconnect, but the current public pages do not publish a single updated day-by-day residential shutoff schedule; customers should rely on the dated notice mailed to the account.
