Payment research for this provider
The compiled notes distinguish confirmed channels from details the public material did not expose. Fields containing only an unavailable-information marker are grouped in the research record below.
- Payment platform
- The current GCWW customer-facing portal does not name its underlying portal vendor in the official pages reviewed. Promise Network Inc. operates the separate GCWW PromisePay payment-plan portal for delinquent balances.
- Phone payment number
- (513) 591-7700 is GCWW's automated self-service payment line and customer-service number. It accepts checking/savings-account or debit/credit-card payments and is also the 24-hour water-emergency number; normal customer-service office hours are Monday-Friday 7:30 a.m.-4:30 p.m.
- Pay-by-text
- GCWW does not publish a direct utility text-to-pay keyword or standalone SMS bill-payment enrollment on its current payment pages. PromisePay payment-plan participants can opt into text reminders and notifications after enrolling at https://gcww.promise-pay.com; those reminders supplement, rather than replace, the GCWW portal and payment process.
- Mail-in payment address
- Greater Cincinnati Water Works, P.O. Box 740689, Cincinnati, OH 45274-0689. Mail a check or money order with the payment stub/account number; mailed checks are one of the current no-transaction-fee payment options, and cash should not be mailed.
- In-person payment
- GCWW's main customer-service location is 4747 Spring Grove Avenue, Cincinnati, OH 45232; customer-service hours are Monday-Friday 7:30 a.m.-4:30 p.m. A drive-up drop box in the front parking lot accepts envelopes with non-cash payments. Customers may also use the portal's Pay Now/cash option to generate an account barcode and pay cash at participating local retailers; the official pages direct customers to the portal retailer map rather than publishing one fixed store list. The GCWW office phone is (513) 591-7700, and no current counter schedule for cash/card walk-in payments was separately published.
- Digital payment methods
- The enrolled GCWW portal supports checking and savings-account payments, electronic-check AutoPay, and account management. Credit and debit cards are available through the Guest Payment Tool and by phone, with the transaction fee. The separate PromisePay plan supports e-check, credit/debit cards, Apple Pay, Google Pay, and Venmo. Customers can also use their own bank's online bill-pay service without GCWW's transaction fee.
- Online convenience fees
- A non-refundable flat $1.90 residential transaction fee applies to over-the-phone payments, one-time guest web payments, and credit/debit-card payments; the business fee is $9.95. GCWW says the processor retains the fee and the utility receives none of it. Payments from a checking or savings account through an enrolled portal account, a customer's bank bill-pay service, and mailed checks or money orders remain free of this GCWW transaction fee.
