How to Pay a Port St. Lucie Water Bill

A Port St. Lucie water and sewer bill can be paid online, through the phone line at 772-873-6400, by mail to PO Box 8987, at a City Hall drop box or in cash at City Hall (Port St. Lucie Utility Billing and Accounts page).

Online payment covers the monthly water bill, utility deposits and new residential construction applications, by check, credit or debit card (Port St. Lucie Utility Billing and Accounts page). The billing page lists VISA, Mastercard, AMEX, Discover, Google Pay, Apple Pay, eCheck, PayPal, PayPal Credit and Venmo as accepted methods. A one-time payment without logging in needs the 13-digit account number printed in the upper right corner of the Port St. Lucie utility bill (Port St. Lucie Utility Billing and Accounts page).

By phone, the same number routes callers by keypad: press 1 to make a payment, 2 to report a water or sewer emergency and 3 to reach a Connection Support Specialist (Port St. Lucie Utility Billing and Accounts page). Checks and money orders go by mail to PO Box 8987, Port St. Lucie, FL 34985, or into a drop box at City Hall, 121 SW Port St. Lucie Blvd., with the account information attached (Port St. Lucie Utility Billing and Accounts page).

Cash is taken only in person. The billing page says customers can visit City Hall to pay in cash either by appointment or as a first-come, first-served walk-in (Port St. Lucie Utility Billing and Accounts page).

Yes: card, PayPal and Venmo payments carry a 2.75% fee with a $1.95 minimum, e-checks carry $0.95, and a mailed or dropped-off check or money order carries none (Port St. Lucie Utility Billing and Accounts page).

The billing page states that the City of Port St. Lucie does not receive any portion of the service fee charged by credit card companies (Port St. Lucie Utility Billing and Accounts page). The residential customer service guide puts it more directly: the processor assesses the fee for the convenience of paying electronically, and residents can avoid it by paying with a check or money order (Utility Systems residential customer service guide).

The Port St. Lucie guide also separates two kinds of electronic payment. A bill-pay transfer sent from a customer's own bank as an EFT or ACH transaction is not affected, while an e-check entered through the city's online system is charged the $0.95 fee (Utility Systems residential customer service guide). Its worked example uses an average monthly water and sewer bill of $93.19, which stays $93.19 when paid by mailed or dropped-off check and becomes $95.75 when paid by card, digital wallet, Venmo or PayPal (Utility Systems residential customer service guide).

Port St. Lucie autopay does not escape the processor fee. The guide says customers on auto-pay see the service fee that matches the payment method on file, and the billing page marks the autopay and phone options with the same fee note (Utility Systems residential customer service guide; Port St. Lucie Utility Billing and Accounts page).

All three run through a registered online account, which a new Port St. Lucie customer can create only after the first bill has been generated (Port St. Lucie Utility Billing and Accounts page).

Once registered, a customer can review invoice and payment history, schedule automatic payments, pay with saved payment information and enroll in pay-by-text (Port St. Lucie Utility Billing and Accounts page). Autopay uses a checking account or credit card and drafts the payment automatically on the bill due date, which the city presents as a way to avoid late fees (Port St. Lucie Utility Billing and Accounts page).

Paperless billing is a setting inside the account: the option sits in the upper right corner of the account homepage (Port St. Lucie Utility Billing and Accounts page). The Utility Systems Department page promotes the same paperless switch on its front page, alongside pay-by-text enrollment (Port St. Lucie Utility Systems Department page).

Customers who cannot find an account number can email Utility Connection Support at utility@cityofpsl.com or call 772-873-6400 (Port St. Lucie Utility Billing and Accounts page). Homeowners repaying a septic to sewer grinder installation loan find that balance on the most recent invoice or by calling Connection Support (Port St. Lucie Utility Billing and Accounts page).

Port St. Lucie utility bills are due when rendered and become delinquent if not paid within 20 days after they are issued (Port St. Lucie New Customers page).

The New Customers page says service in delinquent shut-off status is restored after all past due bills and a $65 reconnect fee are paid (Port St. Lucie New Customers page). The residential customer service guide lists a late fee of $2.00 plus 1.5% of the past due amount in its schedule of miscellaneous charges, a schedule it labels effective October 1, 2025 (Utility Systems residential customer service guide).

A customer who needs more time can request a payment extension online. The billing page says responses usually come within the same business day and no later than 24 hours (Port St. Lucie Utility Billing and Accounts page). For service already disconnected for nonpayment, the Contact Utility Systems page directs customers to (772) 873-6400, the same number used for maintenance emergencies (Contact Utility Systems page).

Billing questions go to the Customer Service and Billing desk on weekdays from 8 a.m. to 5 p.m. by phone at (772) 873-6400 or by email to utility@cityofpsl.com (Contact Utility Systems page). Administration and Field Operations at 1001 SE Prineville St. work 24 hours a day, 365 days a year, and the billing page lists 772-871-1775 as an alternate phone (Contact Utility Systems page; Port St. Lucie Utility Billing and Accounts page).

Port St. Lucie bills water in thousand-gallon increments and adds a fixed base facility charge, so small changes in use often do not move the bill (Port St. Lucie Utility Billing and Accounts page).

The billing page gives its own example: 1,900 gallons of use shows as 1,000 gallons billed, and the remaining 900 gallons are billed once they reach the next thousandth gallon (Port St. Lucie Utility Billing and Accounts page). The base facility charge, which the city also calls a readiness to serve fee, applies to every water, wastewater or reclaimed water bill whether or not any water was used that month (Port St. Lucie New Customers page).

A high bill after time away has two common explanations on the New Customers page: the absence may have overlapped the monthly billing period, or there may be a leak in a toilet, faucet or service line (Port St. Lucie New Customers page). The same page says the city may estimate a bill from past use on rare occasions such as after a severe weather event, and that residential sewer charges are based on metered water and stop counting at 8,000 gallons (Port St. Lucie New Customers page).

The Port St. Lucie customer service guide describes a two-hour leak check: with every tap off, the meter is read, no water is used for about two hours, and the meter is read again; different readings mean a leak (Utility Systems residential customer service guide). The meter sits outside the home in a plastic box in the ground and is city property (Utility Systems residential customer service guide).

Two Port St. Lucie billing details read differently on the city's web pages and in its residential customer service guide, whose printed rate schedule dates from October 1, 2025 (Utility Systems residential customer service guide).

The Utility Systems Department page says City Council adopted utility rates and fees that take effect on October 1, 2026 (Port St. Lucie Utility Systems Department page), while the residential customer service guide states that its schedule of rates and charges went into effect on October 1, 2025 (Utility Systems residential customer service guide).

The billing page names the three drop boxes: a curbside box in the roundabout between the Police Department (Building C) and City Hall (Building A) and a walk-up box near the east side accessible parking, both available 24/7, plus one inside the City Hall lobby during open hours (Port St. Lucie Utility Billing and Accounts page). Payments dropped after 4 p.m. are processed the next business day.

Homes in St. Lucie West are a separate case: the St. Lucie West Services District runs its own water and wastewater billing, with its own Pay My Bill link, and describes itself as a community development district overseeing St. Lucie West (St. Lucie West Services District). The Port St. Lucie utilities guide covers deposits, starting service and septic conversions.
