Port Saint Lucie Utilities: Pay Bill, Login & Phone 2026
City of Port St. Lucie Utility Systems • Water & sewer customer guide
If you need to pay a City of Port St. Lucie utilities bill, sign in to your account, make a payment without logging in, start water or sewer service, request more time to pay or report a utility emergency, the correct department is the City of Port St. Lucie Utility Systems Department.
The City primarily handles water and wastewater service. That distinction matters because not every utility account with a Port St. Lucie mailing address belongs to the City; some properties can be served by another local utility district.
Port St. Lucie Utility Billing Quick Answers
The number appears in the upper-right area of the City’s utility bill. Keep the bill nearby before opening guest payment.
The City says new customers must wait until the first utility bill has been generated before registering an online account.
Utility Systems says extension requests are typically answered the same business day and no later than 24 hours.
First Check: Is the City of Port St. Lucie Actually Your Utility?
Port St. Lucie Utility Systems covers the City and portions of unincorporated St. Lucie County. Its customer guide describes a service area of more than 120 square miles with more than 98,000 customers.
However, a Port St. Lucie mailing address does not guarantee that the City is the water provider. St. Lucie West Services District operates a separate utility system with its own customer-service department, rates and payment system.
After opening the St. Lucie West Services District page
- Check whether the provider name matches the name printed on your bill.
- If your account belongs to the District, use its customer-service and payment information rather than the City of Port St. Lucie portal.
- If you still cannot identify the provider, use the service address when calling the organization listed on your bill.
How to Pay a Port St. Lucie Utility Bill
City water and sewer customers can pay online, by phone, by mail, at City Hall or through a drop box. Electronic payments carry processor fees, so the cheapest method is not always the fastest method.
Review invoices and payment history, use saved payment information, schedule automatic payments and enroll in pay-by-text.
Use the 13-digit utility account number found in the upper-right area of your bill.
The City’s phone system accepts utility payments and applies the applicable electronic-payment fee.
Send a check or money order. Allow enough delivery time when the account is close to its due date.
Three City Hall drop-box options are listed. Payments placed after 4 p.m. are processed the next business day.
The City says customers can make cash payments at City Hall by appointment or as a walk-in.
After opening the official billing page
- Choose Register/Login if you want full account access, or use the no-login payment route for a one-time payment.
- For guest payment, copy the 13-digit account number from the upper-right area of your utility bill.
- Select the payment method offered by the City’s authorized processor.
- Review the processing fee before submitting the transaction.

An extension is not the same as an automatic approval. If service is already disconnected, or the shutoff deadline is immediate, call Utility Systems directly rather than waiting for an online response.

- Submit the account and contact information requested by the City.

| Charge | Current published rate | How it applies |
|---|---|---|
| Water-only base charge | $13.11 | 5/8″ × 3/4″ residential meter. |
| Water base charge with water + sewer | $11.16 | Standard 5/8″ × 3/4″ meter. |

| Water: 0-5,000 gallons | $5.23 / 1,000 gallons | First water-usage block. |
| Water: 5,001-12,000 gallons | $6.81 / 1,000 gallons | Second block. |

After opening the official customer guide
- Use the residential rate pages for household water and wastewater rates.
- Find the meter size printed on your bill or account record.
- Separate the monthly base facility charge from consumption charges.
- Match water use to the applicable gallonage blocks.
- Use the wastewater cap when checking a residential sewer charge rather than multiplying unlimited water use by the sewer rate.
Why a Port St. Lucie Utility Bill Can Look High—or Stay Exactly the Same
Port St. Lucie bills water in 1,000-gallon increments. That can make two consecutive bills look identical even when your meter recorded some additional use.
The City gives this example: if a household uses 1,900 gallons, the bill may initially show 1,000 gallons. The remaining usage carries forward until it reaches the next thousand-gallon billing increment.
A second reason is the Base Facility Charge. This is a readiness-to-serve charge that applies even when little or no water is used.
High Bill Troubleshooting
A leaking toilet or faucet can add water use every hour, even while no one is intentionally using water.
The bill period may overlap days before or after your trip, and base charges continue while service remains active.
Irrigation or a leak can push some water use into the $6.81 or $8.38 per-thousand-gallon blocks.
Water, Sewer Alarm or Utility Emergency
Call 772-873-6400 for a Utility Systems maintenance emergency, water or sewer problem, a sewer alarm that is sounding or flashing, or service disconnected for nonpayment.
Use for the automated payment route.
Use for emergency utility routing.
Use for billing and account help.
Hurricane and Power-Outage Detail
Port St. Lucie says a normal electric outage should not stop City water production because its water-treatment facilities operate with generator backup.
Homes on private wells are different: the well pump normally requires electricity, so loss of power can interrupt household water even when the City’s public water system remains operating.
