St. Lucie County Utilities Water and Sewer

St. Lucie County Utilities provides drinking water, sewer and reclaimed water only in the unincorporated part of St. Lucie County, while Port St. Lucie and Fort Pierce customers are served by their own city utilities.

The St. Lucie County Utilities FAQ lists potable (drinking) water, wastewater (sewer) and reclaimed water, described as processed wastewater suitable for irrigation, for residences and businesses in the unincorporated portion of St. Lucie County, and states that reclaimed water is not available for single-family homes. The county publishes its charges as the St. Lucie County Water District rate schedules (rate schedules).

Homes inside the cities pay a different utility. The City of Port St. Lucie runs its own Utility Systems Department, whose rates and fees, adopted by the City Council, start October 1, 2026 (Port St. Lucie Utility Systems). Fort Pierce water and wastewater come from the Fort Pierce Utilities Authority, which lists its current water rates under Resolution UA 2026-04 and wastewater rates under UA 2026-05, with an outage and trouble line at (772) 466-7703 (FPUA rates and resolutions). The Port St. Lucie and Fort Pierce utility guides cover those systems; this guide stays with the county utility.

Service with St. Lucie County Utilities starts with a service request application, a driver's license or ID, a copy of the lease or title, and the deposit, handled by email, by phone at 772-462-1150 or in person in Fort Pierce.

The St. Lucie County Utilities Apply for Service page offers three routes: email the completed application to Util@stlucieco.org, call Customer Service at 772-462-1150 Monday to Friday 8:00am to 5:00pm excluding holidays, or visit the office at 2300 Virginia Avenue, at the northwest corner of Virginia Avenue and S. 25th Street in Fort Pierce. A property that has never had water or wastewater service needs the New Customer Application, ID, the title and all connection fees and deposits. The page says installation typically happens within two business days of the application but may take four weeks or longer when construction or permitting is involved.

For moves within St. Lucie County, the utility FAQ says to call Customer Service at 772-462-1150, which provides the list of documents needed to set up, transfer or close an account. A billing address can be changed by phone, by email to utilities_customer_service@stlucieco.org, or by filling in the change of mailing address on the back of the payment stub. The two county pages list slightly different counter hours: the FAQ gives lobby hours of 8:00 a.m. to 4:30 p.m. and phone hours of 8:00 a.m. to 5:00 p.m., while the Apply for Service page lists the office as open 8:00am to 5:00pm, Monday to Friday.

An average single-family home in unincorporated St. Lucie County pays an $85.00 water deposit and an $89.00 sewer deposit where sewer is provided, and the deposit comes back after two years of good payment history.

Those amounts appear on the St. Lucie County Utilities FAQ and match the minimum deposits for a 5/8 inch meter on the rate schedule, which rises with meter size to $118.00, $234.00 and $469.00 for 1 inch, 1 1/2 inch and 2 inch water meters. Commercial deposits are set by meter size and master-metered accounts by meter size and number of units, so those customers call 772-462-1150 for a figure. On a St. Lucie County single-family account, the FAQ says the deposit is applied to the account after two years of excellent payment history or when a final bill is issued, and the Apply for Service page describes deposits as eligible for refund after 24 months of satisfactory credit.

Under rates effective 8/1/2026, a St. Lucie County home on a 5/8 inch meter pays a $26.33 water base charge and a $30.46 sewer base charge, plus usage charges starting at $7.11 per 1,000 gallons.

The figures above are copied from the residential section of the St. Lucie County Water District rate schedules. On that schedule, St. Lucie County sewer usage stops being billed at 10,000 gallons while the water tiers keep rising. Separate irrigation meters are billed at $11.04 per 1,000 gallons up to 15,000 gallons and $12.87 above that. The residential schedule also lists a non-metered wastewater service charge of $47.47 and a sewer base facility charge of $89.43.

Other St. Lucie County charges on the same schedule include $47.00 for a normal reconnection during business hours, $134.00 for an after-hours reconnection, $57.00 for a violation reconnection, $47.00 for a premises visit in lieu of disconnect and $47.00 for a meter test request on 5/8 inch to 1 1/2 inch meters. Multi-family and commercial accounts in St. Lucie County are billed under separate sections of the schedule, covered below.

Multi-family buildings on a St. Lucie County master meter pay $18.73 per unit for water and $26.10 per unit for sewer, while commercial accounts pay a $39.49 water base charge per ERC and deposits set by meter size.

The multi-family section of the St. Lucie County Water District rate schedules covers service through a master meter for residential uses. Deposits equal two months of estimated bills, water use is tiered from $7.11 per 1,000 gallons for the first 2,500 gallons up to $12.87 above 7,500 gallons, sewer use is $9.16 per 1,000 gallons at every tier, and a temporary construction meter deposit is $280.00. Reclaimed water, which the county does not offer to single-family homes, is priced in this section at $4.11 per 1,000 gallons, and master-metered fire protection water is $11.36 per 1,000 gallons.

Commercial and industrial St. Lucie County customers are charged a customer account charge of $3.26 per bill and water use of $7.11 per 1,000 gallons up to 5,000 gallons, $8.32 up to 10,000 gallons and $11.04 above that, according to the commercial section of the same rate schedule. The residential and multi-family sections of the St. Lucie County schedule both list a $300.00 administrative fee and a $4,897.00 developer agreement fee.

St. Lucie County Utilities bills can be paid online, by phone, by mail, by automatic bank draft, at a kiosk or in person, and only cash, check or money order at the counter, mail and bank draft avoid a fee.

The St. Lucie County Pay My Bill page lists the costs. Online payments post the same day and cost $2.65 per card transaction, up to a $220.00 limit, or $2.00 per check or ACH transaction. The kiosk charges $2.65 per card and $1.00 per check or ACH. Phone payments run from 8:00 am to 4:30 pm on weekdays with a $2.65 card fee. Mailed payments go to P.O. Box 728, Fort Pierce, FL 34954-0728, the address on the St. Lucie County Utilities FAQ, and the Pay My Bill page says they post on the day they reach the Utilities Office; automatic bank draft debits the account on the due date after an application and a voided check are on file.

One warning on the St. Lucie County payment page matters more than the fees: if a payment is past due, an account is scheduled for shut-off, or service is already off, the customer must not pay online and must call the Customer Service Center at 772-462-1150 instead (Pay My Bill). In-person card payments, like phone payments, post the same day only when made before 4:30 p.m.

St. Lucie County Utilities serves the unincorporated area, and Port St. Lucie and Fort Pierce customers are billed by their own utilities, so their bills, rate schedules and payment channels come from Port St. Lucie Utility Systems and the Fort Pierce Utilities Authority.

The Port St. Lucie Utility Systems page lists online payment by check or card, two City Hall drop boxes (121 SW Port St. Lucie Blvd), a payment phone line open 24/7 at 772-873-6400 and a mailing address of PO Box 8987, Port St. Lucie, FL 34985, and notes paperless billing and pay-by-text. The Fort Pierce Utilities Authority rates page posts water and wastewater rates as separate resolutions, UA 2026-04 for water and UA 2026-05 for wastewater, alongside its electric and natural gas rates. The water resolution itself records that the FPUA was created by a Fort Pierce referendum held on May 30, 1972, and that UA 2026-04 applies a 2.23% increase to customer and volume charges tied to the Florida Public Service Commission's 2025 annual price index (FPUA Resolution UA 2026-04).

Card payments also cost differently across St. Lucie County. Port St. Lucie applies a 2.75% fee to credit, debit, PayPal and Venmo payments with a minimum charge of $1.95, and processes drop-box payments made after 4 p.m. on the next business day (Port St. Lucie utility billing page), while the county utility charges a flat $2.65 per card transaction.

The county utility FAQ defines the St. Lucie County system by the unincorporated area, and an address inside either city sits outside the area that FAQ describes.
