Water and Sewer Rates in Port St. Lucie, Florida

Port St. Lucie water and sewer rates in effect since Oct. 1, 2026, come from Ordinance 26-86, which raised the water rate 3.5% and left wastewater rates unchanged (adopted rate increase page).

Every Port St. Lucie utility bill has two parts: a monthly base facility charge, which the city also calls a readiness to serve fee and applies whether or not any water is used, and a gallonage charge based on metered use (Ordinance 26-86, section 62.12). The base charge depends on meter size, from the 5/8 by 3/4 inch meter up to 2 inches.

The figures are the underlined, newly adopted amounts in section 62.12 of Ordinance 26-86; the struck amounts beside them are the prior rates. The City Council took the ordinance through first reading on Sept. 14, 2026, and second reading on Sept. 28, 2026 (Ordinance 26-86), and the Port St. Lucie Utility Systems Department home page announced that the adopted rates and fees take effect on October 1, 2026 (Utility Systems Department). The city says the increase helps finance higher operating costs and fund capital improvement projects (adopted rate increase page).

Port St. Lucie charges residential water in three rising blocks per 1,000 gallons, $5.41, $7.05 and $8.67, and wastewater at $8.27 per 1,000 gallons up to an 8,000 gallon monthly cap (Ordinance 26-86).

The Port St. Lucie Residential Customer Service Guide explains the design: the consumption charge is at an inclining rate to promote conservation of water resources (Residential Customer Service Guide). Sewer charges follow metered water use, so a home pays wastewater on the same gallons that pass through its water meter, but the New Customers page states that residential sewer charges cap out at 8,000 gallons of metered water use (New Customers page).

Seasonal owners often ask why a Port St. Lucie bill keeps arriving while they are away. The New Customers page answers that the city's utility rates are structured so that all customers share in the fixed cost of providing utility service, and a bill can also run high because time away overlapped the billing period or because of a leak in a toilet, faucet or service line (New Customers page).

Port St. Lucie condominiums and townhomes pay a per-unit base charge of $6.80 for water and $14.93 for wastewater, nonresidential accounts pay per ERC reserved, and sewer-only homes pay a flat monthly rate (Ordinance 26-86).

For nonresidential Port St. Lucie accounts, which the ordinance says include commercially leased residential properties such as apartment complexes, the water block thresholds are 5,000 and 12,000 gallons multiplied by the number of ERCs reserved, and wastewater is billed on total metered water use (Ordinance 26-86). Reclaimed water carries its own base charge, set per 1,000 gallons of capacity reserved.

The ordinance also restates a rule that matters at a sale: Port St. Lucie holds a lien on all lands or premises served for unpaid water, reclaimed water or sewer charges, on a parity with state, county and municipal tax liens under section 159.17, Florida Statutes (Ordinance 26-86, section 62.12(b)).

A new Port St. Lucie utility account needs a deposit of $70 for water only or $180 for water and sewer (New Customers page).

The two city documents disagree on when the deposit comes back. The New Customers page says deposits are refunded after a satisfactory payment record for 18 months (New Customers page), while the Residential Customer Service Guide says the deposit will be refunded after 36 consecutive months of satisfactory credit (customer service guide). The city's adopted rate increase page lists Utility Systems Connection Support at 772-873-6400 for more information (adopted rate increase page).

Service changes have their own fees on the Port St. Lucie New Customers page. A routine turn-on or turn-off for the next business day is free, while same-day service costs an additional $50 collected in advance. Turning water off for a vacation costs nothing, but reconnection costs $50, and service cut off for nonpayment is restored only after all past due bills and a $65 reconnect fee are paid (New Customers page). Owners can close their own house valve, but only authorized city personnel may touch city pipes and meters.

Port St. Lucie's October 2026 conversion schedule charges $7,335 to $19,532 paid in full, depending on the service and whether the lot sits in a utility special assessment area, with a 10-year interest-free payment option (water and sewer conversion rates, Oct. 2026).

The Port St. Lucie conversion sheet says some households may receive a grant for up to 50% of the cost of connection, awarded first-come, first-served while funding lasts, and that owners who do not qualify can finance all or part of the cost over 10 years interest-free; the Connection Support Office in City Hall at 772-873-6400 checks grant eligibility (conversion rates sheet). The New Customers page links the same conversion fees, effective Oct. 1, 2026, and asks for the driver's licenses of all owners on the deed when applying (New Customers page).

Two earlier dated Port St. Lucie rate documents remain posted, one headed effective October 1, 2025, and one headed effective October 1, 2024 (Residential Customer Service Guide; Schedule of Rates and Charges, October 2024).

The Port St. Lucie Residential Customer Service Guide carries rate pages headed Ordinance 25-51, effective October 1, 2025 (customer service guide), and the Schedule of Rates and Charges is headed effective October 1, 2024, under Ordinance 21-91 (October 2024 schedule).

The rates now in effect are the ones adopted in Ordinance 26-86, which states that its rates, fees and charges become effective October 1, 2026, and which the City Council passed and adopted on Sept. 28, 2026 (Ordinance 26-86, section 13). The guide's own billing page says the schedule of rates and charges it prints went into effect on October 1, 2025, and the guide also carries a table of average residential water and wastewater bills by household size dated to that schedule (customer service guide). For the current figures, the city's adopted rate increase page links Ordinance 26-86 and displays an example of an average residential bill, and it lists Utility Systems Connection Support at 772-873-6400 and utility@cityofpsl.com for questions (adopted rate increase page).

St. Lucie West is a separate case. Homes there are customers of the St. Lucie West Services District, whose site carries its own utility accounts and billing links, so the Port St. Lucie city schedule above does not set their charges (St. Lucie West Services District). Last verified: October 22, 2026, against the rate tables of Ordinance 26-86, the city's adopted-rate and New Customers pages, the October 2026 conversion sheet, the customer service guide and the October 2024 schedule.
