Start Water Service in Port St. Lucie

A new resident moving into a Port St. Lucie home that already has city water applies online through the Start Service (Move In) request, then pays a deposit once Utility Systems sends instructions.

The city's Start, Stop or Transfer Service page sorts requests into five online forms (Start, Stop or Transfer Service, City of Port St. Lucie).

For a Port St. Lucie home with existing city service, the New Customers page wants a government-issued ID (a copy or a picture of it), the full service address and the requested start date (New Customers, Port St. Lucie Utility Systems). The page says the deposit is required to complete the application and that the city makes contact after the application arrives with instructions for paying it.

As posted on the Port St. Lucie New Customers page on October 22, 2026, the deposit is $70 for a water only account and $180 for a water and sewer account.

Those two Port St. Lucie amounts appear in the requirements block for homes with existing service (New Customers page, deposit amounts as posted). The billing page lists utility deposits among the payments accepted online (Utility Billing & Accounts, Port St. Lucie). Deposit refund terms, monthly charges and service fees are set out in the Digital Towns guide to Port St. Lucie water and sewer rates.

On turn-on day a Port St. Lucie service technician opens the water and reads the meter, and that reading becomes the starting point for the first bill.

The Port St. Lucie Residential Customer Service Guide asks for one business day of advance notice and suggests that someone be at the new address that day, because fixtures left in the ON position could cause flooding and water damage (Residential Customer Service Guide, applying for residential service). If nobody is home and the meter dial is moving, the guide says the technician turns the water back off, leaves a door hanger, and an additional $50 service charge goes on the bill. A location that never had water or wastewater service needs a full application and payment of all required fees instead.

A same-day turn-on costs extra; the two city documents state that charge differently, and the Digital Towns guide to paying a Port St. Lucie water bill sets both amounts side by side.

A customer moving within the Port St. Lucie service area can end service at the old address and begin it at the new one with a single telephone call, provided the old account is paid up.

According to the Port St. Lucie customer service guide, technicians read both meters, the customer supplies identification and the new service address, and a final bill for the old account is mailed (Residential Customer Service Guide, moving between locations). The New Customers FAQ adds the condition: transfers can be handled over the phone, but every outstanding charge at the old location has to be paid before the transfer is completed (New Customers FAQ, account transfers). The online Transfer Service request covers the same step for customers who prefer a form (Transfer Service request).

The service area is wider than the city itself. The guide says the service area covers all of the City of Port St. Lucie and parts of unincorporated St. Lucie County, spans more than 120 square miles and serves more than 98,000 customers (customer service guide, service area).

Stopping Port St. Lucie water service takes one business day of advance notice, and the customer of record stays responsible for all usage until Connection Support has been told of the change.

The Port St. Lucie guide says an owner who sold the home must provide proof of sale before the account can be closed (Residential Customer Service Guide, request to stop service). A customer leaving the service area schedules a final meter reading; any deposit on record is credited toward the final bill, and a forwarding address is required so the city can mail the final bill or a check for any remaining deposit. The online Stop Service (Move Out) form handles the request (Stop Service (Move Out) request).

Seasonal Port St. Lucie residents have a middle option. The guide lets a customer who travels for extended periods ask to have the meter locked off; the account stays open, the base facility charge keeps billing, and the guide, read October 22, 2026, lists a $50 turn-on fee when service is restored (customer service guide, leaving and returning). After a long absence, the guide recommends running the bathtub for about 5 minutes to flush water that sat in the pipes.

A Port St. Lucie home sold with a recorded Capital Charge Installment Payment Agreement goes through the city's assumption or subordination application, and the utility account must be current before the city processes it.

The Port St. Lucie application page lists a title commitment showing the lender and loan amount, all recorded pages of the installment agreement and any earlier assumption or subordination agreements, and the deed by which the seller took title; LLC closings also provide articles and managing members (Subordination & Assumption Application, City of Port St. Lucie). The page asks for at least 10 business days for routine agreements. Fees as posted on October 22, 2026: $200.00 for a subordination and assumption, $200.00 for an assumption in a cash deal and $50.00 for a subordination on a refinance, all non-refundable; an assumption also needs a lien search from the city's Lien Services Division for an $80 fee (assumption fee schedule as posted).

Port St. Lucie Utility Systems Customer Service and Billing answers at (772) 873-6400, Monday through Friday from 8 a.m. to 5 p.m., and the same number handles emergencies around the clock.

The Port St. Lucie contact page lists utility@cityofpsl.com for billing questions and the same number for maintenance emergencies (Contact Utility Systems, Port St. Lucie). The billing page gives its location as Building A of City Hall at 121 SW Port St. Lucie Blvd., and on the phone menu option 3 reaches a Connection Support Specialist and option 2 reports water and sewer emergencies (Utility Billing & Accounts, contact block and phone menu).

A new Port St. Lucie account cannot be registered online right away: the billing page says new customers wait for the first bill to be generated before creating an online login (Utility Billing & Accounts, online registration). Payment methods and fees after that point are covered in the Digital Towns guide to paying a Port St. Lucie water bill.
