Water Service in Melbourne, Florida

Melbourne tap water is a blend of treated Lake Washington water from the Buckley surface water plant and treated Floridan Aquifer water from the Joe Mullins reverse osmosis plant.

Buckley plant intake water comes out of Lake Washington; the city ranks that lake third uppermost among the naturally connected upper St. Johns River lakes and calls it one of the few Florida lakes used as a drinking water supply (City of Melbourne, Water Treatment and Distribution). The St. Johns River Water Management District puts that in regional terms: across its 18 counties, only two surface water bodies supplement underground supplies, Taylor Creek Reservoir for Cocoa and Lake Washington for Melbourne (SJRWMD). A fixed crest weir just north of Lake Washington is the single point where the district regulates river flow to help ensure water supply to Melbourne (SJRWMD, River Lakes Conservation Area).

At the Buckley plant, Lake Washington water goes through the Actiflo process. Chloramines, made by adding ammonia to chlorine, are the disinfectant, and ozone is used to reduce the potential for disinfection byproducts (2026 Annual Drinking Water Quality Report).

The Melbourne Mullins plant went into service in 1995, built for 5 million gallons per day with a 4 million gallon ground storage tank. It pulls brackish water from four Floridan Aquifer wells about 650 to 850 feet underground, each yielding approximately 3.1 million gallons per day (City of Melbourne). Reverse osmosis removes salt and impurities, the treated groundwater is blended with the treated lake water, and chloramine booster stations along the Melbourne mains keep disinfection levels up (2026 report).

Beyond the city itself, Melbourne water goes to Melbourne Beach, Indialantic, Indian Harbour Beach, Satellite Beach, Palm Shores, Melbourne Village and unincorporated Brevard County south of the Pineda Causeway, plus wholesale water service to West Melbourne (City of Melbourne).

That reach explains why a beachside address in Satellite Beach or Indialantic gets a Melbourne water quality report even though its town hall is elsewhere. West Melbourne is a different case, because the city describes its supply to West Melbourne as wholesale water service. The district article describes the whole territory as a 100 square mile water service area (SJRWMD).

The number of people served depends on which document is read. The 2026 Annual Drinking Water Quality Report says approximately 168,000 consumers (2026 report). The SJRWMD upper basin article says Melbourne distributes treated water to a population of roughly 182,000 (SJRWMD). Neither document reconciles the two, so both figures are given here with their source rather than one chosen.

Melbourne holds a permitted production capacity of 25 million gallons per day, while typical daily demand is about 16 million gallons per day, according to the 2026 report covering 2025 (2026 Annual Drinking Water Quality Report).

The 18 million gallon figure from the water management district describes how much lake water can go into the blend, not total production (SJRWMD).

Water that sits too long at the end of a dead-end Melbourne main loses quality, so roughly 100 automatic flushing valves release water every other day for 30 minutes, usually between midnight and 2:30 a.m. (City of Melbourne, Automatic Flushing Valves). A valve running at night in a quiet Palm Shores or Melbourne Village street is routine maintenance, not a leak.

The 2026 Melbourne Annual Drinking Water Quality Report covers 2025 samples and lists one violation, an MCL violation for Escherichia coli bacteria with sampling dates of 4/25 and 5/25 (2026 report).

Every other result in the Melbourne report is marked N for violation or action level exceeded. The E. coli row lists 2 as the total number of positive samples for the year, an MCLG of 0, and as the MCL: routine and repeat samples are total coliform positive and either is E. coli positive. The report explains the result in one sentence: the city had an E. coli positive repeat sample following a total coliform positive routine sample. It says the city was required to complete a Level 2 assessment and to take one corrective action, and completed one. The Level 2 assessment was overseen by a third party and, after a thorough investigation, found no known issues with the water distribution system nor water treatment facilities; chlorine residuals met and exceeded minimum requirements at the location of detection and throughout the distribution system, and a dedicated sampling station was installed to improve sampling techniques and sample processing (2026 report).

All figures in that table come from the 2026 report (City of Melbourne). The lead and copper rows are from August 2023 tap sampling, so they are the oldest data in the report, and no Melbourne site exceeded either action level. The service line inventory itself has its own Melbourne lead and copper program guide.

The same report says the Florida Department of Environmental Protection performed a Source Water Assessment on the Melbourne system in 2025 and identified 4 potential sources of contamination in the vicinity of its groundwater wells and surface water intakes, all with low susceptibility levels (2026 report). Raw lab results go to FDEP and can be searched in its OCULUS database under Melbourne Facility-Site ID 3051447 (City of Melbourne, Water Quality).

Melbourne water service starts with the online Application for Water Service, which the city answers within two working days (City of Melbourne).

Paper forms are in the Melbourne City Hall lobby at 900 East Strawbridge Avenue from 8:30 a.m. to 4:30 p.m. (City of Melbourne, Open a New Account).

The application asks for the customer full name, the service address, a driver license or ID, and a lease or proof of ownership. A $20 service initiation fee appears on the first Melbourne bill, and the deposit may be billed there too for customers without outstanding balances (City of Melbourne).

The posted residential water charge inside Melbourne is a $12.02 monthly base rate plus $6.87 per 1,000 gallons; customers outside the city limits pay $13.22 and $7.56. The water deposit is $60, and new connections carry a $2,755 water impact fee and a $250 connect fee (City of Melbourne, Rate Table). The rate table shows no effective date, so a bill that does not match it is worth checking with Utility Billing at 321-608-7100 (2026 report). Payment options, late notices and assistance programs are covered in the Melbourne utility billing and rates guide.

A broken Melbourne water line, a reclaimed water leak or a sewer backup goes to 321-608-5130 on weekdays and to 321-255-4622 after hours (City of Melbourne, Report a Water Line Break).

The two Melbourne pages give slightly different weekday hours for that line. The line break page says Monday to Friday, 7:30 a.m. to 4 p.m. (City of Melbourne), while the Water Quality page lists the Utilities Operations Division at 321-608-5130 from 7:25 a.m. to 3:55 p.m. for dirty water or quality concerns (City of Melbourne, Water Quality). Calling the after hours number just outside that window is the safe choice.

Other Melbourne numbers printed in the 2026 report: Water Production 321-608-5700, Water and Wastewater Operations 321-608-5100, and 321-608-5080 for a mailed copy of the report, which is also kept at City Hall and at the public libraries in the water service area (2026 report). Questions about a flushing valve go to 321-608-5150 (City of Melbourne). Boil water notices, backflow testing and reclaimed water each have a separate Melbourne utilities guide.
