The City of Cocoa Water Utility

The City of Cocoa water utility serves over 85,000 accounts across roughly a third of Brevard County, from Cocoa Beach and Merritt Island to Viera and Kennedy Space Center (Cocoa Water Treatment page).

The full list on the city Water Treatment page is the City of Cocoa, Cocoa Beach, the City of Cape Canaveral, Port Canaveral, Sunrise Village, the City of Rockledge, the City of Titusville as a wholesale customer, Cape Canaveral Space Force Station, Kennedy Space Center, Patrick Space Force Base, and the unincorporated communities of Merritt Island, Viera, Suntree, Port St. John and Canaveral Groves (Cocoa Water Treatment page).

Three City of Cocoa documents of different dates give different sizes for the system:

Sources for the table: 2009 work plan, 2022 Annual Water Quality Report and Water Treatment page.

Most of Cocoa's water is groundwater pumped from a wellfield in southeastern Orange County, supplemented by surface water from Taylor Creek Reservoir (Cocoa Water Supply page).

The 2022 report names the Intermediate and Floridan aquifers as the primary source and places Taylor Creek Reservoir three miles from the Claude H. Dyal Water Treatment Plant, where reservoir water is treated and blended with treated groundwater (2022 Annual Water Quality Report; Cocoa Water Supply page). The older work plan explains the inland location: in Brevard County the Floridan Aquifer generally contains brackish water, so Cocoa put its well field in east Orange County; in 2009 that field had 48 wells, 34 drilled 400 to 600 feet into the Floridan Aquifer and 14 into the Intermediate Aquifer (2009 Water Supply Facilities Work Plan). The well count is the 2009 figure; the current Water Supply page lists a Well 17 Replacement project but no total (Cocoa Water Supply page).

Cocoa also keeps 10 aquifer storage and recovery (ASR) wells at the Dyal plant, which store finished, treated water underground for periods of high demand (2022 Annual Water Quality Report). The withdrawals run under a Consumptive Use Permit from the St. Johns River Water Management District that the utility renewed in 2022 for a minimum 20-year period, covering both the aquifer and Taylor Creek Reservoir (2022 Annual Water Quality Report).

Cocoa runs three treatment facilities: the 48 million gallon per day Wewahootee pretreatment plant, the 60 mgd Dyal groundwater plant and the 12 mgd Dyal surface water plant (Cocoa Water Treatment page).

Groundwater entering the Cocoa Dyal plant gets chlorine, lime, soda ash and coagulant to remove hardness and suspended solids, carbon dioxide to lower pH, and chloramination after passing through sand and anthracite filters (2022 Annual Water Quality Report). Surface water from the reservoir is treated with ferric sulfate, hydrated lime and a polymer, then ozone for disinfection and taste and odor removal; that surface water plant came online in October 1999, and the report calls Dyal unusual for Central Florida because it treats both kinds of water (2022 Annual Water Quality Report).

The 2022 report gives the most recent volumes read for this page: the system processed just over 6.89 billion gallons in 2022, with a peak flow of 23.50 million gallons per day in May and an average of 18.88 MGD; the Dyal plant treated 6.71 billion gallons of groundwater and 180.29 million gallons of surface water (2022 Annual Water Quality Report). Cocoa has supplied central Brevard County since 1957, per the same report.

Cocoa normally disinfects with chloramine but periodically switches to free chlorine for a temporary period, which can change the taste and smell (City of Cocoa FAQ).

The city FAQ describes the switch: during the first two weeks and last two weeks the water moves between chloramine and free chlorine, and during the middle six weeks it should carry free chlorine only (City of Cocoa FAQ). The FAQ says only fish, amphibian and reptile owners and dialysis patients need to take special precautions, and points aquarium owners, restaurants with holding tanks and dialysis users to an appropriate professional for guidance (City of Cocoa FAQ).

For people sensitive to the taste, the FAQ suggests leaving water in a container in the refrigerator for a few hours, and asks customers concerned about a change in color to contact the Utilities Department (City of Cocoa FAQ), which is at 351 Shearer Blvd., (321) 433-8700 (Cocoa Water Treatment page). The FAQ gives no dates for a switch, and this page does not list them.

Cocoa posts an annual water quality report online, and the newest one, the 2025 report, went up on May 28, 2026 with test results from the 2025 calendar year (Cocoa news release).

The city Annual Water Quality Reports page lists the 2018 through 2025 reports (Cocoa Water Quality Reports page). From 1999 until 2013 Cocoa mailed the report to every billing customer; after EPA guidance in early 2013 allowed electronic delivery, the city switched to an online version (Cocoa Water Quality Reports page). The city said it would print the report link on water bills in June 2026, and a paper copy can be requested from UtilWaterQuality@cocoafl.gov or 321-433-8705 (Cocoa news release).

The 2022 edition, the latest one read in full for this page, says the Cocoa water lab runs over ten thousand chemical and bacteriological tests a year for more than 135 regulated and unregulated substances, and that a 2022 Florida Department of Environmental Protection source water assessment found 27 unique potential sources of contamination with a range of low to moderate risk (2022 Annual Water Quality Report). Readers who want current test tables should open the 2025 report from the reports page rather than rely on the 2022 figures.

The city lists eight water treatment projects and two water supply projects, and routes billing questions and main breaks to (321) 433-8400 (Cocoa Water Treatment page; Cocoa Water Supply page).

The treatment list covers Chemical Conversion and Reliability Improvements, a Water Capital Plan Update, Replacement of the Dyal Finished Water Steel GST, Groundwater Treatment Filters Rehabilitation (Filter 3), Viera Pump Station Chlorination Improvements, Ozone System Improvements, the Banana River Tank Improvement Project and Clarifiers Rehabilitation (Cocoa Water Treatment page). The supply list adds Well 17 Replacement and Taylor Creek Pump Station Improvements (Cocoa Water Supply page).

Water Customer Service is at 65 Stone St. and (321) 433-8400, which is also the number to report a water, sewer or reclaimed main break; the Utilities Department is at 351 Shearer Blvd., (321) 433-8700 (Cocoa Water Treatment page). Paying a bill, deposits and starting or stopping service are covered in the Cocoa water bill and payments guide.

Last verified: October 21, 2026, when the Cocoa Water Treatment, Water Supply and Water Quality Reports pages, the May 2026 report notice, the 2022 report, the 2009 work plan and the disinfection FAQ were each fetched again.
