Water Service in Tampa — Tampa, Florida

Water service in Tampa operates through two distinct but interconnected entities. The City of Tampa Water Department functions as the retail utility, distributing drinking water, collecting wastewater, and supplying reclaimed water to customers within city limits and adjacent areas. Above that layer, Tampa Bay Water acts as the regional wholesale authority, treating and delivering finished water in bulk to Tampa and five other member governments across Hillsborough, Pinellas, and Pasco counties.

According to the U.S. Census Bureau ACS 2023, Tampa has a population of 393,389 spread across approximately 160,527 households, nearly equally split between owner-occupied and renter-occupied units. That residential composition — combined with a 15.9 percent poverty rate — shapes the policy context within which the City of Tampa Utilities Department administers drinking water, wastewater, reclaimed water, and solid waste services. Tampa Bay Water's 2024 Year in Review documents delivery of nearly 200 million gallons of clean drinking water per day to its six member governments and their customers in 2024.

The City of Tampa Utilities Department administers retail drinking water distribution, wastewater collection, reclaimed water, and solid waste services. Its water and wastewater service areas extend beyond city limits into portions of unincorporated Hillsborough County and the City of Temple Terrace, according to the City of Tampa Utilities portal. Solid waste collection, by contrast, is limited to city residents south of Fowler Avenue, excluding the New Tampa and University areas.

Tampa Bay Water is the regional wholesale supplier whose six member governments are the cities of Tampa, St. Petersburg, and New Port Richey, and the counties of Hillsborough, Pinellas, and Pasco. The authority was formed under Florida law to coordinate water resources across those three counties, replacing an earlier multi-county agreement. It draws from a portfolio of sources: groundwater wellfields, the Alafia River, the Hillsborough River, the Tampa Bypass Canal, and Tampa Bay itself via a seawater desalination facility. Tampa Bay Water's board of directors represents its member governments and governs major capital commitments; the February 2025 board approval of the South Hillsborough Pipeline joint project agreement amendment illustrates that governance structure.

Residential customers with account and service-address inquiries can contact the City of Tampa Utilities Call Center at (813) 274-8811, per the department's published contact information.

Tampa Bay Water operates a diversified portfolio of water supply sources to serve the Tampa Bay region. The Tampa Bay Seawater Desalination Plant, located in the Port of Tampa area, is one of the earliest large-scale seawater desalination facilities in the United States. Tampa Bay Water describes it as a drought-proof, alternative water supply capable of producing up to 25 million gallons per day — representing up to 10 percent of the region's drinking water needs. The facility employs a multi-stage pretreatment sequence — including coagulation, flocculation, sand filtration, diatomaceous earth filtration, and cartridge filtration — before the water passes through reverse osmosis membranes.

Surface water sources include the Alafia River, the Hillsborough River, and the Tampa Bypass Canal. The authority's 2025 Year in Review reports that a $181 million expansion of the Regional Surface Water Treatment Plant was among three major active infrastructure projects, alongside the South Hillsborough Pipeline and the South Hillsborough Wellfield.

At the retail level, the Howard F. Curren Advanced Wastewater Treatment Plant, situated in the Port of Tampa area, serves as Tampa's primary wastewater treatment and reclaimed water production facility. Reclaimed water — distributed through purple-pipe infrastructure — is available in Davis Island and parts of South Tampa, providing treated and disinfected wastewater effluent for landscape irrigation and reducing demand on the potable supply, according to the City of Tampa's reclaimed water program page.

Looking further ahead, Tampa Bay Water's future supply planning page identifies options under evaluation including desalination plant expansion feasibility, the Eastern Pasco Wellfield, and a South Hillsborough Surface Water Treatment Plant and Reservoir.

The City of Tampa Utilities bills residential customers on a tiered rate schedule that is updated annually on October 1. Under the FY2026 rate schedule, effective October 1, 2025 through September 30, 2026, the monthly base charge for inside-city residential customers is $8.00 each for water service, wastewater service, and irrigation service. Reclaimed water is billed at $1.20 per ccf (748 gallons), according to the City of Tampa Utilities rates page.

At the wholesale level, Tampa Bay Water's 2025 Year in Review states that the authority maintained a wholesale rate of $2.62 per thousand gallons in 2025, supported by efficient operations and strategic financing. The authority also reported that seven completed capital projects in 2025 came in a combined $5.3 million under budget.

Customers interested in reclaimed water service can also arrange bulk purchases directly at the Howard F. Curren Advanced Wastewater Treatment Plant, per the City of Tampa's reclaimed water program documentation.

Water quality monitoring in Tampa operates at both the regional wholesale and retail levels. According to Tampa Bay Water's 2025 Year in Review, the authority performs more than 62,000 laboratory tests annually and maintains hundreds of regional water quality monitoring sites. The authority also publishes its own annual water quality report, with monitoring and testing governed by EPA and Florida Department of Environmental Protection (FDEP) requirements.

At the retail level, the City of Tampa Water Department publishes an annual Consumer Confidence Report (CCR) in compliance with the federal Safe Drinking Water Act, with Florida's statutory publication deadline set at July 1 each year. The CCR is made available in both English and Spanish.

Regarding per- and polyfluoroalkyl substances (PFAS), Tampa Bay Water's 2024 Water Quality Report documents that the EPA issued PFAS regulations in April 2024 establishing a maximum contaminant level of 4.0 parts per trillion for PFOA and PFOS, with full compliance required by 2029. The authority conducted PFAS monitoring under the EPA's Unregulated Contaminant Monitoring Rule 5 (UCMR 5) program during the 2023–2025 period.

Also in 2025, pursuant to a new Florida state law, the Tampa Water Department discontinued the addition of fluoride to the city's drinking water supply, as documented on the Tampa Water Department's annual water quality report page.

The most consequential near-term infrastructure project is the South Hillsborough Pipeline, a 26-mile, two-segment transmission main with a diameter of up to 60 inches and a total capital cost of $505.7 million. When completed — targeted for late 2028 — the pipeline is designed to deliver up to 65 million gallons per day to southern Hillsborough County. In February 2025, Tampa Bay Water's board approved a restated joint project agreement to accommodate additional infrastructure, including a future county point-of-connection tee near Riverview and yard piping at the Lithia Water Treatment Plant. The Hillsborough County Board of County Commissioners approved its side of that agreement on February 19, 2025.

Separately, a water shortage declaration affected Tampa in early 2026: the Southwest Florida Water Management District (SWFWMD) issued a Modified Phase III Extreme Water Shortage Order — the highest level — effective April 3, 2026, according to the City of Tampa Utilities portal. That order followed a Modified Phase 2 declaration in January 2026 and a drought conservation notice issued in March 2026 by the City of Tampa Water Department. Also in 2025, Tampa Bay Water's Year in Review documents that the $181 million expansion of the Regional Surface Water Treatment Plant and the South Hillsborough Wellfield project were both actively under construction.

Outdoor irrigation in Tampa is subject to mandatory once-a-week watering restrictions enforced year-round under SWFWMD rules, according to the City of Tampa Utilities portal. During declared water shortage phases, SWFWMD layers additional restrictions on top of that baseline. Under the Modified Phase III Extreme Water Shortage Order in effect as of April 3, 2026, outdoor irrigation using potable water is prohibited between 4 a.m. and 8 p.m., and decorative or aesthetic fountain operation is limited to four hours per day.

Customers served by Tampa's reclaimed water system occupy a different regulatory position: they are not subject to the mandatory once-a-week potable-water watering restrictions, though they remain subject to time-of-day restrictions during severe drought orders, per the City of Tampa's reclaimed water program page. The reclaimed water system — distributed through purple-pipe infrastructure in Davis Island and parts of South Tampa — supplies treated wastewater effluent that meets strict quality requirements set by the Florida Department of Environmental Protection. By shifting landscape irrigation demand away from potable supplies, the system is documented as a tool for reducing regional freshwater withdrawals.
