Fiscal Responsibility

Tampa Bay Water is committed to providing safe, clean drinking water at an affordable price, and in 2018 the wholesale uniform rate remained at $2.56 per 1,000 gallons for the eighth year. The utility continues to earn outstanding bond ratings, maintaining an AA+ from both Standard & Poor’s and Fitch, and Aa1 rating from Moody’s. These ratings are a testament to the financial stability of Tampa Bay Water and allow the utility to issue bonds at lower interest rates, potentially saving ratepayers millions over time.

Tampa Bay Water keeps water affordable through its budgeting process. As a special district of the State of Florida, we are funded through the sale of wholesale water to the local governments we serve. We have no taxing authority and we do not make a profit.

Long-term Master Water Plan Update Approved in 2018

This past year, Tampa Bay Water passed an important milestone for future water supply – the completion and approval of the 2018 update of the Long-term Master Water Plan; the agency's fourth update to the plan since it was created in 1998. The Long-term Master Water Plan is the region’s road map for future water supply, and its approval completes five years of comprehensive analyses of supply, demand, system hydraulics, water quality, reliability and public engagement.

The plan forecasts that the region will need an additional 10 million gallons of drinking water per day by 2028 and another 10 million gallons per day in 2038. Most importantly, it also identifies that Tampa Bay Water has several options to meet the region’s future needs, and time to investigate the best solutions.

The 2018 Plan Includes:

Conserving up to
million gallons per day
through regional demand
Studying options
to optimize the existing
surface water treatment
plant and desalination plant
to gain
million gallons per day of additional supply
potential new projects
to refine cost, yield and permittability
The three potential new supply projects approved for continued study are:

  • Tampa Bay Regional Surface Water Treatment Plant Expansion (to treat additional water from the Tampa Bypass Canal, Alafia River and C.W. Bill Young Regional Reservoir)
  • Tampa Bay Seawater Desalination Plant Expansion (to treat additional seawater from Tampa Bay)
  • New Groundwater via Aquifer Recharge Credits (this project would include a new groundwater wellfield in southern Hillsborough County by purchasing aquifer recharge credits from Hillsborough County via its South Hillsborough Aquifer Recharge Project)

Tampa Bay Water is studying potential projects to refine cost, yield and permittability for future board consideration. Additionally, Tampa Bay Water continues to work with Hillsborough County on meeting the growing demands for drinking water in southern Hillsborough County.
