Saving Water, Saving Money
Conserving water before tapping new sources saves money, saves energy and protects our environment. While the Tampa Bay region has successfully conserved water over the past 20 years, there are still opportunities for improvement.
Tampa Bay Water’s regional demand management program, Tampa Bay Water Wise, includes several elements that can save an estimated 6 million gallons per day by 2025 and up to 11 million gallons per day by 2030 at less than a quarter of the cost of the least expensive new water supply alternative. The savings can be achieved if all member governments participate in the program, which includes a mix of rebates and incentives for single-family homes, multi-family homes, new housing developments and commercial and industrial properties.
Tampa Bay Water Wise was developed collaboratively with Tampa Bay Water’s member governments. To make the program even more cost-effective, the program is co-funded by the Southwest Florida Water Management District.
Upgrading Facilities to Improve Yields
Tampa Bay Water can also maximize existing supplies by upgrading two existing facilities: the Tampa Bay Regional Surface Water Treatment Plant and Tampa Bay Seawater Desalination Plant. Preliminary engineering analyses show that the Regional Surface Water Treatment Plant could possibly produce another 5 million gallons of per day by modifying the facility’s filtration system operations.
Likewise, the Seawater Desalination Plant could be upgraded to improve performance and reliability to possibly produce additional water. A key upgrade for the Seawater Desalination Plant is the eventual replacement of the pretreatment system with a more reliable and high-performing technology. By reducing downtime for maintenance and improving operations, the facility’s annual production could be increased.
In 2019, Tampa Bay Water hired consulting engineers to conduct more thorough preliminary design and analyses for the optimization projects, including:
- Conducting demonstration studies to confirm that operational changes at the Regional Surface Water Treatment Plant will increase sustainable yield.
- Pilot-scale testing of alternative pretreatment systems and membranes at the Seawater Desalination Plant to improve reliability and sustainable yield.
- Evaluating potential improvements at the Seawater Desalination Plant to address
future TECO operational changes.
The Regional Demand Management Program was launched in early 2020. Residential and commercial property owners can check their eligibility at TampaBayWaterWise.org.
Tampa Bay Water conducted focus groups, public opinion surveys, telephone town halls and speaker’s bureau presentations to obtain input used in the Long-term Master Water Plan. Public outreach will continue for those projects selected for continued evaluation.
Long-term Master Water Plan
Regional demand management and facility optimization were identified in Tampa Bay Water’s 2018 Long-term Master Water Plan as two cost-effective ways to defer the need for new supply development. This 20-year framework for meeting the region’s future drinking water needs includes analyses of future demand, conservation potential, supply reliability, water shortage mitigation planning, and hydrologic uncertainty along with potential water supply projects to ensure adequate drinking water in the future.
