Cooling Towers

Get rebates for making Water Wise choices.

Up to $1,000 rebate available.

Cooling towers are used in commercial buildings to remove the heat generated by computers, lights, people, and more. This process of removing heat requires a significant amount of water. As part of an effort to reduce potable water use, Tampa Bay Water Wise is offering rebates for businesses that increase the cycles of concentration (COC) for their cooling tower from less than 3 to at least 6 COC’s or more. This increase in the cycles of concentration can benefit public health by reducing potential contamination (ex: legionella), and it will save water.

Eligibility Requirements

  • Applicant must be an existing potable water utility customer of the city of St. Petersburg, city of New Port Richey, Pinellas County, Pasco County or Hillsborough County.
  • Existing property must be using an operable, potable water-based cooling tower with at least a 500-ton capacity, and with current COC at 3 or less.
  • Applications for a cooling tower rebate must be submitted directly to Tampa Bay Water Wise. To initiate the rebate application process, please contact Tampa Bay Water Demand Management at (727) 791-2323.
  • Tampa Bay Water Wise will determine eligibility within 30 days of receipt of completed application. After each submission Tampa Bay Water Wise will have 30 days to determine if the application meets eligibility requirements. Up to 3 modifications to the application information will be allowed.
  • Applicants need to accurately create a baseline of cooling tower water use for example:
    • • estimates of cooling tower water use based on cooling load, if available; or,
    • • correctly sized total metered water use for cooling tower, metered make up, blowdown, and overflow uses with at least 12 months of historical water use data (for the building, or cooling tower if it was individually metered).
  • Applicants need to provide a brief explanation of what the anticipated COC’s will be and the anticipated savings.
  • If the applicant is installing a new cooling tower, anticipated water use changes will need to be explained and COC will need to be at least 6.
  • Applicants may identify and propose installation of new technologies or changes in treatment processes to reach at least 6 COC.
  • Program operational requirements for cooling tower unit owners/operators shall include the following (which will be visually verified by Tampa Bay Water Wise following installation). At a minimum:
    • • Units shall have at least 3 impulse water submeters on them to measure: cooling tower incoming water, makeup water, and overflow. This could be connected to an existing programmable logic controller (PLC).
    • • Receipts for meters and installation are required. If a PLC is installed it can be part of the reimbursable cost ONLY if the cost of the submeters, conductivity sensor and controller have not exceeded the rebate total. A PLC cannot be installed in lieu of these items.
    • • Units shall have a conductivity sensor and controller installed for conductivity monitoring. This could be installed on an existing PLC. Receipts for the conductivity sensor and controller (including installation) are required to be submitted.
    • • If COC decline to less than 6, the owner will provide a written remediation strategy to ensure COC are increased or funds will need to be returned to Tampa Bay Water Wise (sliding scale of 100% of rebate returned at time zero, to 0% of rebate returned at 24 months). Tampa Bay Water Wise will work with the owner to remediate.
  • Independent, third party verification of technology/treatment process water efficiency potential is required to be eligible for the rebate. Tampa Bay Water Wise will have a list of eligible products. Independent third party verification will be determined on a case by case basis. Tampa Bay Water Wise will create a list of technologies previously approved for use in the region.
