Industrial Pretreatment Program

The primary goals of the Industrial Pretreatment Program include the following:

  • Protecting the health and safety of the community and city workers
  • Prevent discharges to Wastewater Facilities, which will interfere with the operation of the facilities including interference with the use or disposal of wastewater residuals.
  • Prevent discharges to the Wastewater Facilities which will pass through or otherwise be incompatible with treatment facilities
  • To improve opportunities to beneficially use domestic wastewater residuals (reclaimed water and sludge)

Industrial Pretreatment services all three of Clearwater's Advanced Wastewater Treatment Facilities. This includes all non-domestic discharges in the Cities of Clearwater and Safety Harbor.

According to the Florida Administrative Code (62-625), Public Utilities are required to develop a pretreatment program for:

  • Any wastewater facility (WWF) or combination of WWF's operated by the same public utility with a total design flow greater than 5 million gallons per day (MGD) and receives pollutants from industrial users
  • Any WWF providing reclaimed water to public access facilities
  • Any WWF identified as needing a pretreatment program by FDEP

Industrial Pretreatment Ordinance:

The City of Clearwater approved a revised sewer use Ordinance #6393-99 on August 5, 1999 and was revised by Ordinance #6828-01 on August 16, 2001. Ordinance #8322-13 was passed by City Council on February 21, 2013 and received final approval by the Florida Department of Environmental Protection March 31, 2014. The ordinance provides:

Clearwater's Pretreatment Program is responsible to act as the "control authority" in the infrastructure including the sanitary collection systems and wastewater treatment plants by:

  • Preventing discharges that may interfere with operation and disposal of wastewater (effluent) and/or sludge
  • Preventing discharges which will pass through or be incompatible with treatment
  • Improving opportunities to beneficially use wastewater residuals and reclaimed water

Industrial Users:

The sewer use ordinance and local limits apply to all industrial customers who discharge into Clearwater's sanitary sewer system. The City of Safety Harbor ( discharges sewerage into the Northeast Advanced Wastewater Treatment Facility. The City of Clearwater has an inter-local agreement with Safety Harbor. Safety Harbor has approved a sewer use ordinance in conjunction with Clearwater on November 15, 1999. Once Ordinance #8322-13 is approved by FDEP, Safety Harbor will be required to adopt a new ordinance that mirrors that of the City of Clearwater.
