Water Reclamation Division

Treatment of wastewater (sewage) is an essential service for a densely populated area such as the City of Casselberry. The wastewater treatment facility, also known as the Water Reclamation Facility, is permitted to treat 2.20 million gallons per day (mgd).

The wastewater treatment process consists of:

  • Screening and grit removal to remove solids (primary treatment)
  • Biological (secondary) treatment in an aerated tank
  • Settling out of the biological solids
  • Filtration of the liquid portion (tertiary treatment)
  • High level of disinfection
  • The biological solids (sludge or residuals) are thickened and provided with further treatment to stabilize them for land application.  The facility produces an average of 1.2 - 1.4 mgd of reclaimed water.

The City of Casselberry Water Reclamation Facility is classified as 100% reuse, meaning that all treated wastewater is reused. Reclaimed water meets or exceeds the standards set forth in both the State and Federal Regulations.

Because of this high level of treatment, the "reclaimed water" may be used for irrigation of areas where the public has access. Water that does not meet that high level of treatment is sent to restricted access rapid infiltration basins. These basins are also known as percolation ponds because the water percolates into the ground to recharge the aquifer.


The City has expanded the Water Reclamation Facility to provide the customer with more reclaimed water. In January 2001, the City added a new filtration system, which increased the filtration capacity of 2.5 mgd for a total treatment capacity of 2.20 mgd of reuse water. A second storage tank also was added for a total storage capacity of three million gallons. The City has recently completed expanding the reclaimed water distribution system to other neighborhoods within the City. In 2004, the City was awarded First Place Reclaimed Water Plant for the state of Florida by the Florida Water Environment Association.


The Code of Federal Regulations (CFR) and the Florida Department of Environmental Protection (FDEP) requires pre-treatment of commercial and industrial wastes to reduce pollutants which can pass through or interfere with the wastewater treatment process.

The City has adopted an industrial/commercial pre-treatment ordinance requiring identification of pre-treatment requirements and possible permitting. Wastewater Discharge Permits are issued by the City's Environmental Coordinator.
