The Southwest Regional Water Reclamation Facility (SWRWRF) is an existing wastewater treatment facility (WWTF) owned and operated by Citrus County approximately three miles east of the Chassahowitzka River, which has been designated an Outstanding Florida Waterway.
The Chassahowitzka River flows to the Gulf of Mexico and is formed from pristine waters contributed by more than 12 springs.
The project, with construction on schedule, includes the planning, permitting, design and construction of an advanced wastewater treatment facility to provide tertiary treatment with nitrogen removal and the production of high-quality reclaimed water for irrigation of public-access areas. Once operational, the new facility will reduce nitrogen loading to groundwater and offset the need for groundwater withdrawals for irrigation purposes.
The current facility will be replaced by a new 1.5 million gallons per day (mgd) annual average daily flow, 4-stage Biological Nutrient Removal (BNR) oxidation ditch system followed by secondary clarifiers, disc filters, and chlorine disinfection, with reclaimed water disposed to rapid infiltration basins on the plant site and to the County’s public access reuse. BNR is a process used for nitrogen and phosphorus removal from wastewater before it is discharged.
This cornerstone project is part of a larger and continuing effort to protect our water in Citrus County by removing unwanted nutrients, reducing groundwater pumping and providing capacity for future septic to sewer projects now and in the future. This is a project of Citrus County Water Resources Department led by Director Ken Cheek, the Engineering firm is Jones Edmunds & Associates, Inc. and the project contractor is Wharton Smith, Inc.
The new facility is slated to be completed and operational by summer 2020.
