Wastewater Treatment Facility (SBR)

DGR Engineering (DGR) worked jointly with the City to evaluate multiple treatment alternatives which included updating the existing wastewater treatment plant. Ultimately, the selection of sequencing batch reactor (SBR) was made, based on cost, operational flexibility and convenience. The option of modernizing the existing plant was rejected because the cost would have been nearly double that of a new facility.

The new plant, rated for 5.3 million gallons per day (MGD) peak day, doubles the capacity of its predecessor. It is adequate for future population growth as well as economical development with industrial growth potential.

Wastewater Treatment Facility (SBR)

The new SBR system utilizes the existing aeration lagoon for equalization and another lagoon cell for sludge storage, which reduced the cost of the project for the City and provided more operational flexibility.
