- Maintaining the use of the existing facility during construction of the new one
- Cooperation with existing business and residences that would be affected by the location of the new facility
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.
