City of Alta Wastewater Treatment Plant

To meet water quality requirements, the City sought ISG to perform an in-depth evaluation of the City’s existing trickling filter wastewater treatment system. Our team recommended the construction of a new activated sludge system that combines aeration tanks, clarifier tanks, and digester tanks into one unitized and innovative system. The new treatment system showed substantial improvements over the existing, is energy-efficient, has a smaller footprint compared to other activated sludge designs, and has a lowered capital cost.
