|Timpanogos Special Service Plant Expansion -
In 1995, Horrocks Engineers, together with Carollo Engineers, designed the 1996 Plant Expansion
project which included an inlet splitter box, headworks, four oxidation ditches, clarifiers, and drying beds.
In addition, the expansion included significant modifications to the plant dissinfection system, including a
sodium hypochlorite generator and a high pressure UV reactor. During the design of the facilities, it was
determined that the County would require the complete reconstruction of the existing chlorination facilities.
The chlorine contact basins were replaced with an ultra violet reactor. However, to maintain minimum algae levels
within the plant, chlorine was needed. Therefore, a sodium hypochlorite generating system was designed and constructed.
The treatment plant expansion was completed ahead of schedule and under budget.
