Many factors in treatment plant equation

Water use, infiltration and average flow, number of lagoons, nitrogen and E. coli, grants, debt service fee. These concepts all flow into the equation of the Allison wastewater treatment plant.
The current Allison wastewater treatment plant was designed for an average wet weather flow of 200,000 gallons a day. There are two 7.5-acre cells in the lagoon, which was constructed in 1966.
The city water superintendent said, in a Sept. 10, 2015, archived story, that current high wet weather flow after a big rainstorm was 800,000 gallons a day.
