County Wastewater Treatment Capacity

For each community with a population greater than 100, existing design treatment capacity and average daily uses were collected. Growth projections established a 10-year growth capacity. The delta between current installed capacity and 10-year projected growth established an excess or deficient capacity in treatment. The data is meant to highlight that growth is inevitable and the need for additional wastewater treatment capacity is inevitable.
