Dorchester Plans to Double Capacity of N Chas Wastewater Treatment Plant to Accommodate Growth

Dorchester County is expanding its lower wastewater treatment plant to keep pace with the rapid growth of the Summerville area, with projections suggesting that the number of residents in the county will exceed 200,000 by 2030.

The expansion of the North Charleston plant will allow it to double the amount of wastewater it treats, from 8 million gallons per day to 16 million. The plant serves the greater Summerville area, East Edisto, Ridgeville, Knightsville, Jedburg, and Ladson.

The entire project is expected to cost about $199 million, with a $65 million bond to pay for the first two phases of the expansion. The first phase should be completed by 2025, allowing the plant to treat up to 10 million gallons per day, and the entire expansion is expected to be finished by December 2027.

The treatment plant is critical for the county's economic growth, as it provides the only source of wastewater treatment for industry in that specific region of the county.
