Current Capital Improvements Program

Our 2019 - 2022 Capital Improvements Program was approved by our Board of Commissioners Nov. 15, 2018.

It includes 24 critical water and sewer infrastructure projects that will allow us to accommodate growth in our service area, rehabilitate or replace aging infrastructure, and continue to meet changing regulatory requirements.


Projects in this Capital Improvements Program include:

  • Establishing a third point of delivery to Mount Pleasant Waterworks via construction of a new water main beneath the Intracoastal Waterway
  • New facilities at the Plum Island Wastewater Treatment Plant to provide additional treatment capacity
  • Construction of a new administrative building near the Hanahan Water Treatment Plant to house Customer Service and IT.
