Charleston Water System requires any work on our water distribution and wastewater collection systems to be performed by an approved contractor.

There are two categories of approved contractors: those approved for large projects ($50,000 - $300,000), and those approved for small projects (under $50,000). Please note that some contractors are approved for both small and large projects. Click the links below to download the lists.
