Transition to ePermitting
DHEC is now offering an online option for Septic Tank permit applications through our ePermitting system. ePermitting streamlines the application process, allows you real-time access to your application status and associated permitting information, and provides 24-hour access to your account. For customers who are unable to access ePermitting, we will continue to accept traditional paper applications. Questions? Contact our customer service team at 1-855-731-2504 or by email at OSWWCentral@dhec.sc.gov.
