Septic Systems: Approval for Operation

Once an approved septic system is installed, DES will inspect the newly-constructed system. The septic system must be installed by an individual permitted to do so by DES, unless an individual homeowner does the work for his/her own home. Prior to using a septic system, both an Approval for Construction and an Approval for Operation must be obtained.

Purpose
To prevent pollution of all public or private water supplies, whether underground or surface sources. Subsurface sewage disposal (septic systems) must be designed, installed, operated, and maintained properly to ensure adequate protection of public health and the environment.

Applicability
A DES inspector will inspect the newly-constructed septic system and evaluate the system to ensure that it has been installed in accordance with the intent of the approved plan. Once the inspector has determined that the system meets all applicable requirements, a written Approval for Septic System Operation will be completed, with a copy provided to the owner, municipality, and DES.
