Septic System Codes

A certified septic designer must design the system. Test pits must be witnessed by the Durham Building/Health Inspector. The Town fee is $100.00. One large copy of the designed drawings must be submitted to the Town Code Officer with the required State Approval form for review. The Code Office will approve, sign and email the State Approval form back to the designer to be sent to the State.
