The New Hampshire Department of Environmental Services approves all septic systems in the state. As part of the review and approval process, they will send a "local approval form" to be completed by Goffstown Staff.
Please send your septic design plan and local approval form to Email Septic System Turnaround time for these reviews can vary depending on staff availability, but we are usually able to turn them around within 3-5 business days.
Goffstown is an MS4 community. This means our storm drain discharge is regulated by the EPA. When septic systems back up and overflow, they can enter the drainage system or directly enter local waterbodies contributing to bacteria impairment. You can do your part to keep Goffstown surface water bodies clean by getting your septic systems pumped and inspected every 1 to 2 years.
