Septic Services in New Hampshire

Septic systems in New Hampshire are regulated by the New Hampshire Department of Environmental Quality. Homeowners are responsible for maintaining their systems and ensuring compliance with state and local permit requirements. Regular pumping every 3–5 years is recommended depending on household size and system type.

Before installing a new system or making significant repairs, you'll typically need to obtain a permit from your county health department. Soil type, lot size, and proximity to water sources all affect which system types are approved in your area.

Many New Hampshire counties require a licensed septic contractor for all installation and major repair work. Use this directory to find BBB-rated, licensed, and insured providers serving your area.
