Regional Offices
NH Map - NHDES Office Locations The main headquarters for the NH Department of Environmental Services (DES) is at 29 Hazen Drive in Concord, NH, 03301; (603) 271-3503. However, DES also maintains several regional offices to accommodate the public's need for various services, and it operates a regional wastewater treatment facility and training center based in Franklin.

DES maintains a regional office at Pease International Tradeport in Portsmouth that addresses the areas of septic systems, wetlands, coastal watershed management, waste management, and erosion control. DES also has small regional offices serving septic system needs, with one such office (in Grantham) that also serves regional waste management needs. The locations and contact persons for all of these regional offices are as follows:
