Septic Plans

Your septic system plans may be available on microfiche or from NH DES (if it is a newer septic system).  If your septic system is older than 1967, we may not have a copy on file.  If we have a copy of your septic design on file, we can email it to you upon request.  Please email ginnyrioux@derrynh.org and enter septic request in the subject line, please include the property address.  Please allow 3 business days for all emailed requests.    

Minimum design standards for septic systems were established for New Hampshire in 1967 for systems located within 1000 feet of surface waters. In 1971, all systems were included in the law.  Please visit https://www.des.nh.gov/land/septic-systems for more information regarding septic systems.
