DES issues permits to septic system designers and installers to ensure that effluent disposal systems are properly designed and installed. DES will issue a permit to any person who demonstrates a sound working knowledge of the procedures and practices required in site evaluation and the ability to read approved waste disposal plans.
DES administers examinations two times per year, with the major testing taking place in the spring and fall. Reexaminations are given throughout the year by appointment only. An installer or designer permit is issued upon successful completion of the appropriate examination. The designer’s exam consists of three written portions and a field test for soil interpretation. Installers must pass a two-part written examination only. The examinations are intended to ensure that designers and installers can design and install appropriate systems for a variety of site and use conditions. See Permitting of Installers and Designers of Subsurface Sewage Disposal Systems (Fact Sheet WD-SSB-4).
For both designers and installers, the fee is $80 per exam; $80 per biennial renewal.
The estimated processing time for a licensing decision after an exam is passed is five days.
Effective January 1, 2009, permits for both designers and installers are valid for 2 years beginning on January 1 and expiring on December 31 of the following year.
Pursuant to RSA 485-A:35 & 36, permitted designers and installers are required to complete six hours of DES approved continuing education within a renewal period. This requirement must be met to be eligible for each biennial permit renewal. Please note; individuals jointly permitted as both a designer and installer are only required to obtain six credit hours per renewal period. For more information, please see the Continuing Education section.
Any person aggrieved by a final decision of the Subsurface Systems Bureau can submit a request for reconsideration in accordance with RSA 485-A:40.
