NAC445A.9678. Alternative absorption system.

     1. If an on-site sewage disposal system cannot use absorption trenches pursuant to NAC 445A.9676 because of limiting conditions, including, without limitation, high groundwater, highly permeable stratum, sloping terrain or shallow bedrock, the Division or other administrative authority may approve the use of an alternative absorption system.

     2. Any plumbing fixture served by an alternative absorption system must be a low-flow fixture designed for an on-site sewage disposal system that is used where the percolation rates are slower than 60 minutes per inch. Each such fixture must be specifically identified by the design engineer on the design specifications for the alternative absorption system.

     3. A design engineer who is designing an alternative absorption system must consult the Design Manual: On-site Wastewater Treatment and Disposal Systems and the On-site Wastewater Treatment Systems Manual, both of which are adopted by reference pursuant to NAC 445A.9592.

     4. In addition to the provisions of subsection 3, a design engineer who is designing an alternative absorption system must contact and consult with the Division or other administrative authority concerning design parameters before submitting design specifications pursuant to NAC 445A.9614.
