NAC445A.54034. Design of facility to be based upon pilot plant study; approval of treatment technology without pilot study.

     1. Except as otherwise provided in subsection 2, the design of a groundwater treatment facility must be based upon a pilot plant study. The pilot plant study must identify:

     (a) Hydraulic characteristics such as the optimum process loading rate or the proper blending rates; and

     (b) The unit process performance such as the optimum chemical feed and the most effective chemicals to use for adequate removal.

     2. If the treatment technology recommended in the preliminary engineering report required pursuant to NAC 445A.54024 or 445A.54026 has been tested on water with similar characteristics, the treatment technology may be approved without a pilot study. Documentation must be provided to verify that the treatment technology has been proven to treat the drinking water to the minimum requirements set forth in NAC 445A.453.
