Section 444.8374 - Alternative absorption system: General requirements1. If an individual sewage disposal system that uses absorption trenches pursuant to NAC 444.8352, 444.8354 and 444.8356 cannot be used because of limiting conditions, including, without limitation, the existence of high groundwater, a highly permeable stratum, sloping terrain, bedrock, or a layer of semi-impervious soil with a percolation rate that is slower than 60 minutes per inch, the health authority may approve the use of an alternative absorption system if the alternative absorption system is designed by an engineer.2. Except as otherwise required by design modifications approved by the health authority, an alternative absorption system must comply with the regulations which pertain to a standard disposal trench.3. A connecting fixture used in an alternative absorption system must be a low-flow fixture designed for an individual sewage disposal system that is used where the percolation rates are greater than 60 minutes per inch. Each such fixture must be specifically identified by the engineer on the design plans for the alternative absorption system.4. An engineer who is designing an alternative absorption system must consult the Design Manual for On-site Wastewater Treatment and Disposal Systems which is published by the Environmental Protection Agency (reference document number PB83-219907), and contact the health authority for design parameters for the alternative absorption system before the engineer submits the design plans to the health authority.Nev.
