74:53:01:33. Absorption or alternative water-carriage system permitted under certain circumstances. An absorption system or alternative water-carriage system may be used when the percolation rate as determined by § 74:53:01:31 or 74:53:01:32 is between 5 and 60 minutes per inch if all other requirements for the absorption system or alternative water-carriage system are met. An alternative water-carriage system must be used when the percolation rate of the soil is slower than 60 minutes per inch or faster than 5 minutes per inch. An absorption system may be used where fill material is used to decrease the percolation rate from more than one but less than 5 minutes per inch to more than 5 but less than 60 minutes per inch.
