Notes of Decisions Treatment Tank
A county zoning boards description of a package treatment plant designed for twenty mobile home units, piping effluent 800 feet to the nearest perennial running creek, appears to fit the definition of aerobic sewage treatment tank in 25 Pa. Code § 73.1 (relating to definitions). Voortman v. Bucks County Zoning Hearing Board, 343 A.2d 393 (Pa. Cmwlth. 1975).
