"Pump chamber or pump basin" means a watertight container with a capacity of 50 gallons or less and which houses a float or liquid level activated pump and associated appurtenances used to convey sewage or effluent. The capacity of a pump chamber is measured at the normal high (pump start) operating level. The capacity of a chamber housing a pump or used as a pump basin is not considered part of the treatment volume required for a septic tank and is not subject to tank setbacks for the purposes of these regulations.
