"Lateral" is defined as a pipe used to convey wastewater from a property or facility to a wastewater main owned by Westtown Township. This definition also applies to privately owned mains which collect wastewater from one or more properties or facilities and connect to wastewater mains owned by Westtown Township.

The permittee must submit the results of the low-pressure air test to the Township, or its designee, prior to commencing construction.
