The intent of W. A. Pitt's patent was to provide one alternative way to better serve sewer customers in low, flatter areas; and in doing so, save some of the limited vertical fall available (for a gravity system) and reduce potential odors (via the use of compressed air and solids separation). Ultimately, the sewage is delivered to an area gravity collector sewer.
