Patent for sewer design, 1888. Patented by W. A. Pitt on May 1, 1888. U.S. Patent No. 382,188. 1 sheet. See full text description. (Use back button to return to graphics section.)

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.
