The Pretreatment Information Exchange (PIX) was created by pretreatment personnel from the Allentown, Bethlehem, Catasauqua and Easton wastewater treatment plants.

Our objective is to bring municipalities, discharging businesses, regulators, environmentalists and concerned citizens together in a synergistic coordinated group to leverage limited resources through information sharing, networking, and mentoring; enabling businesses and municipalities that have successfully managed environmental issues to assist those with similar issues in a discrete and non-regulatory manner."
