The Water Pollution Control Authority (WPCA) oversees the town's sanitary sewage collection system. Per state statute (chapter 103), the WPCA has the authority and the responsibility to plan, acquire, construct, equip, extend, enlarge, maintain, repair, reconstruct, operate, supervise and manage a municipal sewerage system. The WPCA also may have jurisdiction over community or private sewerage systems. The WPCA has the authority to levy assessments against properties which benefit from the sewerage system(s). The WPCA may establish fair and reasonable charges for connection with and for the use of a sewerage system. Billing in East Hampton is done through the tax office.
