Water Supply and Quality

The Williamsport Municipal Water Authority (WMWA) furnishes water service to the Greater Williamsport Area's residents, businesses and institutions. The primary water supply is from a modern water filtration treatment plant which treats the water from the surface supply watersheds. Most of the watershed area is controlled by the WMWA. A wellfield supplements the surface supplies during dry years, normally for only two months every other year.

The surface supply treatment plant uses pretreatment, conventional filtration, and disinfection to produce high quality water. The pH and calcium carbonate saturation are adjusted to control corrosivity as part of the water treatment. The treated surface supply water has a relatively low hardness and the wellfield water has a moderate hardness; no softener is required for normal usage purposes. Both sources are fluoridated.
