== Treatment Facilities ==

Three major treatment facilities process water for the Philadelphia system:

'''Baxter Water Treatment Plant''' - The largest facility, treating Delaware River water for distribution throughout the eastern portions of the system.

'''Belmont Water Treatment Plant''' - Treating Schuylkill River water for the western distribution area.

'''Queen Lane Water Treatment Plant''' - Additional Schuylkill River capacity serving portions of the system.<ref name="pwd"/>

Treatment processes include coagulation and flocculation (causing particles to clump together), sedimentation (allowing particles to settle), filtration (removing remaining particles), and disinfection (killing microorganisms). Additional processes address specific contaminants depending on source water conditions. The treated water meets or exceeds Safe Drinking Water Act standards.<ref name="pwd"/>
