Water Supply & Assessment

RAIN is a voluntary, collaborative, proactive effort amongst public water supply systems in western Pennsylvania and northern West Virginia to protect public health by ensuring a safe and reliable source of drinking water.

RAIN administers an early warning/spill detection network that include numerous public benefits:

  • Automated alerts and alarms in response to rapid changes in water quality
  • A Source Water Environmental Education Team (SWEET) that conducts outreach and public education/awareness efforts, and through collaborative efforts with its partners (such as Penn’s Corner Resource, Conservation and Development Council)
  • Assists in identifying and prioritizing water quality concerns in the river basins in an effort to remediate such concerns and protect the overall health of our shared watershed resources.

The 51 RAIN member systems share a common trait; they use regional rivers—the Ohio, Allegheny, Monongahela, West Fork, Tygart Valley, Buckhannon, Cheat, Youghiogheny, Beaver and Shenango—as their source of drinking water. The Monongahela River, alone, is the water source for 14 Rain member systems. Any contamination issue in the Mon has the potential to impact 1.5 million residents who rely on those systems for their drinking water.
