The Chiques Creek Watershed Alliance (CCWA) will host an informational presentation and discussion, "All About MS4," at the West Hempfield Township office, 3476 Marietta Ave., Lancaster, on Wednesday, Feb. 5, from 5 to 6 p.m. Dwayne Steager, director of land use for West Hempfield Township, will present and invite follow-up discussion. 

Municipal Separate Storm Sewer Systems (MS4) are distinguished from combined sewer systems in larger municipalities in that MS4 does not send stormwater to sanitary sewage treatment plants. This also reduces the chance of sanitary sewage overflow into creeks during heavy storm events.

But MS4 compliance requires implementing a variety of sometimes costly stormwater management systems. The presentation will offer a chance for the public to hear from a local expert on the subject and to understand the practices, the benefits and the future prospects for MS4 in the area. 

MS4 is helping to make communities more resilient to intense storms and flood events in the future.

This is one of several events during 2025 celebrating CCWA's 25th year.
