System Data
Flow Information
Tracking wastewater flow from each municipal member and maintaining data quality through our Flow Meter Quality Control Program.
Flow Contribution by Municipality
See below contribution from each municipal member. These meters measure at least 75% of the flow from each of our member municipalities.
The Authority has initiated a Flow Meter Quality Control Program to ensure that the data we receive from each meter is accurate. Our Maintenance Committee reviews the flow data annually to ensure its accuracy.
The Authority has gathered a significant amount of information concerning our flows. Here are links to some of that information.
Private Property Infiltration & Inflow
What are we talking about?
Over 85% of the Authority's budget is for the treatment of our municipal members' flows. Unfortunately, our flows are significantly impacted by rainfall. Rain water soaks through the ground and into the sewers through cracks or bad connections. Each municipal member and the Authority are constantly working to find and repair these leaks into the sewer system.
House Laterals
A significant amount of extraneous flow enters the sewer system through the pipe that connects each home to the sewer in the street. This is called a house lateral and is the property of the home owner. These pipes are rarely inspected or repaired. Consequently a significant number of them are in disrepair. Rainwater and groundwater that should soak into the ground are allowed to enter the sewer system. Once in the public sewer system, the rainwater and groundwater undergoes unneeded treatment which everyone pays for in their sewer bill.
DELCORA Report & Video
In June of 2010, a report on private property infiltration & inflow was issued by DELCORA. In addition, a companion video was also produced.

WEF Private Property Virtual Library
The Water Environment Federation (WEF) maintains a "Private Property Virtual Library" on its website. This is a growing library of case studies from private property-related programs at wastewater utilities. It is intended to be a resource for other utilities seeking information or advice about private property programs.
