Main Line Overflow Rate

General information

Measures sewer overflows originating within SASD’s system per 100 miles of sewer main lines in any calendar month, regardless of the volume or whether the sewage enters a waterway. It takes into consideration the fact that a larger system, similarly managed, will experience more overflows than a smaller one.

Target: 0.45

A set value of 0.45 sewer overflows per 100 miles of sewer main lines. This target reduces each year.
