Service Levels

Lower Lateral Overflow Rate

Measures the number of sewer overflows originating within the District's system per 100 miles of sewer lower laterals 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: 8.4

A set value of 8.4 sewer overflows per 100 miles of sewer lower lateral lines. This target reduces each year.

In an effort to be more timely in our reporting, we have improved our service levels charts. We now include preliminary data for the most recent month which has not been through a final quality check. Once the preliminary data has been reviewed and double-checked, we update the chart. We hope you find our new way of reporting data more helpful. Click on the chart below to enlarge.
