Service Levels

Backups Into Structures Rate

Measures the number of times, per 10,000 connections, that a stoppage in the District's sewer system causes sewage to backup into a structure within any calendar month. (Plugged fixtures or stoppages within building plumbing are not considered a backup into structure.)

Target: 0.71

A set value of 0.71 events per 10,000 connections to our system. 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.
