Consent Decree Progress

MSD is working to complete Phase 1 (2009-2018) of our multi-phased program to reduce combined sewer overflows (CSOs) into local streams and rivers and eliminate sanitary sewer overflows (SSOs).

Accomplishments to date include:

• Reduced CSO overflow volume by 6 billion gallons a year during a typical year of rain (41 inches) - from 14.4 to 8.4 billion gallons - by removing stormwater from the combined sewer system, eliminating pump stations, installing new sanitary and storm sewers, improving existing treatment plants, installing new wet weather facilities to store and treat CSOs, and implementing Smart Sewers.


• Completed 84% of the projects to date required under Phase 1, or 112 of 133 total projects. Note: MSD is now counting all the Lower Mill Creek Partial Remedy (LMCPR) projects individually.


• Eliminated or significantly reduced 51 Combined Sewer Overflows (CSOs). A total of about 146 CSOs have been controlled over the years, with 201 remaining.


• Eliminated 44 Sanitary Sewer Overflows (SSOs), including the 17 most highly active. A total of about 154 SSOs have been eliminated over the years, with 51 remaining.


• Eliminated or upgraded 24 pump stations to prevent Pump Station Overflows (PSOs). A total of about 67 PSOs have been eliminated over the years, with 22 remaining.


• Reduced overflow activations at SSO 700 (MSD's largest SSO) from 47 a year to about 8 during a typical year of rain.


• Improved water quality in local streams, with significant progress in the Mill Creek.


• Kept Phase 1 under budget. Phase 1 costs are currently trending at about $1.011 billion (in 2006 dollars) as compared to the original estimate of $1.14 billion. The Lick Run Project alone saved MSD customers more than $150 million as compared to the original underground tunnel solution.

Quarterly Project Reports

NOTE: From June 2017 on, there are only four reports, as all the District-Wide projects have met substantial completion.

This quarterly report covers the status of key projects currently in construction, including budget, schedule and potential project risks. The report covers Phase 1 Consent Decree (wet weather projects) as well as selected Asset Management projects. The projects are reported in a watershed-specific report or in a district-wide report. Please note: This report was published monthly through December 2016.
