MSD to Carry Out $4.7bn Sewer System Improvements

The Metropolitan St Louis Sewer District (MSD) will spend $4.7bn on improving its sewer systems and treatment plants in Missouri, US, over the next 23 years.

The move is part of a settlement made with the US Government, the Missouri Coalition for the Environment Foundation and MSD.

MSD’s improvements will eliminate illegal overflows of untreated raw sewage, including basement back-ups, and reduce pollution levels in urban rivers and streams.

The utility will also develop and implement a comprehensive plan to eliminate more than 200 illegal discharge points within its sanitary sewer system.

It will also carry out comprehensive and proactive cleaning, maintenance and emergency response programmes to improve sewer system performance.
