About

The Metropolitan St. Louis Sewer District was created on February 9, 1954 when voters approved a plan to combine 79 regional sewer districts into one city-wide system for the collection, treatment, and disposal of wastewater.

The Metropolitan St. Louis Sewer District is responsible for the interception, collection, and treatment of wastewater for approximately 1.3 million residents of St. Louis City and County. We also provide stormwater management to this vibrant and diverse customer base.

MSD is currently completing the second phase of a multi-billion dollar, multi-decade program to modernize our region’s aging wastewater infrastructure. These investments are funded primarily through a combination of customer rates and bond sales.

MSD benefits from:

- an experienced management team with proven planning capabilities

- effective debt policies

- solid operating performance

- the cash and reserves needed to meet debt obligations

- strong legal provisions to protect bondholders
