Bigger than seven Mississippi River bridges, 11 Busch Stadiums or nine I-64 rebuilds, the MSD Project Clear initiative will be a generation in the making and will improve our community’s infrastructure for generations to come.

Begun in 2012, MSD Project Clear is a long-term effort by the Metropolitan St. Louis Sewer District (MSD) undertaken as part of an agreement with the U.S. Environmental Protection Agency and the Missouri Coalition for the Environment. Approximately 1.3 million people living over 520 square miles are served by MSD Project Clear. The goal for this $6 billion, 28-year initiative is ambitious but within reach:

  • Improve water quality and minimize wastewater and stormwater issues
  • Resolve community issues caused by the nature and design of St. Louis’ legacy wastewater system
  • Plan, design and build community rainscaping projects
  • Keep the public informed with clear and timely updates
