Metropolitan St. Louis Sewer District

Sustainable Practices

MSD alone cannot keep the region's waterways clean. We need the support, resources and actions of concerned citizens, businesses and municipalities to improve local water quality. Since our waterways and sewers are shared public resources, there are many steps that you can take to help maintain both.

Going Green

Prior to urban development, rain provided nourishment to a natural landscape of forests and wetlands. With development, we replaced these forests and wetlands with buildings and pavement, sending stormwater into sewer pipes, ditches, culverts and outfalls. This stormwater runoff carries pollutants into our local streams and rivers, damaging local ecosystems and watershed health and threatening our public health and quality of life.

This is where "going green" can help. Green infrastructure is cost-effective, sustainable and environmentally friendly because it captures and reuses stormwater to maintain or restore natural hydrologies.

Examples of green infrastructure include:

  • Rain gardens
  • Porous pavements
  • Green roofs
  • Infiltration planters
  • Trees and tree boxes
  • Rainwater harvesting (rain barrels)
