Stormwater Management

Rain and snowmelt runoff serves an important purpose in helping to replenish the water supply and fill streams and lakes. However, when this stormwater runoff contains pollutants, the discharge into surface water bodies and the groundwater can have a detrimental effect.

Some common pollutants that runoff with water into storm drains include:

  • Grease
  • Oil
  • Pesticides/herbicides
  • Pet waste
  • Plastic
  • Construction debris

TEC can maintain the right systems that detain stormwater and help prevent pollutants from migrating off-site via strategies including gray infrastructure, storm sewers, piped drainage, culverts and more.
