Eco Lingo – “Rainwater Runoff”

30 April 2009 3 Comments

I just finished a big project this week in class. It involved redesigning a parking lot to reduce the amount of rainwater running off of it. Since I thought it was a fun and interesting project, I decided to share what I learned. This week’s Eco Lingo is “Rainwater Runoff

Rainwater runoff, also known as stormwater runoff, is the water that flows off an area due to a rain storm, melting snow, etc. Because objects such as roofs, sidewalks, and driveways are impervious (they don’t allow water to pass through them), the water can’t penetrate into the ground as it naturally would. The more impervious area you have, the more runoff you will get.

This is a problem because when the water flows over these areas it picks up pollutants such as oil from your car and carries it into our sewers and waterways. These are the same waterways that people swim and fish in. Higher amounts of runoff also means that there is more of a strain on the sewer system. The sewers will need to handle more water as more impervious areas are created.

    hey, so how did you reduce the water runoff in the project?

  • Chris said:

    We came up with a couple of ideas, the main one being to plant vegetation. We also came up with pervious pavement and filter strips. I am currently writing a new post that will describe these techniques along with a couple other ways to reduce runoff, so keep checking back!
