Clean Water Act

The Clean Water Act was passed in 1972 by the U.S. Congress to control pollutants that were being dumped into our nation’s waters. The Clean Water Act gave the Environmental Protection Agency the authority to set standards for industry pollution. The act also made it unlawful for any individual to pollute any waterway. The Clean Water Act’s main goal is to restore and maintain the chemical, physical and biological integrity of the nation’s waters so they can support fish, shellfish, wildlife and recreation. Be aware: Only rain in the drains help keep pollution out of storm drains. Storm drains and roadside ditches lead directly to lakes, rivers,creeks and streams. Oil, trash, leaves, debris or dirty water from cleaning cars flowing into a storm drain gets into our waterways. We all need to be aware of what goes into our storm drains; awareness is important. Many people believe storm drains are connected to sanitary sewer systems and that storm water is treated at sewage treatment plants. This is NOT TRUE. Storm water is not treated. People carelessly dump many pollutants like motor oil, pesticides and paint into storm drains. Nonpoint source pollution is ranked as one of the highest ecological risks because it poses a significant threat to the birds, fish and aquatic life that live in our waterways. Please help us keep storm drains clean, especially during wet weather events. Township Officials ask residents who see anyone dumping into curb drains or storm sewers to please notify the Public Works or Police Department as soon as possible. Residents who see a catch basin or a storm sewer covered with debris should remove the debris to allow the drains to accept water flow.

Letter from Leyden Township

Dear Township Resident,

The Internet has become a tool many communities use to educate the public on issues specific to their community. In addition to information that is currently posted, Leyden Township will now provide information on the internet regarding storm water issues and what the Township plans on doing to solve storm water problems. Any materials published will now be available on the Township website: Materials that focus on specific topics or target specific audiences, as well as a link to a regional water quality web-site IEPE, will also be included.

Flood Safety

The following common sense guidelines can help protect you from the dangers of flooding:

  • Do not drive through a flooded area. More people drown in cars than anywhere else. Do not drive around barriers.
  • Do not walk through flowing water. Currents can be deceptive. Six inches of water can knock you off your feet.
  • Stay away from power lines and electrical wires. If your house is about to be flooded, turn off the power at the service box. Electrical current can travel through water. Electrocution is the second leading cause of death during floods.
  • Be alert to gas leaks. Turn off the gas to your house before it floods. If you smell gas, report it to Nicor Gas at 1-888-642-6748. Do not use candles, lanterns or open flames if you smell gas or are unsure if your gas has been shut off.
  • Keep children away from the flood waters, ditches, culverts and storm drains. Flood waters can carry unimaginable items that have been dislodged. Culverts may suck smaller people into them rendering them helpless.
  • Look out for animals, especially snakes. Small animals that have been flooded out of their home may seek shelter in yours.
  • Do not use gas engines, such as generators, or charcoal fires indoors during power outages. Carbon monoxide exhaust can pose serious health hazards.
  • Clean everything that has been wet. Flood water will be contaminated with sewage and other chemicals which pose severe health threats.

Leyden Township Monthly Storm Water Topic


  • Use local alerts, radio stations, and other local information sources, such as American Red Cross apps, to get information and advice as soon as available.
  • Use text messaging or social media to communicate with family and friends. Telephones and cellular phone systems are often overwhelmed following a disaster, so use phones only for emergency calls.

Health and Sanitation

  • Listen for news reports to learn whether the community’s water supply is safe to drink.
  • Service damaged septic tanks and leaching systems as soon as possible. A damaged sewage system is a serious health hazard.
  • Have wells checked for contamination from bacteria and chemicals.
  • Clean and disinfect everything that got wet. Mud left from floodwater can contain sewage, bacteria, and chemicals. Take precautions and wear appropriate protective equipment such as gloves, safety glasses, and face masks. Follow five basic steps for post-flood building restoration, including (1) air out, (2) move out, (3) tear out, (4) clean out, and (5) dry out. Seek out professional services and/or guidance before attempting to repair flood-damaged property.
  • Throw out any food, including canned items, that was not maintained at a proper temperature or has been exposed to floodwaters. Do not eat food from a flooded garden. When in doubt, throw it out.
  • Remove and replace any drywall or other paneling that has been underwater. Use a moisture meter to make sure that wooden studs and framing are dry before replacing the drywall. Mold growth in hidden places is a significant health hazard.


  • Photograph damage to your property and contact your insurance agent. Do what you can to prevent further damage that insurance may not cover (e.g., putting a tarp on a damaged roof).
