Illicit Discharge Detection & Elimination
The City of Redmond Illicit Discharge Detection & Elimination (IDDE) Program is a key component of Redmond's National Pollutant Discharge Elimination System (NPDES
) Phase II Municipal Stormwater Permit
. This stormwater permit gives permission to discharge the rain that falls on the City into the 'Waters of the State'.
In other words, Redmond is required to follow rules set up by the State in order to dump rain water into streams, lakes, and other waterways. One of these rules, or permit conditions, is developing an IDDE program
. The goal of IDDE is to reduce the amount of pollution to streams, groundwater, Lake Sammamish, and the Sammamish River from stormwater drainage systems.
The program focuses on the elimination of improper connections to storm drainage systems, elimination of illegal dumping into storm sewers and minimizing the amount of seepage into the storm water system from the sanitary sewer system and septic systems.
We all know that what we flush down the toilet ends up at the wastewater treatment plant. What some people don't realize is that things that are dumped into stormwater catch basins and drains go directly to our lakes and rivers without treatment. These are the same lakes, creeks and rivers that we boat, fish and swim in.
The goal of the IDDE Program is to eliminate the discharges that are harmful to both people and the environment. If you would like to spread the message of protecting our waters by preventing illicit discharges, print and share the City's flyer Only Rain Down the Storm Drain

- The City will work with you to help you find the correct way to dispose of waste materials.
- Polluters are responsible for the cost of clean up after dumping or spilling pollutants into storm drains or waterways. This can be expensive.
- Offenders can be brought before the Hearing Examiner, fined and/or subject to other penalties.
To report a spill, or dumping issue, call the City of Redmond’s SPILL HOTLINE AT 425-556-2868! The spill hotline can provide resources and technical assistance in the event of an accidental spill as well. It is better to deal with a spill as soon as possible rather than allow it to expand and become a larger, more costly, environmentally harmful problem. We care about water quality, let us show you how much.
How You Can Help Keep Our City's Waters Clean
- Do not dump or allow pollutants to flow into a storm drain. This includes: oils, soda, warm water, carwash runoff, paint, window washing fluid…in short, ANYTHING! Remember, with very few exceptions, ONLY RAIN GOES DOWN THE STORM DRAIN.
- Do not allow wastewater from leaky dumpsters, or other containers, to drain into the storm drains.
- Storm drain systems are more than catch basin grates that collect water in parking lots. They also include grassy areas called swales, retention ponds, and other features. If you have a question about this, contact us at 425-556-2826.
- Dispose of Wastes and Other Materials Properly (DO'S).
- Painters: All brush cleaning should occur in a sink, not outside. All paints, thinners, and other chemicals should be disposed of properly. For information call 206-296-3976.
- Restaurants: Mop water and other wastewater should be dumped into a sink, not outside. Make sure that dumpsters do not leak fluid into storm drains. Dispose of fats, oils, and grease properly. For information call 425-556-2827.
- Auto Shops, Auto Supplies, and Auto Dealers: Recycle used motor oil, antifreeze, etc. For information call 206-296-3976. Use carwash containment kits to capture wastewater. For more information call 425-556-2822.
