The City of Redmond's Spill Response or Illicit Discharge Detection and Elimination (IDDE) Program is a key component of Redmond's National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Stormwater Permit.
The program focuses on investigation and response to activities or incidents that could result in the discharge of pollutants to storm drains and the environment, including elimination of improper drain line connections and contamination issues from sanitary sewer lines or private septic systems.
The goal of IDDE is to reduce the amount of stormwater pollution reaching streams, groundwater, Lake Sammamish, and any of Redmond's creeks from stormwater drainage systems.
Some Ways to Help Keep our City's Water Clean
Do not dump or allow any pollutants to flow into a storm drain. This includes: oils, soap, dirt, sand, heated water, vehicle fluids, paint, yard chemicals, etc.
Do not allow wastewater from leaky dumpsters, compactors or other containers, to drain into the storm drains.
Store liquid materials in leak-proof containers with tight fitting lids.
DO NOT dump cleaning solutions into a storm drain, onto concrete, or outside.
