About Great Schools, Clean Streams

Great Schools, Clean Streams is New Castle County's annual environmental awareness campaign. Sponsored by the Department of Public Works, our goal is to help residents do their part to keep our waterways clean and safe, prevent plumbing problems at home, and support their local school system. 


Great Schools, Clean Streams is a pledge drive. No, we're not looking for donations! We partner with schools in the county to encourage residents to pledge to dispose of their used cooking fats, oils, and grease properly. Those who make this pledge can assign it to any public, charter, parochial or private school located in New Castle County, DE. The schools that collect the most pledges in their enrollment tier win cash prizes.

New Castle County is trying to stop untreated sewage from spilling from the sewer system into local streams and rivers. One cause of these spills is buildups of cooking fat, oils, and grease in sewer pipes -- known as FOG. When residents dump FOG down their kitchen sink, it builds up and eventually clogs.
