Summary:

The purpose of the Durkees Run Interceptor & Earl Ave. Reconstruction project was to divert stormwater from being directed to the Waste Water Treatment Plant, improve area wide drainage conditions to reduce street flooding in the Earl Avenue area and east of 18th Street near Lafayette Jefferson High School, and to improve roadway corridors in the area. These project objectives were met by separating existing combined stormwater and sanitary sewer lines that alleviates capacity problems in existing sanitary sewer further downstream and reduces raw sewage overflows into Durkees Run. After completion, over 100 million gallons of stormwater annually are diverted from the Lafayette wastewater treatment plant while preventing untreated sewage from flowing into the Wabash River.

The project was completed under the Indiana Guaranteed Savings Contract statute, which allowed for it to be split into multiple phases. Phase 1 of the project had to be completed quickly due to failure of an existing sewer along South Street in the summer while traffic associated with the Purdue populations was reduced. During Phase 2A a Stormwater Park, which includes multi-functional stormwater treatment elements that benefit stormwater management, education and passive recreation, was constructed north of Jefferson High School and ponds were installed west of 18th Street. Phases 2B and 2C of the project included storm sewer installation as large as 9 feet in diameter, road reconstruction, and trail construction along Earl Avenue to tie the improvements made in Phase 1 to the improvements made in Phase 2A.
