Phase 4A of the West Hill Area Sanitary and Storm Sewer Separation project (WHSSSSP) is moving up 7th Street from Iowa Avenue and is nearing Locust Street. All of the storm and sanitary sewer work has been completed from Iowa to Spruce on West 7th Street. The Pine and Chestnut intersections will be closed to be prepared for paving. Linn and Spruce intersections are now open after having the new storm sewer inlets and piping installed. We anticipate that 7th from Iowa to Linn will be paved within the next week or 10 days. That section of West 7th is currently being prepared for paving.

Phase 4A of the West Hill Sewer Separation Project is tentatively scheduled to be completed by November 9. The original contract date was November 30.


The contract for Phase 4 of the West Hill Sewer Separation Project was awarded to KE Flatwork, Inc., Eldridge, Iowa, on April 5, 2018, in the amount of $6,109,522.45.

Background Information:

In 2004 Stanley Consultants Inc. signed a contract with the city to proceed with a study and projects for the West Hill area. On September 5, 2007, the city received a stamped Consent Order from the U.S. Environmental Protection Agency requiring that by December 31, 2010, the city would “submit to EPA and IDNR a report describing the projects needed to complete the separation of the remaining combined portions of the sewer system including the West Hill area”. The report “shall include a schedule and estimated cost for completing each project identified therein, and an update on the city’s plans for financing the projects”. Further, “By DECEMBER 31, 2024, completed all projects described . . . above”. Four projects have been identified, each estimated at $15 million to be implemented over the next 14 years to comply with the December 31, 2024 Consent Order date.
