Resolution setting a Public Hearing for April 20, 2020 at 7:00 p.m. for the East Manawa Sewer Rehab, Phase IX.  Project # PW21-09

The area of East Manawa is very flat with open ditches.  There are no storm sewers in this area and the streets are thin asphalt or seal-coated rock roads.  During rainfall events, considerable surface ponding occurs due to the poor drainage.

Due to the narrow right-of-way (30 ft.) and the high water table in the area, conventional storm sewer construction is not practical.  The use of porous pavement in conjunction with a drainable granular base and shallow subdrain/conveyance system was determined to be the most cost effective means available to improve the area drainage.

The rehab program also includes installation of new sanitary sewers utilizing a vacuum system.

Phase I and II of the program included Huron Circle from Navajo to north of Osage Street.  Phase III of the program was construction of the sanitary sewer vacuum pump station. Phase IV was the first phase of vacuum sewer installation with the porous pavement and subdrain system on Huron Circle from Navajo to just west of Blackhawk Street.  Phase V continued the rehab along Huron Circle from just west of Blackhawk Street to 585 feet east and Osage Street from Huron Circle to Victor Street. Phases VI and VII are now complete and included Blackhawk Street, Victor Street from Osage to Blackhawk Street, and Aztec Street from Huron Circle to Victor. Phase VIII is currently under construction and includes Victor Street and Aztec Street from Victor to the south. Aztec Street is complete and Victor Street is scheduled to be complete in April.

Phase IX includes extending the vacuum sewer along the west side of Navajo Street from just south of Huron Circle to south of Victor Street and reconstruction of East Navajo Street from Victor to Huron Circle.

This project is planned for the FY21 CIP and includes a budget of $1,000,000 in Sales Tax Funds.
