| | | | | | | | Background/Discussion
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. Phases V through IX continued the rehab and completed Huron Circle, Blackhawk Street, Osage Street, Victor Street, Aztec Street, East Navajo Street and extended the vacuum sewer along Navajo Street. Phase X included Pickard Lane from Hall Walk (Alley) south to Navajo Street. Phase XI includes Pickard Lane from Hall Walk (Alley) north to Navajo Street. Phase XI is scheduled to be complete in July 2023.
Phase XII includes extending the vacuum sewer along the east side of Navajo Street from the pump station at the intersection of Mohawk and Navajo Street to Comanche Street and along the south side Comanche Street from Navajo Street to Apache Street.
This project is included in the FY24 CIP and includes a budget of $700,000 in Local Option Sales Tax funds and $300,000 in Sewer funds.
