The Iowa Great Lakes Sanitary District has started a project to create more capacity for the center core system of the Sanitary District’s collection system. This project includes a new lift station that will be located north of the intersection of Lakeshore Drive and 220th Avenue (west of Center Lake). This lift station will replace the 1930’s era lift station that is within 120 feet of West Okoboji Lake on Alexander Street, in the City of Okoboji. The new lift station will pump water south down Lakeshore Drive, then east on Nature Center Road (formerly County Home Road) to the Nature Center where the line will then turn south to the Brooks Golf Course. At Brooks Golf Course the new sewer force main will go under the golf course towards an area behind Liberty National Bank. The line will then go south to Brooks Park Drive to the Highway 71 Right-of-Way then go south in front of Amercinn and Arrowood Resort where it will connect with the existing public sewer system.
The lift station project has started and is contracted to be substantially completed by September 25, 2020.
The pipe line is broken up into four bid packages.
Bid Package #1 is the open trench installation of sewer from south parking lot of Arrowwood Resort north to AmericInn, then west approximately 550 feet, then the line will go north about another 900 ft and stop. This will be all gravity sewer that will be installed. Bid Package #1 is to be substantially completed by May 1, 2020.
Bid Package #2 is the directional boring installation of force main sewer in two areas. The first directional boring will start in an area behind Liberty National Bank and will go under Brooks Golf Course to the north west into an area south of the Nature Center. The pipe will then go on the west side of the current Nature Center Driveway up to Nature Center Road. The second directional boring area will be from the intersection of Nature Center Road and Lakeshore Drive going north to the new lift station site. The pipe will stay on the east side of Lakeshore Drive. Bid Package #2 is to be substantially completed by May 8, 2020.
Bid Package #3 is the open trench installation of force main sewer to connected the two direction drilling sites. Along with this a new gravity sewer line will be installed from Lakeshore Drive east to the Nature Center, on Nature Center Road. This project will be substantially completed by May 29, 2020.
Bid Package #4 is open trench installation of new gravity sewer from the old lift station on Alexander Street to the new lift station site. This work will start in the early fall of 2020.
