This project is for the installation of gravity sewer on the south end of Center Lake in Dickinson County, Iowa. The project will contain both guided directional boring methods and open trench installation of C900 pipe. This project is to allow for several properties in this area to be able to connect to the public sewer system and remove septic systems that are creating water quality issues in Center Lake and secondary issues for West Okoboji Lake. The notice to bidders can be found at the link below.
The Iowa Great Lakes Sanitary District has completed two major projects in the lakes area. Phase 1 of the Center Lake Project included installing over 17,000 feet of sewer pipe and the relocation of the Hayward Bay Lift Station. This work has closed some roads and limited access on others in Okoboji (Lakeshore Drive, Center Lake Road, Alexander Street and Nature Center Road) and on County Roads (Nature Center Road, 220th Avenue and 165th Street) for the last year. The road surfaces are all installed and open for through traffic again.
The Phase 1 of the Center Lake Project has relocated the Haywards Bay Lift Station out of the floodplain of West Okoboji, created capacity within the Sanitary District system from the City of Okoboji North and will allow for the public sewer to be expanded to the properties on the south side of Center Lake. The extension of the public sewer to the properties of Center Lake is to protect the water quality of Center Lake, by providing public sewer to allow for the removal of septic systems along 165th Street, 231st Avenue and 225th Place. The Sanitary District worked in cooperation with the City of Okoboji. Dickinson County Engineers Office, the Dickinson County Board of Supervisors and Dickinson County Conservation Board. The Sanitary District appreciates the public’s patience during this project.
The other project that has been completed was in the City of Arnolds Park in two areas. The first on Rohr Street in the area of Oar’s Campground and the second on Linden Drive in the area of Bridges Bay Resort. This project changed the public sewer pipes in this area to create more capacity for future growth along the east side of East Okoboji and Big Spirit Lake. Both Rohr Street and Liden Drive were closed for a few weeks during construction and to allow the concrete to cure. Both Rohr Street and Linden Drive have been reopened for through traffic. The Sanitary District worked in cooperation with the City of Arnolds Park on this project. The Sanitary District again appreciates the public’s patience during this project.
The Sanitary District is continuing to make improvement to the public sewer system around the Iowa Great Lakes. There are going to be some up coming road closure that will take place over the next couple of months that the District wants to make people aware of before the roads are shut down.
The first one is the final step of the new Haywards Bay lift station project. This project will be closing down all of Alexander Street, a portion of Lakeshore Drive and a portion of Center Lake Road. The map below shows the closure area.
The next area is on Linden Drive east of the City of Arnolds Park going towards Bridges Bay. The detour for this road will direct traffic to the stop light on Broadway Street and then to Rohr Street and around back to Linden. This will be a full road closure from Triggs Resort to past Bridges Bay Resort. The map below details the road closure area.
The last road closure will be after Linden Drive is fully restored and will be on Rohr Street. This full road closure that will start near Fehrway Drive and to Sandy Lane. The map below details the area of the road closure.
The first solar panels are going on to the racking as of 9/16/2020. This is the first of eight rows that will be going up.
The Solar Project at the Iowa Great Lakes Sanitary District Waste Water Treatment Plant started Construction on Tuesday September 8, 2020. The project will continue over the next several weeks. The Solar Project will provide up to 0.5 megawatt of power to off set cost power cost for the Wastewater Treatment Plant. The pay back is estimated to be about 7 years.
The wastewater Treatment Plant is located near the outlet of Lower Gar on 28th Street in Milford. The wastewater treatment plant takes wastewater from Orleans, Spirit Lake, Okoboji, Arnolds Park, West Okoboji Wahpeton, Milford and unicorporated areas around the Iowa Great Lakes. The plant treats about 2.5 million gallons of wastewater a day the discharges the treated water to Milford Creek.

The Iowa Great Lakes Sanitary District is starting the design phase of the South Center Lake Project. This project will be extending the public sewer to help improve water quality on Center Lake. The project will consist of installing a gravity sewer, a new lift station and a sewer force main. The project is projected to start in the fall of 2020 with the lift station.

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. 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 and go to 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 Arrowwood 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 sewer pipe installation 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.
