Okoboji Harbor

Okoboji Harbor Sewer Rehabilitation Page

The Okoboji Harbor sewer system was installed with the construction of the canals in the early 1960’s. The sewer system was maintained at the time by the developer of the Okoboji Harbor. In 1978, the sewer system and easements were transferred over to the Iowa Great Lakes Sanitary District and made public. At the time of installation of the private sewer and the transfer to the Sanitary District, the District has no established standard material requirements. Today, the Sanitary District would not allow such a transfer unless the system was brought up to the District’s standards.
In 2012 the Sanitary District purchased our easement machine that allows us to clean the sewer in tight locations around the lakes. The Okoboji Harbor area was cleaned and then inspected with a camera. The issues found were several including; sunken pipe sections, deformed pipes, missing manhole bases, and much more (Harbor Pipe Issue Photos Found Below). After investigation, the issues were brought to the Trustees of the Sanitary District to review for possible action. It was decided in 2013 that this would need attention as soon as possible.
In the fall of 2013 the Sanitary District hired HR Green, Inc. to study the sanitary sewer facilities in the area of the Harbor and provide solutions and cost estimates for rehabilitation of the system. HR Green completed this work and presented three options. The first option was to move the sewer to the off- lake side of the homes. The second option was to bore pipes adjacent to the existing sewer pipe. The third option was to rehabilitate the existing pipe using a combination of pipe- bursting, pipe lining and open cut replacement in the current location. The first option was not possible as the relocated pipe elevations do not allow the sewer to gravity flow. The second option is possible but more expensive and more has more disruption to property. The third option would still have some disruption but it would be very limited to specific areas. The Trustees agreed to proceed with the third option.
The third option will involve three different types of rehabilitation: pipe bursting, pipe lining and open trenching. The goal is to use as much pipe lining rehabilitation as possible; then rehabilitate with pipe bursting in areas that cannot be lined; and finally open cut replace the remaining areas that cannot be rehabilitated by lining or pipe bursting.  You can learn about pipe bursting by clicking on the line below for Section A, pipe lining is explained until the Section B link below and the manhole rehabilitation is listed under the Section C line below.

Okoboji Harbor – Section A

Section A work is the most intrusive part of the sewer rehabilitation project.  The Iowa Great Lakes Sanitary District is trying to minimize the impact to property owners as much as possible.  The main trenchless technology being used is pipe bursting.  Pipe bursting is a trenchless pipe replacement construction method. It is little more disruptive than pipe lining, but less disruptive than open cut replacement.  For pipe bursting all sewer service connections along the sewer main are dug up and disconnected.  Then a cable or rod is extended through the entire sewer main pipe section to be busted.  On one end of the cable a “spade head” is added that is larger than the existing pipe.  Connected to the back head is the new sewer pipe.  The head is pulled through using a winch machine breaking up the old sewer main pipe along the way.  The new sewer main pipe is pulled into the existing sewer main pipe cavity from behind and replaces the old pipe.  Once the new sewer main pipe section is installed the private sewer service lines are reconnected to the new sewer main pipe.  The final step is to connect the new sewer main pipe to the existing manholes and the replacement of the sewer main is completed.

Along with the Section A work, 14 manholes will be partially or completely replaced.  These manholes are in poor condition and will need to be replace in the next 5 to 10 years.  Instead of coming back to replace these manholes in 5 to 10 years, the Iowa Great Lakes Sanitary District is going to do all the work necessary with this project.  There is one location where a manhole will relocated.  There is another location where the distance between manholes exceeds the minimum requirements established by the Iowa DNR and a manhole will be installed to split this pipe distances.

Another part of the Section A work is to repair the sewer lift station found on Breakwater Drive.  This work will shut down at least one lane of traffic on Breakwater Drive.  The plan is to remove the top section of the lift station and rebuilt it in place.  This will help reduce the amount of water that is entering into the lift station through cracks and joints.  Other steps that are planned to take place in the area of the lift station is the installation of tile lines and storm sewer intake.  This will help reduce the puddling of the water in this area and keep the water out of the lift station.

Okoboji Harbor – Section B


Section B of the rehabilitation project is scheduled for August of 2015.  This part of the project is to install a structural liner in the existing pipe where the was not deformed or had minor issues.  Pipe lining will be done in some of the areas were open trench repairs were made to ensure the entire pipe is one solid piece.  The structural liner is like installing a new pipe inside the old pipe.  The new pipe will have the strength to meet the requirements of the Iowa Great Lakes Sanitary District.

Municipal Pipe and Tool Company from Hudson, Iowa was the low bidder on this project.  Will plan to start the second week of January 2016 and believe it will take about two weeks for the main line work.  Then they will have a sub-contractor finish up the service connection lining.  The service connection line is adding a liner into the private sewer services in the pipe lining area.  This liner will extend five feet into the private services and ensures a good bond and transition from the private sewer to the public sewer service.  The private sewer service work will be done from the second week on January until about the second week of February.

The contractor during will be contacting property owners five days and 24 hours prior to them doing any work.  Some sewer services will be down for a few hours but the time should be minimal.


Pipe lining is basically placing a pipe within a pipe, without digging up the entire pipe to be fixed.  This is a very cost effective way of repairing older pipes that need to be sealed or strengthened that do not have deformations present.  The process is started by cleaning the sewer line.  Then a felt-type liner with a resin material (glue) is placed into the pipe and is cured in place.  The completed product is a new pipe as strong as new PVC pipe, inside of the old pipe.  The private service connections to the newly lined sewer main are then cut out by a remote-controlled machine from the inside of the sewer main pipe.  A piece of the pipe liner material is added into the private service pipe to secure the private sewer service pipe to the new liner in the sewer main.  See the video below for more details.

Okoboji Harbor – Section C

Manhole Lid to the Public Sewer.

Section C work for the Okoboji Harbor Sewer Rehabilitation project is working with the manholes in the sub-division.  This will be working internal grout of the public sewer manhole and then using a spray liner inside of the manholes.  These products are used to limit ground water from getting into the sewer system.  The grout and liner will also extend the lift of the manholes.  This will be the last section of the project.  It will be done in the spring of 2016 when the ground temperature has reached the proper temperature for the grout and liner to be installed.
