Beck Engineering, Inc. was retained to design the rehabilitation of the sanitary sewer system in the north portion of Lake Park, Iowa. The project includes designing a Cured-in-Place Pipe (CIPP) Liner to be installed inside the sanitary sewer main, testing and chemical grouting of the sanitary sewer service connections, and installing a centrifugally cast cementitious liner in the manholes. All of this work was completed through the manholes without having to dig up the streets/lawns which provided a significant cost savings and significantly less disruption. The project was funded by a $500,000 Community Development Block Grant (CDBG) and an $836,000 State Revolving Fund (SRF) loan obtained from the Iowa Finance Authority. Construction on the project began in the fall of 2010 with construction of new manholes on existing dead-end lines and sanitary sewer main spot repairs. Installation of the Cured-in-Place Pipe Liner began in March 2011. The project was completed in May 2011.
