Time and cost savings through PreFab at the Leimen wastewater treatment plant

Through precisely fitting, pre-fabricated solutions, construction costs at the Leimen wastewater treatment plant could be significantly reduced. The pipeline contractor Tecoba mastered the challenges at the Leimen wastewater treatment plant, limiting assembly to the connection of the specially pre-fabricated modules from egeplast – thus realizing time and cost advantages.

The pipeline contractor Tecoba faced major challenges in the implementation planning for the wastewater treatment plant in Leimen. Due to the size of the construction site with many trades and large pipe dimensions, many complex installation situations typically arise, such as the integration of concrete structures, coverings, dimension changes, as well as confined spaces and branching. Creating the entire pipeline from commercially available individual parts on site would have involved a very high expenditure of time, material, and personnel, and the skilled personnel would have been tied up on site for a long time.

Pre-fabrication of modules by egeplast

The solution was to divide the required pipelines into sensible modules and limit the assembly effort to connecting these modules. In close cooperation between Tecoba and egeplast technicians, a total of eight modules were planned and manufactured, which were divided into transportable and manageable components.

Using the available construction plans, the eight modules were precisely designed with all necessary components and, after approval by Tecoba, manufactured, labeled, and securely packaged for transport in egeplast’s system technology department. This allowed for direct and easy assignment of components to their respective installation locations on site. Assembly could begin immediately after delivery and was partially completed on the same day.

“Flawless on-site production from individual components would have been almost impossible in this quality due to the prevailing conditions (weather, dirt, cold, water, lack of special tools, etc.),” said Ralf Kaufmann, Managing Partner of Tecoba.
