Storm Water Sewer Pipes for Verona Installed in Mictrotunneling
The first part of the pipeline was laid in an open trench utilizing short 3 m pipes where the road was wide enough for this installation method. The second part of the pipeline was microtunnelled due to an installation in 4 m depth, a high groundwater level and the presence of old buildings along the pipeline route. Open trench was not an option in this case for the longer construction time would have meant more disruption for inhabitants, tourists and traffic. Design Engineer Luca Comitti at Acque Veronesi suggested microtunnelling, an installation method the water management department chose for the first time. This premier, Verona’s delicate buildings and monuments, and sceptic public authorities made a successful implementation imperative. Fortunately, the installation was awarded to Impresa Serpelloni a reputable contractor of the area specialized in no-dig techniques. Serpelloni and Acque Veronesi did not take any risks and decided to change the pipe material originally planned for the project. They switched to a reliable material that requires the least amount of equipment on site coupled with shortest installation times: HOBAS CC-GRP Pipe Systems.
