Haram Utility Service Project
The Haram Utility Services Project (HUSP) is a part of a comprehensive project of developing new sewer system tunnels in Makah. It consists of different parts including the TBM launching shafts, the tunnels, intermediate manholes and the receiving shafts. It is a very challenging project in a dense urban area.
The tunnels are excavated using two EPB TBM's. Due to the site condition and project requirements, a concrete segmental lining with HDPE inlining has been selected. The project involves several challenges and technical issues including mixed geological conditions, small radius curves and very strict water tightness requirements.
Stunex has been involved in different phases of the project from selection and procurement of the TBM's to design and site supervision.
