This project was a full street renewal of 1.1km of Dn375 sewer mainline and all associated wastewater laterals. We used the trenchless technology to install the laterals via hydro excavations and pipe bursting from private boundary to mainline. We had some positive challenges along the way, from building Large in-situ chambers around the wastewater network, to varying ground conditions and depths.
