This project involved the installation and upgrade of critical sewer infrastructure across a busy operational area. Works included 80 m of 75 mm UPVC SN16 sewer mains installed to depths of up to 3 m, and 230 m of 300 mm UPVC SN16 sewer mains to depths of up to 2.5 m. Four 1050 diameter concrete manholes were constructed with full benching to ensure long-term performance.

Additional works comprised 158 m of 100 mm sewer laterals and connections, using a combination of open trenching and pipe bursting methods to connect to live sewer infrastructure while maintaining service continuity. All works were completed under a high level of traffic management to ensure site and public safety.

Final stages included reinstatement of roads, footpaths, and park assets, delivering a fully functional, compliant, and durable sewer network with minimal disruption to the surrounding community.
