Peterborough Sewerage Scheme

Designed to enhance wastewater management in the Peterborough region through the development of a comprehensive sewerage system, the project began with the design and implementation of the town sewer reticulation network. This included installing pump stations and discharge rising mains, requiring detailed onsite scoping and design confirmation. Next was the development of an earthen lagoon-based wastewater treatment plant, designed to process and manage wastewater efficiently while addressing geotechnical challenges such as construction in a potential acid sulphate soil environment. The final stage was the creation of a pivot irrigation system for treated water reuse, promoting sustainable water management practices.

The project's challenges included managing environmental risks in low-lying coastal and estuarine areas prone to flood inundation, and protecting local flora and fauna, such as native orchids and the near-threatened Rufous Bristlebird. The Touch Projects team conducted thorough geotechnical investigations and integrated our findings into the project's design to ensure stability and safety. 

We adopted a meticulous and proactive management strategy to ensure project milestones were met on time and within budget. This included detailed onsite investigations, coordination with environmental specialists, and continuous stakeholder engagement.

A notable innovation for this project was the pivot irrigation system developed for the reuse of treated wastewater, facilitating sustainable water management through the repurposing of treated water for agricultural irrigation. The earthen lagoon-based wastewater treatment plant leveraged natural processes to treat the wastewater, providing a cost-effective and environmentally sustainable solution. Geotechnical challenges required innovative engineering solutions, including special considerations for soil treatment and construction techniques in order to mitigate risks associated with acid sulphate soils and potential flood inundation. Comprehensive environmental protection measures were implemented to safeguard the local flora and fauna, including habitat protection, scheduling construction activities to avoid critical periods for wildlife, and vegetation management strategies.

This project was a critical and successful development for the Peterborough region's wastewater management, highlighting the importance of meticulous project planning and management.
