Ground Sun was appointed to design, supply, and install AB Chance Helical Screw Pile foundations for a new Inlet Chamber at Borstal Reservoir, Rochester, Kent which is operated by Southern Water
The Inlet Chamber forms a vital part of the local water infrastructure network, safely directing treated drinking water into storage facilities before distribution to homes and businesses throughout the community.
The screw piles for water infrastructure project involved the installation of approximately 100 helical screw piles using a 5-tonne excavator equipped with a specialist 20,000Nm high-torque drive motor. To ensure optimum performance and accuracy in varying ground conditions, an AB Chance Bluetooth torque monitoring system was used throughout the installation process. This enabled real-time verification of pile capacities and precise termination depths across the site.
Given the sensitive nature of the water infrastructure, maintaining the highest standards of hygiene was essential. All Ground Sun operatives held EUSR National Water Hygiene accreditation, ensuring full compliance with industry requirements.
The installation for this screw piles for water infrastructure project was completed efficiently within approximately 10 days, providing a robust, reliable foundation solution while minimising disruption to the wider reservoir operations.
