We are delighted to announce that Dr Neil Sewell, Director of New Technology Services at SDS, has been recognised in the 2024 Environment 100 for his pioneering work on the development and installation of a smart rainwater recovery system at the Devon & Cornwall Police Headquarters in Exeter. This project, funded by MOSL’s Market Improvement Fund, showcases environmental leadership at a critical public safety facility, highlighting how large-scale, essential infrastructure can be more sustainable.
A key component of this system is the pre-existing SDS GEOlight® surface water attenuation tank, which is crucial because it can hold and store large volumes of rainwater, preventing floods and helping the system manage water more effectively. The GEOlight® tank captures and temporarily stores rainwater from the building’s expansive roof, ensuring that the system can handle heavy rainfall without becoming overwhelmed. This stored water is then transferred via a pump to undergo initial filtration in a pick-up chamber, where large debris is removed, ensuring the system continues to function efficiently.After the initial filtration and flow management, the rainwater is pumped through a series of advanced filters, ensuring the water is clean and suitable for reuse. It is then stored in a 5,000-litre above-ground tank, which serves as the primary reservoir for the system. From this tank, the water is used to flush seven toilets in the building’s gym area, significantly reducing the demand for potable water.
The system’s performance is continuously monitored and optimised using SDS proprietary SYMBiotIC™ and Intellistorm® technologies. These systems track real-time data on water usage, the volume of rainwater collected, and overall system efficiency. By analysing this data, the system can detect performance issues, optimise water use and maximise the environmental benefits of the installation. Additionally, SDS Intellistorm® controls the release rate of water from the attenuation tank into drainage systems and natural watercourses, reducing flood risks by preventing these systems from being overwhelmed.
Dr Neil Sewell received the award at a ceremony held on the 11th September at the NEC, Birmingham, for his project’s achievements.
