The Metropolitan Police has given an environmental award to Interserve in recognition of the work that it has done creating an environmentally efficient soil filtration system used to help solve crimes in London.
The environmental award was made in December 2018 by Neil Grange, Head of Environment and Sustainability at the Metropolitan Police.
The system Interserve developed is not only more user-friendly, but crucially recycles water rather than using an “open tap” system as per the older model, saving 100 litres of water per minute. The new system also allows for material to be re-sieved, so any evidence possibly missed can be identified.
Material that requires sieving is dispersed into two tanks before being agitated by water. The soil is then diverted into sieves of various sizes. When the diluted soil passes through these sieves soil particles of various sizes are captured, which are sorted onto drying trays and examined.
Richard Aylett, Operational Manager for the Metropolitan Police Operational Support Group, said:
“I am extremely impressed by the way Interserve responded to the task. Their solution is much more efficient than the old system we used. We typically use the sieving technique once every couple of years. It is invaluable when searching for tiny fragments of bone that could identify human remains.
“The system has played an important role in cold cases where new evidence has come to light that requires investigating gardens or land for minute clues.”
Mel Morgan, Special Events Accounts Manager from Interserve, leads the Interserve team of 26 people at the Metropolitan Police’s Merton Park station. The team is responsible for everything from setting up equipment for the Metropolitan Police through to traffic management, building signage, plumbing and the electrics.
“I’m delighted the team’s hard work has been recognised by the Metropolitan Police environment award. This is a great example of how Interserve’s engineering expertise has improved a series of processes, that is not only delivering more effective outcomes for the Police on crime scenes but also is making a significant contribution to reducing water consumption, making its operations more sustainable.”
