Gully sensor tech 'requires significant refinement'

Following a trial of sensors that can report when road gullies are getting blocked, a highway authority has said the technology will require further work before being widely used.

In autumn 2016 engineering firm Amey installed new sensor technology into gullies in Hampshire, where it was at the time the county council’s highway maintenance contractor. 

The sensors measured the level of silt and the water level inside the gully, feeding this information back to a control centre managed by Amey via web-based, mapped, visualisation software.

It was said that technology worked well, gullies would only need to be cleansed when they are at risk of flooding, leading to 'a radically different approach' to gully cleansing.

However, both parties have presented the trial as something from which they have learned, rather than an outright success for the new technology.

A Hampshire CC spokesperson told Highways: ‘The County Council is always open to new ideas to help us make the most of the resources we have to look after Hampshire’s roads, such as potential ways to improve our response to adverse weather and flooding.

‘We looked into a trial of gully sensors which offered the possibility of helping us quickly resolve some types of flooding on the roads, by alerting us to blocked gullies; and also to provide data on key factors which affect flooding on the roads, such as silt and water levels in the gullies so we could proactively prevent flooding.

‘This was a useful trial; however we concluded that the technology requires significant refinement before the sensors might be rolled out further across the highways network.’

David Ogden, Amey’s business director for highways, said: ‘Following the results of the pilot, we calculated that we have the potential to reduce the cost of gully cleaning by 20%. This was through better knowledge of the gullies but also by developing an on-demand approach and real-time monitoring.

‘We are now looking to scale up these new approaches to gully cleaning on other accounts, using sensor technology and data analytics.’

The May issue of Highways magazine will contain a feature on the use of ‘smart’ gully technology, covering gully sensors, asset management software and the importance of using information from sensors as part of the bigger picture.

Amey spends almost £1m with social enterprises

A year on from joining the Buy Social Corporate Challenge, Amey has announced that it spent almost £1m with social enterprises in 2017.

The Challenge is an initiative run by Social Enterprise UK that sees companies open up their supply chains to social enterprises, businesses which trade to meet a social or environmental mission.

In 2017, Amey spent £930,000 with social enterprises, following extensive work with Social Enterprise UK to identify new organisations for Amey to work with.

It said work is now under way to secure an even greater spend for 2018.

Head of social impact Emily Davies said: 'Amey’s goal is to create better places to live, work and travel. We do this directly through delivering our services but have the ability to increase our impact – bringing greater social value to communities in which we operate – if we partner with social enterprises in our supply chain.'
