Northern Gas Networks has won a Brownfield Briefing Award for its land remediation work at a gas holder site in Redheugh, Gateshead.
NGN picked up the Best In Situ Treatment Award for the project, delivered in partnership with Sweco UK Limited and Geo2 Remediation Limited for its novel approach to cleaning up historical land contamination..
As part of the wider site demolition project, NGN used solar powered pumps to remove more than 4,500 litres of toxic coal tar from an underground tank which had been built during Victorian times. Through the use of only solar power, the gas distributor saved the equivalent of more than 18 tonnes of CO2 and approximately £6,000 in running costs in the initial six months of operation.
This follows on from the project winning the Sustainability Award at the Chartered Institute of Water and Environmental Management Tyne and Humber Branch Annual Awards in July.
Neil Whalley, Environmental Strategy Manager at for Northern Gas Networks, said: “As part of our Environment Strategy launched in June 2018, we are exploring a variety of different methods to be sustainable.
“Through this use of only solar power, we saved the same amount of CO2 as the average car driving non-stop for 29 days as well as a reduction in noise, compared to traditional petrol generators, and vehicle movements associated with waste disposals.
“At NGN we’re committed to reducing our environmental impact on the customers and communities that we serve, and where possible make a positive impact.”
NGN is now exploring the use of solar power on future projects.
For around 100 years gas holders were a vital part of the local gas supply system, responsible for supplying gas to thousands of people across the country. However, advances in technology and the enhanced capability of the modern-day gas network mean that gas holders are no longer in use.
NGN is aiming to dismantle 23 of the region’s gas holders by 2021 as part of continued investment in modernising the gas network. A short film has also been produced to commemorate NGN’s gas holders.
