Guernsey Water has been shortlisted for a national award in recognition of its sewer renovation work in the grounds of Havilland Hall.
The 21st Annual UK Society of Trenchless Technology (UKSTT) dinner and award ceremony took place on 24 April and saw Guernsey Water narrowly miss out on the award for small renovation, instead receiving a highly commended certificate.
Guernsey Water was nominated alongside some strong national water providers such as Wessex Water, for work it carried out in the grounds of Havilland Hall, Guernsey’s biggest privately-owned estate. Entrants were judged on a range of criteria including project management, innovation, environmental awareness and impact on the community.
The renovation work at Havilland Hall was carried out on sewers installed some 85 years ago which posed a number of logistical issues. Access to the site was difficult and open excavation would have caused major damage to the landscaped grounds.
Stephen Langlois, Director for Water Services for Guernsey Water, said: “By using trenchless technology it meant there was little disruption to the daily workings of the estate, as equipment was set up and disassembled quickly, safely and with minimal noise disruption.”
Guernsey Water worked alongside contractor Environmental Techniques to carry out the sewer renovation work over a 12-day period which also involved importing plant and equipment into the island.
Mr Langlois said: “As we were acutely aware of the disruption this work could have caused, we liaised with the estate owners nine months prior to the work. The project was completed on time, and now means a key arterial sewer will be in place for many more decades to come.”
