Last phase of Guernsey Water’s St Sampson’s project nears end
THE St Sampson’s wastewater catchment improvements project is nearing completion.
Guernsey Water has been working on the fourth and final phase of the project, which began in 2015.
It is the largest project in the utility’s current business plan. Aiming to tackle a variety of issues, including foul water flooding and environmental pollution following heavy rainfall, the four phases of the project have involved substantial work around the St Sampson’s area.
Guernsey Water’s capital deliver manager Carl Falla said it was likely that at some time throughout the course of the project, islanders would have become aware of the work at some stage.
‘Whether that may have been witnessing the installation of a storage tank under the Bulwer Avenue car park during phase one, following diversions during the replacement and upgrade of a 235m length of sewer in Vale Road during phase two or during the replacement and upgrade of 475m of sewer around La Hure Mare and Summerfield Road as part of phase three,’ he said.
‘The heavy rainfall experienced earlier this year was a real test of the improvements, so we are delighted to report that issues usually experienced in rainfall events less significant than this, such as foul water flooding around the Summerfield road area, were not found to be an issue during this event.’
The latest phase of the project involved the upgrade of the pumping station found on the Southside of St Sampson’s harbour. As the deepest station in the utility’s portfolio, at a depth of 17 metres, significant station refurbishment works were required to ensure the station had greater performance against flooding from increased flows, improved maintainability and greater daily operational resilience against failure.
‘We would like to take this opportunity to thank the public for their patience during these works, as well as all who have helped bring this project to reality, from our own staff, to contractors both on and off island,’ Mr Falla said.
‘We would also like to advise that, although we continue to carry out improvements to our infrastructure to ensure effective drainage for Guernsey, it is still important for islanders to remember that they are all able to help to keep the island’s sewers flowing and assist in the prevention of foul water flooding by only flushing the three Ps – pee, poo and (toilet) paper.’
