“The upgrade of our desalination plant will be the biggest investment in the Island’s water resources for a generation.” – Helier Smith
We have published our priorities for the second year of our strategy to 2030 and confirmed our water charges for 2027, as we continue to invest in the infrastructure needed to secure the Island’s water supply in a changing climate.
Following a summer that highlighted the importance of resilient water supplies in Jersey and across Europe, we are continuing our investment programme to strengthen the Island’s water security and adapt to hotter, drier conditions expected in the years ahead.
A key priority for 2027 will be the start of a significant upgrade to our desalination plant, representing the biggest investment in water resources since Queen’s Valley Reservoir was commissioned more than 35 years ago.
To support investment in the Island’s water supply infrastructure, we have confirmed our water charges for 2027. From 1 January, average households can expect to pay an extra 8 pence per day for their water, which is equivalent to an additional £2.55 per month or £30.60 per year.
The £26 million upgrade of our desalination plant will increase its output by up to 50%, strengthening Jersey’s ability to maintain water supplies during prolonged periods of low rainfall and drought. The investment forms a critical part of our plans to adapt to changing weather patterns, which are expected to place increasing pressure on water resources and increase the risk of water shortages in the years ahead.
We will also continue preparations for future PFAS requirements with pilot trials and treatment technology evaluations, alongside investments in water infrastructure that further strengthen operational resilience.
Helier Smith, Chief Executive Officer for Jersey Water commented:
“Safe, reliable water is something every household and business depends on every day. Recent summers have demonstrated how much pressure prolonged dry weather can place on the Island’s water resources, and climate change means we expect these challenges to become more frequent in the future.
“We are very aware that any increase in household bills comes at a difficult time for many customers, and we remain committed to providing support and assistance to those who need it. We have worked hard to keep customers’ bills as low as possible, while balancing the need to make essential investments that will help ensure Jersey has a resilient and secure water supply for the future.
“We have a responsibility to plan ahead. The upgrade of our desalination plant will be the biggest investment in the Island’s water infrastructure for a generation and will play a vital role in helping us maintain supplies during drought conditions.
“When we published our 2030 strategy last year, we were clear that increases in water charges would be necessary to support the investment required to secure Jersey’s long-term water supply. The increase will enable us to deliver that investment, strengthening the Island’s resilience and helping to ensure a safe, reliable water supply for generations to come.”
We have published our business plan for 1 October 2026 to 30 September 2027 on our website, so customers and the wider community can see how these investments will help secure water supplies and deliver long-term benefits for households, businesses and the Island in the years ahead.
Details of our water charges for 2027 and the support available for customers are also published on our website.
