New water systems planned for Essex and Suffolk under future supply plan
Infrastructure projects aim to support water needs and tackle supply shortages
Plans to develop new water systems have been proposed for Essex and Suffolk as part of the Water Resource Management Plan 2024 (WRMP24).
These steps are intended to address forecasted water shortages in two seriously water-stressed areas.
Planned developments in Essex
By 2027, Linford Water Treatment Works will be built to improve the treatment of water from an existing borehole and a new borehole.
Additionally, the Langford and Langham Water Treatment Works are scheduled to receive nitrate removal processes.
This follows concerns about longer-lasting elevated nitrate levels in river water observed during autumn and winter due to farming practices.
Suffolk projects
New water systems are also in development for regions in Suffolk. A pipeline connecting an existing well near Bungay to a water treatment works aims to expand capacity and is set for completion by 2030.
The plan includes the construction of compact treated water reservoirs in Hartismere and Northern Central Water Resource Zones. These reservoirs will provide a short-term backup for a few days of supply, adding resilience to Suffolk’s water system against demand challenges.
Plans for a Lowestoft water reuse plant, expected by 2030, would treat wastewater to high standards before discharging it into a river.
The treated water could then be reused after additional preparation at an existing treatment facility. Another reuse scheme in Caister has been proposed as a longer-term solution needed by 2045.
Regional pipeline connectivity
A set of new pipelines, slated for completion by 2028, will connect the Blyth, Hartismere, and Northern Central Water Resource Zones.
This infrastructure is designed to enable the movement of surplus water to areas in need, helping to ensure consistent supply across the region.
Potential alternative
A winter storage reservoir in Suffolk may be considered instead of certain reuse systems. Final analysis in 2026 will determine if this reservoir, capable of collecting water during heavy winter rainfall to increase local supply, can be completed earlier than planned.
These proposed projects form part of a broader approach to managing water resources and coping with increased demand, environmental commitments, and climate change impacts.
