Diö waterworks is receiving new process equipment and electronics to improve reliability after roughly 50 years. It supplies Diö, Liatorp and Stenbrohult, but the municipality says customers can use water normally during the work. Completion is planned for mid-December 2026.
What happened?
The plant opened in the mid-1970s and parts of its technology are outdated. Electrical and process equipment will be replaced this autumn. Brief pauses in treatment may occur, but the reservoir is expected to contain enough treated drinking water for customers. No customer water shut-off has been announced for the work.
Location
Diö, Liatorp, Stenbrohult, Kronobergs län
Impact and significance
Modernisation is intended to reduce failures and stabilise production, but does not increase groundwater availability. More reliable machinery can improve operations without creating a new raw-water source. The plant is also being prepared for a possible future transfer pipeline from Älmhult, but that connection is not a completed part of this autumn's work.
Background
Water supply involves raw water, treatment, storage and distribution. The reservoir buffer allows brief treatment pauses without immediate customer interruption, but cannot rule out every unexpected fault. If an operational disruption occurs, the municipality's latest notice takes precedence over this planned-work summary.
Latest update
Work continues through autumn and is expected to finish in mid-December. Residents of Diö, Liatorp and Stenbrohult currently need not change normal water use because of the renovation. Follow-up should check the timetable and any operational notices. Water-quality or shut-off information should always be verified directly with the utility.
