Work is progressing apace on King’s Lynn Drainage Board’s new flood storage area to the east of the A149 at the Hardwick roundabout.
The flood storage area will have a total capacity of around 130 million litres (28.5 million gallons), and is designed to allow the board to divert water from Middleton stop drain and Pierpoint drain at times of high flows.
It will then be stored temporarily before discharging the excess water to Middleton stop drain once levels in that watercourse are suitable.
Having the ability to divert water out of these drains during high flow events will lessen the risk of flooding through Hardwick Industrial Estate and residential areas which feed into these watercourses, as well as to farmland and other properties upstream of the A149.
Increasing capacity within this network also offers an opportunity to potentially allow future developments to discharge their surface water run-off to these drains.
Phil Camamile, chief executive of King’s Lynn Drainage Board, said: “The board is committed to continually reviewing the standard of protection provided by its maintained water level management systems, and, where appropriate, carrying out improvement works to decrease the risk of flooding to people, land and property.
“The new flood storage area is the latest example of this, and will improve the standard of protection in a catchment where the residential, commercial, industrial and agricultural properties have an estimated total value approaching £1 billion.”
George Dann, the project engineer, commented: “Construction of the pond represents the culmination of a long period of design and planning works, including archaeological and ecological investigations and discussions with a number of other authorities and local landowners.
When completed the scheme will be a significant benefit to the Board in managing water levels in this part of King’s Lynn and the surrounding countryside.”
The Board’s project manager, Mel Neale, added: “This scheme is progressing well, and the contractor – J E Spence & Son Ltd – is on target to complete the works at the start of November.
“JE Spence are working seven days a week and are experts in their field.
“Predominantly the Hardwick pond is a flood storage area, however the wild flower and grass seeded embankments, combined with the wetlands, will also create a haven for wildlife.”
