The River Wey can be navigated by boat, on natural and man-made sections, along the ‘Wey and Godalming Navigations’. These navigations were constructed under Acts of Parliament in 1651 and 1760. In 1935 Surrey County Council made improvements along the River Wey, to reduce flood risk and maintain navigation, by installing a series of weirs.
Today the navigations are owned and operated by the National Trust. The Environment Agency is responsible for maintaining the navigation and 18 weir structures.
The River Wey weirs refurbishment scheme focuses on 7 of these weirs, which require priority refurbishment and replacement.
The River Wey weirs refurbishment scheme is a partnership project between the Environment Agency, National Trust, Surrey County Council, Guildford Borough Council, Woking Borough Council, Elmbridge Borough Council, and landowners.
How the scheme works
The River Wey weirs refurbishment scheme includes the detailed design, refurbishment or replacement of 7 weir structures at;
- Millmead, Guildford
- Stoke Mill, Guildford
- Bowers Mill, Guildford
- Broadmead Weir, Woking
- Newark Mill, Woking
- Walsham Weir, Ripley
- Hamm Oils Mill, Weybridge
The scheme is designed to maintain the River Wey’s navigation (water) levels, but also complement the River Wey flood alleviation schemes. The design meets current safety standards and is sympathetic to its navigation heritage, by reusing some original components.
Many of the weirs are located in environmentally designated areas, so the scheme also aims to enhance the river’s biodiversity by improving fish and eel passage.
The 7 refurbished weirs are designed to last for the next 70 years.
Following site investigations, and the development of environmental assessments, the design of new weirs has been completed. The designs will be shared with partners, before construction starts.
The total cost of the scheme will be close to £8million. This includes the design, construction and maintenance of the weirs and weir structures.
The Environment Agency is funding the scheme using Capital Grant.
What happens next
The construction contractor is to be appointed, and all licenses, consents and planning approvals are to be obtained.
The most suitable time for construction in the river is between 1 April and the 31 October. This includes the summer period when river levels are at their lowest, and daylight hours are longest. Some work on the river banks, may be allowed over the winter period.
We aim to complete refurbishment of at least 3 weirs by 31 October 2018, with all 7 weirs to be completed by 31 October 2019.
