After nearly three months of championing new ways of working due to the Coronavirus pandemic, environmental engineering company Land & Water is set to resume the construction of one of four fish passes along the River Severn in Worcestershire on behalf of its client, Kier.
As part of the project, known as ‘Unlocking the Severn’, Land & Water aims to construct a large deep vertical slot for a fish pass at Holt Weir. This is essential for the rare migratory fish, the Shad to travel to their natural spawning grounds. The fish pass will also benefit other migratory fish such as Salmon, Eels and Lamprey. This project is one of the largest river restorations of its kind ever to be attempted in Europe.
The work includes establishing site access and compounds upstream of the weir, the construction of a small slipway and offloading point and the installation of a large temporary dam structure within the river to prevent water ingress into the works area. The large mass dam is being installed from Land & Water’s floating pontoon.
Land & Water’s team will also excavate the bank, using its specialist long reach excavators and tracked dumpers to make working on the bankside easier and safe. Meanwhile, they will oversee permanent solutions in the form of soil nailing and the installation of large-scale legato blocks, using a 100-tonne crane and 16-piece ravestein pontoon to achieve this.
Finally, Land & Water will manage engineering landscaping as part of this project, including erosion protection and amenity improvement of the area. Using special stability calculations to facilitate getting their equipment to site and the team’s unique expertise to deliver an exceptional standard of service.
Funded by the National Lottery Heritage Fund and the European Union LIFE programme, ‘Unlocking the Severn’ will also deliver ambitious heritage, education and science programmes that aim to reconnect eight million people with the river.
Lucy Lee, Contract Manager at Land & Water, says: “We are very much looking forward to getting started on this project again. ‘Unlocking the Severn’ not only benefits the ecological system of the River, it inspires the community to learn about their local environment.
Despite being previously delayed due to the prolonged River Severn Flooding over the winter months, we now have a great chance to take advantage of the drier summer weather and lower river levels, making work easier and safer for our team.”
As part of its commitment to the wellbeing of its staff, Land & Water has prioritised the development of safe working practices, in accordance with Government guidelines, to ensure that work can be carried out without posing a risk to its employees or the public.
Programme Director Jason Leach says: “It is important to us that we have the social distancing rules in place to protect our staff and the general public, whilst ensuring as little disruption as possible. We have worked with leading construction company Kier so that we can adapt to the current challenging conditions, delivering the project in a safe and timely manner.”
As Land & Water continues to adapt its protocols on site, Unlocking the Severn marks one of many restoration projects undertaken by the engineering firm, highlighting its commitment to enriching and enhancing the environment. Working closely with the Canal and River Trust to develop the most cost effective and appropriate solution, Land & Water is proud to work collaboratively to oversee an exceptional project.
About Unlocking the Severn:
Unlocking the Severn is being run by the Canal & River Trust, Severn Rivers Trust, Environment Agency and Natural England. The project is one of the largest river restorations of its kind ever to be attempted in Europe, with funding from the National Lottery – awarded through the National Lottery Heritage Fund – and the European Union LIFE programme.
State of the art fish passes will be installed on four navigation weirs along the River Severn, starting this spring in Worcester at Diglis and Bevere, following fish passage improvements that started last year at two sites on the River Teme.
Unlocking the Severn will also deliver ambitious heritage, education and science programmes that aim to reconnect eight million people with the River. This includes working with community groups along the river, over 6000 school children, and creating opportunities for hundreds of volunteers.
