Stanmore Marsh Wetlands opens officially after restoration project benefits from Flex MSE®

The Mayor of Harrow, Cllr Margaret Davine, officially opened Stanmore Marsh Wetlands on Wednesday 28 th June 2017, the culmination of a two-year project to restore the marsh back to its former glory using Flex MSE®.

A portion of Former Mayor of London Boris Johnson’s Big Green Fund, which allocated £900,000 for projects across London that would improve local green spaces, funded the huge restoration alongside Thames Water.

The Stanmore Marsh site, over four hectares, was once full of wildlife and a source of enjoyment and leisure activities for the local community. However, over the years it became neglected, no longer acting as a green space for floodwater alleviation, increasing the incidence of localised flooding. The project created approximately 400m of new footpaths and up to 400m 2 of wetland. This allowed for providing well over 3,000m 3 of additional floodwater storage. Several hundred metres of water habitats and environments, made up of a network of small wetlands and ditches, were also revitalised utilising the award-winning Flex MSE ® system, for riverbank repair and restoration. The use of this system has allowed for an immensely stable riverbank that blends into the native vegetation and reduced the carbon footprint and cost of the project.

Using MSE (mechanically stabilised earth) principles alongside geotextile technology, the combination of nonwoven Flex MSE ® bags and patented interlocking plates allows for strong and easy-to- install geomodular block structures.

Vicky D’Souza, Stanmore Marsh project officer at Thames21, said,
“Volunteers have been invaluable in helping to restore this site, with activities such as planting bulbs, carrying out pond improvements and removing litter. They are a vitally important part of this project, because they can act as champions and continue to make improvements to ensure Stanmore Marsh remains a great place for people and wildlife to enjoy.”

With expert collaboration between organisations such and credit to Atkins Global, Ebsford Environmental, Thames Water & Kier, Harrow Council, and Thames21 were able to execute a scheme that exceeded all expectations.

Flex MSE® Vegetated Wall System is suitable for hydroseeding, live staking/planting and brush layering, and is water & root permeable with a design life of 120+ years.
