Low Carbon Solution to Waste Water Management

Wetland nursery from the air

Salix grew tens of thousands of native wetland plants for a Integrated Constructed Wetland (ICW) to treat wastewater as part of a Yorkshire Water Wastewater Treatment Works (WwTW).

River Elwy, Pipeline Protection, North Wales

Working for Bournemouth & West Hants Water, Salix were appointed as Main Contractor to undertake 2km of bioengineering works to stabilise the shoreline of a new reservoir.

Afon Gwydol Embankment

Afon Gwydol embankment

Works were required to repair an eroding railway embankment adjacent to the river. This resulted in the embankment encroaching into the river, causing erosion problems on the opposite bank belonging to a local farmer.

Papworth Reedbeds

Papworth wetlands and reedbeds

After a competitive bid process, Salix designed and built a tertiary treatment reedbed for Anglian Water at their Papworth STW. Salix partnered with Pete Worrall of Penny Anderson Associates and a unique design approach was developed.

Salwarpe Reedbed

Salix successfully tendered for a pilot project to improve marginal vegetation along the River Wandle. The project formed part of a wider scheme to reintroduce water vole to the river.

Upper Lake, Perton

A two hectare area of open water had extensive embankment erosion due to massive populations of Canada Geese

A two hectare area of open water had extensive embankment erosion due to massive populations of Canada Geese which created public health & safety issues.

Grand Union Canal

Chaser on river restoration

The project aim was to restore a wetland area on the banks of the Grand Union Canal for the benefit of wildlife and the fishery. The scheme design ensured that no material was taken off site and that particular focus was on creating suitable habitat for Water Voles and amphibian species such as Newts.
