The Yorkshire Water project will see 4,000 sq m of interconnected ponds created on a natural slope.
This will then be planted to create a habitat of wetland plants that remove phosphorus from treated water before it is returned to the environment.
Millions of litres of water will be treated naturally by the 25 different plant species, totalling over 20,000 plants across the site.
Plants have been carefully selected to promote diverse habitats, with particular attention given to creating environments which support bees and other pollinators to increase biodiversity.
Michael Housby, lead project manager at Yorkshire Water, said: “This is the first project of its kind in Yorkshire and we’re pleased to welcome BarhaleDoosan JV to the project with Stantec.
“Once completed, the integrated wetland will provide a range of environmental benefits, including reducing reliance on energy-heavy treatment processes, which forms a key part of Yorkshire Water’s ambitious aim to achieve carbon net zero by 2030.”
Chris Mathers, project delivery lead, BarhaleDoosan JV, said: “This is a significant project that uses organic processes to deliver a sustainable approach to treatment and does so with minimal environmental and physical impact. ”
The project is expected to be completed this autumn.
