Yorkshire awards contract for wetland-based treatment works

Yorkshire Water has awarded contracts for the construction of an integrated wetland at its Clifton wastewater treatment works to BarhaleDoosan JV building and Stantec

.

The project will create almost 4,000 sq.m of interconnected ponds built on local impermeable clay with more than 20,000 wetland plants from 25 species to remove phosphorus from the treated water before it is returned to the environment. Plants have been selected to promote diverse habitats, with particular attention to creating environments that support bees and other pollinators.

The project is expected to be completed in autumn 2021.
