POPPY HILL STW - Henlow, England Wastewater Treatment Plant

POPPY HILL STW is a wastewater treatment plant located in Henlow, Central Bedfordshire, England, serving a population of around 19,200. The facility is part of the UK's wastewater infrastructure, managed under the Water Industry Act and the Urban Waste Water Treatment (England and Wales) Regulations, which transpose the EU Urban Waste Water Treatment Directive. For agglomerations serving between 10,000 and 150,000 people, UK regulations mandate secondary treatment as a minimum standard. Plants of this scale typically employ biological treatment stages such as activated sludge or trickling filters to meet consent conditions set by the Environment Agency. The treated effluent from POPPY HILL STW is discharged into local watercourses that ultimately drain into the River Great Ouse catchment, which flows into The Wash, a large estuary and nature conservation area on the east coast of England. The plant plays a key role in protecting the water quality of these sensitive downstream environments.

POPPY HILL STW discharges into the River Great Ouse catchment, which flows into The Wash, an ecologically important estuary supporting diverse birdlife and marine habitats.
