MALTON STW - North Yorkshire Wastewater Treatment Plant, United Kingdom

MALTON STW is a wastewater treatment plant located in North Yorkshire, England, serving a population of around 22,806. Situated on Derwent Road in the York Road Industrial Estate, Huttons Ambo, the facility is part of the region's municipal wastewater infrastructure. As a medium-sized agglomeration, MALTON STW is subject to the UK's water quality regulations, which derive from the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for populations between 10,000 and 150,000, with more stringent tertiary treatment in sensitive areas. The plant's compliance with these standards ensures adequate treatment before discharge. The treated effluent from MALTON STW likely discharges into a local watercourse, which eventually drains into the River Derwent and then into the Humber Estuary. The Humber Estuary is a major ecological feature supporting diverse aquatic life and migratory birds. The plant plays a key role in protecting these downstream environments from pollution.

MALTON STW discharges into the River Derwent, a tributary of the Humber Estuary. The Humber Estuary is a large coastal plain estuary that supports important fish populations and migratory bird species. The plant's treatment helps maintain water quality in this ecologically sensitive system, which is vital for both wildlife and human activities such as fishing and recreation.
