Hartlepool STW is a wastewater treatment plant serving the coastal town of Hartlepool in Tees Valley, England. The facility handles wastewater from a population of around 126,914, placing it in the large agglomeration category under UK regulations. As a UK plant serving over 100,000 people, Hartlepool STW is subject to the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. These regulations require secondary treatment as a minimum, with tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in megalitres per day or similar units), indicating a substantial infrastructure to manage the region's wastewater. The treated effluent from Hartlepool STW is discharged into local watercourses that flow into the North Sea. The North Sea is a biologically productive marine environment supporting diverse fish stocks, seabird colonies, and marine mammals. The plant's discharge contributes to the overall nutrient load in the coastal zone, which is managed under the UK's Marine Strategy Framework Directive to maintain good environmental status.

Hartlepool STW discharges into the North Sea via local streams and the Tees Bay. The North Sea is a shallow, nutrient-rich sea that supports important fisheries for species such as cod, haddock, and herring, as well as seabird colonies and seal populations. The coastal waters near Hartlepool are influenced by industrial and urban runoff, making effective wastewater treatment critical to maintaining water quality and protecting marine ecosystems.
