Overview
Heist wastewater treatment plant serves Knokke-Heist, Belgium, treating wastewater for approximately 33,900 residents. Located in West-Vlaanderen, it operates under the EU Urban Waste Water Treatment Directive.
Heist wastewater treatment plant is located in Knokke-Heist, a coastal municipality in West-Vlaanderen, Belgium. The facility serves a population of approximately 33,900 people, classifying it as a medium-sized agglomeration under European Union regulations. As a Belgian plant, Heist operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this size. The directive also requires more advanced treatment if the discharge enters sensitive areas, which is relevant given the plant's coastal proximity. The plant's treated effluent likely discharges into the North Sea via local waterways, given its location within 50 km of the coast. The receiving environment supports diverse marine life and is an important ecological zone for the Southern Bight of the North Sea.
