ITTRE Wastewater Treatment Plant, Ittre, Belgium - Secondary Treatment Facility

ITTRE is a municipal wastewater treatment plant located in Ittre, within the Brabant wallon province of Belgium. The facility serves a population of approximately 2,394 residents and is part of the region's wastewater infrastructure managed under Belgian and European regulations. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,600 m³/day and an average discharge volume of 427.93 m³/day, the plant operates well below its capacity, indicating ample headroom for future growth or seasonal variations. The treated effluent is discharged into local watercourses that eventually drain into the Senne River basin, which flows through the Brussels region and ultimately into the Scheldt estuary. This contributes to the protection of downstream aquatic ecosystems and supports the ecological health of the Scheldt basin.

The plant discharges into local streams that are part of the Senne River catchment, which flows through central Belgium before joining the Dijle and eventually the Scheldt River. The Scheldt estuary is an ecologically important area that supports diverse aquatic life and migratory bird populations. The secondary treatment provided by ITTRE helps reduce organic pollution and nutrient loads, protecting the downstream water quality in this densely populated region.
