UWWTP Stamboliyski is a municipal wastewater treatment plant located in the Polatovo district of Stamboliyski, Plovdiv Province, Bulgaria. It serves a population of around 21,617, classifying it as a medium agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local water bodies that eventually drain into the Maritsa River basin. As a Bulgarian facility, UWWTP Stamboliyski operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. Bulgaria has transposed these requirements into national law, and the plant is subject to permits issued by the Ministry of Environment and Water. The plant's discharge contributes to the Maritsa River system, which flows through Bulgaria, Greece, and Turkey before reaching the Aegean Sea. This river basin supports diverse aquatic life and is important for regional agriculture and biodiversity.
