ROWP Salard Statia de epurare Salard Hodos - Wastewater Treatment Plant in Hodoș, Romania

ROWP Salard Statia de epurare Salard Hodos is a municipal wastewater treatment plant located in Hodoș, a village in Sălard commune, Bihor County, Romania. The plant serves a population of 665 and operates with secondary treatment, which is the standard for small agglomerations under Romanian and EU regulations. With a designed capacity of 750 m³/day and a current discharge volume of 68.73 m³/day, the plant operates well below its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to have secondary treatment. Although this plant serves fewer than 2,000 people, it still meets the secondary treatment standard, reflecting Romania's alignment with EU environmental norms. The treated effluent is discharged into local watercourses that eventually drain into the Crișul Repede River, a tributary of the Körös River system, which flows into the Tisza River and ultimately the Danube River and Black Sea. The plant's operation helps protect the local watershed and downstream aquatic ecosystems from untreated sewage pollution.

The plant discharges into small streams that feed the Crișul Repede River, part of the Tisza River basin. This watershed supports diverse aquatic life and is important for regional biodiversity. The treated effluent contributes to maintaining water quality in the downstream rivers and the Black Sea ecosystem.
