PELAHUSTAN Wastewater Treatment Plant, Pelahustán, Toledo, Castilla-La Mancha

PELAHUSTAN is a wastewater treatment plant located in Pelahustán, a municipality in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a small population of 1,320 residents, reflecting its role in a rural or semi-rural setting. Its location on Senda Viriato places it within the local infrastructure network. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal or other tertiary steps, ensuring high-quality effluent. The plant discharges a reported volume of 76.00 units of treated wastewater. The treated effluent from PELAHUSTAN likely enters a local watercourse that feeds into the Tagus River basin, the largest river system in the Iberian Peninsula. The Tagus flows westward through Spain and Portugal, eventually reaching the Atlantic Ocean near Lisbon. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Tagus watershed.

The plant discharges into a local stream that is part of the Tagus River basin. The Tagus River flows through central Spain and Portugal, supporting diverse aquatic life and providing water for agriculture and urban use. The advanced treatment at PELAHUSTAN reduces nutrient loads and pollutants, helping to maintain ecological balance in the downstream environment, which includes sensitive habitats along the river corridor.
