Overview
SIGoeENZA wastewater treatment plant serves Sigüenza, Castilla-La Mancha, Spain, treating wastewater for approximately 8,863 residents. The plant discharges into the local watershed, contributing to the Henares River basin.
SIGoeENZA is a wastewater treatment plant located in Sigüenza, a municipality in the province of Guadalajara, Castilla-La Mancha, Spain. The facility serves a population of about 8,863 people, placing it in the small-to-medium agglomeration category under Spanish and EU regulations. As a plant serving fewer than 10,000 population equivalents, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC) requirements for secondary treatment. The plant is expected to meet the directive's standards for biological treatment and nutrient removal where necessary to protect receiving waters. The plant's treated effluent is discharged into the local water system, which drains into the Henares River, a tributary of the Jarama River, which ultimately flows into the Tagus River and then to the Atlantic Ocean near Lisbon. The Henares River supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
The plant discharges into the Henares River basin, part of the Tagus River watershed, which flows westward across Spain and Portugal to the Atlantic Ocean. The Henares River provides habitat for native fish species and supports riparian ecosystems. Downstream, the Tagus River is a major water resource for agriculture and urban supply, making effective wastewater treatment critical for maintaining water quality and ecological balance in the region.
