SAN MARTIN NORTE is a wastewater treatment plant located in San Martín de Valdeiglesias, within the Comunidad de Madrid, Spain. It serves a small population of 136 residents and has a designed capacity of 2000 m³/day, indicating it is sized to accommodate future growth or seasonal variations. 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 scale. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids before discharge. The treated effluent is likely discharged to a local watercourse within the Alberche River basin, which flows into the Tagus River and eventually reaches the Atlantic Ocean near Lisbon. The plant plays a role in protecting the local aquatic environment and downstream water quality in the Tagus basin.
Environmental context
The plant is situated inland in the Comunidad de Madrid, within the Alberche River sub-basin of the Tagus River watershed. The Tagus River is the longest river in the Iberian Peninsula, flowing westward through Spain and Portugal to the Atlantic Ocean. The Alberche River supports diverse aquatic life and provides water for irrigation and recreation. Proper treatment at SAN MARTIN NORTE helps prevent nutrient and organic pollution that could affect downstream ecosystems and water users.
