Overview
Obidos wastewater treatment plant in Portugal serves 3,000 people with secondary treatment. It discharges 500.19 m³/day and has a designed capacity of 3,300 m³/day, located near the coast.
The Obidos wastewater treatment plant is a municipal facility in Portugal, serving a population of approximately 3,000. The plant is situated near the Atlantic coast, reflecting its coastal setting. It operates under the Portuguese regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, a standard level for agglomerations of this size under EU regulations. It has a designed capacity of 3,300 m³/day and currently discharges 500.19 m³/day of treated wastewater. The plant's location within 10 km of the coast means its discharge may affect coastal water quality. Treated effluent from the plant likely enters a local watercourse that flows into the Atlantic Ocean. The coastal waters off western Portugal support diverse marine life and are important for fisheries and tourism. Proper treatment helps protect these ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into a local watercourse that drains to the Atlantic Ocean along Portugal's western coast. This coastal region features sandy beaches and rocky shores, supporting diverse marine habitats. The area is ecologically sensitive due to its proximity to the ocean, where nutrient inputs can lead to eutrophication and impact water quality for recreational use. Effective secondary treatment reduces organic load and suspended solids, mitigating potential harm to the marine environment.
