Overview
Rib de Moinhos wastewater treatment plant in Portugal serves approximately 105,000 people. Located near the coast, it operates under the EU Urban Waste Water Treatment Directive.
Rib de Moinhos is a wastewater treatment plant in Portugal, serving a population of around 105,000. The plant is situated near the Atlantic coast, reflecting its role in managing municipal wastewater for a medium-to-large agglomeration. As a Portuguese facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale, with potential tertiary requirements if the discharge is into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a facility sized to handle the wastewater from its service population. The regulatory framework ensures that the plant meets European standards for effluent quality. The proximity to the coast suggests that treated wastewater may be discharged into coastal waters, subject to stringent environmental controls. The plant's discharge ultimately reaches the Atlantic Ocean, contributing to the marine environment along Portugal's southwestern coast. This region supports diverse marine life and is important for local fisheries and tourism. The plant's operation is critical for protecting coastal water quality and maintaining ecological balance in the area.
Environmental context
The plant discharges into the Atlantic Ocean along Portugal's southwestern coast, a region characterized by upwelling ecosystems that support rich marine biodiversity. The receiving waters are part of the broader North Atlantic basin, which is ecologically sensitive due to its role in nutrient cycling and as a habitat for migratory fish and seabirds. Effective wastewater treatment is essential to prevent eutrophication and protect coastal water quality.
Frequently asked questions
Rib de Moinhos is located in Portugal, near the Atlantic coast at coordinates 37.996 N, -8.883 W.
The plant serves approximately 105,000 people, classifying it as a large agglomeration under EU regulations.
Given its coastal proximity, treated wastewater from Rib de Moinhos is likely discharged into the Atlantic Ocean, subject to EU standards for marine discharge.
As a Portuguese plant, Rib de Moinhos operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 15,000 population equivalent, and tertiary treatment if discharging into sensitive areas.
For a plant of this size in Portugal, secondary treatment is standard, with possible nutrient removal if the receiving waters are sensitive to eutrophication, as per EU directives.
