BARX Wastewater Treatment Plant, Barx, Comunitat Valenciana, Spain

BARX is a former wastewater treatment plant located in Barx, a municipality in the Comunitat Valenciana region of eastern Spain. The plant served the local population and was designed with a capacity of 1500 cubic meters per day, reflecting its role in managing municipal wastewater for a small community. Its coastal location, within 10 km of the Mediterranean Sea, placed it in a sensitive environmental zone where treated effluent discharge requires careful management to protect marine ecosystems. Although the plant is now closed, it originally provided secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent above 2000, ensuring that organic matter and suspended solids are reduced to acceptable levels before release into the environment. The plant's proximity to the Mediterranean coast means that any discharge would have entered a coastal water body, potentially affecting local marine habitats and bathing waters. The region's drainage ultimately flows into the Mediterranean Sea, which supports diverse marine life and is an important economic and recreational resource for Spain. Proper wastewater treatment is critical to prevent nutrient pollution and protect water quality in this coastal environment.

The plant is situated in the Comunitat Valenciana, a region along the eastern coast of Spain, with drainage flowing into the Mediterranean Sea. The Mediterranean coastal zone is ecologically sensitive, supporting seagrass meadows, coral formations, and diverse fish populations. Treated effluent from coastal plants must meet stringent standards to avoid eutrophication and protect bathing water quality, which is vital for tourism and local fisheries.
