Murla Wastewater Treatment Plant, Comunitat Valenciana, Spain

The Murla wastewater treatment plant is located in the municipality of Murla, within the Comunitat Valenciana region of eastern Spain. This facility was designed to handle the wastewater needs of the local community, with a capacity of 500 cubic meters per day. The plant is currently closed and no longer operational. As a secondary treatment plant, Murla would have provided biological treatment to remove organic matter and suspended solids, meeting the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for smaller agglomerations. The directive mandates secondary treatment for discharges to freshwater and estuaries from populations under 10,000, which aligns with the scale of this facility. The plant's treated effluent would have been discharged into a local watercourse, likely a tributary of the Girona River or directly into the Mediterranean Sea via the coastal drainage network. The region's Mediterranean climate and proximity to the coast make proper wastewater management essential for protecting both freshwater resources and marine ecosystems.

The plant is located inland but within 50 km of the Mediterranean Sea, in the Marina Alta comarca. Its treated effluent would have drained into the Girona River system, which flows into the Mediterranean near Denia. This coastal area supports diverse marine life and is part of a sensitive ecological zone where nutrient inputs can contribute to eutrophication. Proper treatment is critical to protect seagrass meadows and coastal water quality.
