Overview
ALCOI wastewater treatment plant serves Cocentaina, Comunitat Valenciana, Spain. It handles a population equivalent of 215,778 under EU Urban Waste Water Treatment Directive standards.
The ALCOI wastewater treatment plant is located in Cocentaina, within the Comunitat Valenciana region of Spain. It serves a population equivalent of 215,778, classifying it as a large agglomeration under EU regulations. The plant is situated in an industrial area, reflecting the region's mixed urban and industrial wastewater management needs. As a large agglomeration, the plant is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive mandates secondary treatment as a minimum, with tertiary treatment required for discharges into sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating its scale of operation. The treated effluent is discharged into local water bodies that ultimately drain into the Mediterranean Sea. The Comunitat Valenciana region features several rivers and coastal areas that support diverse aquatic ecosystems. Proper treatment at this plant helps protect downstream water quality and marine environments from nutrient pollution and other contaminants.
Environmental context
The plant's discharge contributes to the local watershed, which flows through the Serpis River basin and eventually reaches the Mediterranean Sea near the Costa Blanca. This coastal area supports seagrass meadows and fish nurseries, making nutrient control critical. The region's semi-arid climate means river flows can be low, increasing the ecological impact of treated effluent on receiving waters.
