VALSEQUILLO Wastewater Treatment Plant, Valsequillo de Gran Canaria, Canarias, Spain

VALSEQUILLO is a wastewater treatment plant located in Valsequillo de Gran Canaria, in the Canary Islands, Spain. It serves a population of approximately 2,155 residents, making it a small-scale facility within the region. The plant is situated near the coast, reflecting the island's geography and the need for careful management of treated effluent. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal, ensuring a high quality of effluent before discharge. The plant has a designed capacity of 6,000 m³/day, with a current discharge volume of 241.11 m³/day, indicating ample capacity for future growth. The treated wastewater is discharged into the local environment, likely into coastal waters given the plant's proximity to the sea. The Canary Islands are ecologically sensitive, with unique marine ecosystems that benefit from the advanced treatment provided by this plant. The facility plays a key role in protecting the surrounding waters and supporting the island's environmental health.

The plant discharges into the coastal waters of the Atlantic Ocean near the eastern coast of Gran Canaria. The island's marine environment supports diverse aquatic life, including seagrass meadows and coral formations, which are sensitive to nutrient pollution. Advanced treatment helps minimize the impact on these ecosystems, preserving water quality for tourism and biodiversity.
