CALA D OR, Cala d'Or | Spain Wastewater

Overview

CALA D OR wastewater treatment plant serves Cala d'Or in the Balearic Islands, Spain. It handles a population equivalent of 23,875 and is located near the Mediterranean coast.

The CALA D OR wastewater treatment plant is situated in Cala d'Or, a coastal town in the municipality of Santanyí on the island of Mallorca, part of the Balearic Islands, Spain. The plant serves a population equivalent of 23,875, placing it in the medium agglomeration category under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the discharge enters sensitive areas, which coastal zones often are. The plant's treated effluent is discharged into the Mediterranean Sea, given its proximity to the coast. The Balearic Islands rely on healthy marine ecosystems for tourism and biodiversity. The discharge contributes to the nutrient load in coastal waters, which can affect seagrass meadows and marine life if not properly managed.

Environmental context

The plant discharges into the Mediterranean Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The coastal waters around Cala d'Or support diverse marine habitats, including Posidonia oceanica seagrass meadows, which are crucial for carbon sequestration and nursery grounds for fish. Proper treatment is essential to prevent eutrophication and protect these ecosystems.
