Western Costa del Sol Urges Prudence as La Concepción Drops to 63% Capacity

La Concepción Reservoir Capacity Drops to 63 Percent

By Costa del Sol News 25 September 2026 1 min read

Water authorities call for continued vigilance across Marbella and Estepona as the main reservoir drops to 63 per cent capacity after a scorching summer.

Civic authorities and water management bodies have renewed calls for sensible consumption across the western coastline as regional storage levels dip below peak thresholds. The key freshwater reservoir of La Concepción, which supplies drinking and municipal water to households from Torremolinos through Marbella to Estepona, has slipped to 63 per cent capacity following sustained high temperatures throughout August and early September.

Seasonal Pressure on Coastal Reserves

After a comparatively parched spring season, water usage spiked considerably during the busy summer tourism surge, drawing heavily on local catchments. Despite occasional rainfall during earlier winter phases, regional water boards note that prolonged heatwaves across Andalusia have accelerated natural evaporation and strained baseline supplies. Although current reserves remain adequate for day-to-day community demands, hydraulic planners warn against complacency.

Practical Guidelines for Homeowners

Town halls across the western Costa del Sol are urging homeowners, holiday renters, and urbanisation managers to practice water stewardship. Residents are encouraged to review smart drip-irrigation schedules for private gardens, repair leaking community swimming pool fittings, and refrain from washing outdoor patios or private vehicles with mains potable water during peak daytime hours. Local utilities continue to monitor daily extraction rates to ensure residential service runs uninterrupted through autumn.

Long-Term Infrastructure Enhancements

Regional authorities continue to advance complementary resilience measures, including upgrades to regional desalinisation and greywater reclamation networks in surrounding coastal districts. As autumn unfolds, officials remind both long-term residents and incoming seasonal guests that sustainable water use remains the most effective safeguard against statutory supply restrictions in the months ahead.
