After a wetter than expected summer, the rain has turned to the advantage of the Costa Blanca – with the area’s reservoirs now bursting with water supplies.

This means good news for the many overseas property owners in the area, whose homes will now hold a better guarantee of water supply even if next summer is a dry one.

Popular southern Costa Blanca province Alicante is the home of three large reservoirs, at Guadalest, Beniarres and Amadorio, which have all filled up rapidly – with water reaching 81 per cent of capacity at Guadalest.

Holding between them a total of 37 cubic hectometres of water, the region could now receive a new burst of property investment, with buyers likely to be encouraged by the guarantee of water supplies in such a dry area.

But despite the burgeoning reservoirs, government officials have urged caution, telling homeowners to continue being prudent with water use.

Water is a bigger issue in Spain than at home in the UK – where wet summers are becoming common – with southern Iberia attracting many with its sunny climate but at times experiencing the downside of prolonged dry periods.
