These are several pictures that I took in 2010 during a trip to Tarifa, southern Spain.
It is one of the best spot for wind surf, kite surf and of course for wind energy production.
The WTGs are about 20 years old, but they look like remnants of a faraway past, with their lattice tower and noisy turbines.
Regarding the drainage system, very effective concrete ditches and a complete network of transversal drainage pipes has been used.
Also, the exit of the drainage pipes has been “hidden” using an interesting mix of concrete and local stones.
