A small scale environmental disaster

In the olden days fields in Alicante were irrigated by flooding them with water. Tanks, depositos, were dotted all over the countryside to collect rainwater and some were filled by pumping water from wells. We have a deposito in our garden but, long before we got here, the former owners had painted the inside with that turquoise blue paint and turned it into a splash pool. Bigger than a paddling pool but much less grand than a swimming pool. Some 5575 gallons or 22.3 cubic metres of water.

Most summers we've filled it up but, being basically a big bucket, it soon started to fill with leaves and dust. Maggie wanted something better and when the legislation changed to say that people should not pour gallons of water into depositos which could not be recycled we no longer had the choice.

This summer Maggie finally did something. We had someone install a pump and filter. As luck would have it one of the inlet or outlet junctions at the very bottom of the pool isn't watertight and water is dribbling out. We decided the leak wasn't significant and went ahead with the filling. Last night the deposito was finally full. This morning the water level had dropped 30cms. Inspecting the tank now there are damp patches around a lot of the base. My guess is that, as well as the leak from the new pipework the drilling, to fit the various inlets and outlets, has weakened the structure of the tank and it is no longer watertight.

Literally money down the drain.
