Unwanted insulators have been put to use off Playa Hermosa as part of an artificial reef built by the Instituto Costarricense de Electricidad. The insulators are porcelain and are of the type that are seen holding up high-tension wires.
The reef is in water of some 25 to 28 meters, well out of the way of swimmers. The first section is six meters in diameter and made up of six insulators.
The reefs in the Pacific have been taking a beating from the
shrimp trawling nets that are dragged along the bottom.
The material has been in the sea for just six months, but the state power company said that natural growth already has been seen.
The material was put there by divers who work for the company at some of three hydro projects, the firm said. But first the material was tested in a law to make sure there would be no unforeseen consequences, said the company.
The company estimates that by placing the material there, the growth of the reef has been advanced from 100 to 150 years because coral grows slowly.
