IFCA Hears Concerns Over Desalination Plant Proposals
A member of the islands’ Inshore Fisheries and Conservation Authority has raised concerns over Council plans to improve the functioning of the desalination plant on St Mary’s.
The unit takes water from boreholes but these have been contaminated with iron pyrite, which is clogging the filters. It’s reducing output and costing more to produce the water.
The Council announced recently that they’ve designed a new open water inlet pipe, located out to sea, which should get around the problem.
But Tim Allsop told the IFCA meeting that he was worried about the two proposed locations for the work.
He says he’s “extremely concerned” about the first one, at Gap Point, which is in the middle of a colony of sunset cup coral, which is classified as a nationally rare marine species.
And the second location is “probably the most silty area on the island.”
Tim said, “they’ll be cleaning their filters from now to Christmas if they put it there.”
He said he’d passed the information on to the Senior Manager for Infrastructure, Craig Dryden, but added, “I’m not 100 per cent sure if I’m getting through.”
