Water bosses are set to install a permanent bug-killing, ultraviolet light device at a treatment plant which was at the centre of the cryptosporidium crisis.
Chiefs at United Utilities have revealed that the temporary measures put in place at several Lancashire reservoirs will remain until spring when the new system will come on line.
Mobile UV devices were hurriedly installed at water storage centres at Weeton, Warbreck, Westby, Barnacre, Grimsargh and Hoghton to kill off the microscopic parasite which had got into the water supply. Water was contaminated by the bug supplied from the Franklaw water treatment plant at Catterall, near Garstang.
Now water bosses plan to place a UV device at Franklaw to prevent a similar outbreak which saw people at 300,000 home and businesses forced to boil water for 30 days.
A United Utilities spokesman said: “We will install a brand new ultraviolet device at Franklaw.
“It is just being constructed now and that should be delivered and up and running by April next year.”
