'Progress' made in dealing with water parasite in Devon
But South West Water says more work will be needed before it can lift the boil notice
South West Water says some progress is being made to remove the remaining traces of cryptosporidium from the water supply in Devon - but more work's still needed.
In a statement on social media, the firm's said:
"Over the past week we have cleaned our reservoirs and flushed the network several times in an attempt to remove the remaining traces of cryptosporidium.
"While our water quality samples are showing progress in recent days, further intense work is needed to fully remove any contamination.
We are sorry this is taking time, but we need to be absolutely confident we have fixed this problem before we can safely lift the boil water notice.
"This morning, we have completed cleaning of the water mains after the Alston water supply area and leading into the Hillhead Supply Tank and fitted filters at the Boohay Supply Tank which will help prevent cryptosporidium entering the Kingswear part of the network.
"Aggressive scrubbing is ongoing"
"We are also undertaking a similar process to install filters at Hillhead Supply Tank over the coming days.
"We are also strengthening our interventions by putting ultraviolet light treatment at Hillhead this week which will also further prevent any future recurrence of this issue.
"Further aggressive scrubbing and cleaning of mains pipes is ongoing and our teams will continue to work around the clock until the job is done and we can safely lift the boil water notice.
"We want to reassure customers and businesses that we are doing everything we can to restore supply to the quality our customers expect and deserve and put interventions in place to prevent this from happening again."
