Householders across South Lanarkshire have raised concern over discoloured water coming from their taps in recent weeks.
Dozens of people, especially across Hamilton, Blantyre, Bothwell, East Kilbride, Cambuslang and Uddingston, have reported a brown tinge from their taps with others taking to social media to seek advice.
Some have even contacted Scottish Water to report the problem and sought bottled water, which is in short supply in shops across the county, as they are wary of drinking from the tap.
One concerned Bothwell resident told Lanarkshire Live : "My tap water has been running brown, on and off, for around week now.
"I've had to source bottled water from the shops as I don't my children to drink from the tap. Bottled water is really hard to come by just now and I can only assume it is a mix of the recent good weather and the discolouration of the tap water at present.
"It's not ideal really and does not look very pleasant at all."
It is understood the problem is linked to "seasonal naturally occuring manganse levels" within the Daer Water Treatment Works in Elvanfoot, Biggar, that serves Lanarkshire.
A burst on a six inch main at Low Waters Road in Hamilton has also caused discolouration in the network for customers.
A Hamilton homeowner added: "There is something very wrong with the water in Silvertonhill and surrounding areas of Hamilton, water coming out brown from taps for weeks now.
"One resident saying even his dog is turning away from his water bowl choosing to drink from puddles instead."
Scottish Water say samples are being taken regularly to ensure they are complying with "legislative standards" and that the water can be used as "normal."
A spokesman for Scottish Water said: "Customers supplied from Daer Water Treatment Works may intermittently experience a brownish tinge to the water.
"This is due to seasonal naturally occurring manganese levels present in the source water for this works.
"While the treatment process is effective at removing bacteria and chemical impurities from raw water it does not entirely remove manganese.
"The levels of manganese continue to reduce and stabilise however some customers may still experience a brownish tinge to the water.
"Scottish Water will continue to carry out work at Dear Water Treatment Works to reduce the manganese levels and the associated discolouration issues currently being experienced in the water supply by some of our customers.
"Samples of water are being taken regularly to ensure that Scottish Water complies with the legislative standards set in The Public Water Supplies (Scotland) Regulations 2014.
"Results for these samples comply with the above regulations for all other analysed parameters. The water can be used as normal."
