E.Coli was found in Barkstone Le Vale by Severn Trent.
Residents in a rural village are currently without a water supply after E.Coli was found in the water.
Severn Trent is currently carrying out testing of the waterworks in Barkestone Le Vale after E-coli was found in the water supply.
The company believes routine maintenance work has affected the system, and has been supplying the residents with bottled water while officers work to fix the problem.
A Severn Trent spokesperson said: “On Friday we were doing some routine maintenance in New Causeway, Barkestone le Vale. Unfortunately this has caused some dirt to get into the water pipe and one of our samples indicated that the water was did not meet the high standards we expect.
"As a precaution, while we disinfect the affected section of pipe with chlorine, we’re asking customers at 30 properties in the street not to drink their water. Only the properties on this section of pipe are affected.
“We’ve been taking samples of the water over the weekend, and once we’re absolutely sure that the water is back to normal, we will lift the restrictions. In the meantime we’ve been providing bottled water for everyone affected and keeping them informed of what’s happening.
"We’re incredibly sorry this has happened - we know that this is a huge inconvenience for everyone affected, but water quality is of paramount importance and we need to make sure the water is back to its normal great standard.”
