Some people relying on private water supplies in rural Carmarthenshire say they ran out of drinking water weeks ago due to the dry weather.
Carmarthenshire council said people affected could get in touch for help.
Ms Rees’ home is usually supplied with water from a well in her garden but it started to run out in June.
"We fill up buckets of water and we only flush the toilet with those buckets of water, maybe once or twice a day."
About 1% of the population of England and Wales use a private water supply, according to Welsh Water, and they do not have to pay a water company for it.
Welsh Water said it was providing bottled water for councils to "distribute to customers whose private water supplies are currently affected".
Carmarthenshire County Council said anyone whose private drinking water source has dried up should get in touch for advice, with drinking water available at pick-up points.
Farmers Geoff and Sue Freeman are draining a pond to provide their 200 sheep with water after their two wells dried up, and are relying on the goodwill of family and friends to bathe.
Mr Freeman said: "You feel uncomfortable being in their house because you are actually dirty and that is not a very pleasant feeling."
