That's according to Neil Smyth, the Asset Operations Lead at Irish Water.
Demand for drinking water has increased by up to 25% on many supplies across Cork.
At the same time, due to the dry weather and high temperatures, water source levels are dropping.
All supplies across the county are seeing increased demand, particularly in the west and north of the county.
Schemes under the most pressure at present include those serving Clonakilty, Rosscarbery, Timoleague, Courtmacsherry, Bantry, Durrus and Kilcrohane and all areas in between.
In the north of the county, Kilbrin, Freemount, Liscarrol, Milford, Cecilstown, Newmarket and Kanturk are most at risk.
Speaking to RedFM news, the Asset Operations Lead at Irish Water, Neil Smyth, said that the current weather is leaving West and North Cork particularly vulnerable:
"In Cork we have with 180 water supply schemes. Some supplies are very robust, and we have the headroom to meet extra demand. But some areas, particularly West Cork, and in the north of the county where sources are a little bit more vulnerable to this type of weather and where demand is higher: West Cork tourist locations, also agriculture. We're seeing increases of 25% and 30% above the norm."
