Dubliners could be drinking recycled sewage water in the next few years. Irish Water is looking into ways to prevent shortages in the city.
The reclaimed water would be drawn from treatment plants and could be used for both irrigation and human consumption.
It's just one idea in a new report published in the Irish Independent, which examines the options for providing clean water over the next 25 years.
Ossian Smyth,a Green Councillor in Dún Laoghaire-Rathdown, believes Ireland's wastewater treatment system is "far from in order", adding that the idea is "very far-fetched".
Dublin is highlighted as the biggest problem area and the report noted that shortages have become more common in recent years.
A pipeline pumping water from the River Shannon into the city has also been suggested.
Recycling watewater is already used in countries like Australia and parts of the US but Irish Water says they've yet to make a final decision on whether they'll introduce it to Dublin.
