The Dublin City water crisis has come about after an exceptionally dry, hot summer. It is not a water shortage, but a question of the water not being able to be treated to an acceptable quality.
Hundreds of thousands of people in Dublin, Kildare and Wicklow are being affected, and the restaurant and hotel business under serious pressure.
The DCC engineers say they don't know yet what the problem is, and UK chemists have been brought in to work on it.
Dublin notoriously has a massive leaks problem, the result of having been a very poor country through much of the 20th century, and also of politicians reluctance to spend money on invisible infrastructure, like water and sewerage, preferring to open roads than treatment plants.Lack of land with water and sewage treatment capacity in the late 1990s was one of the factors driving land and house prices up.

As with food supplies, we operate these days with little or no safety margins. The situation in Dublin seems seriously worrying, potentially damaging to the economy and to health.

Council lab technicians and engineers are at the Ballymore Eustace plant again today running through computer and physical treatment systems in a bid to identify the problem.
Hundreds of thousands of homes and business in Dublin city and county and parts of Kildare and Wicklow are 30 million litres below what is needed to keep taps and toilets flowing after the 10-day old problem.
Production at Ballymore Eustace has been cut by about a fifth.
The supplies are a different colour and turbidity or cloudiness than the system is used to handling.
It is suspected the fine, dry summer followed by periods of heavy rain over the last few weeks has created an unusual balance in the raw water.
Pollution is not an issue and the quality of water making it to taps is not a concern.
Experts have said the issue centres on sediment or treated material that needs to be removed from drinking water floating, or being suspended in treatment tanks, rather than sinking.
