Mr. Jerry Grant:

Realistically, in the majority of cases we will end up installing, and we are installing, storm balancing tanks at the inlet of our works so that we can get the plant to cope better with the flows. We consider opportunities whenever there is a road reinstatement project or a road surfacing project by a local authority, for instance. It is very expensive to take storm water out of the sewer system. In general, it is not economic to do so. Our response, in most cases, is to try to deal with it at the plant by installing a storm balancing tank. It means that the tank temporarily overflows when it rains and the water is brought back into the system. That was not typically provided until relatively recently in most plants. It is required in order to deal with Irish conditions.
