Vol. 276 No. 7

Ceisteanna—Questions. Oral Answers. - Plastic Filter Bed.

51.

asked the Minister for Local Government if the plastic filter bed which is in operation in one public sewage treatment works on an experimental basis has proved to be more efficient than older methods.

The experimental filter bed referred to by the Deputy has proved satisfactory for the purpose for which it was installed, which was to augment the capacity of an overloaded conventional works. The circumstances at this works do not permit the making of a direct comparison between the conventional methods and the new filter media.

The Minister cannot make a direct comparison—in other words, he cannot say whether the new system is more efficient than the old one?
