Irish Water is responsible for the treatment and distribution of drinking water and the provision of sewer collection systems in Cork City and County.

Lot 1: A number of Combined Sewer Overflows (CSOs) have been identified for removal from the sewer network in Mallow as they are currently in breach of the Urban Wastewater Treatment Directive and are the subject of an European Court of Justice (ECJ) infringement notice.

The removal of these CSOs will necessitate new trunk sewers to be constructed within the town.

Lot 2: As part of the implementation of a Water Conservation Project for the city, watermains in the network have been identified for rehabilitation. These include watermains that:

 Are not suitably responsive to active leakage control measures;
 Have water quality issues;
 Have reached the end of their service life; and
 Have insufficient hydraulic capacity and are impacting on the efficient operation of the existing network.
New sections of water mains have also been identified which will link existing strategic water supplies and provide security of supply to Cork City.
