Council reports that flooding in Newbridge estate was due to excess rain and demand on sewerage network

Kildare County Council have provided a report on an instance of flooding at Dara Park in Newbridge during August, after a local councillor asked what measures will be put in place to prevent further flooding.

The estate was subject to flooding and sewerage overflow on August 14 after a heavy night of rainfall, and Cllr Seán Power asked for a detailed report on the matter.

The council responded by stating that the problem arose after nearly half of the monthly rainfall for August fell in the space of seven hours, while the sewerage network was also operating at capacity.

"The flooding which took place on 14 August affected a number of locations in Newbridge, two of which were at Dara Park and Lakeside Park," read the report.

"This flooding was as a result of a number of factors, including approx. 30 mm of rainfall over 7 hours (the monthly rainfall for the whole month of August was 65.4 mm) and a sewerage network which is operating at capacity and subject to a number of mis-connections from surface water.

"The Dara Park Flood Relief Scheme was designed to provide protection from flooding from the surface water network and has been working successfully since substantial completion. The flooding on 14 August was caused by the surcharging of the sewerage network, whose remediation was not part of the
Flood Relief Scheme.

"The construction of the Newbridge Eastern Interceptor Sewer will reduce the pressure on the existing sewerage network and its capacity. In the meantime Kildare County Council will continue to carry out schemes to remove surface water from the sewerage network, where possible. The infrastructure issues at Dara Park and Lakeside Park will be raised with Irish Water."
