Irish Water is to carry out extensive mapping and surveying work on Cork's sewers as part of its €11 million Drainage Area Plans.

Works will involve using CCTV to survey and assess the condition of over 135km of sewers, mapping an estimated 8,000 manholes, and monitoring the wastewater and rainwater flows in the network.

The plans will help improve the wastewater network in Cork City, Ballincollig and Midleton by identifying where urgent repairs are needed. Surveys will focus on key areas like flooding locations, pumping stations and wastewater treatment plants.

Work is to get underway this month.

Sean Twohig, Capital Programmes Regional Lead, said: "This work is part of Irish Water's commitment to protecting Ireland's waterways and coastal areas and ensuring that the wastewater infrastructure is in place to support population growth and economic development. Much of the sewer network is in poor condition due to its age and decades of under-investment. In addition, only a small portion of it has been accurately mapped and assessed to determine its condition.

"Data gathered from this project will allow us to improve the wastewater treatment network across Cork by identifying the areas most urgently in need of upgrading and allowing us to plan our investment so that we can meet the needs of these Cork communities now and into the future."
