Limerick's diverse landscape and climate present specific challenges for Drain and Sewer Services. Many areas, particularly lowlands, feature luvisol soils and poorly draining gleys, which can lead to seasonal waterlogging and increased pressure on drainage systems. Older properties across Limerick, from city-centre homes to suburbs like Dooradoyle and Raheen, often rely on ageing clay or cast-iron pipes. These older materials are highly susceptible to corrosion, cracks, and invasive tree root intrusion, causing frequent blockages and leaks.
Furthermore, Limerick experiences increased winter rainfall and more intense storms, especially in areas near the River Shannon and coastal regions. This heightened precipitation can overwhelm existing drainage infrastructure, leading to backups and potential flooding. Hard water from the Shannon can also contribute to mineral buildup, further exacerbating pipe blockages over time.
