Thurles Sewage Crisis – Summer Stench, River Pollution And Flooding, As Upgrade Must Wait Until 2028

Residents of Thurles face further years of sewage concerns, unpleasant summer odours and potential flooding, with a major upgrade of the town’s ageing wastewater network not expected to begin construction until 2028.

Uisce Éireann has confirmed that a planning application is being prepared for improvements involving new and upgraded sewers and pumping stations.
Subject to planning approval, procurement and no further delays, construction is anticipated to commence in 2028.
For a town that has endured years of concerns about sewage discharges into the River Suir, flooding and foul smells, the announcement raises serious questions about why a permanent solution remains so far away.

Much of Thurles operates on a combined sewerage system, where household sewage and rainfall travel through the same underground pipes towards the wastewater treatment plant.
During heavy rainfall, increased volumes can overwhelm parts of the network, potentially resulting in untreated sewage mixed with storm water being discharged through overflow outlets.
Blockages and inadequate drainage capacity can also contribute to flooding, with Friar Street among the areas where problems have been highlighted.
Uisce Éireann acknowledges that the existing wastewater infrastructure is inadequate and requires upgrading to address environmental compliance issues and alleviate flooding.

One of the most troubling aspects of this longstanding problem is the condition of the River Suir as it flows through Thurles.
For years, concerns have been raised about sewage discharges, pollution, algae and foul odours, particularly around, Thurles Shopping areas and close to The Source Arts Centre.
During warmer summer months, the stench can become particularly unpleasant for residents, shoppers, businesses and visitors.
Higher temperatures, reduced river flows and stagnant water can make unpleasant smells more noticeable, while lower water levels provide less dilution for pollutants.

Local reporting in 2024 highlighted complaints about untreated sewage entering the River Suir itself near Thurles Shopping Centre, alongside concerns about offensive summer odours.
The River Suir should be one of Thurles’s greatest natural attractions, rather than a recurring source of environmental concern.

Will the €8.59 Million Liberty Square Upgrade Have to Be Dug Up Again?
Another important question must now be answered; will the already upgraded eastern half of Liberty Square, part of a Phase 1 project with a recorded budget of approximately €8.59 million, have to be excavated again to accommodate the proposed wastewater improvements?
The completed scheme included extensive streetscape improvements, new paving, road surfaces and underground infrastructure.

Reports have also highlighted complaints about sewage-type odours emerging from drains in the completed section of Liberty Square.

With further wastewater works now being planned, residents and businesses are entitled to know whether these projects have been properly coordinated:-

1. Will recently completed paving and road surfaces have to be disturbed again?
2. Were the wastewater deficiencies identified before the Liberty Square redevelopment commenced?
3. Could further excavation lead to additional public expenditure and disruption for local businesses?

There is currently no confirmation that the completed section will require excavation, but Uisce Éireann and Tipperary County Council should clarify this before the wastewater project proceeds.
Such coordination is particularly important while plans for the remaining western half of Liberty Square are also progressing.

Years of Problems, More Years of Waiting
The need for wastewater improvements has been recognised for considerable time.
The Thurles and Environs Local Area Plan 2024–2030 identifies the importance of separating foul wastewater from surface water.
Uisce Éireann commenced detailed design and investigation works in 2025 to determine the improvements required.
However, a construction start in 2028 does not mean the problems will be resolved that year. Completion could extend considerably beyond that date.
Meanwhile, residents deserve information about interim measures to reduce sewage overflows, flooding and persistent odours.

Thurles Deserves Better
The proposed investment is welcome, but the people of Thurles have waited years for meaningful improvements.
Protecting the River Suir, addressing the summer stench and reducing the risk of sewage-related flooding must remain priorities.
Equally important is ensuring that future underground works do not unnecessarily damage recently completed, publicly funded improvements to the town centre.
Thurles deserves a clean River Suir, a reliable sewerage network and proper coordination between major public infrastructure projects.

After years of problems and millions already committed to upgrading Liberty Square, residents deserve clear answers, responsible planning and a permanent solution.
