The water supply for Limerick City comes from the River Shannon and is treated at the Clareville Water Works. There has been a water treatment plant at this location since the 19th Century but it has been upgraded many times since then.
- The treatment plant currently treats and delivers 48,000-50,000 m3/day.
- This is about 2/3 of the capacity of the plant.
- 60% of the water from the plant is consumed by residents of the city, with the remainder supplying parts of County Limerick and County Clare.
- Wastewater from the entire city of Limerick is collected and treated to an appropriate standard before discharging to the River Shannon.
Since 2013, Irish Water is responsible for the provision and operation of water and wastewater infrastructure. Irish Water published its 25 years strategic plan in 2015, which sets out its strategic objectives for the delivery of water and wastewater services in Ireland up to 2040. These are:
- Meet Customer Expectations
- Ensure a Safe and Reliable Water Supply
- Provide Effective Management of Wastewater
- Protect and Enhance the Environment
- Support Social and Economic Growth
- Invest in Our Future.
Many of the awareness raising campaigns around water and wastewater are now conducted by Irish Water at national level.
- An Taisce's Green-Schools Water theme - this programme engages with thousands of schools throughout the country, raising awareness of water conservation in schools and local communities.
- Think Before You Flush campaign, run by Clean Coasts.
- This programme aims to tackle the serious problem of sewage-related litter on Ireland’s beaches and encourages responsible bathroom behaviour to protect the marine environment from pollution.
- “Why Value Water” campaign aims to communicate the message that water is one of our most valuable resources and raise awareness of the fact that it has shaped our landscape, dictated the location of our cities, protected our health and fuelled our economic development in Ireland.
Limerick City and County Council carries out local awareness campaigns on behalf of Irish Water and is currently finalising a Fats, Oils and Greases (FOG) campaign in the city and rural towns where there are issues in the sewer network with regard to build up of FOG.
