Skibbereen Regional Water Supply Scheme

ON THIS PAGE
Contact us

Irish Water was required to propose and advance remedial actions to resolve water quality issues in the Skibbereen region and remove three water supplies from the Environmental Protection Agency’s (EPA) Remedial Action List. 

In partnership with Irish Water, we planned, designed and managed the construction of a rationalised regional water supply scheme centred on the treatment of drinking water at two upgraded water treatment plant sites. This will ensure a safe, secure and reliable source of drinking water supply to over 10,000 people in the region.

The historic public water supply in the Skibbereen region is derived from five separate water sources and treatment plants. There was an insufficient level of treatment at three of these plants and consequently these supplies were listed in the EPA’s Remedial Action List.

Solution

Through the development of concept designs and cost benefit analysis, we identified the need to develop a rationalised regional water supply scheme centred on the treatment of drinking water at two existing plants. This then allowed the decommissioning of the remaining three existing plants.

Applying business information modelling (BIM) processes, we designed the upgrades of the retained water treatment plants using 3D design models.

Comprehensive water sampling, jar testing and THM formation potential analysis were carried out by our team to ensure the designed enhanced coagulation, flocculation and chlorination processes would sufficiently remove the pre-cursors to disinfection by-products. We proposed ultrasonic algae control to reduce the effect of algae on the treatment process.

Our team designed an extensive expansion and enhancement of the existing water supply networks to facilitate the bulk transfer of water to the supply areas where plants were being decommissioned. Robust site and route selection processes, allied with extensive environmental studies and appraisals, were critical in successfully completing statutory planning and compulsory purchase order processes.

Construction works on the €21 million capital project commenced in 2019 and were completed in February 2022.  We administered the construction contract on behalf of Irish Water and provided site supervision services throughout. The three problematic public supply schemes were successfully removed from the EPA’s Remedial Action List in Q4 2021.
