A new wastewater treatment plant and reservoir is to be developed in south Donegal.

Irish Water recently signed a deal with Coffey Water to upgrade the Owenteskna Public Water Supply.

The new plant will benefit around 4,000 customers covering the area west of Killybegs including Kilcar, Carrick and Glencolumcille.

The scheme is supplied from Lough Nalughraman, an impounded upland source which provides a good quality raw water supply. The lake water receives minimal treatment congsisting of screening and disinfection. As a result, the Owenteskna/Kilcar Water Supply scheme is on the Environmental Protection Agency's (EPA) Remedial Action List (RAL).

The contract will see the construction of a water treatment plant on a new site at Owenteskiny Townland, Carrick, in the vicinity of the existing disinfection house. The new treatment plant will comprise a robust flocculation, coagulation and filtration process, followed by UV disinfection to mitigate against the risk of contamination.

The new treatment plant has a design output in 2MLD and the contract also includes for treated water storage at the treatment plant and for source protection works and access improvements to the source.

Works are due to commence on site early in 2017 and are expected to be completed in one year.
