The Do Not Consume drinking water restriction in place on the Achill Public Water Supply, which included adjoining group water schemes, has been lifted with immediate effect.
Irish Water say the water quality sampling has confirmed that the water is now safe to drink following a reduction in demand to normal levels and reduced temperatures in the raw water coming from the lake to the water treatment plant.
The Do Not Consume notice on the supply was issued on Friday, 7 August, following consultation with the HSE due to elevated levels of aluminium in the water supply. Following consultation with the HSE, Irish Water and Mayo County Council are advising customers that the drinking water can now be consumed as normal.
Irish Water’s Ger Greally, has thanked the residents, businesses and visitors to Achill who were affected by this notice for their patience and cooperation until demand and temperatures dropped to normal levels.
Some upgrade works have taken place at the Acorrymore Water Treatment Plant to ensure that if demand rises to an unsustainable level along with a rise in temperatures that the plant will shut down allowing both Irish Water and Mayo County Council time to assess the situation and put plans in place to prevent a further exceedance.
All reservoirs on the island have also been cleaned. Customers may experience some intermittent outages this evening and over the weekend as full supply returns to the network following the reservoir cleaning. Meetings are also scheduled between Irish Water and Mayo County Council to discuss longer term solutions to this problem.
Business customers will receive a 40 per cent rebate on the cost of the supply of water to their businesses for the duration of the do not consume notice and this will be back dated to August 7, 2020.
