Scottish Water have been given the go ahead to block 145 kilometres of drains as part of peatland restoration work at the Afton reservoir near New Cumnock. 

The work, at the Afton water treatment works, will help to reduce carbon emissions, improve water quality and improve the wildlife habitat of the area.

Peatland bog can have moisture levels of up to 95 per cent in its natural state.

As this is not suitable for most developments, drainage works are often carried out.

Around 170 km of surface drains were identified around the Afton site, around 9km south of New Cumnock. Of these drains, 145km will be blocked in a bid to restore the peatland.

Drainage has significant impact on peatland’s ability to store carbon, results in poorer water quality and affects the often unique wildlife and biodiversity of a bog.

While peatland is often described as one of the most effective carbon sinks in the world, a ‘degraded’ bog can actually release carbon dioxide into the atmosphere.

A spokesperson for the Crichton Carbon Centre, based in Dumfries and Galloway, which carries out peatland restoration works across south-west Scotland, said: “Over thousands of years peatlands have sequestered carbon which is now locked away and stored in the form of peat.

“Peatlands in poor condition are at risk of releasing this carbon back into the atmosphere.”

Nadarra Ecology were commissioned to carry out a survey as part of the Afton Catchment Peatland Restoration Feasibility Plan.

A report by East Ayrshire Council planners stated: “The primary benefit of restoration is in relation to climate change and storage of carbon, along with the provision of an ‘internationally important habitat’, improved water quality and reduced flood risk.”

The reservoir and treatment works serve around 45,700 people, including one hospital and 80 care homes.

The application was approved by East Ayrshire Council planners under delegated powers.
