Pumping sites on a bog could mean that drainage operations are active
Mott MacDonald’s Remedial Environmental Impact Assessment Report highlighted a number of sites with drainage pumps
Example: Bellair North
During periods of heavy rainfall, when the pump P15-10 is pumping, flooding has occurred downstream of the silt pond that discharges through outfall SW37. Bord na Móna has mitigated this issue by switching off the pump in periods of wet weather and consequently flooding occurs to the production areas.
Example: Ballybeg
There are no historical records of any flooding events or any historical flooding of the site, however from local knowledge flooding of the peat production area has occurred where bog pumps have failed to operate or where pumps have not been able to meet the demands imposed by extreme rainfall events.
Example: Ticknevin
There are no historical records of any flooding events or any historical flooding of the site, however from local knowledge flooding of the peat production area has occurred in Ticknevin where existing surface water pumps have failed to operate, as well as more locally where drains have become blocked internally
