WFD app shows the water quality at Kilmihil stream is at Poor status due to elevated nutrient concentrations
WFD app indicates that sediment is the significant issue and the pressures are possibly forestry and/or an operational quarry upstream
Licence Register No. A0091-01 Kilmihil
The phosphate is likely to be reaching the river through discharge from UWWTP (Kilmihil Urban Waste Water Treatment Plant). Kilmihil wastewater treatment plant was identified in the EPA initial characterisation as the sole significant pressure on the Kilmihil Stream waterbody
EPA notes that this plant is overloaded (i.e. raw sewage is discharging untreated or partially treated to the river)
The Mountbellew Drainage district is present in this waterbody. Information taken from the WFD app suggests that HYMO is having an impact on the Castlegar_010 ecological status.
The IFI reported issues with management of the drainage districts – untrained drivers who don’t provide plans to fisheries. During the 2014 survey the EPA biologists noted that the river had been resectioned/over-deepened.
The river would appear to be very straight and there are a number of land drains feeding into the main channel
Number of livestock crossing points and drinking points
Mountbellew and Moylough WWTP discharges
Note: Bord Na Mona are not maintaining the silt traps near the Shiven River.
A list of current known locations of emergency overflows on the network to waterbodies (including rivers) has been compiled.
Emergency overflows on the sewer network are located at wastewater pumping stations and can activate in the event of the following failure modes; (a) an equipment failure or (b) power failure or (c) pump blockage.
Where there is a storm water overflow/combined sewer overflow at a pumping which operates under gravity, it can also operate as an emergency overflow under the same failure modes.
These storm water overflow/combined sewer overflows have been also included on the list.
Site surveys, assessments and checking of data is an on-going process and what has been listed is a snapshot and represents the current data that we have.
With regard to agglomeration D0510 the wastewater treatment plant and wastewater pump station are both alarmed. A new alarm system was installed at SW003 (Crooked Wood PS ), which has been operational since April 2021 and is routinely tested . No overflow events have been recorded from the plant in 2021 or from the network pumping station at Crooked Wood since this alarm system has been operational.
