Address: Ardclough, Co. Kildare, Ireland.
Brief: To upgrade Ardclough WWTP from a settlement tank and a malfunctioning pumped peat treatment bed to a new WWTP encorporating a new 250 PE BMS Blivet Package Sewage Treatment Plant, a new wetland & civil works.
BMS Design Details: The wastewater treatment plant (WWTP) pre upgrade only consisted of a settlement tank and a malfunctioning pumped peat bed. BMS finalised the site design incorporating a a BMS BL3000 Blivet Package Sewage Treatment Plant after the existing settlement tank, the design of a new wetland in the curtilage of the existing peat bed tank, along with new manholes, pipework, a new site shed, fencing, levelling, a new outfall, sampling point and CL804 finish. The Wetland design was done with Feidhlim Harty from FH Wetlands.
BMS Construction/Installation Details: BMS cleared the whole site in conjunction with our civil's partner, FIMA Developments. The excavation of the peat bed along with its disposal in a licensed hazourdous material disposal facility, the sealing, earthworks, pipework and planting of wetland plants proved the biggest task. BMS installed a new outfalls, a control panel including a GSM Dialout facility, an ultrasonic flowmeter and flume and an 'all in one' package treatment plant in the form of a BMS BL3000 Blivet Package Sewage Treatment Plant. The project included new outfall headwalls, the laying of a water main, fencing of the site and a Cl804 finish on the site and on the access road.
BMS Operation/Maintenance Details: BMS maintained the plant until handover, which was three months after practical completion. The plant worked very well from the start achieving very high quality effluent. As the plant was installed during the Winter there was a significant lag time until the wetland began to grow. It is now thriving as can be seen from the pictures above. BMS had a six month maintenance period on the wetland.
Final Effluent Standard: BOD 25mg/L, SS 35mg/L, COD 125 mg/l, Total Phosphate (P) 2 mg/l & Orthophosphate (OP) 1 mg/l.
