Case Study on the installation of an environmentally sewage treatment solution consisting of a BMS Blivet WWTP and a Wetland.

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.  Part of the brief was installing an environmentally sustainable long lasting solution.

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 outfall, 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 visits the plant once per year to perform mechanical maintenance.

Final Effluent Standard: BOD 25mg/LSS 35mg/L, COD 125 mg/lTotal Phosphate (P) 2 mg/l & Orthophosphate (OP) 1 mg/l.

Environmental Friendly Solution: The installation of a BMS Blivet Package Sewage Treatment System in conjunction with a wetland is a leading example of an environmentally friendly sewage treatment system.  The Blivet itself is a market leading sewage treatment solution in regards to low power, foot print, construction costs with an expected lifetime of 30+ years.  The Wetland is a reliable low energy method to polish the effluent to an excellent standard in a sustainable way, without intensive further mechanical treatment.  It also offers a home to wildlife such as frogs, ducks and birds.  A common problem with wetlands that do not have a sewage treatment system before them, is that they can quickly become overloaded with solids and BOD.  This can also lead to bad odours. The Blivet pre-treats the sewage in an efficient and low impact aerobic way preventing the build of solids and also prevents any odour problems.  Indeed, as the Blivet is completely pre-fabricated and the most compact available it can be easily added before an existing wetland.  The BMS Blivet combined with a wetland is leading solution for any eco-conscious communities, developers or government authorities and as part of an ‘Eco Village’.  BMS can work with you to design a custom solution.  Please contact us: [email protected] or phone:+353433326100.
