Trainees need to showcompetence carrying outmaintenance on small plants to gain BritishWater’s accreditation
Below: Training covers small packaged sewage plants of up to 1,000 population equivalent
Below:With increasing concerns about the
quality of rivers and streams, it has never been more important to have properlymanaged wastewater treatment plants
As part of the accreditation, trainees need to showcompetence carrying outmaintenance on septic tanks, biological filtration plants, rotating biological contactors, activated sludge plants, submerged aerated filters, biological aerated flooded filters and pumping stations.
director Evangelos Petropoulos said: “It is essential that freshwater quality is protected at all times and to achieve this,wastewater treatment plants require precisemaintenance, so they are always in goodworking order.
Manufacturers like us need toworkwith site maintenance teams that are fully aware of the technicalities of our plants and canmaintain themin perfect condition. Accreditation by BritishWater provides this assurance.”
BritishWater technicalmanager DrMar Batista said: “The performance ofwastewater treatment plants of all sizes can have significant implications for the natural environment.With increasing concerns from UK regulators about the quality of rivers and streams, it has never beenmore important to have properlymanaged plants that provide robust treatment and prevent pollution.
“A lot of hardwork has gone into developing the newtraining forwastewater treatment technicians, raising the bar on service and maintenance across the UK. Iwould like to thank all thosewho have delivered this important training in such a challenging year and congratulate the technicianswho have gained accreditation and had their skills and expertise recognised.”

Prerequisites for certification are recognised qualifications in Electrical Safety andWorking in Confined Spaces alongwith completion of EU Skills’ Safety Health & Environmental Awareness (SHEA)Water scheme.
Technicianswith a certificate that is expiring will need to renewwith the newaccreditation.
Chicken run for Chopper Pump
Ferrier Pumps has brought about a successful solution to a trickywastewater application at a newchicken processing plant in Scotland.
Withwashdownwater containing feathers, faeces and sawdust, achieving the required flowratewas critical, aswas the selection of a pump that could copewith the difficult solids.
As part of its design,which included two screens, pipework, control panels and flowmeter, Ferrier Pumps (established 1981), brought in a submersible Chopper Pump fromLandia, as Peter Ramsay, Sales Engineer, explained:
“Critically,we knewthat if theminimumself- cleansing velocity could not bemaintained for this packaged pumping station, then the solids in the pumped productwould settle out causing blockages”, he said.
“We’d also seen fromprevious experience that the Landia Chopper Pump is extremely effective and reliable – evenwhen having to dealwith very hard-to-handle solids such as feathers.We’ve had no issues at all. It really is the best pump for these challenging applications”.
Operating at 1500 RPM, the submersible Landia Chopper Pump installed by Ferrier Pumps is designedwith its classic external knife systemthat relentlessly chops solids before they get inside the pump’s casing – continuously reducing particle sizes for the benefit of the process.
