Council Takes The Plunge And Saves £60k On Energy Costs With ABB Drives


Liverpool City Council is saving £60,000 a year on energy costs at five of its swimming pools following the installation of ABB variable-speed drives on filtration pumps and air handling units. Faced with rising energy costs and the need to trim budgets, the council approached ABB authorised value provider Central Group for help in cutting the energy use at its swimming pools. The council’s maintenance manager says: “We had an energy conservation report done on one of our pools by an independent company which had recommended ABB variable-speed drives.” Central Group investigated the pumping set up at the swimming pool. The two filtration pumps were originally run in a duty/standby configuration. Pumping rates were increased as more people entered the pool. Central suggested using the pumps in a parallel pumping scheme that would cut energy use.


Gianfranco Colangeli of Central says: “At first the council was sceptical of the proposed scheme. We suggested a trial to prove that it could work and they agreed. “We logged the energy use of the pumps beforehand - we then installed two new ABB drives. Our predictions indicated a 10-15% saving, but logging the energy use we found that the drives made a 35% saving, with a payback of around six months. This was all with no change in the flow rate or water pressure.”

Dolphin Mobility Ensures Disability Swimming Course Goes Ahead


Dolphin Mobility is celebrating its 25th anniversary by giving something back to the community. Throughout the UK, members of the Dolphin Group of franchises have been making donations to individuals or charitable organisations in their area. As part of this celebration, the Poole and Chobham branches have kindly loaned an i-swim pool lift to Bournemouth Collegiate School. This is to help James Daly, a marine veteran, and Tobias Gutteridge, a serviceman who suffered a spinal cord injury during

operational duties, organise and take part in the STA Level 2 Award in Aquatic Teaching – People with Disabilities (QCF) course. According to James Daly, the course would have been impossible to conduct without the lift as volunteers from the British Limbless Ex-Service Men’s Association (BLESMA) were due to take part as pupils. He explained: “We needed to get the volunteers, who are ex-service men or women with a physical disability, in and out of the pool safely. Without the generosity of Craig and the team at Dolphin Mobility, the course would not have taken place.” The course has been run by Lynne Robshaw, a fully qualified STA tutor. She said: “Being able to confidently operate this type of equipment is integral to each student successfully gaining the necessary qualification to work with disabled


swimmers. As none of the candidates had previously used any sort of hoist or lifting equipment, the fact that Dolphin loaned us such a versatile lifting solution is tremendous. Once instructors have completed the course, they will be able to work with children and adults with varying levels of physical, learning and mental disabilities, all of which can affect their ability to swim safely.


“The i-swim pool lift is extremely user friendly and the feedback we have received from instructors operating the lift, and the people being lifted, has been extremely positive. We are very grateful to Dolphin for all their help and support.”

also installed low occupancy switches, which cause the drives to run the motors at even lower speeds when few people are using the pool or when the pool is closed. “We had budgeted for 45 Hz,” says Colangeli, “but we can go as low as 30 Hz.”


Since the initial installation, ABB drives have been retrofitted into four other swimming pools, for water pumps and air handling units. With a total of 20 drives over the five sites ranging from 7.5 to 18 kW, the project is saving £60,000 a year, with a payback of around two years.
