SWIMMING POOLS PUT TO THE TEST The Institute for the Management of Sport and Physical Activity has announced a new award to put swimming pools to the test. Following on from the National Pool Safety Award which resulted in a large number of pools putting themselves forward to be assessed against British Standards, the new award seeks to assess pools against the European Standard EN15288. The award provides a practical approach to the assessment of a pool with a visit and one day audit with an independent expert.
AUSSIES GO GREEN Australian company

MORE FUN IN THE POOL Increasingly popular in European pools, gush showers are now available in the UK for the first time. The FitStar Wave from Hugo Lahme provides a gush of water which is a design feature for any pool. The Wave gush shower is manufactured in stainless steel 316 Ti and powered by a high- performance pump. A soft starter feature is available as an option for the Wave gush shower and causes the water to start flowing more slowly before the maximum gush. Visit

LEISURE CENTRE POOL SET TO SAVE £4,000 A YEAR WITH ABB DRIVE
A leisure centre in Sittingbourne will save £4,000 a year on the costs of air handling for its swimming pool following a trial with an ABB low voltage AC drive.
The Swallows Leisure Centre has three pools in its pool hall, including a 25 metre main pool. The centre is operated on behalf of the local authority by Serco Leisure, which was concerned by the energy use of the air handling unit in the upper pool area. To deal with a condensation problem in the pool hall, this AHU was being run 24 hours a day, 365 days a year, with no control over its output. To improve this situation, Serco asked ABB Drives Alliance member Mid Kent Electrical to investigate the application and determine any savings that could be made. Mid Kent’s Russel Kimpton says: “We already carry out motor and pump work for Serco at several of the leisure centres they operate locally. Serco asked their usual contact in our motor department if we could quote for fitting drives to their existing systems.”
To assess the application, MKE monitored the power being consumed by the existing 22 kW supply fan in the AHU over a period of one week, revealing that the average power consumption of the fan during the period was just less than 19.5 kW.
Trials at the Sittingbourne pool could also cut C02 production dramatically
The second stage of the trial involved replacing the star/delta starting system with a 22 kW ABB standard drive for HVAC. Running at full speed during the day, this was set to run at 30 Hz between ten twenty in the evening and six twenty in the morning. This was monitored over the same period as the direct- on-line system, giving an average power consumption of 14.84 kW. With an electricity cost to the leisure centre of 10p/kWhr, running the AHU fan unregulated would cost just over £17,000 per year and be responsible for around 92
tonnes of CO2 per year. By contrast, operating it with the ABB drive would cost £13,000 a year, a saving of just over £4,000 per annum. It would also cut equivalent CO2
production to 70 tonnes a year. This would give a payback period of well under one year.
Says Kimpton: “There is scope for further savings during the day. Once the full time drive is installed, its speed could be scaled back in say 5% increments to a point just before we start to see the condensation problem again.”
As well as the upper pool hall AHU, there is another AHU in the lower pool hall and one in the gymnasium that could also potentially benefit from ABB drives.

LONDON ZOO UNVEILS NEW ALLIGATOR CLEAR PENGUINS’ POOL
London Zoo has unveiled the largest penguin pool in Britain, which will soon house a 200-strong breeding colony.
Some 65 of the world’s most at- risk breeds have already moved into their new home – and they are enjoying crystal clear water thanks to Aligator Systems who provided water ionisation techniques to purify
water by killing algae and bacteria. The 1,200 square metre pool is four times bigger and three times deeper that the Zoo’s old pool and holds 450,000 litres of water. The Microtech-Aligator Water Purification System was installed by Marine Aquaculture.
The six ionisation chambers will prevent algae growth in the new pool, which will reflect in the clarity of the water.
The new pool will have underwater viewing areas where visitors can see the birds swim. Zoological Society of London (ZSL) said penguins were under threat from climate change, fisheries and pollution.
The introduction of Humboldt and Macaroni penguins, as well as the Blackfooted and Rockhopper penguins which were already at the zoo, aims to highlight the research of ZSL’s ‘penguinologist’ Dr Tom Hart. “The pool is much bigger and deeper, and they can exhibit more of their natural behaviour,” Dr Hart said. “They look really happy.”
The new enclosure also has rocks and more space which closely resembles their natural environment.
