11 April 2013 — A $17 million redevelopment of Beatty Park, an aquatic centre in the City of Vincent, near Perth, will deliver an energy saving of 5000 megaWatt hours a year.

The redevelopment, which started in September 2011 and was completed last month, had a main focus of reducing the facility’s environmental impact and engineering its operations towards responsible use of resources.

Mayor Alannah MacTiernan said creating “a leaner, greener facility was paramount in the design and engineering – and this new facility is a game-changer”.

Ms MacTiernan said a major feature was the new geothermal heating system that draws hot water from deep underground to heat all of the facility’s swimming pools. A geothermal bore more than 1000 metres deep taps a hot aquifer, producing water temperatures of 48.5 degrees Celsius at the well head. The water is re-injected into the aquifer at 750 metres so as to not compromise the volume and heat of the aquifer.

“And with an eye to the future, the council approved a larger bore than was necessary for the primary task of heating the water in all pools,” she said.

“We are now doing the business case for heating the air in the indoor pool area and also piping the water to our administrative and community facilities 300 m down the road.”

Insulated below-ground pipe work will transmit hot water to each facility, with the geothermal energy transferred to each building’s heating system via plate heat exchangers installed in the existing plant rooms.

In addition to supplying 100 per cent of Beatty Park’s pool heating requirements, the proposed expansion would save an additional 36 per cent of the energy currently used at the three facilities.

Other features include:

  • The installation of 150 250W Suntech solar modules, which are expected to generate in excess of 53,400kWh of energy and contribute significantly to powering the Centre’s electrical equipment.
  • Hager Eco-ficient Presence Detectors will ensure lights in less frequently used areas are only on when needed and will reduce the energy bill for lighting these spaces by 20 per cent.
  • Airblade hand dryers take just 12 seconds to do the job and save up to 80 per cent on the energy used by conventional dryers.  The dryers not only cost less to run but are also more hygienic and produce no waste at all unlike paper towels. For the cost of one paper towel, an Airblade hand dryer can dry up to 19 pairs of hands.
  • Waterless urinals have joined highly efficient flush toilets in the change rooms. The Caroma H2Zero Cube model was been chosen for its 100 per cent water saving capacity.
  • Interpretive signage to explain the workings and benefits of its new sustainable features.

Ms MacTiernan said the City would continue to monitor developments in renewable energy technology, and use renewable energy sources in City-owned facilities where possible and practical.

“The City of Vincent will also investigate and implement the use of alternative lighting technologies, including solar-powered lights and LEDs in parks, reserves, car parks, and right of ways throughout the City. “
