34 awa News water APRIL 2015 AWA HOSTS THAI DELEGATION TO AUSTRALIA Austrade and AWA are fostering closer economic cooperation and knowledge sharing between the Thai and Australian water sectors, writes Paul Smith, AWA’s Export and Market Access Manager. Bangkok is one of the world’s major metropolitan areas that have undergone rapid urbanisation and industrialisation. With an area of 1570km2 and situated approximately two metres above sea level, it has a population of about 10 million and faces many challenges in the delivery of safe, secure and sustainable water and wastewater services. Due to uncontrolled discharges of agricultural, domestic and industrial wastewaters into the Chao Phraya River and Mae Klong River, river water quality is deteriorating. The effects of global warming have also caused river flows to be unreliable, with increased flood recurrence during the wet season and harsher drought periods during the dry season. According to the Bangkok Municipal Authority, heavy pumping of groundwater has resulted in land subsidence of two to 15cm/year, as well as groundwater contamination. With the ongoing growth of Bangkok, problems of water resource management and contamination of both surface and groundwaters are likely to worsen. Bangkok munIcIpalIty authorIty mIssIon to sydney In support of Thailand’s ambitions to improve the management of water and wastewater, in February 2015 AWA and Austrade hosted a delegation from the Bangkok Municipality Authority (BMA) to tour water management sites in Sydney and meet with water professionals and water businesses. The BMA tour included: • Central Park Water Recycling Facility, hosted by Flow Systems and Professor Stuart White from the Institute for Sustainable Futures (ISF); • North Head Sewerage Treatment Facility and water recycling scheme run by Sydney Water; • Manly Beach, for an overview of Manly Council’s Water Cycle Management Program and stormwater re-use schemes; • A residential development in Palm Beach using innovative vacuum sewerage collection systems, provided by FloVac; • NSW Public Works Manly Hydraulics Laboratory (MHL) facilities to see how the NSW Government monitors and responds to flood management and learn about the NSW Coastal and Flood Data Collection Program, managed on behalf of the NSW Office of Environment and Heritage (OEH) (www.mhl.nsw.gov.au); • Business matching at a BBQ lunch at Manly Dam; • A boat tour of Sydney Harbour (courtesy of Ecosol). The delegation also heard expert insights on each site from the NSW Department of Health, NSW Public Works’ Manly Hydraulics Laboratory, NSW Office of Water, Sydney local councils and ISF. The final day of the tour included a BBQ lunch and business matching on the banks of Manly Dam. The BBQ allowed AWA members to set up demonstration models of products and display capabilities. It included the following companies: • STAR Water Solutions: www.starwater.com.au • Neuplex: www.neuplex.com • Biogill: www.biogill.com international A street scene during the Bangkok flood in 2014.
