awa news regular features 32 AUGUST 2012 water Water Infrastructure Group Wins Safety Excellence Award AWA and Water Services Association of Australia (WSAA) were joint supporters of the Water Industry Safety Excellence Award at Ozwater in May'12. The award was presented to the Water Infrastructure Group for its Rehabilitation of the Bondi Ocean Outfall Sewer project. The Bondi Ocean Outfall Sewer (BOOS) was the first ocean outfall sewer of its type. Designed and built by the NSW Public Works Department from 1880 to 1889, it was built as an alternative means for disposing of the city's sewage, which until then was being drained into Sydney Harbour. The BOOS is oviform in shape, constructed mainly of bricks, and is considered an engineering masterpiece of its time due to the surveying accuracy. However, after being in continuous service for over 120 years, the inner skin of bricks has deteriorated. It is crucial to keep the BOOS in good operating condition as there is no alternative to collect and transport sewage from Sydney's city, inner west and eastern suburbs to the Bondi Sewage Treatment Plant. Large-scale rehabilitation was required to ensure that the BOOS structure remains intact and that its service life is increased by at least another 50 years. Health and Safety was a priority in undertaking the rehabilitation, with confined spaces and live sewage flows creating a real challenge to maintain and ensure the safety of all members of the work team. To ensure appropriate control measures were put in place, Water Infrastructure Group, in conjunction with Sydney Water, developed a Flow Management Plan that reviewed the risks and established control measures to minimise these risks. Control measures included: • The team's roles and responsibilities each time they enter a sewer; • Ventilation methodology, flow management, emergency response procedures and HIDRA (Hazard Identification and Risk Assessment); • Permits and procedures that need to be completed and complied with for each confined space. A close working relationship between Sydney Water and Water Infrastructure Group ensured that action was taken to identify the root cause of OHS issues, trial solutions and then further develop the solutions in consultation with key stakeholders. The main items that have great potential on other similar projects to prevent injury or to reduce the risk of injury are: • Establishment of D x V levels for working in live sewage flows; • Installation of custom-designed working platforms; • Ensuring continuous communication using two-way radios with aerial cable; • Effective trialling of emergency response procedures; • Use of temporary scaffolding to rehabilitate deep access shafts; • Installation of appropriately designed SS platforms and ladder arrangement to provide future safe access; • Variable ventilation system housed in noise-attenuated working container; • Close community and stakeholder consultation in the changing of traffic conditions to ensure an effective and safe implementation of the temporary measures. Call for Papers -- Ozwater'13 Ozwater is Australia's International Water Conference and Exhibition and is the 'must-attend' event on the water industry calendar. AWA is calling for submissions to present papers, workshops and posters at Ozwater'13 in Perth from 7--9 May 2013. You are invited to submit an extended abstract that presents a challenging perspective on any of the themes that have been identified for this conference. Please visit www.ozwater.org/call-for-papers for further information. Submissions close 30 August 2012. YWP President Awarded IDA Fellowship Mike Dixon, National Committee President of the Young Water Professionals, has won the International Desalination Association's (IDA) Fellowship Award. The 2012 Fellowship is hosted by the Ministry of Electricity and Water (MEW) in Kuwait, with sponsorship from Alghanim International. Consisting of a monetary award and an attachment with the host agency, the Fellowship is considered to be one of the industry's most prestigious awards, recognising individuals with exceptional professional achievements and dedication to advancing desalination and water reuse. As his entry, Mike submitted a project idea to create a Red Tide Algae Operations Manual for MEW to address the threat of red tide blooms in the Arabian Gulf -- and, in particular, in Kuwait where the water is warmest and at highest salinity. Red Tides are common in the Middle East and at times threaten the closure of desalination plants. Because of the Middle East's heavy dependence on desalinated water supplies, this poses serious problems for the region. The project will involve a six-week placement in Kuwait working with MEW in desalination design and construct teams, and working in an operating desalination plant. The Award Ceremony took place at a VIP Luncheon at Singapore International Water Week during the launch of the new IDA Academy. It will mean a significant learning event for Mike and a wider benefit to the industry through the production of a Red Tide Algae Operations Manual.
