The pipeline from Wivenhoe Dam provides security of supply when combined dam levels fall below 40 per cent. Management of our catchments and water sources is important and this year saw investigations into catchment management and underwater (bathymetry) investigation of storages. The safety of our dams is a top priority of Council and this year again saw the completion of annual safety inspections to identify areas of risk and action plans to mitigate these potential issues. These analyses assisted with review Emergency Action Plans for each of our dams to meet new regulatory requirements. Works to the Western Trunk Main at Hogg Street on Tor Street were completed this year with upgrades to the 675 millimetre trunk water main. These works have ensured that Council can continue to provide a sustainable water supply to West Toowoomba. The township of Wyreema has been connected to the Toowoomba Bulk Supply to meet growth in the area. The work included the construction of a 7 kilometre pipeline connecting to the main Toowoomba water supply at Westbrook. The design of a 7.6 kilometre trunk water main was also completed this year to improve reliability of supply to the growing Toowoomba Enterprise Hub at Charlton. The proposed trunk main will connect to the Toowoomba Network at the corner of Hursley Road and Greenwattle Street and will continue along Hursley Road, Cecil Plains Road and O’Mara Road linking into the existing network at O’Mara Road. The trunk main will consist of 375 millimetre and 450 millimetre diameter pipelines. Tenders were called this financial year for completion of the works for the 2016-17 financial year. Quality drinking water for our region Council successfully delivered a high compliance with the Australian Drinking Water Guidelines and Drinking Water Quality Management Plans in the operation of the Toowoomba Region water supply system. The operation of Council’s Mount Kynoch Water Treatment Plant in compliance with Department of Environment and Heritage Protection licence conditions is a key focus of Council. This included improving backup systems, fully-functioning alarm systems and compliance. This year also saw the completion of Water Supply studies in both Blue Mountain Heights and Yarraman. Following a re-certification audit carried out in April 2016, Council maintained Third Party Certification for ISO 9001:2008. This certification will expire at the end of 2018 when recertification to the new ISO:2015 standard will be required. Works to investigate, design, construct and commission approved Clifton water supply treatment infrastructure improvements were completed this year. The trials of the Pilot Water Treatment Plan for Clifton were successful, with reporting completed this financial year. The further progression of this project will depend on stakeholder consultation and further approvals. TOOWOOMBA REGIONAL COUNCIL Annual Report 2015 - 2016 Our goals CHAPTER 4 105
