House of Assembly Fifty-Fourth Parliament, First Session (54-1) 54 1 Parliament of South Australia House of Assembly published Parliamentary Committees Parliamentary Committees Public Works Committee: Bolivar Dissolved Air Flotation and Filtration Plant Controls Upgrade Project Public Works Committee: Bolivar Dissolved Air Flotation and Filtration Plant Controls Upgrade Project Mr CREGAN House of Assembly Kavel Mr CREGAN (Kavel) (12:04): I move: That the seventh report of the committee, entitled 'Bolivar dissolved air flotation and filtration (DAFF) plant controls upgrade project', be noted. The Bolivar dissolved air flotation and filtration recycled water plant treats approximately 40 per cent of the effluent from the Bolivar Wastewater Treatment Plant. There is an automated control system in place at the plant and a supervisory control and data acquisition system used for remote monitoring and alarming. These systems are essential for the reliable operation of the treatment process. The existing control system is in poor condition and beyond its projected asset life. There have been several upgrades to the plant over recent years. However, parts of the control system are now obsolete. This project will address the age and condition of current equipment, help resolve identified environmental and workplace health and safety issues, ensure the provision of a reliable and flexible system that can accommodate future expansion and allow for process optimisation and efficiencies in operation. The estimated total cost of the project is $6.061 million and it is expected to be completed by April 2022. The Public Works Committee has examined written and oral evidence in relation to the project and the committee has been assured by the department that acquittals have been achieved from the Department of Treasury and Finance and the Crown Solicitor that works and procedures are lawful. The committee is satisfied that the proposal has been subject to the appropriate agency consultation and meets the criteria for the examination of projects as set out in the Parliamentary Committees Act 1991. Based on the evidence considered and pursuant to section 12C of the Parliamentary Committees Act 1991, the Public Works Committee reports to parliament that it recommends the proposed public works. Motion carried.
