Seqwater’s detailed responses to each item would be appreciated by COB 19 October 2012, please. Happy to discuss at any time noting the proposed due date of COB 19 October 2012 From: Colin Nicolson [mailto:[email protected]] Sent: Friday, 19 October 2012 1:10 PM To: Angus MacDonald Cc: George Passmore; Damian Scholz Subject: FW: Information Request 12 October 2012 Hello Angus Here are our responses to the above information request. QCA Question 1 - Cedar Pocket Stakeholders (Issues Arising (IA) Cedar Pocket 2012) submitted that more details were required regarding Seqwater’s proposed renewals expenditure [outlined in the NSP] on “electricity supply assets” in 2025-26 at $30,000. Please provide more details regarding this proposed expenditure. Seqwater Response to Item 1 The Assets in question are a property pole, meter box (excluding the meters), cabling and a distribution board. The renewal is scheduled based on the Seqwater “standard asset life” of 20 years for this type of equipment. It was installed in 2005 and will be 20 years old when the work is scheduled. The cost estimate is drawn from the estimated replacement costs as set out in Section 5.2.2 and Section 9 of the Irrigation Infrastructure Renewal Projections - 2013/14 to 2046/47 Report on Methodology. The renewal timing, will be reviewed on an ongoing basis so that it is only delivered when condition warrants. The scope and cost estimate will be reviewed prior to commencement of work to ensure the delivery is efficient. -

The horizontal version is the preferred format, however due to design, space and layout restrictions, the vertical version can be used. Our logo needs to be produced from electronic files and should never be altered, redrawn or modified in any way. Clear space guidelines are to be followed at all times. In all cases, our logo needs to appear clearly and consistently. Minimum size 2.1.2 Primary logo minimum size Minimum size specifications ensure the Urban Utilities logo is reproduced effectively at a small size. The minimum size for the logo in a horizontal format is 50mm.

Fact Sheet Wivenhoe Dam
Fact sheet Wivenhoe Dam Wivenhoe Dam Wivenhoe Dam’s primary function is to provide a safe drinking Key facts water supply to the people of Brisbane and surrounding areas. It also provides flood mitigation. Name Wivenhoe Dam (Lake Wivenhoe) Watercourse Brisbane River The water from Lake Wivenhoe, the reservoir formed by the dam, is stored before being treated to produce drinking water Location Upstream of Fernvale and follows the water journey of source, store and supply. Catchment area 7020.0 square kilometres Length of dam wall 2300.0 metres Source Year completed 1984 Wivenhoe Dam is located on the Brisbane River in the Somerset Type of construction Zoned earth and rock fill Regional Council area. embankment Spillway gates 5 Water supply Full supply capacity 1,165,238 megalitres Wivenhoe Dam provides a safe drinking water supply for Flood mitigation 1,967,000 megalitres Brisbane, Ipswich, Logan, Gold Coast, Beaudesert, Esk, Gatton, Laidley, Kilcoy, Nanango and surrounding areas. The construction of the dam involved the placement of around 4 million cubic metres of earth and rock fill, and around 140,000 Wivenhoe Dam was designed and built as a multifunctional cubic metres of concrete in the spillway section. Excavation facility. The dam was built upstream of the Brisbane River, of 2 million cubic metres of earth and rock was necessary to 80 kilometres from Brisbane City. At full supply level, the dam construct the spillway. holds approximately 2,000 times the daily water consumption needed for Brisbane. The Brisbane Valley Highway was relocated to pass over the dam wall, while 65 kilometres of roads and a number of new Wivenhoe Dam, along with the Somerset, Hinze and North Pine bridges were required following construction of the dam. -
Somerset and Wivenhoe Dam Safety Upgrades – Business
Somerset and Wivenhoe Dam Safety Upgrades – Business Case Stage APRIL 2019 Somerset Dam was built between 1937 and 1959. Wivenhoe Dam was completed in 1985. Both dams were designed to the engineering standards of their time. We now know more about the risks of extreme floods to the Somerset and Wivenhoe Dam walls. Both dams will be upgraded so that they can withstand much larger floods. What has changed since the dams were built? Some things have changed since the dams were built or last upgraded. These include: • significant population growth downstream • advances in dam design and the development of consistent risk assessment methods • improved estimates of extreme rainfall events • data from recent floods and updated flood modelling. An independent assessment has found the dams do not meet modern Queensland Government dam safety guidelines. We now know extreme floods could exceed the design capacity of the dams. Under the Water Supply (Safety and Reliability) Act 2008, we need to upgrade both dams to meet the guidelines. Lowering water levels in Somerset and Wivenhoe In January 2016, Seqwater changed the way it manages both Somerset and Wivenhoe Dams. These changes immediately improved the ability of both dams to withstand extreme floods and maintain flood mitigation. Changes include: • Changing the flood operations manual for both dams • Lowering the water supply storage volume of Somerset Dam to 80% of its normal volume • Lowering the water supply storage volume of Wivenhoe Dam to 90% of its normal volume. Lowering the water supply storage volume increased the flood storage volume in the dams. What to expect Get involved The water supply storage levels in both dams will remain Identifying the social, environmental and heritage impacts lowered during the design and construction of the of the shortlisted upgrade options for Somerset Dam is part Somerset Dam safety upgrade. -
