    SEQWATER’S 22 OCTOBER SUBMISSION / RESPONSE TO QCA REQUEST OF 12 OCTOBER 12 October 2012 I hereby provide Seqwater with a further information request. 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.

  • Purified Recycled Water in the Lockyer Valley
    Fact Sheet December 2012 Purified Recycled Water in the Lockyer Valley The water supply security of South East Queensland (SEQ) has recently been increased by the construction of the Western Corridor Recycled Water Scheme. The infrastructure of advanced wastewater treatment plants provides purified recycled water (PRW) to the SEQ Water Grid for indirect potable reuse of effluent from urban areas. With a maximum combined production capacity of 232 million litres of PRW a day, it is the third largest recycled water scheme in the world and the largest in the southern hemisphere. This additional water supply is critical during drought conditions but is underused in wet periods. The provision of recycled water in an environmentally Background sound and socially-equitable manner requires measured The Urban Water Security Research Alliance (the Alliance) understanding of the potential impacts on the region’s worked closely with the Queensland Water Commission, soils, groundwater system, environment (such as salinity the former Queensland Department of Environment and issues) and the economy. Therefore, a holistic framework Resource Management, WaterSecure (now Seqwater) and was required to inform an integrated water management the SEQ Water Grid Manager, as well as irrigators and the plan involving the use of PRW. This was achieved through farming community. a multi-tiered assessment incorporating environmental risk analysis, climate modelling, regulatory considerations and Together we explored the feasibility of providing agro-economics. approximately 20 million litres per year of PRW to supplement irrigation supplies in the Lockyer Valley, 80 km The environmental risks and benefits from the supply of PRW west of Brisbane. were the core subjects addressed by this research, using a combination of field research, water quality and quantity Alliance research explored whether the use of PRW can serve modelling , and unstructured stakeholder interviews.

ISBN-13:978-0-9943790-1-6 © Seqwater 2015 This publication is correct at time of writing and is subject to change. B Water for life Water gives and sustains life. It supports healthy communities and a prosperous South East Queensland (SEQ). It is an essential service that is delivered to 3.1 million people across our region every day. As the region’s bulk water supply authority, we are committed to water for life. We are charged with delivering safe, secure and cost-effective water and catchment services to our customers and communities today and in the future. In SEQ we live in a climate of extremes – from times of drought to floods – and we need to be ready to adjust our water use and management when conditions change. Our research tells us that apart from a severe drought or a sharp increase in demand, we have enough water to supply our region for about 15 years. But after that, we will need new water sources to meet growing demand.
