Introduction 1.1 Project Background Seqwater is undertaking the South West Pipeline and Wyaralong Tanks Project works to future proof the Beaudesert Water Supply Zone (WSZ) for a 30-year horizon. The township of Beaudesert is currently supplied with bulk water from the Beaudesert water treatment plant, which draws raw water from the Logan River. Ammonia events and high turbidity during wet weather events have previously required the plant to temporarily cease production. The Beaudesert Township water demand is too large to service via water tankers during loss of supply and it is not connected to the South East Queensland Water Grid and will not meet levels of service into the future. Growth in the area, including from the Bromelton State Development Area (SDA) and Gleneagle is projected to exceed supply in the coming years. Nearby developments in the South Logan area, in particular the Yarrabilba and Flagstone Priority Development Areas (PDAs) are also increasing demand which is currently supplied by the Southern Regional Water Pipeline (SRWP). To improve the reliability of water supply within the Beaudesert Water Supply Zone, Seqwater is proposing the development of the South West Pipeline (approximately 27 km) running from the existing Beaudesert WTP site northwards to the new Wyaralong tanks located on the northern banks of the Logan River at Bushland Road, Riverbend. To complete the project and secure a water supply connection into the South East Queensland Water Grid, Seqwater is proposing to develop the Flagstone connection pipeline (approximately 3.5 km), running north from the Wyaralong tanks to the existing Logan City Council (LCC) Network near the intersection of Teviot Road and Glynton Road, Flagstone. A secondary project will involve the construction and operation of a new water treatment plant (Wyaralong WTP) at the Wyaralong Tanks site. This project will be constructed six to eight years after the first project. For the purposes of this SIMP the impacts of the two projects are considered separately and only the South West Pipeline Project is assessed. 1.2 Project description The Beaudesert South West Pipeline and Wyaralong Tanks Project (the Project) is comprised of three elements including the proposed Beaudesert South West pipeline route, Flagstone connection pipeline (the pipeline) and Wyaralong tanks (Figure 1). The Project connects the existing water supply network at Flagstone near South Maclean, to Beaudesert, traversing Riverbend within the Logan City Council Local Government Area (LGA) and Cedar Grove, Kagaru, Allenview, Woodhill, Gleneagle and Bromelton within Scenic Rim Regional Council LGA. The Flagstone connection pipeline will be approximately 3.2 km and is intended to connect the Wyaralong Tanks to the existing infrastructure supplying the Logan City Council area and the Flagstone developments. This connection pipeline follows Bushland Road (currently not constructed) within road reserve in LCC. Bushland Road is required to facilitate construction of the tanks and to allow access to this property. The road is required to access the Wyaralong tanks construction. Bushland road has to be vertically re-aligned to meet Q200 access requirements (cut and fill) and also to meet the correct high code gradients. The Bushland Road section of pipe needs to be laid at the correct levels in the newly formed road. Other stakeholders also propose to locate GHD | Report for Seqwater - South West Pipeline and Wyaralong Tanks Project, 4131901 | 1 services in the road including underground power (Energex , and wastewater (Logan Water Infrastructure Alliance). The Wyaralong tanks element includes a transfer pumping station, 2x18 ML transfer storage tanks (approximately 55 m in diameter), vehicle manoeuvring, on-site storage and plant. The South West Pipeline crosses Logan River at the Cedar Grove Weir and travels south for 23 km along road reserve through rural-residential areas until 130 Bromelton House Road whereby it will be required to cross through private land to reach gazetted roads on the east side of the Logan River which it follows to the Beaudesert WTP. 1.3 Purpose of this report This report has been prepared based on the proposed South West Pipeline
