Frequently Asked Questions General Why is Rous County Council updating the region’s Future Water Strategy? Rous County Council has a responsibility to ensure our community has a safe and secure drinking water supply now and into the future. We are now developing a delivery program to secure our region’s water supply through to 2060. Like many areas in Australia, we are planning and preparing for our long-term water security. In planning for the future, we need to weigh up all impacts including environment, social and economic. The 2014 Future Water Strategy recommended further investigations into groundwater as a possible future water source. Unfortunately, these investigations indicate that this will not be a feasible option for all our future water supply needs. This is based on several factors including water quality, reliability and costs to extract. The unsuitability of groundwater as a viable water source has meant we need to go back and develop other options. We are now undertaking these additional investigations to update the Future Water Strategy and finalise our delivery program. How is Rous County Council developing the delivery program? The NSW Department of Planning, Industry and Environment (DPIE) has provided guidelines on how to develop an Integrated Water Cycle Management (IWCM) Strategy. We are using these guidelines to build on the 2014 Future Water Strategy. Since 2014, Rous County Council has been undertaking extensive investigations around options including demand management, groundwater, desalination, potable water recycling and dams. The outcomes of these investigations are now being assessed to ensure that the ultimate delivery plan balances the needs of water security, operational and capital costs, environmental impact and social impacts. When is the delivery program expected to be finalised? Rous County Council is anticipating that the draft delivery program will be presented to Council in June 2020. Once adopted, it will be available for public consultation. Refer to the ‘How can I have a say in our future water supply’ question in the ‘Other’ section below for more information on the proposed consultation process. How do you know that our current sources of water will not cater for new developments? The Future Water Strategy was adopted in 2014. The Strategy concluded that the Rous County Council regional bulk water sources can meet demand for the short to medium term, however to maintain a sustainable water supply for the region, the Future Water Strategy recommended key actions be undertaken to guide long-term water planning and provide certainty about water needs and infrastructure development over future decades. Over the next 50 years, changes to climate and rainfall patterns are expected to reduce the reliability of rainfall for the region. At the same time, water use is forecast to increase as the population grows. Future Water Strategy | Frequently Asked Questions | Page 1 of 6 By around 2024, we expect that demand for water will match what current sources can reliably supply. However by 2060, it is expected that demand will exceed reliable supply by 6,500 megalitres per year, or approximately half of the current secure supply. A copy of the demand forecast is available here. To meet the shortfall, the initial Future Water Strategy recommended a combination of improved water conservation and the investigations into new groundwater sources over the next 10 years. More information on the methodology on how local water utilities need to determine water security requirements can be found here: Assuring future urban water security. How have you considered the effects of climate change? The effects of climate change are being considered in our planning. The methodology for assuring future urban water security has a specific process to account for the effects of climate change. Over the next 50 years, changes to climate and rainfall patterns are expected to reduce the reliability of rainfall for the region. At the same time, water use is forecast to increase as the population grows. Rocky Creek Dam and Emigrant Creek Dam are usually relatively full. Why do we need a new source of water? Over the next 50 years, changes to climate and rainfall patterns are expected to reduce the reliability of rainfall for the region. At the same time, water use is forecast to increase as population grows. We have already seen the need to implement water restrictions as recently as the end of 2019. By around 2024, we expect that demand for water will match what current sources, including Rocky Creek and Emigrant Creek dams. A copy of the demand forecast is available here. To meet the shortfall, the initial Future Water Strategy recommended a combination of improved water conservation and new water sources. What is it all going to cost and how will that effect my water bill? A key part of our investigations into future water sources includes the financial implications of each option. In planning for the future, we need to weigh up all impacts including environment, social and economic. The ultimate effect on your water bill will be determined by your local council in consultation with Rous County Council. How does Rous County Council charge the council for the bulk water it supplies to the local councils, and how does this compare to other nearby regions? Council's fees and charges provide a list of the chargeable services, requests and applications provided by Rous County Council, and are updated on an annual basis. For more information, please refer to the Rous County Council 2019/20 Fees and Charges and Revenue policy. How does my local council determine the cost per kilolitre charge for water on my rates bill? Local councils provide details on all their respective fees and charges within their annual reporting documents. Typically, the basis for determining these fees and charges is derived from a policy of the council. Usually, water and sewerage charges are based on a full cost recovery arrangement.

Following the completion of the initial Future Water Strategy in 2014, Rous County Council has undertaken extensive investigations into the use of groundwater for our future water supply. Unfortunately, these investigations indicate that ground water by itself will not be a feasible option for future water supply. This is based on several factors including water quality, reliability and costs to extract. Apart from dams, what other potential water sources are there in the region? In addition to dams, we have been investigating solutions around groundwater, water reuse, desalination and integration into other water supply systems within the region. Will the use of groundwater for town water supply impact on agriculture and surface water, such as streams and rivers? At this stage, use of groundwater for town water supply is not considered a viable option to meet all the region’s needs. This is due to water quality, reliability and costs. If groundwater does form part of the region's future water sources, then we will undertake robust local hydrogeological assessments of aquifers and any potential connectivity with Groundwater Dependant Ecosystems (GDEs) and surface water streams and rivers. This is typically undertaken via pumping tests of groundwater bores and monitoring programs of other nearby bores and streams and rivers. Is indirect potable water reuse still being considered? Indirect potable reuse is the reclamation and treatment of water from wastewater and is one of a number of possible options. While it will remain an option, at this stage it is a low priority, as both costs and regulatory approvals means that it is not appropriate to implement in the short or medium term. What other sources of water have been considered? Is connecting to the Toonumbar Dam an option instead of new groundwater bores, desalination, or a new dam? Any connection to Toonumbar Dam, north-west of Kyogle, would require significant changes to the way in which this dam is regulated and managed. Additionally, it is understood that based on the dam’s current configuration, there is insufficient existing secure water allocations available to make this a feasible option for future water supply. Why can't Rous County Council just build a new dam now? Building a new dam is not a decision to be taken lightly so we want to ensure we effectively explore and understand the social, environmental and economic factors. If a decision is made to build a dam, planning, design, approvals and construction may take up to nine years to complete. Is Dunoon Dam still planned? Dunoon Dam is one of a number of options under consideration. Are any other dam sites being considered? If so, where? At this stage, no additional new dam sites are being considered. Demand and water conservation How does water conservation fit in with the Future Water Strategy? Water is a precious resource. Managing our demand is the most practical and cost-effective step in ensuring we have a future water supply. However current indications are that this will not be enough on its own. Water conservation and demand management is a long-term program and will be part of the solution, regardless of the option eventually chosen. Future Water Strategy | Frequently Asked Questions | Page 3 of 6 How much water does the region use annually? Current water demand across the region is 12,130ML per year (bulk water production by Rous County Council). This is equivalent to almost 5,000 Olympic swimming pools (per year). Why can’t we restrict the wasteful use of water – washing footpaths and driveways for example? We all have a role in saving water and using this resource wisely, even in times of no water restrictions.
