1 Sydney Water Operating Licence Environment Report Environment Plan Annual Report Environmental Indicators Report

2 Introduction Sydney Water is governed by the Sydney Water Act 1994 (the Act) and conducts its activities under an operating licence granted by the NSW Government. Sydney Water's Operating Licence commenced on 1 July This includes Sydney Water s performance for the Environment Plan and the Environmental Indicators Report. Sydney Water is required to provide these reports to the Independent Pricing and Regulatory Tribunal (IPART) by 1 October annually. The report is also available for public access on Sydney Water's website Environment Plan Annual Report Sydney Water s Environment Plan is the cornerstone of the Sydney Water Environmental Management System. The Environment Plan sets environmental objectives and targets for the organisation and is mapped to the corporate goals or objectives. Progress is tracked quarterly through Sydney Water s business plans and reported annually to the Independent Pricing and Regulatory Tribunal (IPART). Environmental Indicators Report The Act and the operating licence require Sydney Water to compile indicators of the direct impact of its activities on the environment to enable preparation of an annual report on its performance and to provide year to year comparison in relation to its performance. IPART determines the environmental indicators to be reported and publishes these in the Operating Licence Reporting Manual (available on IPART s website Thirteen (13) National Water Initiative (NWI) and 33 IPART environmental indicators are contained in the reporting manual in tables E.5 and E.6. Sydney Water must report its performance against these indicators annually for the financial year 1 July to 30 June to IPART. The NWI indicators are part of the National Performance Framework that were developed by the Water Services Association of Australia, the National Water Commission, the Bureau of Meteorology and NWI partners. The NWI is a shared commitment by governments to improve the management of Australia s water resources, including using water resources efficiently. Data from Australian water utilities is collated annually and published in a National Performance Report. The report provides a national and comparative report card on water utilities that enables consumers and governments to assess how well their providers are performing. The IPART indicators in this report are additional indicators compiled by IPART that are specific to Sydney Water. SWEMS v5 Page 2 of 36

Areas to improve Positive trends for some indicators and negative trends for others towards the target. Relatively low impact from delay Action required Data shows a negative long-term trend in relevant indicators towards the target. High impact from delay Objective Target Action Due Status Progress Summary Corporate goal: Serving customers Service delivery requirements are aligned with customer expectations Manage noise from construction, operation and maintenance of assets to achieve a downward trend in complaints Odour programs are in place for high risk treatment plants and networks to achieve a downward trend for odour issues Maintain downward trend in annual number of odour complaints from wastewater treatment plants and the reticulation system based on the preceding four-year average Comply with Noise Management Code of Behaviour Implement Noise Awareness Training for staff Monitor noise complaints Implement odour control programs Plan and apply decision framework for other high risk Wastewater Treatment Plants (WWTP) Monitor odour complaints and develop remedial strategies as appropriate As per program There was full compliance with the Noise Management Code of Behaviour in This is an improvement from which had one noncompliance, and three in Noise awareness training was delivered to all maintenance staff in May Noise awareness refresher briefings are scheduled for late Annually There were 64 noise complaints attributed to Sydney Water or its contractors in This equates to 0.04 complaints per 1000 properties. This was down from 83 noise complaints recorded in which equates to 0.05 complaints per 1000 properties. Ongoing Sydney Water worked with the Department of Planning and Infrastructure to develop a NSW Best Practice Odour Guideline. The Guideline replaces the current 400 metre buffer area around all wastewater treatment plants with compatible land uses. Sydney Water is addressing potential land use conflicts by negotiating suitable land uses within 400 metres of treatment plants with planning authorities. Work on upgrading scrubbers at the Malabar Wastewater Treatment Plant (WWTP) and Cronulla WWTP is continuing and is on track to meet the project completion date of March At the completion of these projects, odour emission will satisfy the Office of Environment and Heritage (OEH) guidelines. Dec-12 The decision framework for other high risk Wastewater Plants was developed and applied for Warriewood; North Head and Wollongong Wastewater Treatment Plants. Plans are in place to proceed if odour risks materialise at Wollongong and St Marys Recycled Water Plants. Plans will be developed for Liverpool, Shellharbour and Penrith Wastewater Plants for implementation should odour risks materialise. Annually There were 330 odour complaints associated with wastewater treatment and network processes for This is below the preceding four year average of 378. SWEMS v5 Page 4 of 36

5 Status Exceeded or met Evidence shows a positive long-term trend towards the target or target is met. Areas to improve Positive trends for some indicators and negative trends for others towards the target. Relatively low impact from delay Action required Data shows a negative long-term trend in relevant indicators towards the target. High impact from delay Objective Target Action Due Status Progress Summary Corporate Goal: Maintaining a water efficient city Water efficiency and conservation measures are used to plan for the provision of future services Support current and future water efficiency programs to maintain Operating Licence target of less than 329 litres per person per day Support delivery of existing water efficiency initiatives and programs through research and development and communication of water conservation programs Develop a new forecasting model and monitor trends in water demand and savings Implement new technologies where they have been proven to be effective and cost efficient Ongoing In , water use was 297 litres per person per day, compared to 304 litres in This lower demand reflects a decline in the use of drinking water by some non-residential customers. For example, the partial closure of BlueScope Steel at Port Kembla and the start of the new recycled water scheme at Rosehill led to a reduction in drinking water use at these sites. It also reflects the ongoing efforts by customers to maintain water saving behaviours that were established while drought restrictions were in place A new short term demand forecasting model was completed in This model was included in Sydney Water's submission to the 2011 IPART Pricing Determination. In Sydney Water continued to monitor water use trends. A number of research and analysis projects were undertaken, including: preliminary analysis on the apparent shift in residential water use that has occurred since the last drought began in the late 1990s. finish collecting data describing the types of water using fittings and appliances in customers homes (further analysis of this data will continue in ) analysis to develop and deliver a number of new water efficiency programs, including PlumbAssist which aims to provide customers in financial hardship with access to essential plumbing services and reduce water wastage. Ongoing Sydney Water's Water Conservation Strategy was completed in This strategy includes water efficiency, leak reduction and recycling programs targeting the residential, business and industrial sectors. The focus of this Strategy was to deliver water conservation projects where they were cost-effective to do so. Due to the continuing low water use and the maturity of Sydney Water s broad-scale subsidised water efficiency programs, Sydney Water s approach to water efficiency has changed. In Sydney Water s water efficiency focus shifted to deliver services that customers value while limiting increases to water bills. New water efficiency services were developed and tailored to individual customer circumstances which have resulted in cost effective delivery. For more performance information against this target see the Water Efficiency Report on Sydney Water s Annual Report website. SWEMS v5 Page 5 of 36

Jun-12 Water main renewals program was completed and targets were achieved. The decision support tools for critical watermain renewals are proving effective. Sydney Water is working with other water authorities to further improve decision support tools. Jun-12 In , Sydney Water inspected 12,045km of watermains for leaks. The annual target to inspect and repair leaks for 12,000km of watermains was achieved. Dec-11 Sydney Water submitted its review of the Economic Level of Leakage to IPART in December Average water leakage was calculated as 115 ML/day for This figure is within the acceptable range of 105 ± 16 ML/day. Jun-12 The ongoing Leakage Management Program has four elements: pressure management; response to leaks; flow meters; and active leak management. This program is currently being implemented and is meeting the target of maintaining leaks at or below the economic level of leakage. The development of a revised plan for Leakage Management will further investigate cost effective strategies for pressure management. Jun-12 In , Sydney Water constructed 179 Pressure Management Schemes to reduce water leaks from pressure associated issues in high pressure areas. To date, these schemes are saving close to 22 ML/day. The flow meter program is on target, completing 242 installations to date.
