  • These 3 units have been clustered together as they have common skills and knowledge requirements. They also follow a logical process for operational management activities. NWP403A relates to the coordination, monitoring and optimisation of system performance and maintenance planning in potable water distribution systems. It is suitable for staff with a specific responsibility for ensuring that potable water systems comply with organisational and statutory requirements.NWP532B is related to activities associated with the implementation and management of potable water distribution systems, including system performance analysis, customer liaison and planning. It is suitable for managers in water organisations with responsibility for the implementation of potable water system management plans, and those that assist in this process. NWP533B provides the skill to develop and review a potable water distribution system management plan, including system performance analysis, customer liaison and planning and maintenance. It is suitable for managers in water organisations with responsibility for the management of the potable water management system, and those that assist in this process.
  • This project uses the planning tool from using http://communitywaterplanner.gov.au and information as provided by your trainer and researched in your workplace. This assessment should be completed over the period of this enrolment with deadlines for each Task given by your trainer.
  • Welcome to Week 1 where we will discuss how to Implement and Manage a Potable Water System Management Plan.In QLD the Water Supply (Safety and Reliability) Act 2008 has been in place since mid 2008 and its provisions regulate drinking water quality to protect public health. The legislation applies to drinking water service providers (service providers) registered with the Department of Energy and Water Supply (the regulator), particularly those involved in treating, transmitting or reticulating water for drinking purposes.The primary method by which the regulator ensures that public health is protected is by approving a service provider's Drinking Water Quality Management Plan (DWQMP), and ensuring that the service provider complies with the plan.The DWQMP also supports the Department of Sustainability, Environment, Water, Population and Communities' National Water Quality Management Strategy (NWQMS), which is a joint national approach to improving water quality in Australian and New Zealand waterways. It was originally endorsed by two Ministerial Councils - the former Agriculture and Resources Management Council of Australia and New Zealand (ARMCANZ) and the former Australian and New Zealand Environment and Conservation Council (ANZECC). The NWQM includes 7 documents for water quality guidelines set out as ‘water quality benchmarks’, ‘ groundwater management’, ‘diffuse and point sources’. ‘guidelines for sewerage systems’, ‘effluent management’ and ‘water recycling’.The DWQMPs are designed to reflect the best practice process outlined in the Australian Drinking Water Guidelines (ADWG) as a risk based approach to transparently managing the quality of potable water suppliers main product.
  • Document any legislation, regulation, Acts or policies you are familiar with relating to drinking water quality.
  • A Drinking Water Quality Management Plan is developed in line with the document “Guidelines for creating a Drinking Water Quality Management Plan” from DERM, September 2010. This Plan must be submitted to DERM for approval and then reports submitted annually measuring routine analyses of water quality against the target performance measures set in line with the Australian Drinking Water Guidelines. By aligning with the Australian Drinking Water Guidelines a Drinking Water Quality Management Plan provides a systematic, measurable and reportable framework that both Service Providers and Regulators can utilise to ensure a safe and food-grade product is consistently delivered to customersResource: Guidelines for creating a Drinking Water Quality Management Plan; available from http://www.nrm.qld.gov.au/water/regulation/drinking/index.html
  • The Australian Drinking Water Guidelines provide levels and limits for many physical, chemical and biological parameters likely to be found in drinking water. These levels and limits provide a precise guide for the safety and aesthetic qualities of drinking water. World Health Organisation estimates each year approximately 2.4 million deaths are caused by unsafe water and lack of sanitation.
  • A Drinking Water Quality Management Plan provides a structured method of minimising risk to consumers. This includes proactively maintaining assets in good condition which will consistently deliver good quality water to consumers.Discussion prompt: how are asset maintenance plans implemented in your workplace? How would a poor maintenance plan affect drinking water quality?
  • Data from numerous sources can be utilised for monitoring and reporting of water quality. This data can be used to support changes over time (eg population growth vs water usage) and also to help explain anomalies or non-conformances in water quality (eg heavy rains can lead to dirty water problems, flooding of plants, etc) The best and most basic way to compare water quality statistics is to assemble as much historical data as possible into a data base. Then the provider can take current data from sources such as analyses of water samples, water usage, costs/budgets, asset performance figures (broken mains, etc) and compare with historical data. This will then generate trends for future planning and asset management. By comparing current data with historical data a Water Service Provider can generate trends which is helpful in future planning and asset management.
  • By using all of this data and these trends and comparing with the set targets or benchmarks in the Drinking Water Quality Management Plan and the Australian Drinking Water Guidelines, a service provider will be in a position to optimise the delivery system and ensure continuing reliable delivery of good quality water.
  • Document existing distribution system performance data used in monitoring and reporting water quality. How might the distribution system have affected these results? Consider sampling point locations; leakages; flood impact; pipe condition etc..Consider and discuss point source and non-point or diffuse source pollution.
  • The modification of natural stream flows by dams and weirs can also affect water quality. The weather, too, can have a major impact on water quality, particularly in a dry country like Australia which is periodically affected by droughts.Generally the water quality of rivers is best in the headwaters, where rainfall is often abundant. Water quality frequently declines as rivers flow through regions where land and water use are intense and pollution from intensive agriculture, large towns, industry and recreation areas increases.Of course, there are exceptions to the rule and water quality may improve downstream, behind dams and weirs, at points where tributaries or better quality groundwater enter the main stream, and in wetlands.Rivers frequently act as conduits for pollutants by collecting and carrying wastewater from catchments and, ultimately, discharging it into the ocean. Stormwater, which can also carry heavy loads of nutrients, organic matter and pollutants, finds its way into rivers and oceans, mostly via the stormwater drain network. Beach water quality in NSW may also be affected by bacteria from sewer overflows or other runoff into stormwater drains
  • Document existing geology and land use data used in monitoring and reporting water quality. Consider and discuss catchments, source water and seasonal flows impacts.
