The towns are separated by the Kiewa River and its floodplain, with 153 persons residing in Kiewa and 354 in Tangambalanga. Recent growth in the towns has pushed the population to a threshold where demands on I services such as sewage treatment and disposal, and water supply require their implementation and/or upgrading. This Structure Plan and Services Review provides a framework within which the towns can grow to meet the current and future demands of Kiewa/Tangambalanga's population for the next ten years. The Structure Plan has I been prepared by the Albury-Wodonga Region Planning Advisory Committee (AWRPAC) in conjunction with the Shire of Yackandandah, with specialist input from I Gutteridge, Haskins and Davey Pty. Ltd. on services. 1. The Structure Plan for Kiewa/Tangambalanga indicates the preferred pattern of development for Kiewa/Tangambalanga for the next ten years, with further I options for growth beyond the year 2002. The key aspects of the Structure Plan are: • Residential infill and consolidation in Kiewa/Tangambalanga should be I encouraged, noting that a policy of infill should become a more attractive option when a reticulated sewerage system is in place. I • Provision for new residential growth areas in Tangambalanga should occur within an orderly pattern given the location of the existing development fronts and the flexibility for above average population . I growth rates to be contained within such fronts. • Ample rural residential land is available for the life of the plan, noting that a choice of fronts for rural residential in Tangambalanga should be I identified in the medium term. • Adequate protection of the Kiewa River and its floodplain from I undesirable environmental impacts associated with residential and other development will peed continual monitoring. 2. The review of services for Kiewa/Tangambalanga has been based on the key I objective of progressing the development of a strategy to fulfil the servicing requirements of Kiewa/Tangambalanga over the next ten years, including recommending services that can be provided in a cost effective manner for the I community and responsible authorities alike. The key aspects emerging from the review of services are: I SEWAGE • The preferred option for sewage treatment is a lagoon system through which the wastewater passes. Capital cost is estimated at $340,000 with I an annual operating cost of $35,000. Land acquisition costs would be additional. I • The preferred option for disposal of sewage effluent is an irrigated tree lot at a capital cost of approximately $210,000. Land costs for leasing or I purchase would be additional. I I ·f ::.,.: ,~'.'. i : 2 I • Lagoon treatm.ent and tr~~ irrigation for sewage is the most effective and preferred optIOn for Klewa/Tangambalanga from both a cost and I environmental perspective. J:. majg~ advantage of thjs option is that the water courses such as the K.Iewa Kiver are fibt having treated effluent directly discharged into them and irrigated tree lots are able to be harvested and used in wood processing operations. I • An approximate cost per household, based on the current population for Kiewa/Tangambalanga for sewage treatment and disposal, is in the order I of approximately $290 to $300." In addition, there would be land costs for the sewage treatment and disposal. As well, there would be an initial capital cost for a reticulation system to capture the existing allotments in I Kiewa/Tangambalanga to discharge into the lagoons at an approximate cost of $900,000 to $1,00,000. An approximate cost per household based on the current population would be in the order of approximately $6,000. A gravity system for this internal reticulation system would be preferred I as there would be no operating costs. A summary of the key costs therefore, is as follows: I * Lagoon Treatment and Tree Irrigation $ 300 per household I * Initial Reticulation Cost $6,000 per household * Land Costs for Sewerage and I Disposal, say $100,000 $ 600 per household • Under the provlSlons of the Victorian Water Act, 1988, the Murray I Goulburn factory cannot be compelled to join a sewerage scheme. Their current system which comprises aerated lagoons and irrigation to land is in compliance with the Environmental Protection Authority licence. I WATER • The current chlorinated reticulated water system pumped from the Kiewa I River is approaching capacity in terms of available storage. There is currently a spare capacity for another 40 allotments to be serviced without major augmentation of the existing system. The priority of the I Lower. Kiewa Water Board is the construction of a new 5MI reservoir costing approximately $300,000 to cater for the ultimate population of 700 persons in 10 years time. The current pumping times could be increased to deliver the water requirements of the townships. I DRAINAGE I • Basic town drainage and outfall schemes are already in place. Construction of any new drainage system should preferably be undertaken in conjunction with construction of any new sewerage scheme with the system phased to commence construction from the downstream I pipe and continue construction upstream as funds become available. Cost estimates for a drainage scheme in Tangambalanga, based on existing developed areas, would be in the order of $490,000. I I I I r------------------------------------- I 3 3. Implementation of the Structure Plan and Services Review for I Kiewa/Tangambalanga lies with the responsibility of a number of key agencies. In respect of the Structure Plan, the prime responsibility rests with the Shire of Yackandandah to monitor change and undertake the necessary statutory land use I changes if and when required. Assistance and support could come from the Albury-Wodonga Region Planning Advisory Committee or the Department of Planning and Housing if required. In respect of the current services review which is aimed towards the development of a strategy, especially for sewage, the I prime responsibility lies with the Lower Kiewa Water Board in conjunction with the Shire of Yackandandah. The Lower Kiewa Water Board currently has full statutory responsibility for all of the water functions within its district: The I Department of Water Resources has advised that if a sewage scheme was to be implemented for Kiewa/Tangambalanga, either the Lower Kiewa Water Board or the Shire of Yackandandah would need to submit a proposal. The initiation I of any sewerage strategy by the Lower Kiewa Water Board or the Yackandandah Shire Council, or both, would need to be cognisant of the views of the residents of Kiewa/Tangambalanga as well as the current statutory changes regarding the I rationalisation of water boards in the Wodonga sub-region.

In addition, the population of Kiewa/Tangambalanga has reached a level I where appropriate structure planning is required, particularly in regard to options for sewage treatment. The Shire of Yackandandah recognised that if the strong growth is to continue, then the development of Kiewa/Tangambalanga needs to be undertaken via I an agreed Structure Plan, namely a plan indicating existing and future growth corridors in the context of existing constraints and opportunities and sound planning principles, as I well as developing a strategy for the provision of reticulated services.
