A change of paradigm is needed in southeast asia with a holistic approach giving due regard to the requirement of equitable distribution of water, adequate governance, efficient economic performance and maintenance of environmental quality.
In Australia clean and filtrated water is made available to nearly all household, but in south east Asia only an amount of people is able to access clean water. As NSW water is made available to customers via credits to the accounts attached to their water access licences. Water NSW manages a complex network of dams, storages and pipelines to supply water to its customers. Available water determinations are made by the NSW Office of water according to the rules in place for the water sharing plans. In southeast Asia 86% of the whole population is able to use an improved water source which is their main source of drinking water. south east Asia not only has food supply problems but also, inadequate access to safe and affordable drinking water and sanitation facilities for all and also the degradation of environment in catchments. Trends in the proportion of population using either, a piped connection on premises, another improved water source or unimproved drinking water source, urban, rural & total, 1990-2006.
Water systems in both nations try to prevent unwanted substances from entering water. Water systems throughout NSW, Australia are through dams and reservoirs, water supply weirs, water filtration plants, water recycling plants and Sydney desalination plants. Water NSW manages a complex network of dams, storages and pipelines to supply water to its customers. For ASEAN the system they have attempted to adopt is to develop a consolidated water resource (river) organisational system and associated water quality standards. This system is user based and does not consider the protection of the resource base. It is suggested that the organisation of the water rivers to be extended to reflect various levels of protection and conditions that are needed to be met to achieve any designated class. Ian important aspect is to consider the requirements made on trade regulations as well as socio-economic aspirations and ecological constraints. To provide a consistent framework in which water river can be organised each class representing a different level of protection and provide a potential service. There have been a number of strategies proposed to organise this water system none of them seen to carry out any good outcome that suits the situation.
86% of southeast asia's population now uses an imporved source a their mains source of drinking water.
NSW and southeast Asia do have issues regarding water sanitation. Issues surrounding southeast Asia’s water management system includes water supply, sanitation, floods and droughts, degradation of the environment, food security, livelihoods of the poor, and the increasing variability is due to human intervention and changes in climate. All these factors contribute to how not all of southeast Asia has access to clean and sanitary water.In NSW issues that can occur if water in dams were to be affected would be, faces, pesticides, fertilizers or any other chemicals entering the water. if any of these chemicals were to enter the water it would have an effect on the ecosystems, and could trigger an algal bloom. This could effect the ecosystem that live in the dam, the ecosystems that live in the dam also help with the filtration process before entering the existing filtration process. If chemicals entered the dam it could trigger an algal bloom as certain chemicals such as phosphorous and nitrogen can cause algae to grow and develop. If algae do grow it can harm the water flow and temperature of the water in the dam. This could have some consequences on the water and how it comes through the filtration process and how it is accessed.
