Factor Affecting on Sustainability of Water Supply (Case Study on Buaran Water Treatment Plant in the City of Jakarta) (original) (raw)

In the past, municipal water supply systems generally comprise collection works, purification works, transmission works and distribution works which are concerning with engineering aspect. Population growth, industrialization, economic growth and the development of quality of life are some example in increasing demand of water supply. To fulfil the need for water supply, not only depend on engineering aspect but also another aspect should be taken into account. Integrated water supply system approach which will consider natural environment, engineering aspect, and socioeconomic and community participation aspect should be applied. Characteristics of raw water, water treatment technology alternative, water production cost, willingness to pay, implementing and law enforcement on current regulation are other aspect to be considered in sustainability of water supply system. Nowadays, river is the main alternative of source of water among other sources of raw water. However, characteristic of the surface water has been setting worst basically caused by people activities as well as the effect on climate change. Adaptive technology should also an option to accommodate the change of characteristics of the raw water in produce safe water. In general water treatment plant in Indonesia was constructed for 15 and 40 years ago. The development on water treatment plant technology to produce drinking water that meet drinking water standards will affect to the water production cost as a result will also affect to willingness to pay of the water supply consumer. Many regulation concerning with water supply have already been set up and produced which is not only protecting the water resources and the environment from pollution, but also managing the community as well as government obligation.
