Currently, the water supply system in Ho Chi Minh City with a total capacity of 1.2 million m3 / day, which is added from the water supply system of the Saigon River, Phase I is 250,000 m3 / day (in capacity design of 300,000 m3 / day); Besides Thu Duc Water Plant II (NMN Thu Duc BOO) capacity of 300,000 m3 / day, Kenh Dong Water Supply will move 150,000 m3 / day of Tan Hiep Water Treatment Plant to supply water to the city. However, the water supply system has not grown up enough to provide 100% water, and most current production is in the near future, as the demand for water over the next 7-8 years may be up to more than 2,400,000 m3 / day. To meet the water demand of immediate and future continuing renovation and new construction of the existing water system is extremely urgent, the principle should be followed when implementing investment projects on construction is to follow strictly a master plan for long-term water supply systems have been taken into consideration.
the system's water distribution current city, mainly covered only the urban areas, suburban parts less systematic water supply. However, even within the city water supply is sometimes interrupted and the water pressure is too low compared with demand. Only counties east and central regions in general have sufficient water supply pressure, while District 6 and District 8 State rarely. The main cause of the weakness and inefficiency of the existing distribution network is defined as:
i) a high amount of water loss, approximately 38% of production, is the main cause leaks on the pipeline network, particularly when the tube has been used for over 50 years.
ii) the system is too small diameter pipe than required causing hydraulic losses are very high.
a complete water system, safe and reliable would be a of the prerequisites to attract investors, to ensure the sustainable development of other economic sectors, so immediate and long term, an urgent need to be implemented as soon as construction and comprehensive development of the city water supply system under a long-term master plan as described above. State and city People's Committee are aware of this situation in the past year should have given high priority to the implementation of a program of rehabilitation and expansion of water supply systems Tp.
In some cases the investment in the construction of water supply systems just interested in the task and require immediate, not built up long-term development programs, in compliance with the conditions of socio-economic development, the needs of people water use and the ability to meet the water supply system. Many water supply systems are built in a patchwork manner, not according to a certain plan. To be able to plan is a plan to invest in developing water supply system in a reasonable manner in all phases: selection of water resources, development of water power plants, expand the network of pipelines, preventing revenue loss losses, improve operational management, to avoid breaking the balance of the entire system between the power plant and water pipeline networks; The size of the system and management level, between supply and demand, between regions, between the stages of construction and development, requires a long-term development planning accordingly. Therefore, the Government has requested financial support and engineering from the Asian Development Bank (ADB). Year 1995-1996 experts gkw consulting firms, and VIWASE Safege Asian Bank was appointed to conduct the study overall planning of water supply system in Ho Chi Minh City to 2010 period, reports this was completed in 1996. this adjustment mainly modify convey pipe network, pipe grade I for the period 2005, 2010. After adjusting Not so content December 24, 2001, the Prime Minister issued decision No. 1600 decision / QD-TTg approving the master plan for water supply in Ho Chi Minh city to 2010 period and orientation until 2025.
