Overview of IWRM in Thailand

In terms of priority the top three key water management issues in Thailand are as follows:

  1. Adequate water supply (Drought)
  2. Flood
  3. Water Pollution

The following is an overview of the IWRM status in Thailand for the six key water management issues.

  1. Water Supply Management

The key issues in water supply management are as follows:

  1. Reducing the leakage in the water supply piping system by installing water leakage management application
  2. Natural and anthropogenic pollution impacting the water quality of the raw water supply

The figure below shows the status of water supply management in Thailand for 2010 and 2013 for six key indicators.

  1. Irrigation Management

The key issues in irrigation management are as follows:

  1. The size of irrigated area is increasing slowly because most of the potential area for irrigation has already been developed and it is very difficult to develop irrigation reservoir because the people are against dam construction projects.
  2. The challenge is climate change, water demand management and technology for irrigation management at basin level.

The figure below shows the status of irrigation management in Thailand for 2010 and 2013 for three key indicators.

  1. Stormwater Management

The key issues in stormwater management are as follows:

  1. The legislative provision is weak on capacity building and awareness.
  2. The challenge is integration between the various agencies’ plans for stormwater management.
  3. The need for protection or urban areas from flood risk from stormwater.

The figure below shows the status of stormwater management in Thailand for 2010 and 2013 for six key indicators.

  1. Flood Management

The key issues in flood management are as follows:

  1. Flood management involves a lot of step such as data measurement,  data collection, data analyzing, decision support system, warning system and institutional network and communication.
  2. The challenge is the integration of the flood management plan and integration of the plans by different agencies before, between and after the flood occurs.
  3. The achievement is government, agency and people increased awareness.

The figure below shows the status of flood management in Thailand for 2010 and 2013 for nine key indicators.

  1. Water Pollution Management

The key issues in water pollution management are as follows:

  1. Policy exists at all levels of government for water pollution management
  2. The current government policy is for river basin based management.
  3. Drafting of the Water Quality Management Strategic Plan
  4. Formulating a Specific River Basin Action Plan in parallel

The figure below shows the status of water pollution management in Thailand for 2010 and 2013 for nine key indicators.

  1. Water Sanitation Management

The key issues in water sanitation management are as follows:

  1. Have constructed WWTP for large cities and in progress to cover city expansion
  2. Local Authority Offices still need capacity building on technical knowledge

The figure below shows the status of water sanitation management in Thailand for 2010 and 2013 for nine key indicators.
