1 Water Management in Phuket Water Management in Phuket

2 Introduction to Phuket Phuket is the most famous province in the Southern Thailand. It lies off the west coast of the Southern Thailand to the Andaman Sea. Its economy has been steadily expanding from the past until now. It formerly derived its wealth from tin mining. Now the tourism industry is the largest source of income in Phuket. Phuket

3 Water Management in Phuket Many water-related issues, such as flooding and shortage of water. potential negative impacts to its future economic development. Many large-scale water resource projects were already conducted: Bang Ward reservoir project (constructed in 1984) Bang Neaw Dam reservoir project (constructed in 2006) Klong Katha reservoir project (constructed in 2017) Still in short of water supply for the Phuket local population for ever-increasing inbound tourists.

4 Geography and Climate in Phuket Geography - The Phuket Province: the Phuket island, the largest island in Thailand, and 23 smaller islands - 543km 2-77% covered with mountains from north to south - 23% are plains lying in the central and eastern parts - Beaches in the east coast are more often muddy, while beaches in the west are sandy, which attract many tourists. Climate - Tropical monsoon climate - 7 months of dry season from mid-october to mid- May, with occasional rain - 5 months of rainy season - Average annual rain: 2,200 millimeters

8 1. Increase water reservoirs: (re)development of old small irrigation projects, mines, and swamps Solutions for water shortage issues 2. Improve the water retention rate of Bang Niew Dam 3. Provide more water to Bang Niew Dam 4. Develop the water drainage system between Bang Niew Dam Reservoir and Bang Ward Reservoir 5.Develop groundwater pumping 6. Transfer water from outside of Phuket

9 Solutions to Water Shortage in the Plan of the Royal Irrigation Department Quantity of water supply (million m 3 ) Items Improve the reservoir capacity of Bang Niew Dam Construct the water drainage system between Bang Niew Dam and Ban Khok Tanot Develop water exploitation from mines Develop water pumping of groundwater Improve the water retention rate of approximately 5% of annual runoff Estimated water supply increase Available water supply Total water supply Water demand Supply-demand balance

10 Water Pipelines of Phuket Provincial Water Work Authority Year Water Consumption in Phuket Volume of water production (Provincial Water Work Authority) Volume of water purchased from private sectors Volume of water production (Phuket Municipal Water Work Division) Total ,038,658 11,871,953 14,979,600 46,890, ,174,261 12,732,622 14,979,600 46,886,483 Local Population: 75,378 Annual Inbound Tourists: 13,306,455 (2016)

11 Solution by the Phuket Provincial Water Work Authority 1. To utilize private sectors to increase the water supply for the growing need. Raw water resources are provided for private sectors for water products. 2. To expand the number of water users in Kamala, Rawai, and Karon. 3. To improve the main water supply pipeline; particularly in Patong. 4. Phuket municipal water resource policy. To increase production capacity for the Phuket City and other neighboring areas.

12 Issues to Solve 1. Insufficient water supply for consumption both of the Phuket local population and increasing inbound tourists. 2. Incomplete area coverage by Phuket Provincial Water Work Authority and by Phuket Municipal Water Work Division. 3. Lack of land to expand the main waterline. 4. Lack of budget for water resource development and for service area expansion.

16 Government Policy: Policy Statement of the Council of Ministers (Friday 12 September B.E (2014)) 9. Maintaining the Security of the Resource Base and Creating Balance between Conservation and Sustainable Use 9.4 Manage the country s water resources in a unified manner in all dimensions, quantitatively and qualitatively; and provide a water management plan for the country and a process which integrates the work plans and budgets of all concerned agencies so that project work plans avoid redundancy, are systematically linked and conform with water resource management policy and direction, by establishing or designating water management mechanisms as well as using highefficiency technology in the water management and danger warning systems.

17 National Strategy 20 years ( ) Section 4: Development Strategies Strategy 4: Strategy for Environmentally-Friendly Growth for Sustainable Development Development Guidelines 3.3 Solve the environmental crises: speed up the control of air pollution, waste water, solid and harzadous waste from production and consumption. Build environmentally-friendly cities or green cities to create a good environment for the people. Related development guidelines should include

18 National Strategy 20 years ( ) Increase the efficiency of water quality management in the main watershed areas, particularly those facing pollution crises, by reducing wastewater from 139 the various sources. Accelerate the treatment of wastewater from households and industries. Decrease wastewater at source. Manage water quality within the entire systems: reuse treated wastewater for other purposes. Encourage Local Administration Organizations to operate wastewater treatment facilities: receiving wastewater from households and cities, collecting wastewater treatment fees to cover the costs of operation and maintenance (O&M), and monitoring and evaluating the efficiency of wastewater treatment systems.

19 National Strategy 20 years ( ) Promote the private sector to sub-contract from the public sector for O&M in wastewater treatment systems. Amend laws and regulations under building codes regarding wastewater sources. Set permit criteria and methods of releasing wastewater into receptive ecosystems within their carrying capacity.

20 Pollution Management Strategy and Plan ( ) Strategy 2 Increase the efficiency of waste treatment and disposal and pollution control at source. Prepare a master plan for community wastewater management Polluter Pays Principle: PPP Water saving/ reduce the volume wastewater Building Control Act Domestic Wastewater Management Beneficiary Pays Principle: BPP Wastewater rate Cluster wastewater treatment Create wastewater treatment plant
