  • 8. Opportunities

    1. PWA enables the private sector to invest in numerous affairs which benefit PWA. This also helps alleviate PWA’s burden of investment and enhance service efficiency in terms of quickness and is in compliance with the government policy which encourages the private sector participation in public affairs.
    2. PWA has the status of state enterprise and gets the confidence of water consumers in respect of service efficiency and water quality, compared to that of small-scale private providers or local governments.
    3. PWA can proliferate its business, for instance, establishing a subsidiary company producing bottled water or wholesaling raw water to the industrial sector.
    4. The government supports and promotes industrial distribution to all regions of the country, raising a higher demand for water supply in the area.
    5. The government has a policy supporting the budget for providing a larger amount of clean water to regions and rural areas.
    6. The country’s economic growth stimulates larger urbanization and thus increases the demand for water.
  • 9. Threats

    1. The area under PWA’s responsibility is typically sparsely populated and people live far away from one another. Accordingly, PWA usually needs a huge amount of budget for its work implementation and investment in the pipeline installation and water sources procurement.
    2. PWA’s financial standing has its limitations, making it unable to extend its work to meet the public’s demand. Furthermore, the Government’s subsidization is not adequate and therefore it needs the private sector to take part in some activities or projects.
    3. PWA’s personnel specializing in a particular field are insufficient to implement the plan defined since the wage or salary is not persuasive, stemming from a small remuneration given to staff.
    4. PWA’s no-revenue water (NRW) is high since old pipe replacement or new pipe installation can’t be carried out all at one time due to high expenses. So it has to be done gradually to create a minimum impact on PWA’s current consumers. Virtually, the NRW reduction process needs a continuous inspecting and corrective measure, which is a great burden on PWA’s part, particularly to PWA branches having a large number of old pipelines or inadequate staff to cope with the pipeline maintenance.
    5. PWA’s current water tariff rate is still lower that the operation cost and has not been adjusted to a higher rate which reflects actual production costs.
    6. PWA’s work performance is inflexible due to its rules and regulations like those applied in the government sector.
    7. At present, Thailand has no laws controlling and allocating the use of water from different water sources, both surface and ground water, causing those water sources to have both decreasing amount and degrading quality, including less availability in the future.
    8. The public lacks an understanding of the service of an agency having 2 aspects of its mission, namely, social service emphasizing people’s happiness, and service in a business manner, which has to be self-sufficient in parallel with business extension in the future.
