PUB is a statutory board under the Ministry of the Environment and Water Resources. It is the national water agency that manages Singapore’s water supply, water catchment and used water in an integrated way.

PUB prefers to be acknowledged as PUB, Singapore’s national water agency or PUB, the national water agency and not Public Utilities Board in public communication materials.

In just four decades, Singapore has overcome water shortages despite its lack of natural water resources and pollution in its rivers.

Driven by a vision of what it takes to be sustainable in water, Singapore has been investing in research and technology. Today, the nation has built a robust, diversified and sustainable water supply from four different sources known as the Four National Taps (water from local catchment areas, imported water, reclaimed water known as NEWater and desalinated water).

By integrating the system and maximising the efficiency of each of the four taps, Singapore has ensured a stable, sustainable water supply that is weather resilient, capable of catering to the country’s continued growth.

One of these Taps is the high-grade reclaimed water known as NEWater, a success story made possible by state-of-the-art membrane technologies. Such new technologies are a potential goldmine. The Singapore government has identified water as a new growth sector and will invest about S$330 million in water R&D in the next five years.

Besides its strategic role, water is beautifying Singapore’s landscape and improving Singaporeans’ quality of life. By involving people as stakeholders of the country’s water resources, we are moving closer to realising the vision of Singapore as a City of Gardens and Water.

What PUB does
As the national water agency, PUB is responsible for the collection, production, distribution and reclamation of water in Singapore.

Rainwater is collected through rivers, streams, canals and drains, and stored in 17 reservoirs. Various reservoirs are linked by pipelines so that excess water can be pumped from one reservoir to another, thus optimising storage capacity.

Raw water is piped to the waterworks for treatment.

After treatment, the water is stored in covered reservoirs before being distributed to customers.

Water that has been used by customers is collected via an extensive sewerage system and treated at water reclamation plants. Used water is a resource too – treated used water is further purified using advanced membrane technology to produce high-grade reclaimed water, known as NEWater.

With an eye on the future, PUB has built the Deep Tunnel Sewerage System (DTSS) for long-term sustainability. An integral part of the water loop, the DTSS is a superhighway that channels used water to a centralised water reclamation plant for treatment. The treated used water will then be discharged into the sea or further purified into NEWater.

Closing the Water Loop
From rainwater collection to used water treatment, the entire water loop is managed by PUB.

Safe To Drink From The Tap
Thanks to sound watershed management, effective water treatment processes and continued investments in R&D, Singaporeans have been enjoying good quality water for the last four decades.

Singapore’s tap water is well within the World Health Organisation's drinking water guidelines, and is suitable for drinking without any further filtration.

Our Mission
To ensure an efficient, adequate & sustainable supply of water.

Our Vision
Water for All: Conserve, Value, Enjoy.

Our Values

  • Value Conscious: We value our environment, our water resources and our people; and we ensure value for money in everything we do
  • Ownership: We do not merely represent PUB - Together WE ARE the PUB.
  • Innovation: We relentlessly pursue knowledge and innovate to create value.
  • Caring: Through respect and a positive work environment, we motivate our staff to develop their highest potential.
  • Excellence: We provide service to our customers with Professionalism & Integrity.


PUB has ensured a diversified and sustainable supply of water for Singaporeans through five strategic thrusts:

  • Water for All
  • Conserve, Value, Enjoy
  • Competence
  • Connections
  • Creating Value

The twin thrusts – “Water for All” and “Conserve, Value, Enjoy” encapsulated in PUB’s vision statement.

Water for All represents our commitment to ensure the robustness, reliability and sustainability of our water supply.

Conserve, Value, Enjoy projects PUB’s 3P approach in reaching out to our stakeholders and involving the community in our work.

Underpinning the above are the 3Cs, which drive how PUB formulates policies and programmes to fulfill our mission and vision:

Competence is about getting our people to be technically competent. It is about investing strongly in our people -- in training, technology and creating an environment where our staff can be innovative, highly committed, responsible and always daring to try new ideas. PUB’s ability to remain a leading water agency depends on us making sure we keep on developing our competence as an integrated water resource agency with excellent people at all levels of the organisation.

Connections is about connecting with our customers, with the community, with the industry, and with other countries in order that people understand us, and work with us. Connecting with Singapore residents is the key part of our mission, but increasingly, we also have to connect with the world to help bring about more business for our water companies, and to keep abreast with technology and best practices.

Creating Value is the essence of price-minus that PUB embarked on since 2004. It is not about cost cutting to save money for the short term. It is about making sure we give value and ensure the sustainability of our water resources in the most cost-effective way. PUB’s work is very capital intensive, so a key challenge of Creating Value is to find better ways to manage our assets, especially in our plants and networks.


The spirit of sharing and caring has always been an integral part of PUB’s culture. We believe in being responsible corporate citizens who make a difference to society. We focus our Corporate Social Responsibility (CSR) efforts in four areas as detailed in our CSR framework.

Corporate Philanthropy
PUB’s employees have been contributing to the SHARE programme since 1986 and are firm supporters of the Community Chest. In recognition of our long-standing commitment, ComChest awarded PUB its highest honour - the Pinnacle Award, in 2007.

PUB has also been a supporter of the Vertical Challenge - an annual fundraiser organised by the Ministry of the Environment and Water Resources, and PUB. Through active staff participation and generous donations, the Vertical Challenge raises funds for beneficiaries of the President’s Challenge.

Community Volunteering
Instead of monetary handouts, PUB helps needy families by installing water saving devices for them and educating them on water conservation. These visits organised in partnership with Community Development Councils (CDCs) and volunteers have helped them lower their utilities bills.

PUB adopts a focused approach to community volunteering by building long-term working relationships one charity at a time. From 2004 to 2007, we collaborated with Singapore Children’s Society. Towards the end of 2007, PUB adopted PEACE-Connect Neighbourhood Link (PCNL). This voluntary welfare organisation works with close to 600 registered seniors and children residing in one-room flats, some of whom are on public assistance. Examples of activities organised jointly by PCNL and PUB include visits to homes, sponsorship of tea breaks for the elderly, distribution of rations, and outings for children.

Responsible Business Practices
In carrying out its usual business operations, PUB believes in being responsible to both - the environment and its stakeholders. At the workplace, PUB staffs adopt simple yet practical eco-office practices, thereby conserving resources. For this effort, PUB was awarded the Green Office Label by the Singapore Environment Council in 2007.

PUB protects staff and stakeholders by minimising their health and safety risks, putting in place the OHSAS 18801 Occupational Health and Safety Management System. To further entrench the value of health, safety, security and emergency preparedness, PUB established a dedicated unit – Health & Security, Safety & Emergency Planning Unit, to look into and address related issues and risks.

Recognising that PUB’s operations will inevitably affect the environment in one way or another, PUB is mindful to minimise the adverse impact of its operations. To this end, we established the operationalised ISO 14000/14001 Environment Management System for all key installations.

International Responsibility
Reaching out beyond the local arena, PUB shares its expertise in urban water management with other countries and cities. Under an agreement with the World Health Organisation (WHO), PUB promotes the safe management of drinking water globally.

In addition, PUB also hosts study trips and conduct seminars to share water expertise with other international organisations e.g. UNESCO, UNEP, UN-HABITAT, Asian Development Bank and World Bank.

Last but not least, PUB offers its WaterHub as the Asia Pacific Regional Knowledge Hub, where developing countries can tap on PUB’s expertise, knowledge and skills.

In times of crisis, PUB has been quick to render assistance to other countries. In 2004, PUB raised funds and delivered about 3,000 water bags to victims of the South Asian tsunami, and shipped a desalination unit to the Maldives.
