PUB's watershed management and treatment processes has ensured a continuous supply of clean and quality water for Singaporeans over the last four decades.

Three reservoirs in Singapore are named after notable Municipal Engineers James MacRitchie, Robert Peirce and David J. Murnane.

The idea of a Public Utilities Board was first introduced in 1961 when industrialisation was driving up the country's demand for power.

Today, the PUB is solely in charge of water supplies with the management and control of electricity and gas transferred to the Energy Market Authority (EMA).

[9] In the production process, raw water from the reservoirs is piped to the waterworks to be treated with chemical coagulation, rapid gravity filtration and chlorine disinfection.

These procedures remove harmful particles and suspended particulate matters from the raw water, making them safe for consumption.

With the development of the deep tunnel sewerage system (DTSS) aimed for completion in 2022,[10] sewage will be conveniently transported to three water reclamation plants for treatment.

The Four National Taps form the backbone of PUB's, and in turn Singapore's, water management strategy.

Singapore's rainwater is collected and stored in 17 reservoirs using an extensive network of drains, rivers and canals.

PUB makes use of online sensors and sampling methods to monitor the quality of raw water it is treating.

It is scientifically tested to have surpassed the World Health Organization's requirements for safe drinking water.

PUB also plans to utilize this channel to create awareness of the concept and application of its programmes amongst industry experts in hopes to attract and train professionals to design and implement this project.

These businesses will also have to submit their WEMP to PUB annually for the next 3 years to ensure adherence to the requirement.

PUB's employees have been supporting the virtue of corporate philanthropy by consistently and steadily contributing to the Share Programme[16] under the Community Chest since 1986.
