Water Price

Effective Water Pricing

Water is a precious resource, and its prudent use is key to our water sustainability.  

Water pricing is an important and effective mechanism to reflect the scarcity value of water. Water is priced not only to recover the full costs of its supply and production, but also to incorporate the higher cost of producing water from unconventional sources, specifically NEWater and desalinated water. 

The water price was last revised in 2000, over the period from 1997 to 2000.

Water Price Revisions

The water price is revised in two phases. The first phase took place on 1 July 2017 and the second revision on 1 July 2018. 

Heavy investments in water infrastructure, coupled with rising operational costs, have made the increase in water price necessary. We are upgrading our water system to make it more resilient, especially to face the challenges posed by climate change. The revised water price will enable PUB to cater to future demand, strengthen Singapore's water security, and continue to deliver a high quality and reliable supply of water.  

The water price goes towards meeting the cost of water treatment, reservoir operations, NEWater production, desalination, used water collection and treatment, as well as the maintenance and expansion of the island-wide network of water pipelines. 

It also includes the Water Conservation Tax (WCT), which is imposed on the potable water tariff. The WCT reinforces the message that water is precious. This tax is also to reflect the full incremental cost of producing more potable water (likely by desalination and NEWater) beyond PUB's present output, so that consumers are conscious of the scarcity value of the water they use.

Assistance for Eligible HDB Households

GST Voucher-U-Save

At the same time, the Government had in July 2017 permanently increased the annual GST Voucher - U-Save rebate for eligible HDB households by between $40 and $120, depending on the flat type. 

In total, eligible HDB households receive between $220 and $380 in U-Save rebates per year, which are automatically credited to their utilities account. The average change in water bill after increased U-Save rebates is given in the table below.

Water Efficiency Fund

In 2007, PUB launched the Water Efficiency Fund (WEF) to encourage organisations to seek out efficient ways to manage their water demand. Organisations or companies who are interested to implement water efficiency projects can tap on the WEF, which provides funding support for feasibility studies, water audits, recycling efforts, use of alternate sources of water and community-wide water conservation programmes.

PUB's Billing Agent

SP Services is PUB's billing agent. For efficiency, customers receive a consolidated monthly utilities bill for their water, electricity and gas usage. U-Save rebates are also credited to each HDB household's utilities account with SP Services.

Components of the Water Price

There are three components to the water price in the monthly bill: water tariff, water conservation tax and waterborne fee.

Water Tariff

The Water Tariff covers the costs incurred in various stages of water production process — collection of rainwater, treatment of raw water and distribution of treated potable water to customers through an extensive island-wide network of water pipelines. The Water Tariff is charged based on the volume of water consumed.

Water Conservation Tax

The Water Conservation Tax (WCT) was introduced in 1991 to encourage water conservation and to reflect its scarcity value. WCT is imposed as a percentage of the water tariff to reinforce the message that water is precious from the very first drop.

Waterborne Fee

Every drop of used water is collected via a separate network of sewers and channelled to the water reclamation plants for treatment, after which it is further purified into NEWater or discharged into the sea.

The Waterborne Fee (WBF) goes towards meeting the cost of treating used water and maintaining the used water network. It is charged based on the volume of water usage.
