PUB's Billing Agent
SP Services is PUB's billing agent. For efficiency, a consolidated bill showing the monthly utilities usage comprising water, electricity and gas is sent to customers. U-Save rebates are also credited to each HDB household's utilities account with SP Services.
Components of the Water Price
There are four components to the water price in the monthly bill: water tariff, water conservation tax, waterborne fee and sanitary appliance fee.
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 and Sanitary Appliance 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.
Currently, the Sanitary Appliance Fee (SAF) and Waterborne Fee (WBF) go towards meeting the cost of treating used water and maintaining the used water network. The SAF is a fixed charge based on the number of sanitary appliances in a household or premise. The WBF is charged based on the volume of water usage.
From July 2017 onwards, the SAF and WBF will be restructured into a single, volume-based fee. This is more reflective of the volume of used water discharged.
