That is including infants children aged disabled etc no income persons, therefore each earning adults pro-rata pays even more to cover them.

MEMBERS of the public can expect earlier warnings about heavy rain and potential floods in the future, as national water agency PUB unveiled a flood-prevention action plan yesterday.
For instance, images from selected closed-circuit TV (CCTV) cameras - from among the 61 installed islandwide to monitor flood-prone areas - will be made available on PUB's website by March.
These CCTV cameras include those in Cuscaden Road and Shenton Way, and will enable the public to have a better idea of areas to avoid in the event of a flash flood.
PUB also said it will spend about $750 million over the next five years to carry out 20 drainage-improvement projects.
These projects include increasing the capacity of six major canals: Bukit Timah First Diversion Canal, Geylang River, Alexandra Canal, Rochor Canal, Sungei Bedok and Sungei Kal- lang. Their capacities will be increased by 30 to 45 per cent through widening and deepening works.
Measures will also be taken within the year to increase the capacity of Stamford Canal, which was blamed for the Orchard Road floods last year and in 2010.
These measures comprise: Smoothening the canal walls to reduce friction, and removing sewer and Newater pipelines. These will increase the canal's capacity by 10 per cent.
For the long term, PUB will also finalise by May whether to build a diversion canal or a water-storage pond to ease the canal's load.
These drainage-improvement plans were announced yesterday, following recommendations made by an expert flood panel earlier this month.
PUB also aims to roll out a pilot flood-forecasting system in the next two years - based on information from cloud patterns, rainfall and water levels - to provide warnings on where and when floods may occur.
It is not known how much earlier these warnings can be issued, as the system has yet to be tested. However, PUB's chief executive, Rear-Admiral (NS) Chew Men Leong, said that warnings will be useful even if they are issued minutes before a flood occurs.
He said: "There is a whole range of measures which can help (members of the public) prepare and not get into flooded areas, which also helps us in terms of the management and mitigation of the impact of the flood."
PUB currently updates its website and social-media platforms with notifications on high-flood-risk areas and flash floods that have occurred.
It was also announced that the Meteorological Service Singapore will enhance its heavy- rain warning service to allow earlier warnings to be issued. It is expected to be introduced later this year.
To tackle the effects of increasing urbanisation on flooding, PUB said it plans to develop guidelines for new buildings within the year.
The agency also added that it will review its drainage masterplan once every three years, instead of its current practice of doing so once every five years. The masterplan will be made public next year.
RADM Chew said that, while some environmental changes may not fully manifest themselves within three years, reviewing the masterplan more often will "help us keep on top of the changes".
