Since water demand in 2011 was 380 million imperial gallons (1,700,000 m 3) per day, Singapore could actually already have been water self-sufficient in 2011 except in years of very low rainfall. The official figures downplay the share of reclaimed and desalinated water in water supply, and thus the ability of the country to be self-sufficient.
Since the founding of Singapore in 1819, more than 95% of its estimated 590 square km of vegetation has been cleared. At first for short-term cash crops and later because of urbanization and industrialization. 61 of its original 91 bird species has been lost leading to many native forest plants not being able to reproduce because of loss of seed dispersal and pollination.
Population equivalent (PE) or unit per capita loading, or equivalent person (EP), is a parameter for characterizing industrial wastewaters.It essentially compares the polluting potential of an industry (in terms of biodegradable organic matter) with a population (or certain number of people), which would produce the same polluting load.
Main sectors, as defined by ISIC standards, include agriculture; forestry and fishing; manufacturing; electricity industry; and services. This indicator is also known as water withdrawal intensity. [4] According to Food and Agriculture Organization, ″total freshwater withdrawal is the sum of surface water withdrawal and groundwater withdrawal ...
There are higher proportions of plastics, metals, and paper in the municipal solid waste stream and there are higher labour costs. [1] As countries continue developing, there is a reduction in biological solid waste and ash. [2] Per capita waste generation in OECD countries has increased by 14% since 1990, and 35% since 1980.

The total capacity of the plants is about 200 million US gallons per day (760,000 m 3 /d). About 6% of this is used for indirect potable use, equal to about 1% of Singapore's potable water requirement of 380 million US gallons per day (1,400,000 m 3 /d).
These include desalination and water reclamation aimed to meet at least 25 per cent of Singapore's water needs by 2012. The Public Utilities Board planned to secure 136,000 cubic metres of desalinated water per day by the year 2005 to produce NEWater. By 2010, the supply of NEWater to the industrial and commercial sectors is expected to exceed ...
