In Korea, the current water resources will fall short by 2.6 billion tons to meet the 38 billion ton water demand in the year 2020. To overcome the future water shortage, it is desirable to minimize water consumption and to reuse treated wastewater. There are a total of 99 on-site water-recycling systems in the country. The potential capacity of the 99 systems is 429 thousands tons/day, which is 3.6% of the total service water. Compared to other industrialized countries, the number of the water recycling systems in Korea is extremely small. This is mainly due to the following reasons. First, in Korea, any building with more than 60,000 m2 of total floor space is required to install a water reuse system by law. However, only less than 0.5% of the total buildings have more than 10,000 m2. Therefore, the regulation is ineffective and merely nominal. Second, service water is supplied at low charge (0.20 US-dollar/m3 water). The inexpensive service water often discourages people to recycle treated wastewater. Third, people still think recycled water is not clean enough and can cause diseases. Therefore, they should be informed that a well-maintained recycling system does not fail to produce water with high quality.
