Water use has been growing globally at more than twice the rate of the population increase over the last century. Water scarcity is one of the main problems facing the world, especially the scarcity of clean and safe drinking water. Scarcity of drinking water is not only relevant in arid or semiarid regions, but also occurs in water-rich regions due to the decline in water quantity caused by pollution or salinity intrusion. As a part of Taihu Lake Basin, a famous water-rich region in China, Yixing City has a total area of 1996.6 km2, including 242.29 km2 from Taihu Lake, 215 rivers with an area of 130 km2, more than 20 ponds with an area of 0.05 km2, and 20 reservoirs with a total capacity of 126 million m3. There always has enough water in Yixing City. However, meteorological conditions and water quality both affect the available drinking water sources. Poor-quality water was used as a drinking water source in Yixing City during a drought event in 2011. Approximately 1.4 × 107 m3 of poor-quality water was used for drinking water in Yixing city, providing 37.13% of the total drinking water. It was a source of concern that the water quality was too poor to be used as drinking water and that the water treatment processes were expensive. The scarcity of drinking water has become a serious issue, not only in arid and semiarid regions but also in water towns such as Taihu Lake Basin, and this issue requires society’s attention. Many measures should be taken to relieve the drinking water shortage, such as seeking new drinking water sources, protecting the current water source areas, controlling pollution emissions, and implementing effective water resource management.
