Where does Sanya's fresh water come from? Can you tell me?

The fresh water in Sanya is supplied by surface water, mainly by reservoirs.

There are six drinking water supply reservoirs in Sanya, namely Chitian Reservoir, Fuwan Reservoir, Shuiyuanchi Reservoir, Baogu Reservoir, Ban Ling Reservoir and Dalong Reservoir. Fuwan Reservoir, Shuiyuanchi Reservoir and Ban Ling Reservoir are responsible for providing raw water to Lizhigou Waterworks and Jinjiling Waterworks. Chitian Reservoir is responsible for supplying raw water to Qingtian Waterworks; Baogu Reservoir and Dalong Reservoir are responsible for providing raw water to Yacheng Water Plant.

In addition, there are abundant groundwater resources under Sanya Island, and even "in Sanya, the fourth, fifth, sixth and seventh layers of confined water at 40℃ to 50℃ can be extracted by drilling a deep well of 500-800 meters, which is also commonly known as' hot springs', and the water is rich in trace elements beneficial to human body".

At the same time, most of Sanya is covered by vegetation. Of course, these plants live on fresh water, and their roots are deeply rooted in the ground, which can of course form a large area of groundwater resources reservoirs and rivers.

Since the establishment of Sanya City, the Sanya Municipal Party Committee and Municipal Government have taken measures to replenish fresh water for residents of various islands and reefs. Seawater desalination equipment was built one after another on inhabited islands and reefs to help countless saplings survive; The domestic sewage generated on the island reef every day becomes clear water, which can be recycled and used to water flowers and plants. The problem of "less fresh water" and "difficult draught" on the island reef has been solved.

At one time, in Yongxing Island, where the Sanya municipal government is located, the domestic water of the soldiers and civilians stationed on the island mainly depended on tap water, bottled water and bottled water sent by supply ships, as well as purified rainwater and groundwater. Tap water is mainly used for drinking and cooking. Bottled water and bottled mineral water are used as auxiliary drinking water.

The purified rainwater and a small amount of desalinated seawater are only used for bathing and laundry. The underground water on the island is yellow in color and contains many impurities, so it can hardly be used except for flushing toilets. Although the supply ship brought fresh water from Hainan Island, the drinking water problem has been alleviated to some extent. However, at that time, each supply ship could only transport 120 tons of fresh water, and typhoon weather would greatly affect the supply of fresh water.

Because of the lack of water, many jobs are also extremely difficult. Shi, director of Sanya Land and Resources Bureau, said that island reef greening is a key point of Sansha's work. However, in order to plant living vegetation on Xisha Island, it is difficult to charter a boat from Zhaoshu Island to transport fresh water to Xishazhou.

After the establishment of Sanya, it actively started to solve the water problem of islands and reefs. 20 14 12, Yagongdao Community of Sanya Yongle Islands Management Committee produced the first "seawater desalination water". The quality of the treated desalinated seawater has reached the national hygienic standard for drinking water, thus alleviating the shortage of fresh water resources on the island.
