Sanya River

The third largest river in Sanya is composed of liuluoshui, shuijiaoxi and banlingshui. With liuluoshui as the main stream, it originates from the south foot of the high mountain on the right side of zhongzhongling mountain at the junction of Sanya City and Baoting Li and Miao Autonomous County. It flows from north to South and flows into Sanya port through Sanya City.

Sanya River

Sanya River, located in the south of Sanya City, is composed of three rivers, liuluoshui, shuijiaoxi and banlingshui, with liuluoshui as the main stream. The three rivers converge, pass through the city from north to south, and flow into Sanya port to the sea, with a total flow of 28.8 kilometers and a drainage area of 337 square kilometers.

The reason why it is called Sanya River is that it is divided into East River (24.8 km in total length) and West River (31.3 km in total length) near the mouth of the sea. The shape of the place where it flows into the sea is "Ya" shaped. "Ya" shape is a good natural harbor. The people who settled here vividly called the river "Sanya River", and later gradually called it Sanya River. Sanya River has also become the "Mother River" most closely related to Sanya's urban life.

Sanya River is also the third largest river in Sanya. Sanya is named after Sanya River. People live in two rivers and three banks. It can be said that Sanya River is the river most closely related to Sanya city life.

Formation and change

Sanya River is composed of three rivers, liuluo River, Shuijiao River and Banling river. Liuluo river is the main stream. It originates from the south foot of the high mountain on the right side of the middle ridge at the junction of Sanya City and Baoting Li and Miao Autonomous County. It flows from north to South and flows into Sanya port through Sanya City. The flow is 28.8 km and the drainage area is 337.02 square km.

Main stream situation

Donghe

With a total length of 24.8 km, it stretches along Yingbin Road to the depth of lizhigou and is blocked in the upper reaches to form Banling reservoir and Caoping reservoir.

Xihe

With a total length of 31.3 km, it passes through Yuechuan bridge and Jinjiling area, and then is divided into two branches. The one with less water flows to Gaofeng area through Yanglan, and the upper reaches are blocked to form Tangta reservoir. The liuluo River, which has a large amount of water, irrigates thousands of mu of land through the vast miaolintianyang. Liuluo river passes through Binglang village, which is named Binglang river.

Liuluo River

Liuluo River, which flows through the reservoir of water source pool and into the sea through Sanya River, is usually regarded as one of the main sources of Sanya River.

Hydrological facilities

Fuwan reservoir

Sanya Fuwan reservoir was built in 1980, is the first phase of Sanya City water supply project, located in Fenghuang Town, 19 kilometers away from the urban area. Fuwan reservoir has a rainwater collection area of 33.25 square kilometers, a total storage capacity of 11 million cubic meters, a normal storage capacity of 10.1 million cubic meters, and an annual raw water supply capacity of 10.074 million cubic meters, providing the raw water demand of lizhigou water plant and Jinjiling water plant. Water quality: Iron and manganese sometimes exceed the national environmental quality standard for surface water (GB3838-2002), oxygen consumption and volatile phenols fluctuate within the class I - III standard, and other items meet the class I - II standard.

The buried culvert from Fuwan shuiyuanchi reservoir to lizhigou waterworks is a masonry culvert with a width of 0.8 m and a height of 1.2 m, with a total length of 12.5 km and a design water delivery capacity of 30000 m3 / D; the water delivery pipe from Fuwan shuiyuanchi reservoir to Jinjiling waterworks is a DN800 concrete penstock with a total length of 8.6 km and a design water delivery capacity of 52000 m3 / d.

Water source reservoir

Sanya water source reservoir was built in 1990, is the second phase of Sanya City water supply project, located in Fenghuang Town, 10 kilometers away from the urban area. The rainwater collection area of shuiyuanchi reservoir is 53 square kilometers, the total storage capacity is 14.9 million cubic meters, the normal storage capacity is 13 million cubic meters, and the annual raw water supply capacity is 15.111 million cubic meters, which provides the raw water demand of lizhigou water plant and Jinjiling water plant. Water quality: Iron and manganese sometimes exceed the national environmental quality standard for surface water (GB3838-2002), oxygen consumption and volatile phenols fluctuate within the class I - III standard, and other items meet the class I - II standard. The buried culvert from Fuwan shuiyuanchi reservoir to lizhigou waterworks is a masonry culvert with a width of 0.8 m and a height of 1.2 m, with a total length of 12.5 km and a design water delivery capacity of 30000 m3 / D; the water delivery pipe from Fuwan shuiyuanchi reservoir to Jinjiling waterworks is a DN800 concrete penstock with a total length of 8.6 km and a design water delivery capacity of 52000 m3 / d.

Fuwan reservoir and shuiyuanchi reservoir belong to the upstream and downstream reservoirs of the same river.

Tributary reservoir

Besides the water source reservoir and Fuwan reservoir in the main stream, two medium-sized reservoirs, Banling reservoir and Tangta reservoir, have been built on the two tributaries of Sanya River. Banling reservoir was built in 58. At that time, irrigation was mainly used. Later, due to urban development, urban water supply was increased in 1993. The four reservoirs in the upper reaches of the Sanya River supply about 100000 tons of water to the city every day, irrigate nearly 20000 mu of farmland in the lower reaches, and generate 11 million kilowatts of electricity annually. In the flood season, especially in the typhoon season, they also play an important role in retaining the flood peak and protecting the people in the lower reaches. Although with the development of the city, these four reservoirs have gradually lost their important position in the past, their contribution to the development of the city is worth remembering. "One dam crosses the liuluo River and gathers sweet springs to run thousands of families". The reservoir is like a loving mother, nurturing and protecting the children of Sanya. While enjoying the dividend of urban development, we should always think about the clear water in the deep mountains.

Governance and development

2015 is Sanya's "year of urban governance and management". Governance and management is very important for Sanya to build an international tropical coastal tourism city, improve the level of city governance according to law, and upgrade its archives. Like the "five key battles", the renovation of Sanya Bay, Sanya River, Linchun River, Yingbin Road, Fenghuang road and Yuya road is also an important task of Sanya management year. Sanya has taken a variety of measures to vigorously renovate the "one bay, two rivers and three roads". It will also unremittingly seek long-term strategies to make Sanya's sea, sand, river and road livable elements.

With the continuous development of Sanya City, the ecological environment of Sanya River is not optimistic, and the problems of sewage drainage, river garbage stacking, and river occupation are prominent. However, Sanya has made unremitting efforts in pollution control, such as issuing tickets to illegal discharge enterprises, declaring war on pollution discharge through multi department linkage, and the leading group has repeatedly deployed pollution control work to promote the pollution control management of Sanya River. In addition, we have formulated the pollution control plan, proposed eight pollution control tasks including improving the sewage collection and treatment system in the central urban area, played a heavy role in pollution control, emphasized the responsibility of the whole chain, carried out the pollution control to the end, and returned the green water and green waves of Sanya River.
