With the implementation of new rural development policy and development of rural economic in China, water pollution becomes a serious problem in rural areas, which has been the major factor that leads to watershed quality deterioration and ground water pollution.
Through professional organizations to provide operation, maintenance is conducive to ensuring normal operation of the facilities, and facilitates the implementation of supervision.
The system can be operated by the municipal departments, also can be managed by private water cooperatives.
Rural water pollution problems seriously affect the safety of drinking water, which restricted the economic development of rural areas [7].
Liu Junxin made a investigation of the villages and towns in different areas of our country, which in terms of the social economy, water environment, water drainage, sewage disposal, the demand will and constraints.

Water jetting was completed throughout the test.
The water jetting involved adding water to the sand body within the centrifuge package.
No net water should leak into the package because the added water drains through the sand and into the standpipe where the water level was held constant using two drainage holes.
Both of PPTs were monitoring the water column in the standpipe, which should remain a constant water level throughout the whole test process as mentioned above.

Current pollution situation of Xiawan stream 1.1 Surface water of Xiawan stream According to the results of water quality monitoring in 2009, using pollution water releasing principle, there are Ammonia, suspended solids, chemical oxygen demand, biochemical oxygen demand, fluoride, phenol and Phosphorus in the water and all of them are exceeded.
Based on current heavy metal pollution situation of Xianwan stream, combine the treatment strategy, follow methods could be considered: firstly, water flow of Xiawan stream need to be cut off and change direction, and then, clean the silt one section after the others, the silt should be transfer to professional factory to make it stable and the water which come from this process need to be deal with also.
In the area where the surface water is wild, wetland can be design to purify the water and provide places for leisure and entertainment. 3.1.3 Longitudinal design of channel Length of Xiawan stream is 4.26km, width is 4-10m and depth is 0.5-1.5m, the measure of water area is 11.85km², average flow is 4.3m³/s, the water ecological environment is closed and flow is slow.
Rebuild the green infrastructure can use plants to clean the water.
Water area can be widen in some open water location, combine relative technology to create biological pond and choose the plants such as such Water hyacinth, water celery, rye grass, cattails and other which can absorb the heavy metal elements.

Modeling and by professional software can greatly increase efficiency.

In the paper, it focuses on the water damage to building application area.
The detection temperature range of water leakage is not specific.
To express professional conclusion on defect severity and certainty by using simple different levels, the following rating and certainty level are defined.
Obvious water drops can be seen.

Generally, when the water-saturated concrete was in the process of freezing-thawing cycle, it was suffered by the stress mainly consists of two parts, one is caused due to the volume expansion of water to ice, it cause the tensile stress in the microstructure, the other is when the water freezes in the wool stoma, the supercooled-water migrated may cause the osmotic pressure to the microstructure.
Water reducing agent.
Water reducing agent is a surface-active substance, it absorbs with cement particle and makes cement particle electrical.
These water-reducing agent can greatly reduce the water-cement ratio,[2] and significantly reduce the consumption of water, reduce the bubble size and average distance.

After data collection，the system software WinRiver have the playback function , flow rate, area, river width, average velocity of flow, average depth of cross section, the maximum velocity of cross section, maximum water depth, etc all can be obtained directly from the playback software , And the equivalent velocity figure along the track can be directly get.
But if we want to get the whole area of the flow distribution and the Contour map of underwater topography, rely solely on system software is unable to realize, should to use professional drawing software.
The rapid data extraction technology of ADCP In order to extract ADCP survey data quickly, we have developed a data extraction model of ADCP, named read_winriver，its main function is to extract data from the original data files with each layer depth of latitude, longitude, water depth, velocity value.
The conversed data files including longitude, latitude, water depth, velocity value, can be applied to draw the flow distribution and the Contour map of underwater topography directly.
Today, it is widely applied in meteorology, environment, geography, water conservancy and other disciplines.

The phreatic water and perched water in the underground water have the great effects on the underground garage.
In abundant water period, water soares, and the runoff of water is large; while in dry season, water level drops, and the runoff of water is small.
