Chapter II wisdom Water Development Trend
Water integration refers to the coordination between the functions and all aspects related to water management, unified management system, that area of flood control, drainage, water supply, water demand, water conservation, water conservation, wastewater treatment and reuse extremely, irrigation, soil conservation, water and electricity in rural areas, groundwater recharge and other unified planning, unified water licensing, unified configuration unify the crossing, unified management. That is responsible for water quality and quantity by the department.
Complete urban water works system include:
- Water supply system
- Water works;
- Water purification works;
- Water distribution networks.
- Drainage systems engineering
- Drainage network;
- Sewage treatment;
- Recycled water use (industrial, agricultural, life).
- Flood control and drainage engineering system
- Reservoirs, dikes, river, Storage Project, risk engineering, waterlogging works, pumping stations and other row of stagnation.
- Water ecology system
- To the drainage system: including water protection, water plants, water supply network, drainage and sewage treatment;
- Environmental systems: water pollution control, sewage treatment, urban ecological landscape water engineering;
- Disaster Prevention System: flood control, drought, waterlogging, fire.
All aspects of information sharing:
In order to better examine their own positioning water information from the global municipal water modernization work, the various aspects of the elements of the information involved as a whole into consideration and realize resource sharing and business collaboration objectives through standardized data and business application system model proposed to adapt information technology to promote the management mechanism reform and development of water demand, water supply information to guide current and future periods. Shall be subject to water information integrated system, standard frame construction information resource sharing and service water conservancy collaboration, clear water business systems and common platform to ensure the relationship between the environment and other basic support system, the formation of guidance and coordination of water information resources, business systems and construction and operation of security systems support, technical infrastructure, public service platform and software resources (data) has been built products take full advantage of the information resources accumulated by the system, the system has been built step by step. Conduct whole and sound, at the same time regulate and guide for the new system under construction.
The first step to implement a comprehensive daily supervision, real-time control of water environment
Perception basin through real-time data acquisition, wireless networks, and other online water quality monitoring equipment pressure gauge overall distribution of water flow, water quality, natural rainfall, artificial water storage, information domestic water, industrial water, agricultural water, sewage, etc., to form a "city water things ", documented, comprehensive monitoring, and then shared with municipal, enterprises, institutions and public parties.
Mathematical model of mass data collection to get them quickly process and analyze the results and make the appropriate treatment decision support recommendations for a more refined and dynamic management of the entire production, management and service process water system. Government, Water Authority, water companies, sewage treatment and the Ministry of Construction companies can use three-dimensional visual way of rational planning and agricultural irrigation in the basin plant number, location and size; science programs within and surrounding urban, industrial and agricultural water and water transfer; science sewage management, recycling, clean, re-use; timely predict the distribution network, water, health water pressure, according to the requirements of various infrastructure maintenance, repair and construction.
The second step to strengthen the response to emergencies, including early warning and forecasting
It refers to the crisis early warning and advance warning of risk management, such as heavy rains flood warning. Predict the impact of the event is estimated to emphasize and rapid response. To water pollution, for example, once the pollution incident occurs, city emergency department with real-time data, determine contaminated sites, contaminated substances, the diffusion rate analysis over time to what extent the impact of the sewage generated in the downstream, to take urgent pollution treatment program and coordinate municipal departments or commercial, industrial, agricultural sector, to solve the problem within the planned time, coordination Sewerage company restorative assistance and guidance to affected areas and industrial and commercial, agricultural processor with the right to deal with the problem, to resume production.
The third step is to build smarter systems mathematical modeling, floor eco-city construction
Fragmented data can provide information to decision-makers is limited, it is necessary to expand the extension by one or several data platform interoperability and multi-dimensional mathematical model analysis. In addition to information on river water quality itself, all relevant departments on water resource management chain must resort to a lot of other information, refer to large amounts of data, analysis and decision making behind the data for insights relevance it may bring greater value. For example: information geographic information, the distribution companies along the river, plant information, weather.
The base layer including system hardware and software equipment needed for the construction, is the basis of system construction, including operating systems, database management systems, GIS platforms, and network monitoring equipment, servers and other hardware and software facilities.
