Measures to solve the shortage of water resources in Tianjin

First, adhere to total amount control and optimize water use, and the pattern of optimal allocation of multiple water sources has initially taken shape. First, strict planning and management, control the total. The Municipal Water Affairs Bureau issued the total water consumption index and the total groundwater exploitation index of each water-using area. At the same time, in conjunction with the Municipal Development and Reform Commission, the annual plan for non-domestic water use and water saving in the city will be compressed to 2 1 administrative region and 48 industries respectively, and the progressive price increase system for over-planned water use will be strictly implemented to control the total water consumption. Second, strict water resources demonstration system and good resource allocation. Adhere to the optimization of water use, low water use, water resources demonstration extends from construction projects to planning and industrial parks, and the water resources demonstration rate of municipal construction projects is 100%. The policy of using reclaimed water and seawater shall be implemented for all newly rebuilt and expanded thermal power plant projects, and all projects with the conditions of using reclaimed water, seawater and rainwater will not be approved for conventional water use. The third is to strictly manage the water intake permit and close the terminal water. Revise and implement the water law, bring geothermal and mineral water into the management of water intake permit, realize the full-caliber management of water intake permit, and reduce the annual groundwater intake100000 cubic meters. Second, adhering to service development, multi-channel open source and rational development and utilization of limited water resources are the "lifelines" of Tianjin. However, in recent years, the inflow of Panjiakou Reservoir has been continuously dry, which can no longer meet the water demand. In order to ensure economic and social development, first, give full play to the maximum benefit of water diversion from Luanhe River, on the basis of ensuring the water safety in the central city, make great efforts to serve the development and opening up of Binhai New Area, and build a number of water supply projects such as the second Luanhe River Diversion Pipeline and Sino-Singapore Eco-city. Second, accelerate the development and utilization of unconventional water, and build seven reclaimed water plants with a daily treatment capacity of 2 1 10,000 cubic meters, with the reclaimed water reuse rate reaching more than 20%; A number of seawater desalination projects such as the first phase of Beijiang Power Plant have been completed one after another, with a daily desalination scale of 220,000 cubic meters; Construction of urban and rural rainwater allocation projects, in 2009, the utilization of rainwater resources was nearly 200 million cubic meters. The third is to implement emergency water diversion from the Yellow River to Tianjin. With the strong support of the Ministry of Water Resources and Shandong and Hebei provinces, the emergency water transfer from the Yellow River to Tianjin was successfully implemented. At the same time, the second yellow river diversion pipeline and the project of diverting yellow river into Binhai New Area are carefully planned and constructed to expand the water supply scope of diverting yellow river. Fourth, speed up the construction of the South-to-North Water Transfer Project, simultaneously promote the construction of Tianjin trunk line and supporting projects in the city, and strive for the early completion of the South-to-North Water Transfer Project. Third, adhere to comprehensive conservation and scientific management, and significantly improve the efficiency of water resources utilization. First, adjust the industrial structure to promote water saving, prohibit high-water consumption projects, and develop high-end and high-quality water-saving industries. At present, the eight dominant industries such as aerospace and electronic information in our city account for more than 90% of the industry. The newly added water consumption per 10,000 yuan of industrial added value in the city has dropped to about 10 cubic meter, and the reuse rate of industrial water has exceeded 94%. Second, system reform promotes water conservation. On May 7, 2009, Tianjin Water Affairs Bureau was formally established, which realized the unified management of water-related affairs such as water diversion and supply, water saving, sewage treatment and reclaimed water reuse, and effectively promoted the in-depth development of water saving work. At the same time, straighten out the district and county water system and truly realize the integrated management of water affairs in the city. The third is to formulate policies and regulations to strengthen water resources protection. Our city has promulgated and implemented the first local water-saving regulation in China, and issued many policies and regulations such as "Regulations on the Management of Urban Drainage and Reclaimed Water Utilization". Fourth, use economic leverage to promote water conservation. Since 1996, the water price has been adjusted nine times, and the domestic water consumption of residents has increased from 0.68 yuan per ton to 3.9 yuan, and the non-resident water consumption has increased from 0.95 yuan to 6.7 yuan. Fifth, typical demonstration encourages water conservation. Our city invests more than 20 million yuan every year to support industrial water-saving technological transformation, 262 units are named as water-saving enterprises by the municipal government, intelligent water-saving IC cards are fully promoted in colleges and universities, the largest water-saving science and technology exhibition hall in the north is built, and the 55-square-kilometer water resources comprehensive utilization demonstration zone in the airport logistics processing zone is fully launched. Fourth, adhere to the principle of treating both the symptoms and root causes and comprehensive management, and continuously increase the protection of water resources. First, protect drinking water sources. Every year, our city arranges 20 million yuan for water source protection in the upper reaches of Luanhe River, completes the protection plan of Yuqiao Reservoir, starts the resettlement project, and strives to resettle all the 654.38+10,000 immigrants in the reservoir area to demonstration towns. The second is to implement pollution interception and pollution control projects. Since the project started in 2008, 365,438+0 sewage treatment plants have been built and renovated, and 29 sewage treatment plants are under construction. All the effluent reached the first-class standard, and the advanced treatment and reuse of sewage were strengthened for domestic miscellaneous use and improving the ecological environment. The third is to strengthen the operation management of sewage treatment plants and reclaimed water plants, supervise and assess the quality of effluent, and strictly control the discharge of excessive sewage. Fourth, strengthen land subsidence control, strictly implement the one-vote veto system to control subsidence, and promote the conversion of underground water sources. In 2009, the groundwater level in most over-exploited areas began to rise, the area of settlement funnels at all levels decreased by about 30%, and the settlement funnels with annual settlement greater than 30 mm in the central city basically disappeared.
