Planning viewpoints To conform with the socio-economic development master plan; the land use master plan; the general plan on constmction of Hanoi Capital through 2030 with a vision toward 2050; the water drainage master plan for three n01them, central and southern key economic regions; the olientations for water drainage development in urban areas and indust1ial parks through 2030 with a vision toward 2050; and other relevant approved specialized master plans; To take into account the impacts of climate change, directing toward stable and sustainable development, based on the building of synchrnnous rainwater and wastewater drainage systems from collection to treatment for eve1y urban basin to suit socio-economic development conditions. For rainwater drainage planning, to apply the technical model of sustainable water drainage, enhancing the rainwater absorption and storage capability, contiibuting to the minimization and incremental elimination of urban flooding in the central Hanoi Capital and other urban centers within the scope of planning. To concentrate on the concentrated wastewater drainage and treatment systems for urban centers (especially the central one); to orientate the water drainage for small urban centers, outlying and suburban areas, industiial parks and hospitals, with a view to improving hygiene and protecting the environment, meeting the socio-economic development requirements. To encourage various economic sectors to invest in the constmction of Hanoi Capital's water drainage systems. 3. Planning objectives 25 To concretize the orientations fo r development of Hanoi Capital's water drainage in the general plan on consti·uction of Hanoi Capital through 2030 with a vision toward 2050, already approved by the P1ime Minister. To detennine water drainage zones and basins. To forecast the rainwater drainage requirements and total urban wastewater volume; to dete1mine schemes on water drainage and wastewater ti·eatlnent for each urban basin. To step by step address urban flooding based on rainwater volumes projected for a 10-year cycle for key works while being able to regulate floods with sho1ter-te1m cycles. The rate of population provided with wastewater collection and treatment services in the planning scope will reach 9 0% by 2030 and 100% by 2050. To identify the demand for investment in water drainage systems in each peliod, se1ving as a basis for fo1mulation and implementation of water drainage projects in Hanoi Capital and meeting the requirements of state management of water drainage. 4. Planning contents a/ Flood drainage and water drainage zoning The drainage of floods in Hanoi must comply with the master plan on Red river-Thai Binh river flood prevention and control in the Prime Minister's Decision No. 92/2007/QD­ TTg ofJune21, 2007, and Hanoi city's detailed master plan on flood prevention and conti·ol.
