2. Planning viewpoint

Being consistent with the master plan of socio-economic development, land use planning, construction planning of provinces of Cau river basin; the Overall Scheme of protection and sustainable development of ecological environment and landscape of Cau river basin that have been approved by the Prime Minister under the decision No. 174/2006/QD-TTg dated July 28, 2006 of the Prime Minister; orienting the development of water drainage of urban areas and industrial parks in Vietnam by 2025 and vision to 2050 under the Decision No. 1930/QD-TTg dated November 20, 2009 of the Prime Minister; the water drainage planning of 3 key economic regions in the North, Central and South by 2020 under the Decision No. 1336/QD-TTg dated September 22, 2008 of the Prime Minister and the other specialized planning that have been approved by the competent authorities .

The planning of water drainage and waste water treatment system for residential areas and industrial parks ensures the stable and sustainable development on the basis of synchronous construction of system of rainwater drainage and wastewater from collection and move for treatment for each basin and in accordance with the conditions for social and economic development;

Using technology and wastewater treatment equipment must meet the requirements, standards and technical regulations for wastewater treatment in accordance with the specific conditions of each locality; priority is given to the application of modern and energy-saving technology and equipment taking into account the possible upgrade in the future.

Encouraging domestic economic sectors to participate in construction investment and management of water drainage system;

3. Planning objective

Concretizing the Overall Scheme of protection and sustainable development of ecological environment and landscape of Cau river basin which has been approved by the Prime Minister under the Decision No. 174/2006/QD-TTg dated July 28, 2006;

...

...

...

Meeting the state management requirements on drainage and wastewater treatment. Being the grounds for formulation and implementation of construction investment projects of drainage and wastewater treatment system within Cau river basin;

4. Planning content

a) Area drainage planning

- Calculation indicators:

+ Drainage indicators for special urban areas and concentrated industrial parks: 15 ÷ 20 l/s.ha.

+ Drainage indicators for urban areas (from type V to I): 12 ÷15 l/s.ha.

+ Drainage indicators for urban residential areas: 8 ÷10 l/s.ha.

- Area drainage planning:

+ Cau river basin is divided into 15 drainage areas, including:

...

...

...

. 11 drainage areas combining self-drainage and dynamic drainage for a number of regions with topography lower than the river level during flood season;

+ Solution to water drainage for areas is to store water by the regulating lake or landscape lake system in the basin, enhancing mode of self-flowing drainage, reducing costs of investment and management of head works of dynamic drainage, improving ecological environment and building up urban landscape;

+ The permeable natural surface is controlled in the beginning; limiting the conversion of existing water surface to other purposes of use. Minimize the flooding in the urbanization process, under the impact of climate change, the minimum area of water surface F ≥ 5% of the area of basin to be drained;

b) Rainwater drainage planning

- Urban area:

+ The urban areas are divided into water drainage basins to ensure rapid and thorough drainage of rainwater;

+ Building new reservoirs, drainage pumping station and upgrading main drainage axis.

+ Old urban areas: Improving and upgrading the existing drainage system for rainwater drainage (combining the solution to construction of culvert and separating well to move the wastewater to the treatment plant);

New urban areas: Built with separate drainage system. Rain water is discharged into rivers, canals without treatment;
