b/ Northern key economic region water drainage planning

- Rain water drainage planning

+ Drainage basins and directions: There are six main water drainage basins:

• Day river basin, which embraces Hanoi city and the provinces of Ha Nam, Ninh Binh, Nam Dinh and partly Hoa Binh. This basin drains water mainly to Nhue and Day rivers. Particularly for Hanoi city, Set and Kim Nguu river basins drain water to Red river in the flood season through Yen So pump station;

• Cau river basin, North of Duong river, covering the provinces of Bac Ninh and Vinh Phuc, the districts of Gia Lam, Dong Anh and Soc Son of Hanoi, flowing to Cau river;

• Red river left basin in southern Duong river (covering the districts of Thuan Thanh, Luong Tai, Gia Binh of) Bac Ninh province, part of Hai Duong province and Hung Yen province, flowing to Red river;

• Thai Binh river downstream basin in Hai Duong province. Concretely, for Hai Duong city, rain water drains to Sat and Thai Binh rivers;

• Hai Phong city basin draining water to Lach Tray and Cam rivers:

• Ha Long city basin draining water to the sea.

...

...

...

• Nhue river system: Draining water for Hanoi city and Ha Nam province in 3 directions to Red river, Day river and Chau river. Major works: Yen So pump station draining water to Red river and three big pump stations draining water to Day river (Ngoai Do 2, Que 2 and Lac Trang 2 pump stations);

• Northern Duong river drainage system: Draining water for Bac Ninh and part of Hanoi, Vinh Phuc. Receiving drained water of this system are Cau, Ca Lo. Ngu Huyen Khe, Duong and Red rivers. For newly developed Dong Anh urban center, water will be drained to Red river through Vinh Thanh pump station;

• Bac Hung Hai drainage system: Draining water for Hung Yen and Hai Duong province and part of Bac Ninh province and Hanoi city.

- Waste water drainage planning

+ Waste water volume forecast

The waste water volume of centrally run cities, provincial towns, industrial parks in the region will approximate 2,030,000 m³/day, including:

• Daily-life waste water: Around.1,230,000 m³/day;

• Industrial waste water: Around 800,000 m³/day.

+ Waste water drainage systems

...

...

...

The urban water drainage and waste water treatment systems will be mainly built independently in each urban center in conformity with the regional urban development.

The regional connection of water drainage and waste water treatment systems of urban centers and industrial parks will be managed according to river basins, comprising 6 main ones: Nhue river basin, Cau river basin, Red river left basin. Thai Binh river basin. Lach Tray river basin, and Cam river and Quang Ninh sea area.

+ Waste water treatment technologies

Depending on specific conditions of each urban center, modern or simple waste water treatment technologies will be applied in conformity with the requirements of receptacle sources and local natural and socio-economic conditions.

c/ Central key economic region water drainage planning

- Rain water drainage planning

+ Drainage basins and directions:

For urban centers in the central key economic region: Water will be drained to principal rivers, with 6 main river basins:

• For Da Nang city, water will be drained to Han and Cu De rivers;

...

...

...

Huong and Bo rivers:

• For Tarn Ky city, water will be drained to Tarn Ky and Truong Giang rivers;

• For Quang Ngai city, water will be drained to Ve and Tra Khuc rivers;

• For Quy Nhon city, water will be drained to Con and Ha Thanh rivers.

+ Major systems and works

Provincial towns in the central key economic region lie in downstream areas or at river sections affected by sea tide. With the existing foundation elevation, the water drainage in urban centers during the dry season sees no problem. But in the flood season, a number of urban centers become flooded upon the occurrence of floods at 5% or even 10% frequency; hence, multi-purpose headwater facilities will be built for water supply to downstream areas, electricity generation and reduction of floods in river basins, including:

• On the O Lau river system: To build O Lau reservoir of 40 x 106 m³ capacity;

• On the Huong river system: To build flood - cutting reservoirs of Ta Trach. Binh Dien and Co Bi;

• On the Bu Lu river system: To build Thuy Yen reservoir in Thuy Cam with a 26 x 106 m³ capacity, supplying water for Chan May - Lang Co economic zone and cutting off floods for Thua Luu river;

...

...

...

Dakmi 1, Dakmi 4, Tranh river 1, Tranh river 2 and Khang river with a total useful capacity of 2,857 x 106 m³ and an anti-flood capacity of 1,187 x 106m³;

• On Tra Khuc river: To build Nuoc Trong reservoir to supply water for Dung Quat economic zone;

• On Con river: To build Dinh Binh reservoir, stage I, with a useful capacity of 200 x 106 m³ and an anti-flood capacity of 112 x 106 m³, supplying water for downstream areas and Quy Nhon city.
