c/ Forecast of water drainage needs in the Mekong River delta key economic region:

- Forecast of the total volume of wastewater in urban areas:

- Forecast of the total volume of wastewater in industrial parks:

+ By 2015, the occupied area will be around 4.180 ha and the volume of industrial wastewater will be 102,500 m3/day.

+ By 2020, the occupied area will be around 15,343 ha and the volume of industrial wastewater will be 369,000 m3/day.

- Forecast of the total volume of wastewater in rural residential areas:

Forecast of the total volume of wastewater in the Mekong River delta key economic region:

d/ Master plan on water drainage in the Mekong River delta key economic region:

- Basins and water drainage directions in the region:

+ In Can Tho city and An Giang province, water will be drained mainly into Hau river.

+ In Ca Mau and Kien Giang provinces, water will be drained into rivers in the region and into the sea.

- Rainwater drainage plan:

+ Orientations for rainwater drainage in urban areas by 2015:

For new urban areas: To build separate water drainage systems; untreated rainwater will be drained into rivers and canals.

For old urban areas: To upgrade the common water drainage system with surrounding sluices and current-separation pits to collect wastewater for wastewater treatment plants.

For urban areas without water drainage projects, to study and adopt solutions in line with the general plan on construction of the Mekong River delta.

+ Orientations for rainwater drainage in urban areas through 2020:

To concentrate on improving water drainage systems; to further upgrade and maintain water drainage systems to completely eliminate local inundation caused by rain.

- Wastewater drainage plan:

+ Urban areas:

. For urban centers of grade m or higher grade currently using the common water drainage system, to build sluices and separation wells to carry wastewater to treatment plants.

. For urban centers of grades IV and V and industrial parks, to build separate water drainage systems.

+ Rural areas:

In residential clusters, due to small volumes of wastewater and depending on terrain conditions, to build bio-reservoirs for wastewater treatment.

In residential lines, wastewater discharged by each household or group of households shall be treated (septic tanks or biogas cellars) and drained into canals or sluices.

To control water quality in aquaculture areas and limit the use of insecticides and chemical fertilizers in agriculture.

- Plan on building of wastewater treatment plants:

+ Wastewater from urban areas, townships and industrial parks within the Mekong River delta key economic region shall be conducted to wastewater treatment plants and then drained into rivers in the region and into the sea.

+ For urban centers of grade IV or higher grade, to build complete daily-life wastewater drainage systems from collection sluices to wastewater treatment plants. Depending on terrain conditions and wastewater collection capacity of each urban center, to build an appropriate number of treatment plants. The designed capacity of a wastewater treatment plant shall be calculated based on people's access to water drainage services and on each development period.

+ For urban grade-V centers, to evaluate and select the order of priority for building daily-life wastewater drainage systems based on the level of pollution.

+ For industrial parks, to build separate wastewater drainage systems so that by 2015 they will be able to treat all industrial wastewater.

Daily-life and industrial wastewater treatment plants are expected to be built in provincial centers of the Mekong River delta key economic region as follows:

+ Number of daily-life wastewater treatment plants: 13.

+ Number of industrial wastewater treatment plants: 14 by 2015 and 17 by 2020.

5. Investment phasing:

- Period up to 2015:

+ To review and adjust water drainage plans and projects in the region's provinces in conformity with this master plan.

+ To concentrate investment in building wastewater collection systems and wastewater treatment plants for urban centers of grade IV or higher grade.

+ To build wastewater treatment plants for industrial parks, ensuring that industrial wastewater is treated according to regulations before being discharged into the environment.

- During 2015-2020:

+ To build complete rainwater drainage systems in combination with further renovating and maintaining water drainage systems in urban areas to ensure stable and sustainable water drainage and eliminate inundation caused by rain.

+ To build complete wastewater collection systems and wastewater treatment plants for urban centers of grade IV or higher grade and industrial parks.

+ To formulate projects and build wastewater collection systems and wastewater treatment plants for grade-V urban centers.

6. Investment capital sources:

- State budget;

- ODA and foreign aid;

- Investment credit;

- Domestic and foreign investors;

- Capital raised from other economic sectors.

7. Strategic environmental assessment:

- Forecast of environmental impacts caused by the implementation of the master plan:

+ The construction of wastewater treatment plants and pipelines may cause traffic congestion, noise and environmental pollution in the region, especially along national highways.

+ During management and operation:

. Incidents may occur in the collection of wastewater to treatment plants, thus causing environmental pollution in the region (choked or broken water drainage pipelines, or breakdown of wastewater pump station failures).

. Waste (mud and deposited substances from treatment plants or water drainage pipelines) may pollute the environment.

. Before being discharged into water drainage sluices, the volume of wastewater from service and production establishments may exceed the allowable limit, affecting the quality of treated wastewater.

• The quality of treated wastewater is poor, directly affecting the environment of surface water currents.

- Measures to mitigate environmental impacts:

+ During construction:

. To adopt appropriate construction methods and solutions to minimizing environmental impacts.

. To take measures to treat environmental and air pollution and noise caused by vehicles and construction machines at construction sites and along routes of transportation.

. To take measures to prevent incidents.

+ During management and operation:

. To increase the capacity to manage and operate wastewater drainage systems and wastewater treatment plants.

. To take measures to maintain and dredge water drainage sluices.

. To elaborate and observe regulations on collection and treatment of waste from wastewater treatment plants and water drainage systems.

. To work out solutions to reducing environmental pollution upon the occurrence of incidents in water collection systems.

. To take measures to supervise and inspect the quality of wastewater before and after treatment; to adopt solutions to redressing incidents to ensure water quality up to standards or technical regulations.

+ Other supporting measures.
