b) Investment capital sources:
- State budget capital;
- ODA capital, foreign aid capital;
- Investment credit capital;
- Domestic commercial loans;
- Capital from domestic and foreign investors;
- And other lawful capital sources.
9. Strategic environmental assessment
a) Forecast of environmental impacts and changes upon implementing the master plan:
- Exploitation of surface water source of Red and Duong rivers: because they are two rivers with complicated hydrological regimes and flows, the exploitation of their water sources may affect the flow regimes and cause dyke erosion.
- Exploitation of groundwater sources will affect geological elements, and the water quality will be unsatisfactory.
- The construction of concentrated water plants, booster pump stations and transmission pipelines will affect the environment, air, noise, traffic, and so on.
- When water plants operate, they will generate wastes of the water treatment process, which cause environmental pollution.
b) Solutions to minimize environmental impacts
Water source exploitation and use:
- Surface water sources:
+ To study and assess the negative impacts on the flows and hydrological regimes, to formulate the process on water source quality and deposit control and monitoring and response plans aiming to ensure water supply safety.
+ To strictly control sources causing pollution in the river basins such as sewage, waste discharged from urban areas, industrial parks and agricultural production.
- Groundwater sources:
+ To assess and explore precisely the quality and reserves of groundwater in the area; to formulate plans for groundwater exploitation and protection.
+ To study, assess and strictly control the decrease of the groundwater level, the quality of groundwater and extent of ground subsidence relating to groundwater exploitation in the area.
Control of construction activities
- Appropriate design solutions and technologies must satisfy for ecological environment and water source protection. Concurrently, restrict to the utmost the ground clearance and resettlement.
- In the construction stage:
+ To formulate appropriate construction measures, and solutions to minimize impacts to environment.
+ Measures to process the air, waste and noise pollution applicable to vehicles and construction machines at construction sites and along the roads of transportation.
+ Measures to prevent incidents during construction.
- In the operation management stage:
+ To improve the water plant management and operation capacities of water supply units, ensure industrial sanitation and external sanitation environment of water plants; water used during the treatment process should be researched for recovery and re-use and sediments and wastes must be treated up to the prescribed environmental technical regulations.
+ To formulate and carry out plan on safe water supply.
+ To formulate processes on prevention, detection and handling of incidents of clean water supply systems.
- Other support measures.
