9.2. Technical preparation orientation
a) Select the minimum controlled construction elevation
Based on the terrain, water level warning levels of rivers affecting the research area, current construction elevation in the area and actual investigation, select the control construction elevation as follows:
- For existing towns and villages: Keep the existing foundation. It is recommended that if the existing foundation is < alarm level III, when possible, the foundation should be raised to > MN(III) + 0.3m.
- For newly planned construction areas:
Flood affected area:
+ Minimum controlled ground elevation for civil use = MN (III) + 0.3m.
+ For newly built public works (municipalities, schools, power stations...): minimum controlled ground elevation = MN (III) + (0.7-1.0)m.
+ For planned industrial zones: Minimum controlled ground elevation = MN (III) + (1.0-1.5)m.
+ For district roads, if any road has elevation < MN (III), there should be a project to upgrade to > MN (III) + (0.5 + 0.7) m.
Note: MN(III) is the water level of level III alarm. Because the rivers have large slopes, the water level at each location will be different.
b) Source of fill soil: Fill soil can be exploited from dredging streams or from leveled soil. However, when exploiting fill soil, it is necessary to reach an agreement with the Department of Natural Resources and Environment and local authorities.
c) Foundation and drainage work for renovated and newly built areas (towns):
In the new construction area, the selected elevation is in harmony with the existing elevation of the stable construction, ensuring quick drainage to avoid local flooding in the surrounding area.
- Zone 1: Boundary includes 3 communes and 1 town: Luong Bang town, Nhan La commune, Vu Xa, Hiep Cuong.

- Orientation of water supply pipeline network
Network organization: The general structure of the pipeline network is divided into 3 levels: Transmission, distribution and service. Organized according to the detailed traffic and land use planning until 2035 to estimate connection points, diameters and lengths of transmission and distribution pipelines. At the connection points of distribution pipes to the transmission network, valves, electromagnetic flow meters and data transmission networks are installed.
Calculate the network according to the day of maximum water use and fire during the hour of maximum water use, calculate the network planning according to 2 phases 2025 and 2035. Ensure continuous and stable water supply for the district 24/24 hours a day.
The minimum calculated network pressure is 12m in the most unfavorable areas. Buildings with more than 3 floors must have a local booster pump station.
- Protect water resources.
Protect groundwater from surface water pollution.
Protect surface water sources from human activities and especially from waste, wastewater from concentrated livestock areas, industrial zones and chemicals from agricultural production activities.
Protect and maintain the quantity of surface water resources from being degraded and exhausted: Maintain environmental flows on rivers with the participation of reservoirs in regulating. Improve the water storage and supply capacity of reservoirs, especially water storages.
Protecting the water quality of surface water sources: treating wastewater to meet environmental standards before discharging into rivers. At the same time, maintaining environmental flow reserves to protect aquatic ecosystems in rivers.
Surface water source protection area: Around the water intake point for the water supply system, a sanitary protection area must be maintained: Within 200m from the water intake point upstream and 100m downstream, no construction works that pollute water sources are allowed (no discharge of wastewater, agricultural water, livestock, bathing).
Water plant and water supply station protection area: Within 30m from the foot of the wall of the treatment works, a protective fence must be built around the station area. Inside this fence, no houses, entertainment, living or sanitation facilities may be built.
The minimum water supply pipeline protection area is 0.5m.
9.4. Power supply infrastructure orientation
a) Power source
- Power source for Region 1: Currently, the power source from Kim Dong 110KV Station (2x25MW) will still be used; By 2020, according to Hung Yen Province's power planning, the Kim Dong 2 110/22KV transformer station (2x25MW) will be built, which will be the main source for Region 1 in the future.
- Power supply for Zone 2: Powered from Kim Dong 110KV Station (2x25MW).
- Power source for Region 3: Currently, the power source from Kim Dong 110Kv Station (2x25MW) will still be used; by 2030, according to Hung Yen Province's power planning, the Kim Dong 3 110/22kv transformer station (2x25MW) will be built. This will be the main source for Region 3 in the future.
b) Power grid
- 220KV grid: Double-circuit 220KV line from Kim Dong 220/110KV station to Pho Cao 110KV station with a line length through the district of about 9km;
- 110KV grid: 110KV line, Kim Dong - Pho Cao branch, goes to 110kV Thanh Pho station with a line length through the district of about 1km.
- 110KV line branching from Thuong Tin - Kim Dong - Kim Dong 3 Station to the City with a length of about 6.4km passing through the research boundary.
The entire 220Kv and 110Kv high voltage power grid running through the district must absolutely ensure the safety corridor of the National power grid according to regulations of the electricity industry.
- 22KV grid:
For urban centers and new urban areas, most of the medium voltage grid has been renovated and converted to 22KV voltage level. Newly built medium voltage lines are designed according to the following standards:
+ Design of loop circuits, open operation ensures flexible and continuous power supply, convenient for operation and closing, disconnecting, and protection. 100% backup.
+ This ring network can be supplied with power from 2 110kV transformer stations or from 2 busbars of a 110kV station with 2 transformers. To ensure the development reserve and reserve power supply for loads of other lines in case of incidents, the medium voltage main lines in normal mode are only designed to carry a load of 60 - 75%. Thus, each output line carries a load of no more than 8MW.
+ For central areas and new urban areas with stable planning, it is recommended to use waterproof XLPE underground cables with a general cross-section of ≥ 240mm 2 and make transitional connections.
+ For existing urban areas and residential areas, uninsulated power lines will be used - main line cross-section from 185mm 2 to 240mm 2 , branch lines from 95mm 2 to 120mm 2 to meet electricity needs.
+ Standards for medium voltage grid voltage loss: Medium voltage loop lines, open operation are designed so that the voltage loss at the farthest household does not exceed 5% in normal operating mode and does not exceed 10% in post-fault mode. For radial medium voltage lines, the voltage loss at the end of the line is ≤ 5%.
+ Research on the construction of technical trenches to combine underground medium voltage grids on newly constructed or expanded traffic routes.
- Distribution transformer station: There are 3 types of stations to be implemented:
+ Single-pole station: This is a newly designed station that solves the problem of saving land, urban aesthetics and undergrounding the power grid. This type of station is used to renovate suspended stations that do not ensure urban aesthetics and safe power supply.
+ Built-in station (indoor station): This type of station occupies a large construction area of 20-30m2, however, this type of station is very suitable for underground grid development, minimizing the effects of transformers and switching devices on the general aesthetics and safety of power supply.
+ Suspension station: (Limited development)
Regarding connection structure: For underground medium voltage grid areas, transformer stations make transition connections to be able to operate from both sides. For areas where overhead lines still exist, transformer stations make branch connections on the lines.
New urban areas or new residential areas: Using construction stations, project management boards must arrange land in new urban areas to place stations, medium and low voltage lines must use underground cables to ensure urban aesthetics.
Residential areas are relatively stable: Use pole type stations. Suspended transformer stations when renovated to replace machines or increase capacity can be converted to pole type structures.
- Low voltage grid: It is expected that in the central area and new urban areas, the low voltage grid will continue to be underground. The residential area in the current state is expected to be renovated and upgraded, using exposed ABC cables.
- Lighting grid:
The lighting system must be built based on the general planning solution for the research area. The lighting design and selection of lighting equipment are suitable for the urban architectural landscape. In the central area of the city, towns and main streets, the lighting grid is expected to be arranged underground, the village roads and branch roads are renovated and upgraded, using exposed cables on the same poles as the low-voltage grid.
9.5. Orientation of telecommunications and postal infrastructure
a) Transmission network: Planning for new development of optical transmission lines according to criteria.
- Developing new transmission lines to industrial parks, industrial clusters, new urban areas...
- Developing transmission lines on new routes, trunk routes...
- Develop transmission lines to serve newly installed multi-service switching nodes.
- Developing transmission lines to tourist areas, service areas... to serve the needs of entertainment, commerce, tourism...
- Develop transmission lines to areas with high traffic and high demand.
- Develop Ring transmission lines between districts, ensuring information security.
- Increase TVT subscribers
b) Peripheral network: Deploy construction of underground cable sewer infrastructure and peripheral cable network in the area, with priority given to the following areas:
- Town People's Committee area; urban core area; tourist area, area with high aesthetic requirements. Undergrounding cable TV cable network synchronized with the undergrounding of telecommunication cable network. The undergrounding process is implemented synchronously with the construction of infrastructure of sectors (transportation, urban, construction...) in each area. Undergrounding in the direction of sharing infrastructure among enterprises.
- In areas that do not meet the conditions for undergrounding, renovate the peripheral cable network infrastructure (tie the cable system...) to ensure urban aesthetics. In areas where new peripheral cable network infrastructure is being built (residential areas, new urban areas, newly built roads...), bury the entire peripheral cable network infrastructure to subscribers and subscriber clusters. In areas where peripheral cable networks have been built before: Underground the peripheral cable network to the cable cabinet system on roads, streets, and residential areas (underground to subscribers in central areas, areas with high aesthetic requirements), renovate the peripheral cable network system to ensure urban aesthetics.
- Current residential areas: Renovate the peripheral cable network, shorten the service cable distance, bury the peripheral cable network on main transmission lines, trunk lines, and areas with high aesthetic requirements. Make a plan for burying and renovating the peripheral cable network infrastructure in each specific phase and publicly announce it as a basis for businesses to implement.
c) Wireless telecommunications network: Developing mobile information network antenna tower infrastructure in the province applying new, advanced and modern technologies (4G technology, broadband access technology...). Developing the infrastructure of the antenna tower system to receive and transmit signals in the direction of applying new technologies. Developing the antenna tower system to receive and transmit signals using multi-frequency technology. Strongly developing the infrastructure of camouflaged antenna towers to receive and transmit signals.
9.6. Orientation of drainage, solid waste management and cemetery
a) Wastewater drainage:
- Choosing a drainage system:
+ Urban areas:
Newly developed areas without drainage systems use completely separate wastewater drainage systems and centralized wastewater treatment.
In areas where projects have been established, wastewater collection and treatment systems are implemented according to separate projects.
For areas with a common drainage system, build a sewer system, a water separation well to collect wastewater to the treatment plant combined with upgrading and renovating the pipeline.
+ Existing village area: 100% of households must use sanitary toilets, encouraged to use standard septic tanks.
+ Rural residential areas with small and scattered water volumes: build covered ditches, drain water together with rainwater, utilize the system of canals and ditches in the fields; existing ponds and lakes in the fields for biological treatment under natural conditions. Reuse treated wastewater for agricultural purposes.
+ Groups of households raising livestock, poultry and concentrated livestock farms will build biogas tanks, treat waste and collect gas for daily use.
+ Tourist area: Prioritize local wastewater treatment for each project or group of projects using advanced tanks such as improved septic tanks (BASTAF-F), anaerobic filter tanks with floating material layer, anaerobic sludge blanket reverse osmosis tanks (UASB) or modern technology-based block-type biological treatment facilities (JRY) with high efficiency and low space consumption. Wastewater after these tanks will be thoroughly treated by a trench filtration system or reused for watering plants, washing roads, etc.
- Drainage solution:
+ Wastewater drainage system has diameter D300÷D750mm, made of reinforced concrete, minimum slope imin = 1/D.
+ Minimum sewer burial depth is 1m; maximum is 5m to the bottom of the sewer. At locations with sewer burial depth >5m, pump stations are installed to raise the elevation.
+ Pressure sewer line uses galvanized steel pipe, pressure sewer line arranges 2 parallel pipes to ensure safety in operation in case of incident. Pressure pipeline is buried 1m deep.
+ The transfer pumping station uses a wet submersible pump, the station building is built underground and can be combined with a manhole to save land and ensure aesthetics.
- Build 08 wastewater treatment stations to treat wastewater for the entire Kim Dong District.
b) Solid waste (CTR)
Solid waste is collected centrally: Collection vehicles follow a set schedule, stopping at intersections, households bring their solid waste to dump into the vehicles; then motor vehicles come to collect and transport it away. In small alleys and narrow roads, small handcarts can be used for collection, then gathered at a common point, for motor vehicles to transport to the treatment facility.
Improve transportation capacity to make it convenient, fast, hygienic and economical; gradually mechanize transportation and loading and unloading to the highest level to limit adverse impacts on the environment.
c) Cemetery
Do not build cemeteries in urban development areas.
Continue to use centralized cemeteries that ensure environmental sanitation requirements in communes and towns that have been approved for planning and renovated into park cemeteries.
Existing cemeteries do not meet environmental hygiene requirements, burial activities must be stopped, trees must be planted to isolate. People are encouraged to use cremation.
