- The planning area includes waste water drainage basins to the wastewater treatment stations in the Northeast, in the West of Vinh Yen, in the center of Vinh Yen and in the South of Vinh Yen. The wastewater drainage system is divided into 04 basins:

+ Basin 1: Wastewater is collected to the D200-D400 system and then to the North-eastern treatment station of Vinh Yen.

+ Basin 2: Wastewater is collected to the D200-D400 system and then to the West Vinh Yen treatment station.

+ Basin 3: Waste water is collected to D200-D400 system and then to Vinh Yen Central treatment station.

+ Basin 4: Wastewater is collected to D200-D400 system and then to Nam Vinh Yen treatment station.

- Along the wastewater lines, manholes are arranged at the location of changing sluice cross-sections, redirecting sluices, at discharge points of works for dredging, periodic maintenance and repair of sluices.

b) Environmental sanitation:

- Domestic waste is collected by trolley at fixed hours or collected into garbage bins and sealed containers with a capacity of 0.4-1m3. The number and location of garbage containers and containers are calculated according to a service radius of about 100m and by the public service unit with the function of transporting to the City's treatment area.

- For the construction area of high-rise buildings, waste is collected from above to the garbage tank of each unit.

- At the green areas and main roads, small trash cans are put with a distance of 100m/can.

- Set up public toilets in green areas and parks. Wastewater of public toilets is collected by separate sewage drainage system and the waste must be treated on site up to environmental sanitation standards according to regulations on solid waste management.

c) Cemetery:

- The demand for burial and gathering of graves in construction investment projects in the planning study area shall be arranged in the concentrated cemeteries of each locality (district and city level).

- Existing cemeteries need to build fences and plant isolated trees so as not to affect the landscape and environment of the area.

3.3.7. Assessment and mitigation of environmental pollution impacts:

- Construction investment projects need to make environmental impact assessment according to the provisions of law.

- During the construction process, it is necessary to have solutions to minimize pollution caused by dust, exhaust gas, noise, vibration, wastewater, sediment and domestic waste generated on the construction site.

- Projects when put into use need to regularly ensure environmental conditions; be monitored, inspected - examined, and immediately handled factors that have negative impacts on the environment according to regulations.
