The project costs VND 115.7 billion in total. Of this figure, VND35.4 billion is allocated for compensation and resettlement work, and the remaining VND 65.67 billion for the construction work.
It soon-to-be-built drainage canal borders a planning road in the Hoa Nhon resettlement area to the north, hills and mountains to the east and the west, and the Tuyen Son - Tuy Loan riverside road to the south.
The intention of the project is to solve the drainage of treated rainwater and wastewater that meets technical standards and regulations in accordance with the law on environment at the Hoa Nhon Industrial Park, the Hoa Cam Industrial Park on second stage, a residential area serving the clearance of the Hoa Nhon Industrial Park, an existing residential area north of the national highway 14B, and existing residential areas adjacent to the canal.
The project will cover an area of 76,522m2. Of this, 42,112m2 will be earmarked for the construction of the drainage canal, and 34,410m2 for the development of technical infrastructure.
The first point of the drainage canal connects with the canal section of the Hoa Nhon resettlement area (through Km23+100 on National Highway 14B), cuts through the area of cultivated rice fields and people's gardens and hill areas and then pours into a section of the Tuy Loan River flowing through Hoa Nhon Commune.
Under the project, the canal bed will be reinforced with concrete panels, and culverts will be constructed at the intersections of between the canal and the existing roads. Along the canal, railings and handrails will be built to ensure the safety of animals and people.
Reinforced concrete railings are 1.2m height, and handrails are made of galvanized steels D76.
Stairs will be arranged every 100m in order to serve the maintenance of the canal during the exploitation process.
According to statistics, 5 residential land plots have been acquired with an area of 3,557.7m2, and the land area associated with the permanently acquired architectural works is about 564m2 with 11 semi-permanent houses.
In the project area, there are some dirt roads with a width of about 2-3m. The project's drainage basin is expected to have an area of 403ha, limited by a section of National Highway 1A passing through Da Nang, National Highway 14B and the watersheds of Hoa Nhon and Hoa Tho Tay mountains.
Treated rainwater and wastewater will be discharged into the Tuy Loan River through the canal.
The design and construction of the project’s technical infrastructure works are expected to be implemented from January 2021 to June 2023, whilst the project's technical infrastructure will be developed from July 2023 to July 2025.
