(Photo courtesy of JICA) HCM City (VNA) – TheJapanese Government will provide a non-refundable aid worth 1.88 billion JPY (16.84million USD) for Ho Chi Minh City to upgrade its existing seweragesystem using trenchless technologies.
Trenchless technologies such asboring tunnels and using drive and receptor shafts will add 50 years to thelife of the network. It will improve the drainage capacity and load-bearingcapacity through the upgrade of ageing drainage and sewer pipes.
Under an agreement signed inHCM City this week, the project will take 24 months starting next year, and thework will be done by Japanese companies.
HCM City’s rapid urban growth requiresurgent development of environmental infrastructure in tandem with meeting thedemands of safe water supply and water environment protection, according to theJapan International Cooperation Agency (JICA).
The city has made great effortsto build a new sewerage system, including building waste water treatment plantsand laying pipes, to improve the water environment, but the work ofrehabilitating old sewer pipes laid during French colonial times remains agreat challenge, especially in the downtown Districts 1 and 3.
In 2015,JICA funded a project carried out by the Osaka city Department ofConstruction and Sekisui Chemical to upgrade pipes under the Cong Quynh – NguyenCu Trinh roundabout in District 1 using trenchless technologies.
It proved to be efficient sinceit did not disturb day-to-day activities or the road surface in thetraffic-heavy districts.
Of the city’s 2,600km sewersystem, 932 kilometres of old pipes need constant upgrades. There are some100km of concrete sewers built during the French era, which are also in urgentneed of replacement to prevent flooding.
By reducing the need to dig upthe entire length of the sewer, the project will cause fewer road closures anddisturbances to the public.
JICA has been helping HCM City improve itswastewater system since 1999 starting with the implementation of a sewage anddrainage master plan.
Based on the master plan, the first phase ofthe HCM City Water Environment Improvement Project in Tau Hu – Ben Nghe riverbasins was carried out in 2017, with a wastewater treatment plant with a dailycapacity of 141,000 cubic metres being built and drainage capacity improved inthe Tau Hu – Ben Nghe canals, and new interceptors and sewer pipes beinginstalled.
The second phase of the project is scheduledto be completed in 2022, with a new wastewater treatment plant with a dailycapacity of 330,000 cubic metres being built and interceptors and sewer pipesbeing laid in the Đoi-Te river basin.
In the second phase, pipe-jacking technologywill be used for interceptor construction to minimise traffic interruption inthe busy districts 4, 5, 6, 8, and 10./.
