Viet Nam: HCM City to install sensor chips at flooding hotspots
HCM CITY — Flood-sensor chips will be installed at an additional 32 flooding hotspots to warn HCM City residents of potential floods from heavy rains or tides, according to the HCM City Urban Drainage Company.
The city made the decision after seeing positive results from chips that had been installed earlier at five flooding hotspots.
The hotspots included Bình Thạnh District’s Nguyễn Hữu Cảnh Street; Thủ Đức District’s Dương Văn Cam Street; Tân Phú District’s Trương Vĩnh Ký Street; Gò Vấp District’s Lê Đức Thọ Street; and District 7’s Huỳnh Tấn Phát Street.
Bùi Văn Trường, a HCM City Urban Drainage Company officer, said the company had previously sent staff to manually measure water levels and report the results.
“But this created a problem because we could not proactively draft plans to tackle any rising problem,” he said.
An American company introduced flood-sensor chips to the city, but they were too expensive to install, costing hundred of millions of đồng at each hotspot.
After Sài Gòn Hi-Tech Park (SHTP) manufactured sensor chips, the Urban Drainage Company redesigned them to detect changes in water levels in the sewage system.
