Water crisis looms as short monsoon, El Nino hit southern
reservoir
A large reservoir that supplies water for Ho Chi Minh City and
nearby provinces has seen its water level falling rapidly, signaling a
possible severe shortage for the whole region, experts said.
“Low rainfall as an impact of El Nino has
significantly lowered the water level of Dau Tieng Reservoir,” said Nguyen
Van Dam, director of the HCMC Irrigation Service Company.
The reservoir on the Dong Nai River, whose
main tributary Saigon flows into the East Sea, supplies
water for vast farmland areas in Tay Ninh, Long An, Binh Duong and HCMC. It
is also sourced for tap water for 10 million people in HCMC and Binh Duong.
Dam said low rainfall upstream has caused an
increase in salinity.
“The rainy season is predicted to end one
month earlier than in previous years and this will exacerbate the problem,”
he was quoted by Thoi Bao Kinh Te Saigon as saying.
The water level at Dau Tieng Reservoir has
hovered around 21 meters, compared to the average 24.4 meters in previous
years.
Meanwhile, the demand for water for irrigation
has been on the rise due to newly-cultivated areas in Tay Ninh and Long An.
Tap water shortage
According to Saigon Water Corporation
(Sawaco), the company’s plants cannot treat saline water in the river.
The company said it had to suspend tap water
services several times because the salt
concentration in the water was too high.
The company also warned about pollution in
the river and the increased risk of coliform bacteria contamination.
Last
week, water resource management agencies in Tay Ninh, Long An and HCMC have
met to discuss solutions for the potential shortage.
Water will be prioritized for tap services
and aquatic farming while crop farmers may have to switch to other plants
that need less water than rice, Dam said.
“Dau Tieng Reservoir has cut back its
discharge to save water for the final months,” he said, adding that a
reservoir nearby will be sourced to minimize the impact of the water crisis
that will likely affect the whole southeastern region.
