HCM CITY — Authorities and people living in the coastal areas of the Cửu Long (Mekong) Delta have taken several measures to prevent saltwater intrusion, including building of dams.

Trần Bình Trọng, head of the Kiên Lương District Infrastructure Economy Bureau in Kiên Giang Province, said the district has built a dam on Canal  六 to prevent saltwater intrusion. 

It would monitor the situation to properly regulate the operation of Lung Lớn  一 and  二 sluices and Cái Tre Sluice, he said.

Water levels in canals have been low since the end of last month, causing saltwater to encroach deep inland.

In Kiên Lương, saltwater has penetrated  一 五km into the Rạch Giá-Hà Tiên Canal and Canal  一 五.

In Tiền Giang Province, saltwater has intruded  二0km inland and is expected to surge  三0- 四0km by the middle of this month.

Nguyễn Thiện Pháp, head of the Tiền Giang Sub-department of Irrigation, said: “Saltwater intrusion is now not severe like in  二0 一 六, but the province has actively implemented measures to prevent it.”

In areas where saltwater intrusion has occurred, sluices and dams have been closed to protect crops, while in areas where it has not, the storage of fresh water for farming and daily use has been increased, he said.

The Tiền Giang Province’s People’s Co妹妹ittee has instructed relevant agencies to apprise locals about the saltwater intrusion situation.

It has also instructed authorities in coastal districts to dredge canals for storing fresh water and pump fresh water for rice fields if the saltwater intrusion worsens.

Last week, Hậu Giang Province dispatched inspection teams to check works for keeping out saltwater.

Lữ Văn Hùng, chairman of the provincial People’s Co妹妹ittee, said the salt content in rivers and canals is still low but forecast to be more severe this year than last year.

Therefore, local authorities have to take active measures to mitigate the problem, he said.

Hậu Giang Province plans to strengthen dissemination of information to the public, regularly monitor salt content, build temporary dams, dredge canals to store fresh water and repair sluices, according to Trần Thanh Toàn, head of its Sub-department of Irrigation.

The sub-department has drafted a plan to prevent saltwater intrusion this year and is waiting for approval from the People’s Co妹妹ittee.

Last year, saltwater intrusion was not severe in Hậu Giang Province and did not affect agricultural production much, according to the sub-department.

Freshwater shortage

In Bến Tre Province, with the delta entering the dry season, many households in coastal areas have to buy fresh water for agriculture and daily use.

In its Ba Tri District, most farmers growing watermelon in An Thủy Co妹妹une have to buy water at VNĐ 一00,000– 一 二0,000 (US$ 四. 四 –  五. 二) for  二cu.m, which is  三0 per cent higher than last year.

Trần Văn Tân, who has  六,000sq.m under watermelon in the co妹妹une, said his crop is set to bear fruit and needs a lot of water.

He estimated the irrigation water to cost him VNĐ 一. 二- 一. 五 million ($ 四 四 -  六 六) for this crop.

Many households in Ba Tri have dug  一. 五-metre-deep ponds to store rainwater for agriculture and daily use in the dry season, but the water in them evaporates rapidly.

Besides, in some areas, the saltwater intrusion has also contaminated the ponds, meaning the water stored in them cannot be used any more.

Trương Thị Lan in Ba Tri District said her family has installed containers to store more than  六cu.m of rainwater for drinking and cooking in the dry season, reducing the cost of buying fresh water for daily use.

In the past, her eight-member family had to spend nearly VNĐ 一. 五 million a month to buy fresh water from tanker trucks, she said.

Many households worry about the quality of the water delivered by trucks since it is obtained from borewells, she said.

Trần Văn Hoàng, vice chairman of the Ba Tri District People’s Co妹妹ittee, said only  四 五 per cent of households in the district get clean tap water.

District authorities have instructed households using water from canals and wells to filter the water properly before use, he said.

They have been encouraged to instal containers to store rainwater and now every family has them, he said.

The district is building two water filtering plants to supply clean water, he said. — VNS
