The Japan International Cooperation Agency has agreed to oversee a project to help recover water quality in the Tonle Sap lake in response to the appearance of a large bloom of algae. The project is part of a wider five-year initiative to improve water quality in the kingdom, according to Say Bora, the program officer at JICA. Mr. Bora said the project is expected to create an environmental database on Tonle Sap lake, plus a platform and analytic tools for monitoring the water environment there.
With a smartphone on hand, HCMC residents can monitor their domestic water use, leakage, and even online payment no matter where they are. A representative of Rynan Technologies introduces the smart water meter at a meeting with HCMC leaders in this ﬁle photo. The above features are built into what is called a “smart water meter” currently in trial use in some households in Go Vap District. The product is developed by Rynan Technologies Joint Stock Company in collaboration with Tan Hoa Water Supply Joint Stock Company. Talking with the Daily on February 13, an executive of Tan Hoa said the smart water meter would be for test use in three months to measure its effectiveness, and any shortcomings will be addressed. Device inspection will be taken, and online payment procedures figured out before the water meter can be widely used.
A new technique that helps improve water drainage in urban areas has been proposed by a Japanese company. The technique will help clean underground pipelines without digging them up, saving energy and cost, and can be applied in emergencies. The technique has been tested at a number of wastewater treatment plants in Hà Nội and the provinces of Quảng Ninh and Hà Nam. Unlike conventional wastewater treatment techniques, it does not require skilled manpower and has been proven to be effective immediately. Kobayashi Noboru, director of the Sekisui Việt Nam Pipe Solutions Company, said on February 14 that the technique can be applied along with conventional wastewater treatment system in Việt Nam in order to improve the quality of the water drainage system.
Many provinces in the Cửu Long (Mekong) Delta are taking measures to secure freshwater for farming and household use since drought and saltwater intrusion is expected to be severe in the 2016-17 dry season. Nguyễn Thiện Pháp, head of the Tiền Giang Province Irrigation Sub-department, said according to the Central Centre for Hydrometeorology Forecasting, the drought and saltwater encroachment into rivers would occur earlier than normal years. Rivers are expected to have a salt content of 2 grammes per litre 55-60km inland in March and April next year, he said. Saltwater has already flowed 20km up the Tiền River in Tiền Giang, according to the province’s Irrigation Sub-department. Tiền Giang’s three eastern districts, Gò Công Tây, Gò Công Đông and Tân Phú Đông, which are often affected by drought and saltwater, have reduced the number of annual rice crops and switched to cash crops that require less water.
While cross-border management of water resources is a necessary long-term strategy, the question is how to do it, experts say. At the November 20 session of the 24th APEC Summit, a high-ranking leader suggested developing agriculture in a sustainable manner in tandem with the effective use of natural resources, including cross-border management of water resources. Dr Dao Trong Tu, a renowned expert on river networks, said suggesting a cooperation policy in water resources management is what Vietnam needs to do. “Countries all need to develop, while water is the basis for development,” he said. Located on the lower course of large rivers, Vietnam’s water resources are facing challenges. Sixty three percent of water volume on the river systems in Vietnam is from outside the Vietnamese territory, while only 37 percent is created inside the territory. In the Mekong River Delta, 89 percent of water volume comes from outside, while the delta only has 5 percent of total volume of water.
A committee will be established to look into the construction of a 5-hectare Japan-funded aquatic centre to facilitate the study of more than 600 species of freshwater fish from the Tonle Sap and Mekong rivers, Prime Minister Hun Sen said on November 25. “I have instructed the formation of an inter-ministerial committee . . . led by Land Minister Chea Sophara as director and Sok Chenda Sophea [of the Council for the Development of Cambodia] as deputy director,” he said in a Facebook post. “Authorities and involved ministries, such as the Phnom Penh Municipal Hall, Ministry of Agriculture and Mekong River Committee, will have to attend discussions on this project.”
