First IoT Groundwater Monitoring Station installed in the Mekong Delta
On January 21, 2025 CRMGG experts together with the Division of Water Resources Planning and Investigation for the South of Vietnam (DWRPIS) successfully equipped the Groundwater Monitoring Station Q607 near Nga Bay, Hau Giang Province with an Internet-of-Things (IoT) sensor and data transmission system.
The station is part of the National Groundwater Monitoring network, and the first station in Vietnam equipped with this innovative system. It forms part of a pilot initiative developed by CRMGG, NAWAPI and its 3 regional divisions to field-test the new technology under NAWAPI’s digital transformation efforts. The IoT approach promises significant cost-savings compared to previously available hardware set-ups. Its data and communication formats are fully customizable, in contrast to proprietary standards. Moreover, sensor and controlling components can be combined in a modular way from a wide range of manufacturers and products in the IoT ecosystem. The pilot is therefore highly relevant in view of its potential replication at hundreds of national groundwater monitoring stations in Vietnam.
The IoT setup at the pilot site in the Mekong Delta comprises water level sensors in all 6 wells and respective aquifers at the monitoring station, a weather station, a control box and solar power supply. Data is transmitted via the cellular network directly to NAWAPI servers in Hanoi.
Two similar stations will soon be installed by CRMGG in Hanoi and near Nha Trang, together with NAWAPIs respective divisions for the North and Center of Vietnam.
