XK4A & 4B HPP project are located on the Xekong River in Lamam District and Kaleum District at Xekong Province of Southern Lao PDR Apart from monitoring the two hydromet stations on a monthly basis, the team also performing the discharge measurement and upgrade the stations and its staff gauges throughout the monitoring period.

The Client is considering a few hydropower projects that utilize the abundant water resources of the Xekong River. This is a hydrological investigation on the Xekong River due to obtain hydrological information, which is one of the most important elements of project evaluation.

Supply, installation and commissioning of weather and water level stations) is performing a feasibility study into a proposed Pump Hydro plant in the vicinity of its current Nam Theun II reservoir area, part of the study requires several weather and river level stations.

Development of the Gauging Stations for our clients in 2026 includes surveying, and installing three hydrology gauging station is to improve hydrological data for supporting energy planning and flood forecast for early warning communication to villagers for preparing evacuation to safe zone (Emergency Action Plan Requirement) and improvement of flood mitigation procedure for protection of project facilities.

Establish Various Bore and Surface Monitoring Locations in Wetland Close to Vientiane, Laos - Water Surface Monitoring Station -A suitable location within the wetlands area was sought where a small body of water appeared to remain all year round to enable a water level sensor to be installed and maintained with relatively easy access to the site any time of the year.

Construction of staff gauges at 8 villages along downstream Kading river - to identify flood level in case of flooding in the area and is to notify and warning communicate to villagers for preparing evacuation to safe zone (Emergency Action Plan requirement as DESM comment at least one staff gauge for a village).
