Background
Main canals are core assets in irrigation systems because they convey water from supply sources to agricultural command areas. Irrigation canals in Cambodia distribute surface water from rivers, reservoirs, and related waterways to agricultural land during wet-season and dry-season cultivation. Main canals serve as primary conveyance channels within irrigation systems and are supported by hydraulic structures that regulate water flow, drainage, and crossings.
The Ministry of Water Resources and Meteorology is the national institution responsible for water resources management, irrigation works, and meteorological services in Cambodia. Canal rehabilitation is a public infrastructure function that can restore conveyance capacity, reduce water losses, and improve the reliability of irrigation service for farming communities. In rice-producing areas such as Kampong Thom province, rehabilitated irrigation infrastructure directly affects seasonal crop planning and local water availability.
Key Developments
On 2 May 2026, Thang Viyuthda, Director of the Department of Engineering at the Ministry of Water Resources and Meteorology, led technical officials to inspect progress on the Banteay Stoung main canal rehabilitation project, Phase 1. The inspection took place in Banteay Stoung commune, Stoung district, Kampong Thom province.
According to the ministry, the project includes the rehabilitation of 6,000 meters of main canal and the construction of 23 hydraulic structures. The reported physical progress of the works was about 75 percent at the time of the inspection.
Operational Implications
After completion, the rehabilitated canal is expected to provide irrigation water for 1,560 hectares of wet-season rice, 775 hectares of dry-season rice, and 30 hectares of mixed crops. The ministry also stated that the project would support daily water use for approximately 1,170 farming households in five villages of Banteay Stoung commune.
During the site visit, the Department of Engineering instructed the site manager and technical team to focus on effective machinery management and fuel-efficient operations, citing fluctuating fuel prices. The technical team was also instructed to follow the project specifications in order to support construction quality and keep progress aligned with the planned schedule.
Institutional Role
The Department of Engineering’s inspection reflects MOWRAM’s technical oversight role in irrigation infrastructure implementation. For public canal projects, ministry-level engineering supervision links field execution with design specifications, construction quality, and operational readiness for agricultural water delivery.
