On May 28, 2026, Sean Hinchberger, an international expert, continued his inspection of the Polavaram irrigation project in India for a second day, accompanied by officials from the Central and State Water Resources Departments. The inspection began with an evaluation of Gap-1 and Gap-2 of the diaphragm wall, and progressed to scrutinizing the borrow earth utilized for the Earth-cum-Rock Fill (ECRF) dam construction. The expert team assessed the soil storage areas, inquiring about the sources of the earth and the quality testing procedures in place. Officials confirmed that only materials certified by the Central Soil and Materials Research Station (CSMRS) and subjected to internal quality checks are being employed. Following the inspections, a review meeting was convened by Central Water Commission Chief Engineer Sarabjit Singh Bakshi, where officials presented updates on the ECRF works, retaining wall construction, and dewatering strategies. Additionally, the CSMRS expert team completed technical assessments at the site, particularly in Gap-2, to evaluate the rock-filled section's capacity to endure varying water flow conditions.
