Chichester Dam Safety and Maintenance Inspection

This routine dam safety and maintenance inspection checklist for Chichester Dam supports operators in documenting conditions and issues across critical structures and systems. Record leakage measurements and flow rates at the centre wall and abutments; note rainfall and reservoir level. Inspect the concrete wall surfaces, spillway crest, intake tower, gantry cranes, bottom valve house, pressure relief drains, and tendon head pits. Check for toe seepage, new or changing seepage, discoloration, erosion, rockfill movement, upstream land movement, and accumulated or floating debris. Capture maintenance needs for access roads, boat ramp and pontoon, site security, vandalism, emergency generator and alarm siren, and tendon heads. Use findings to plan maintenance actions and ensure safe, compliant operations.
