Re-design and construction of a venturi-based drainage cleaning system

Abstract

Drainage systems are increasingly facing sedimentation and clogging challenges due to urbanization and poor maintenance practices. Building on previous research, this study aimed at redesigning and constructing a venturi-based drainage cleaning system integrated with hydro water jetting for open channels. The objectives of this project were, to redesign the components of the components of the venturi-based drainage cleaning system, to fabricate the prototype of the system components, and to test and evaluate the performance of the system. The redesigned system optimized the throat and inlet geometries to improve suction performance, and incorporated high-pressure nozzles to enhance sediment dislodgement. A prototype was fabricated using selected materials based on hydraulic analysis. Performance testing showed improved sediment removal efficiency and operational reliability under varied flow and sediment conditions. The results validate the design strategy and address the short comings in the earlier design.
