Drainage Inspection and Maintenance

Course Introduction

Welcome to the Five-Day Course on Drainage Inspection and Maintenance! This course is designed for civil engineers, municipal workers, drainage system professionals, and contractors involved in the design, operation, inspection, and maintenance of drainage systems. Proper drainage management is critical for preventing flooding, preserving infrastructure, and ensuring environmental protection. This course will provide you with the necessary skills and knowledge to inspect and maintain drainage systems efficiently, troubleshoot issues, and implement best practices for long-term system reliability. Through theoretical sessions, hands-on activities, and case studies, you will learn how to manage and maintain drainage systems effectively.
