Addressing Urban Flooding in Malaysia with MSMA and On-Site Detention Solutions
The frequency and intensity of storms have been increasing globally, and Malaysia is feeling the impact. Climate change has led to more severe weather events, resulting in flash floods and strong winds that cause widespread property damage and, tragically, loss of life. This pressing issue demands urgent attention and strategic intervention.
The Role of MSMA in Stormwater Management
To manage these growing risks, the Manual Saliran Mesra Alam Malaysia (MSMA), or Urban Stormwater Drainage Design Procedure for Malaysia, was introduced by the Department of Irrigation and Drainage (Jabatan Pengairan dan Saliran Malaysia or JPS). This manual serves as the official guideline for stormwater management and is legally required for all drainage system designs in the country.
Core Principle of MSMA: Control-at-Source
A central feature of the MSMA is the principle of control-at-source, which focuses on managing stormwater runoff where it originates. This fundamental concept shifts the burden of stormwater management away from conventional downstream solutions to a more proactive and integrated approach.
Key Control Measures Promoted by MSMA
The MSMA emphasizes two key control measures:
- On-Site Detention (OSD) systems
- Detention basins or ponds
Challenges in Real-World Implementation
Despite its promising framework, engineers frequently encounter challenges when applying these methods in real-world projects. Some of the notable obstacles include:
- High construction and implementation costs: Financial constraints can deter effective project execution.
- Difficulty in allocating adequate land space: Urban environments often struggle with limited space for necessary structures.
- Technical and compliance-related complexities: Navigating the intricate regulations and standards can be daunting.
Moreover, there is a notable lack of comprehensive references, design tools, and software to assist in the design of OSD systems and detention facilities. This gap underscores the need for targeted training and practical guidance for engineers and planners.
Training Initiatives to Bridge the Knowledge Gap
To fill this need, Ir. Dr. Quek Keng Hong, a recognized expert on MSMA, has been conducting specialized workshops since 2000. His sessions have trained thousands of Malaysian engineers, providing essential skills and technical knowledge for MSMA-compliant stormwater designs.
What Do the Workshops Offer?
These workshops offer:
- Hands-on learning: Utilizing real-world case studies to ground understanding in practical applications.
- Laptop-based training: Providing Excel spreadsheet templates that facilitate efficient design processes.
- Detailed modules on erosion and sediment control planning (ESCP): Covering vital aspects of environmental impact.
- Practical applications of hydrologic and hydraulic modeling: Focusing on urban drainage systems to ensure compliance with JPS standards.
Engineers who participate in these sessions leave equipped with the tools and know-how to design efficient, cost-effective, and compliant stormwater solutions that meet JPS standards. This empowerment translates directly into better flood management and enhanced urban resilience.
