Time flies when you are having fun. It is hard to believe that nearly three years have passed since the release of the Second Edition of MSMA (Manual Saliran Mesra Alam Malaysia or Urban Stormwater Management Manual, or MSMA2) by the Department of Irrigation and Drainage (DID) in July 2012. It is required by law for all engineers in Malaysia to design drainage works to comply with the requirements of MSMA.

In the last three years, the industry is faced with a number of issues in complying with the requirements of MSMA2.

These include changes in design parameters like storm, temporal patterns, peak discharge, hydrograph and changes in the storage volumes of On-Site Detention (OSD), detention basins and sediment basins. Based on our research work, the following changes were found for Kuala Lumpur:

1. The design storm has increased by up to 126% for 10 out of the 14 stations in Kuala Lumpur.
2. The design discharge using the Rational Method has gone up by up to 131% for commercial and city area.
3. The peak discharge using the Time-Area Method has increased by 127%.
4. The Site Storage Requirement for OSD for a factory site has increased by 190%.
5. The volume of detention basin for a site has increased by up to 130%.
6. The volume of wet sediment basin has increased by 165%.
7. The requirement to provide rainwater harvesting according to the procedure outlined in MSMA2.

The benefits of attending the Seminar are as follows:

1. You will find out about important changes and new requirements in MSMA2 that affect drainage design in peninsula and Sarawak.
2. We will show you a different approach of computing OSD using MSMA2 that will reduce the storage significantly compared to the Approximate Swinburne’s Method in MSMA2.
3. We will show you a proposed system that combines both rainwater harvesting and OSD for typical houses which will optimise the total storage required.
4. You will get special tips from the expert and receive powerful tools that will make your design more cost effective.
5. You will get MSMA2 spreadsheets worth a total of RM2,380 for free. Plus free Lite version of the MSMAware software!
6. You will gain 12 CPD hours by BEM (pending) while learning about MSMA2.
