We are pleased to announce that our software, starting from MiTS 3.2, now supports the latest Malaysian Sewerage Industry Guidelines (MSIG) Volume 1 – Planning Principles & Tools, recently published by the Suruhanjaya Perkhidmatan Air Negara (SPAN).
We learned that this guide will be enforced in the construction sector, starting from March 3rd, 2025.
What's New in the Latest Guidelines?
One of the key updates in the recent MSIG is the revision of the Peak Flow Factor, which has been updated to 3.4 – Previously, the factor was set to be 4.7
How is this reflected in MiTS 3.2?
In our latest version, the peak flow factor of 3.4 has been implemented as the default value for the sewerage analysis as shown below.
Additionally, we have introduced the Peak Flow Factor as a user-defined parameter, allowing users to change the value as needed to accommodate future updates. This parameter is available under
Options > Project Settings > Expand Sewerage > Click on Design
What about analysis in MiTS 2?
In MiTS 2, the analysis will continue to use the peak flow factor of 4.7 for the computations. This does not mean the analysis is incorrect; Rather, it results in a more conservative peak flow estimation and pipe sizing compared to the updated approach in MiTS 3.
