Rapid urbanization has many negative effects on environment such as deterioration of water quality contributed by pollution. In terms of stormwater management, even with the introduction of Manual Saliran Mesra Alam (MSMA) in 2000 (Urban Stormwater Management Manual for Malaysia), numerous new technologies have yet to be examined in detail, especially the relationship between water quantity and quality. Implementation is based on the restoration and optimization of the ecosystem. In this study, it has been reviewed and introduced the MSMA software in regard to water quality and discharge analysis for the future study. MSMA SME Design Aid and Database System knowledge base consists of a compilation of information and data relevant to stormwater treatment including algorithm for components, available design standard, technical guidelines, components design, supplier contact information, and images of each components and drawings. MSMA SME Design Aid and Database System framework consists of four main modules: user requirement input, analysis and design phase, prototype phase and user testing. There are 28 main components which have important role for visualization of any given catchment such as rainfall data, green roof, bioretention, constructed wetland, porous pavement, rainwater harvesting system, grey water reuse system and checking tools items. Currently, the 4 key components, such as bioretention system, water quality volume, lined drain design and bridge afflux estimator, have been developed in this study. MSMA SME Design Aid and Database System is able to assist engineers and developers in terms of management and improvement of water quantity and quality entering urban rivers from urban regions. This system is also helpful when an expert-level judgment is needed repetitively for a large amount of cases, like in the planning of stormwater BMPs systems for an entire city catchment.
