Project Background:

The Study covers a catchment area of 133.5 ha including Institut Perguruan Perempuan Melayu (IPPM) Melaka. This area is surrounded by housing estates and villages, including Kampung Durian Daun Dalam, Kampung Mata Kucing, Taman Peringgit Jaya and Taman Seri Cempaka. The main drain that pass through the catchment area evolved from earth drain at upstream to concrete drain in the institute Perguruan's compound, and exited into earth drain again before discharge to Sungai Melaka.

As a result of undersized local drains and culvert, low platform level in the Study Area, tidal effects, lack of maintenance for the existing drainage system caused by shrubs, sludge and rubbish, flash floods occur in most parts of the study area.  The floods usually last more than 2 hours, and the current facilities can no longer withstand the increasing runoff.  In addition, the contribution of grey water from existing residential areas has caused degradation of water quality in the existing water body, and therefore stormwater management facilities are needed to counter for the flooding faced by the population in this area and to ensure clean discharge water to Sungai Melaka. The Stormwater Management Facilities to be constructed are for an area alongside the main drain which often facing flooding problems.

Proposed Drainage System:

This project was proposed with the prime objective to set-up an example and showcase of the application of MSMA for urban stormwater management and flood prevention project in Malaysia, particularly in the state of Melaka. It was also aimed to study the existing hydraulic and hydrologic characteristics, as well as the water quality conditions of an urbanized drainage system subjected to flood and tidal effects.

This design system includes several components namely engineered waterway, resizing of culverts, constructed wetland and pumping station. Effects have been made to ensure no recurrence of flooding after the project is completed. Further improvement of water quality is expected with the construction of constructed wetland.
