Eco-composite porous concrete drainage systems: An alternative mitigation for urban flood management

Abstract

Nowadays, there are several problems cause by excessive of stormwater runoff, such as problem on drainage systems, flash floods, polluted water increase, and the environmental issue. Thus, this paper presents on eco-composite porous concrete using rice husk ash (RHA) and effective microorganisms (EM) as a cement replacement, as green technology and sustainable development in urban drainage systems. For example, drainage cover, EM drain, and EM-CSD (Effective Microorganisms Composite Scupper Drain). This new technology of drain covers have been implemented in several areas in Shah Alam, Selangor. It’s able to reduce flash floods, and also reducing the drainage vandalism. Eco-composites, which are obtained from recyclable waste materials, such as RHA, egg shells, and many more; combination with EM in porous concrete are designed, for ecological sustainability development purposes, mainly as part of urban stormwater managements. Thus, the eco-composites porous concrete quality is good in terms of concrete strength, workability, porosity and so on.
