Expanding drainage capacity of open drains by utilising the same corridor as that of the drain reserve without compromising the intended function of the drainage

Abstract

With climate change and its effects continuing to affect our lives, actions must be taken to mitigate its effects. One of the effects of climate change that Singapore experiences is the disruption to rainfall patterns. Hence, this report seeks to assess the viability of a temporary water detention area integrated into existing public spaces, complemented by an underground detention tank. This report delivers a conceptual design of a temporary water detention area coupled with an underground detention tank. The temporary water detention area will serve as a stormwater collection point before the water is channeled into the detention tank below. The stormwater collected will be discharged into nearby water sources after the rainfall event. In this study, the feasibility of the project is evaluated based on the design considerations involved when constructing a temporary water detention area in an open public space, suitable outputs of water from the temporary water detention area after the rainfall event.
