Catchment Size to Effective Tank Volume Relationships for Individual Lot Stormwater Detention System in Malaysian Detached House

This paper describes an individual lot stormwater detention system that consists of multiple precast concrete modular green pavement units, developed by the authors. The tank size is determined at 4.40 m W, 4.70 m L and 0.45 m D with an effective tank volume of 3.93 m3 after being filled wit...
