“…The system uses grass swales, dry and wet as well as detention ponds and subsurface drainage modules. These components serve as alternatives to the traditional concrete engineering-based drainage to manage stormwater quantity and quality for the entire USM Engineering campus [17]. The system increases the lag time in the runoff, reduce the volume as well as the rate of runoff through enhanced infiltration and promote storage.…”

“…The BIOECODS is designed based on the "control at source" concept. They are substitutes to the traditional hard concrete channel systems designed to manage stormwater quantity and quality through the use of constructed grass swales, subsurface modules, dry and wet ponds [14,17]. These drainage modules provide flow attenuations in the BIOECODS and ensure eco-friendly drainage systems that will be more erosion resistant which can allow natural infiltration [16].…”

Subsurface drainage modules are important components of the Bio-ecological Drainage System (BIOECODS) which is a system designed to manage stormwater quantity and quality using constructed grass swales, subsurface modules, dry and wet ponds. BIOECODS is gradually gaining attention as one of the most ecologically sustainable solutions to the frequent flash floods in Malaysia and the rest of the world with a focus on the impact of the subsurface modules to the effectiveness of the system. Nearly two decades of post-construction research in the BIOECODS technology, there is need to review findings and areas of improvement in the system. Thus, this study highlighted the key advances and challenges in these subsurface drainage modules through an extensive review of related literature. From the study, more work is required on the hydraulic characteristics, flow attenuation and direct validation methods between field, laboratory, and numerical data. Also, there is concern over the loss of efficiency during the design life especially the infiltration capacity of the module, the state of the geotextile and hydronet over time. It is recommended for the sake of higher performance, that there should be an onsite methodology to assess the permeability, rate of clogging and condition of the geotextile as well as the hydronet over time.

“…This necessitates the development of new sustainable stormwater management and control strategies that utilize the concept of "control at source" as highlighted by Fletcher et al [5] and can promote infiltration, reuse, quality, and quantity enhancement [3,6]. The river engineering and urban drainage research center (REDAC) through department of irrigation and drainage (DID) Malaysia has developed a system called the bioecological drainage system (BIOECODS) that utilizes subsurface modules or storage tanks (Figure 1), dry and wet ponds as well as constructed grass swales to promote groundwater recharge, reuse, quality and quantity control [7][8][9]. The subsurface drainage modules are designed in different shape and patterns to increase lag time in the flow (attenuation), reduce the volume by enhancing groundwater recharge and promote storage [1].…”

The flow resistance of the existing modules in the bio-ecological drainage system (BIOECODS) is high and may lead to flood instead of its mitigation. As part of efforts to enhance the performance of the system, the river engineering and urban drainage research center (REDAC) module was developed. This study modelled the hydrodynamics of flow through this module using FLOW-3D and laboratory experiments for two cases of free flow without module (FFWM) and flow with a module (FWM) to understand and visualize the effects of the module. With less than 5% error between the numerical and experimental results, REDAC module altered the flow pattern and created resistance by increasing the Manning's roughness coefficient at the upstream, depth-averaged flow velocity (43.50 cm/s to about 46.50 cm/s) at the downstream and decreasing water depth (7.75-6.50 cm). These variations can be attributed to the complex nature of the module pattern with further increase across the porous openings. Therefore, the technique used herein can be applied to characterize the behavior of fluids in larger arrangments of modules and under different flow conditions without the need for expensive laboratory experiments.

“…OSD is a type of urban drainage technique which is based on stormwater source control. With a rapid rate of urbanization and industrialization, this technique is intended to reduce the peak discharge by slowing down the surface runoff generated by the increase of impervious area in lots [1][2][3][4]. This technique has been widely implemented in Australia since 1991 [5].…”

Abstract: This study focuses on the possibility of On-Site Stormwater Detention (OSD) underneath a residential car porch. The space provided in the car porch area can be made good of it by introducing an OSD beneath it to temporary store stormwater from roof during raining in hoping of reducing the surface runoff. The OSD is subjected to 15-minute, 10- year Average Recurrence Interval (ARI) design rainfall. This process in urban hydrology is presented by using Storm Water Management Model (SWMM). Efficiency of the OSD is also investigated by different number of orifice outlets. Modelling efforts report that one orifice outlet is preferable, and it marks approximate 95% discharge reduction at the outfall.
