Abstract
Most abandoned ponds can be upgraded as detention or retention ponds.
However, some of the abandoned mining ponds have been used in an improper
way such as for illegal landfill sites. The selected ponds in this study fulfil the
characteristics as retention ponds in terms of location, pond capacity, inlet and
outlet discharges and the facilities installation. Design rainfall was obtained from
MASMA manual using Bagan Serai design storm coefficient. The peak flow rate
for the drainage system was designed in 10 years ARI due to having the
development of housing and industrial areas. The results show that the peak
runoff by using design rainfall is much higher than the peak flow from current
rainfall. The volume of the pond has been designed for 10, 50 and 100 years ARI
(Average Recurrence Interval). The storage can be exceeded up to 130000m3
whereas the availability of this natural pond is up to 156000m3. Thus it is
concluded that the capacity of the ex-mining pond is sufficient to cater for the
runoff from catchment areas. The abandoned mining pond has the potential to be
developed as part of the infrastructure in future.
