  A PCP-BBB was an effective green infrastructure for stormwater management.

Abstract

This study assessed the feasibility of pervious concrete pavement (PCP) followed by a bamboo bioretention basin (BBB) with Dracaena sanderiana for urban stormwater volume control and water quality enhancement. Two PCPs (nPCP and tPCP) having a permeability of ∼4.5 mm/s were prepared with optimized mix designs. A control impervious concrete pavement (CP) was also prepared. Results showed that both PCP-BBB’s outperformed CP-BBB not only in runoff volume reduction, but also in pollutant removal; both PCPs removed a considerably high amount of pollutants, especially in fecal coliform and phosphate removal. tPCP-BBB improved water quality better than nPCP-BBB in terms of chemical oxygen demand and pH. Additionally, D. sanderiana grew healthier in tPCP-BBB than in nPCP-BBB. Production costs for tPCP and CP were similar, whereas nPCP production was twice as expensive.
