Green infrastructure (GI) is an environmentally friendly technology designed to reduce stormwater runoff and conserve groundwater by mimicking natural hydrological processes. This study aims to evaluate the effectiveness of household-scale GI in achieving zero runoff and supporting groundwater conservation. The research involved pre- and post-construction monitoring of rainwater harvesting systems, infiltration wells, biopores, and rain gardens in a residential area in Pekanbaru, Indonesia. Methods included rainfall data analysis, groundwater level monitoring using data loggers, and runoff volume calculations based on a two-year return period. Results indicate that GI reduced surface runoff to near zero during moderate rainfall events. Although GI facilitates rainwater infiltration into the soil, the monitoring results showed that groundwater table elevation did not increase immediately following rainfall events, where variations in groundwater level recorded by the data logger exhibited temporal fluctuations that were not statistically correlated with rainfall occurrence.

摘要

Green infrastructure (GI) is an environmentally friendly technology designed to reduce stormwater runoff and conserve groundwater by mimicking natural hydrological processes. This study aims to evaluate the effectiveness of household-scale GI in achieving zero runoff and supporting groundwater conservation. The research involved pre- and post-construction monitoring of rainwater harvesting systems, infiltration wells, biopores, and rain gardens in a residential area in Pekanbaru, Indonesia. Methods included rainfall data analysis, groundwater level monitoring using data loggers, and runoff volume calculations based on a two-year return period. Results indicate that GI reduced surface runoff to near zero during moderate rainfall events. Although GI facilitates rainwater infiltration into the soil, the monitoring results showed that groundwater table elevation did not increase immediately following rainfall events, where variations in groundwater level recorded by the data logger exhibited temporal fluctuations that were not statistically correlated with rainfall occurrence.
