Meteseh is one of the urban villages in Semarang, Indonesia, inhabited by 24,195 people. It is the most vulnerable village to flooding. Based on 2021 studies, Semarang has had 432 natural disasters and 63.11% of these disasters
are hydrometeorological, specifically flooding.
In 2021, several housing estates in Meteseh experienced repeated flooding cases that affected 120 people in each case. Some of the contributing factors are changes in land use, climate change, geographical phenomena and the community’s lifestyles.
The pilot project “Semarang Berdaya” applies integrated zero run-off technology in the form of PoreBlock installations (porous paving blocks) and infiltration wells to reduce surface water logging while increasing groundwater
The integrated zero run-off technology in the form of PoreBlock installations (porous paving blocks) and infiltration wells is a simple technology and is easy to replicate so that it is able to deal with flooding problems more quickly. The more zero run-off technology is implemented, the wider the area that can accelerate the absorption of water into the ground so that the risk of flooding can be reduced.
Installation of PoreBlock technology (porous paving blocks) and infiltration wells to reduce surface waterlogging and provide groundwater reserves.
PoreBlock has the fastest paving block infiltration rate in Indonesia. Based on the ASTM C1701M-09 standard, it has 100 times faster rate than that of the conventional paving blocks.
Education is carried out to the Meteseh community to increase public understanding of the causes of disasters and the preventive measures, as well as to build the enthusiasm of the surrounding community in replicating zero run-off technology.
The implementation of zero run-off technology and flood prevention education aims to reduce the risk of flooding, and increase public awareness and interest to replicate this technology.
In order to create a real impact on the community and the environment, we are working to reduce water runoff and increase water reserves in Meteseh.
