Meteseh, Vulnerable to Floods and Socio-Economic Losses
Meteseh is one of the subdistricts in the city of Semarang, inhabited by 24,195 people and most vulnerable to flooding. In 2021, Semarang experienced 432 natural disasters, predominantly hydro-meteorological disasters. In the same year, flooding repeatedly struck Meteseh, bringing socio-economic losses to over 100 individuals in each instance. Several factors contributing to this include land use changes, climate change, geographical reasons, and community behavior.

Implemented Solution
Semarang Berdaya Project aims to build resilient communities through education and technology so that they can become more resilient to disasters, such as floods.

This project implements integrated zero run-off technology in the form of PoreBlock installation (porous paving blocks) and infiltration wells to reduce surface water puddles while increasing groundwater reserves. The more zero run-off technologies installed, the larger the area that can absorb water into the ground quickly, thereby reducing the risk of floods.

PoreBlocks covering an area of ​​1,000 m2 and infiltration wells measuring 18 m2 have been installed in 4 sub-locations with high flood puddles.
Zero Run-off Technology Installation
The integration of PoreBlock and infiltration wells is capable of expanding the water catchment area and accelerating water absorption compared to if both components were operated separately.

PoreBlock has the fastest paving block infiltration rate in Indonesia, which is 100 times faster than conventional paving blocks based on the ASTM C1701M-09 standard.
Hydrometeorological Disaster Prevention Education
Education is conducted for the Meteseh community to enhance understanding of the causes and prevention measures of floods, as well as to build enthusiasm within the community so that the replication process of zero run-off technology can be realized.
Changemakers Running the Project
ReservoAir is the result of the merger of two startup ventures facilitated by CCE, namely: Prom Lab (PoreBlock) and Solusibanjir.id. This merger was grounded in the realization that a single solution alone would not be sufficient to solve the flood, especially with the lack of valid and integrated data. Therefore, the solution built is more comprehensive and integrated by combining surface water absorption technology and underground infiltration wells.
Liberates Creative Colony is a collective space that has facilitated various creative activities since 2011. The team at Liberates Creative Colony is dedicated to continuous learning, contributing ideas, and expanding its network to address challenges related to water.

Learnings from the Semarang Berdaya Project
Lokasi
Soil analysis conducted pre-implementation can help to determine the appropriate project location.

The integrated implementation of Pore Block and infiltration wells was relatively effective in reducing inundation in areas with higher elevation such as Ar-Rahmah Mosque and RT 1, as opposed to RT 6 where it has a lower elevation and is located near the Babon riverbank.
Holistic and Sustainable Flood Solution
It is important to understand the flooding situation in the surrounding areas of the selected location to ensure that flooding from other areas does not impact the project. A holistic view of the flooding problems must be considered before selecting the location and project size.
