Tohoma Once Again Proves the Reliability of the Jacking Method at JSDP Zone 1

TOHOMA has achieved another milestone in the Jakarta Sewerage Development Project (JSDP) Zone 1. Using its own Micro Tunnel Boring Machine (MTBM) DN400mm, the team successfully completed a breakthrough from shaft C-12/3.3 to C-12/4.0, applying the jacking (microtunneling) method. A total of 34 pipes were installed with a total length of 82.62 meters.

With in-house technology and over 19 years of experience, TOHOMA remains committed to delivering innovative, precise, and sustainable microtunneling and jacking pipe solutions to support the future of Indonesia’s infrastructure development.
