Finally! Once again, PT Tohoma Mandiri succeeded in making a breakthrough using the Jacking Microtunneling method on the Makassar WWTP B1 Project, Makassar City Main Waste Water Channel Work Package. The SPAN with the Jongaya Canal crossing that we successfully completed from Departure MH10343 to Arrival MH10340 has a length of 150.66 meters with 62 pipes.
The Microtunneling Jacking method allows us to deal with various obstacles. This includes the drilling route passing under the Jongaya Canal, which is a densely populated area so we have to drill without having a negative impact on the environment. The entire process is also carried out carefully and meticulously, ensuring that each step is carried out optimally and in accordance with procedures.
PT Tohoma Mandiri has successfully undertaken a project aimed at enhancing wastewater management in the urban areas of Makassar City. Serving as a Sub-Contractor, we specialized in microtunneling DN1000mm, with strong support from PT PP as the Main Contractor. Together, we are committed to advancing sustainable infrastructure solutions for a cleaner and more efficient urban environment.

Minister of Public Works and Public Housing (PUPR) Basuki Hadimuljono accompanied by the Mayor of Makassar Muhammad Ramdhan Pomanto visited the Wastewater Treatment Plant B1 installation project in Makassar on July 27 2023. This project has been running together with PT. PP (Housing Development) as Main Contractor.
During this visit, the Minister of PUPR conducted a review of the Centralized Domestic Wastewater Management System in the Metropolitan Sanitation Management Investment Project (MSMIP) program. This program aims to improve wastewater services in urban areas.
PT Tohoma Mandiri as one of the sub-contractors in the WWTP B1 Makassar project is working on a wastewater pipeline network construction project using the jacking microtunneling method. In addition, we always prioritize occupational health and safety, and ensure that the projects we work on are carried out optimally because they are carried out by our team of professionals in this field so as to achieve the best results.

Microtunneling or the process of building tunnels using a drilling machine (Microtunnel Boring Machines, MTBM) combined with jacking pipe techniques to install pipes underground in one driving. This process is carried out with the aim of avoiding open excavation.
In other methods, it often causes congestion because it requires diverting traffic lanes. However, Microtunneling operates underground and does not disrupt with traffic areas, so it does not cause congestion or noise problems. By involving the use of a remote controlled drilling machine, Mictotunneling does not require large trenches or open pits there by helping to maintain vegetation around the project area.
From the factors described above, the microtunneling jacking method is the right solution for projects in areas with dense population and traffic. PT Tohoma Mandiri has a team of professionals who are experts in the field of microtunneling, with extensive experience and expertise. Get the best work with us as a reliable partner in efficient microtunneling solutions to meet your project needs.

The Microtunneling of DN1000 work using the jacking method at this time is the longest span in the Palembang B2B WWTP work with a length of 143 m. Our team managed to achieve an average production progress of 12m/day with a maximum achievement of 16m/day.
The trace that we are working on does not experience significant geological obstacles, this is supported by the results of the analysis carried out by the geolytic team which shows similarities to the previous spans and traces that we have successfully worked on. As a result of good perfomance and proper supervision, the project is running well and achieving optimal results.

The microtunneling work on this route is special, where the drilling route passes under the Ampera Bridge, the Terminal. the Main Market and also the Palembang City LRT Overpass.The area is a critical area and crowded populated. As for the extra challenges that we have to face in this project, we need to drill in dense areas without affecting the surrounding environment such as traffic jams or technical problems in public facilities. Beside the existing of challenges, our team managed to carry out the project in a professional work with the best result.
Doing such a prominent project is pushing our team to give the best skill and science considering its safety and quality. Thus we are supported by precise information regarding geologist soil structure clearly provided by responsible parties. During this stage we expedite the jacking process, targeting 11.62 meter per day and proudly able to achieve 16.00 meter as the best result. There are some soil types that we have faced on this area such as clay, sandy soil, and silt.

PT Tohoma Mandiri is the sub-contractor of Adhi – Jaya Construction which has been working on the North Zone Wastewater Pipeline Development Project since the end of 2021 in Pekanbaru City. This project uses the Jacking Pipe – Microtunneling System method using a drilling machine (Microtunnel Boring Machines, MTBM) and is combined with hydraulic engineering from the departure shaft to the arrival shaft in (one drive).
PT Adhi Karya visited and reviewed the progress of the project being carried out by PT Tohoma Mandiri as a Sub-Contractor for the installation of 1000mm diameter RCP pipes. This visit began with a safety briefing before entering the MH-106 pit/shaft area, in accordance with the project’s K3 SOP.
Next, the Adhi Karya team entered the pit area and received an explanation of the progress of the work from the Project Manager of PT Tohoma Mandiri. They were immediately guided by the Tohoma team to go to the control room area, shaft area, and slurry system area. This work technique is very safe and environmentally friendly because it is done without open excavation so it does not damage the ground surface facilities for laying pipes with a depth of +/- 10 meters from the surface. Excavation is carried out from the control room by experienced Tohoma operators.
