Sewer Pipe Longitudinal Design System

Technology / Service Summary

A software for performing hydraulic simulation of sewer pipe models. Runs on the widely adopted AutoCAD and BricsCAD worldwide. Automated calculation functions such as hydraulic calculations, longitudinal designs, and quantity calculations for stormwater, sewage, and combined treatment types are provided. Japanese and English are supported.


To create sewer pipe models and output the results of hydraulic and longitudinal designs for stormwater, sanitary sewer, stormwater + sanitary sewer for both new and existing sewer systems by automatic calculation.


The design results are output to the drawings and reports according to the design parameters and expression style of the region. All data is stored centrally in the culvert object in the culvert plan, so the consistent design is possible.


・Contribute to infrastructure development in developing countries not only in Japan, but also overseas, and contribute to reducing the pollution of rivers and other bodies of water.
Hydrological calculations can be performed using precipitation information due to climate change as a parameter, and contribute to renewal plans by verifying the flow capacity of pipelines.
We have both Japanese and English versions of the software, so data compatibility is advantageous in projects such as ODA.
We have experience in explaining Japanese design technology using PDPs in a technical support project in Vietnam, and it is advantageous for similar projects.
