I heard that sludge from each water reclamation center is sent to the sludge recycling center for treatment. How is the pipe for sending the sludge installed?

Yokohama City transports sludge is carried out by pipeline pressure. The diameter of the pipeline is 200 mm to 700 mm, and the material is mainly made of ductile cast iron pipes.

About setting, we lay pipe using internal space of large main trunk sewer and install in route without sewer main line in the same way as water pipe in public road.
