Japanese Sewerage Exhibition 2018

From July 24th to 28th, in Kitakyushu city I attended the Japanese Sewerage Exhibition. Among interesting things, a drone for pipe inspection with automated condition assessment software and a small diameter drilling machine developped for telecom cable trenchless installation. Diameter 300mm, up to 200m span!
