Manholes are used to connect public sewage lines running across the underground drainage network. They provide a passage for human entry and exit. Ashirvad Manholes are made of 100% virgin UV-stabilized polyethylene material and are available in different sizes- 500mm, 600mm, 800mm and 1000mm. Two variations of manholes are available in the Ashirvad product portfolio, i.e., three-way and five-way entry manholes.
- Manholes can be installed wherever there is a longer sewage connection, change of direction, new connections, converging inlets, fall of sewage or gradient incline, and to disconnect private sewage collections.
