Muffin Monster Manhole – JWC Environmental

Monster Manhole – Pre-Packaged Sewage Grinder

The Monster Manhole is a pre-fabricated sewer manhole with a sewage grinder that is fully assembled and ready to install. This FRP manhole is an excellent solution when a sewage grinder is needed but there is not enough room for conventional installations. Installation is easy – just dig down to the sewer line, create a concrete pad for the fiberglass manhole unit to rest on, and tie in the sewer lines.

It is a perfect solution for sewage and commercial and residential facilities as well as pump stations that are difficult to access.
