All
of the packaged metering manhole pieces are glassed together. There are
no joints or seals to allow for the inflow of water into the manhole.
This watertight integrity can result in substantial saving on sewer
bills. Additionally, TRACOM packaged metering manholes weigh
approximately 1/10th of a traditional concrete manhole, minimizing the
amount of manpower and machinery need to the install the unit.
