Now you can stop
unwanted inflow of rainwater through manhole covers with INFLOWSHIELD®. This simple, sturdy device saves
tax dollars and the environment.
Manhole covers are
a major contributor to rainfall induced I&I. Test indicate that a leaky
manhole cover under only one-inch of water will allow an inflow rate of
.20 to 7.5 gallons per minute. While the problem of leaky manhole covers
is one of the leading contributors to system I&I, ironically, it is
the easiest and most cost-effective problem to remedy.
INFLOWSHIELD® manhole cover inserts
are custom sized, and manufactured from 18 gauge 304 stainless steel.
This superior construction provides superior durability and strength that
far exceeds that of plastic inserts.
