Fibrelite Manhole Installation – (6) 40K Gal Tanks – 12 Manholes

Henrich was contracted to replace (12) 54″ steel manhole covers with Fibrelite manhole covers.  The customers interest in replacing the steel covers was two fold: first, the steel covers weighed well over 100 pounds apiece and require two men to remove in order to perform inspections of the containment sumps and two, the steel covers were leaking.   By replacing the steel manhole covers with Fibrelite covers one person will be easily able to open the manholes for inspection and perhaps even more important, the sumps will be 100% watertight.
