Houston approves use of SuperCover to prevent inflow and infiltration
The City of Houston recently approved the use of SuperCover. It is now the only composite manhole cover approved by the fourth largest city in America. SuperCover is a tool designed to effectively prevent much of the issues caused by infiltration and inflow.
Infiltration with respect to manhole covers, is ground water that enters the system through defects in cast iron covers such as corrosion and pick holes. Inflow is surface-water that enters wastewater systems from above ground through defects in a manhole and manhole covers. I&I causes water treatment facilities to become less efficient in their water treatment process resulting in more manpower and equipment overhead.
Sanitary Sewer Overflow (SSO) via manhole covers in a given municipal sanitary sewer, occur when raw untreated sewage exits the system
SuperCover’s construction is comprised of two gaskets: one gasket sealing the cover to the manhole; and the other gasket seals the SureSeal insert dish to the frame of the manhole cover.
It is compatible with an insert dish. SureSeal inner dish is the fortification against I&I by providing an added barrier between I&I entries and the manhole.
SuperCover is the only composite manhole cover compatible with the SureSeal inner dish for maximum I&I prevention in the sewer industry.
