WHAT IS A SUPERCOVER?
-
SuperCover is the solution to infiltration and inflow (I&I) of sanitary sewer overflow; designed by sanitary sewer overflow professionals.
-
SuperCover is a non-metallic, fiber reinforced composite manhole cover; capable of withstanding traffic loading requirements that meet or exceed HS-20 & HS-25 rating at an economical value for all municipal budgets and projects.
-
SuperCover has been tried and tested through third party lab testing, university evaluation, and approved by TXDOT. *not an endorsement*
-
SuperCover is designed and distributed in Texas for the Lone Star State quality and durability. SuperCover has been implemented in cities and municipalities across Texas.
What are SSO's and I&I's (Sanitary Sewer Overflow) (Infiltration & Inflow)
-
I&I is the infiltration and inflow of excess water that enters wastewater pipes from above and below ground water.
-
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 cover.
-
I&I causes water treatment facilities to become less efficient in their water treatment process resulting in more man power and equipment overhead.
-
Sanitary Sewer Overflow (SSO) via manhole covers in a given municipal sanitary sewer, occur when raw untreated sewage exits the system through defects in cast iron manhole covers.
HOW DOES SUPERCOVER STOP AND PREVENT I&I?
-
SuperCover’s construction is comprised of two gaskets, one gasket sealing the cover to the manhole; and one gasket that seals the SureSeal insert dish to the frame of the manhole cover.
-
SuperCover 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 industry
