Inflow: A USA-But Not International-Priority

Most international countries that mold composite manhole covers have one sewer line for both sanitary and stormwater. Thus, the concern for rain inflow into the sanitary sewer is not a priority. CAP`s covers can eliminate inflow through the cover. Most imported covers are not watertight and will allow substantial I&I.

Hydrogen Sulfide Corrosion - A USA Focus

Because the devoted sanitary sewer system in the USA is not as dilute as combined sanitary + storm sewers, US hydrogen sulfide levels reach very high ppm. Thin walls of international frames can break exposed to heavily corrosive environments.

Traceability? Root Cause Analysis? Good Luck with International Product...

CAP covers and frames have molded-in manufacturing dates. If your import cover has any issue, what will your importer do to help? Sell you a new - potentially still defective - product.
