Q: "What does surface-watertight mean?"

"The term \"surface-watertight\u201d means that the manhole cover is protected against the ingress of natural precipitation such as rain or other surface water that occurs without pressure."

Q: "What is meant by flood-proof or backwater-proof manhole covers?"

"We speak of a flood-proof cover when it is flooded, for example, by high water. The manhole cover remains resistant to water penetration up to a certain water column. A backwater-proof manhole cover prevents water from penetrating from the inside of the manhole to the outside."
