Existing sanitary sewer main with approx. 12 feet of cover. Proposed project will increase cover to approximately 22 feet, which will exceed the pipes recommended maximum cover.
Any recommendations on ways to exceed typical maximum recommended cover on pipes?

Replacing the existing pipe with a pipe of greater strength is an option, but I assume this is costly to do and is not your preference.
You could use cement-stabilised sand to provide extra support or otherwise modify the embankment to not increase the loading on the pipe. Piles are also a potential solution.
