manhole cover heights

[100-1093880151]

Are there any regs regarding the height of a manhole cover above a drain ? I need to lower a ridiculously raised manhole for my block drive project . Common sense tells me to check splash etc but I wondered if there were any regs. Secondly, what would be the best type of cover to incorporate blocks and allow Transit to drive over it ? Thanks.

There are no specific regulations governing minimum height of a manhole cover over a chamber, but there are regulations covering maximum. Basically, as long as the cover isn't obstructing the channel, I would guess it's ok. :)

The best type of cover to use on a block paving project is a Recess Tray Cover - there's a page on the site that describes their installation.
