Manhole cover that lets water run off in and traps odours in

Looking for solutions to the following: property have combined waste drain that we need to run rainwater run-off in to. The drain is too shallow to cut into it so i think the solution needs to be via the manhole cover. There are lots of covers with holes that would easily accommodate the water run-off but the odours from the drain would find their way into our house as cover is right next to bedroom. Anyway know of a cover that let's water in and traps odour inside?
