Water collection chamber

[berisford]

I want to make a water collection chamber,preferably with concrete man hole chamber,how do you go about sealing a 2" hole for the outlet if at all possible,can you drill those things without having them ready made. It would be 1m deep 1.5 wide with outlet near bottom,with 80mm pipe in and 100mm overflow. Thanks

Thanks for that,had thought of pouring concrete in the bottom and have the outlet pipe coming up through the concrete,but the outlet would be at wrong angle.
