Septic Tube Observation Port Replacement?

Hey all,

So i have a septic box mound (essentially a mound system that is enclosed in treated wood). On each end of the box, there is about a 4" wide PVC pipe coming out with a cap covering each one. When I open the cap and look down, I can see sand about 3' or so down the tube. Each tube appears to be made of 2 parts: An upper blue portion that is solid and a lower white portion that has 4 holes drilled into it. I believe these are observation ports - is that correct?

The reason I'm asking is I was mowing the lawn up there and accidentally nicked the top of one - it busted the cap off and cracked / split the top of the tube itself. I'm wondering if this is as simple as just pulling out the upper end of the old PVC (the portion that is blue - approximately 1.5 feet long) and putting in a new one with the cap. Is that all I would need to do?

The pipe seems pretty solid in there, is it okay to dig around it to remove it?
