Reply to comment by some_edgy_shit- in Water pipe robots could stop billions of litres leaking by Sariel007
So if they need to get new footage I assume that’s because they can’t properly survey it?
Generally debris (from sewer collapse or silt), standing water and roots are the main reasons we can’t complete them. Jetting the sewers may help in some cases but roots can still be problematic even after that.
Water level is rarely due to sagging pipe in my experience as the surveyors can get through some water. It’s normally due to the sewer network being fully surcharged either due to storm events or operational issues.

Yeah they need to get new footage. What your sayings pretty consistent to what I see. I didn’t bring up roots blocking before because the type of tire wouldn’t help with a root ball. We usually don’t get too many blockages from debris though. The contractor has an issue with trying to save time and they pull the pressure watcher like 20 feet or less ahead of the rover. I’m going to try to attach an image of an odd one

Yeah, depends on the amount of roots in my experience but generally agree it wouldn’t help. Honestly not sure if it will help at all but only reason I can see why they’d do it.
Could be you don’t see many if they are jetting the sewer as standard. Generally not the case in the UK and we’d only jet if there is a need to do so. Assume it saves money overall even if we need to pay again.

If it’s not standard for you it’s probably not standard most places in the us either. I’m split between a county and a military base. The military contract requires we us to jet 10% of the total length of line every year. Thanks for letting me know that through I made an assumption that was wrong.
