....... The other requirement was that the pipe be of hard impact duty ...... so if lets say a backhoe drives thru the stream for example, it cant crush the pipe.
Its my contention is that in lieu of this, the 2ft thick reinforced concrete box culvert itself affords an encapsulated protective...
I put in a box culvert many years ago to cross a stream to reach an isolated residential land plot. The bottom floor of the culvert was left as bare concrete (I took this project on as I have never did one before! : )
The culvert was 30 tons! The crane was massive and cost $2,500.00 for the 30...

@bimr:
What are you running, a gravity sewer or a force main?
Forced lateral (pumped) ...... with siphonic drain function as a back-up.
This 2" lateral is 450ft long!!
The vertical height differential from starting elevation to end discharge into the township's gravity sanitary sewer is 40ft...

Thanks for your response!
The township sewer engineer is agreeable to this, but said I would have to get PA STATE approval and permit if they allowed this.
...... and other authorities may also want permissions as well (EPA, etc)
Hello Eng-Tips.com community! :)
I need to cross-under a four lane state highway to get to the township's gravity sewer main on the other side.
In lieu of pneumatic tunnel boring (expensive) the ideal point of cross-under is at an existing state owned box culvert with a low flow stream...
