@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...
@FEL3
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...
