Culvert river crossing
Culvert river crossing
(OP)
We are designing a large sewage collection culvert system where the culvert size is a twin 3m high by 3m deep.
Please can anyone advise if there are any standard designs available. I am concerned not just with the physical size and installation aspects of the projects, but also the tendency for the sewage to collect at the low point.
Regards

What are the soils? Alluvial soft souls o guess.
How wide is the river? How deep beneath the river bed do you need to be?
I've heard about Culvert jacking as an option. I've never used it or seen it being used but from what I've seen online you would have cutting blade on the front of your box section. Dig a pit and then lower the culverts in a jack them off the back wall of the pit. 3x3m would be tight to get a small excactor in to remove the soil. I'd say there are people here that know Moore about it than I do, so please correct me if I am wrong
Re the low point, i presume it's a gravity system? I would ensure that there is no low point beneath the river portion. With a rising main you can have low points depending on the topography. These low points require flushing wells for maintence to clear out the solids that sit in the low point. I imagine it would he te same fi you have a low point in your culvert.
