I am trying to find the minimum slope (gradient) for a rising main (sewage). I presume that slope "up" or "down" is irrelevant as I am worried about both the location of air valves and scour (washout) valves.
While I'm at it, any maximum gradient?
Also, are scour valves required at all low...
I am designing a manhole with a depth of 8m. Is there any special considerations I should be aware of?
does it have to be a huge chamber (& what is a rest chamber)?
I'm a civil (mainly Environmental Office Work) engineer who has just found myself in Africa building small bridges. What's around are bricks and cement, and the odd steel beams.
Having never partaken in this type of work before, I would welcome any tips or comments.
I intend to build masnry...
