Doing away with Sump Well in two-stage pumping
We had commissioned a lift irrigation system in 1998 in two stages which is still in working condition till this date.
Now due to some problem of ownership of land where sump well is located, we want to do away with the sump well and put an in-line pump instead.
The general set and other information is as given in the attached sketch.
Can anyone advise how the hydraulic gradients will behave?
Will there be threat to the pipes in the first stage?
Is the proposed system advisable?
Your experience much appreciated.
