rising main design
rising main design
(OP)
Hi all
I am trying to design a rising main of about 1.4km. The main passes through a stream, roads and field. Can anyone tell me what I should consider to design a main? I know that the main has to be 1.2m deep under road, 0.900m through field and 1m under stream. Additionally I should use air valve and wash out but I don’t know where I should put them.
Thank you for your help.

RE: rising main design
It is good practice to avoid an air valve except on startup. You want to minimize air in the forcemain, not add it. You probably will not need a cleanout either. You should have provision to drain the forcemain for maintenance.
See the attachment.
Pumping Station Design by Robert L. Sanks is a good reference book.
