Pumping to and sihponing from and Impoundment
(OP)
Anyone have any experience with the design of a waterline used to pump to AND siphon from and large water storage impoundment?
I have a client who only wants to use only line for both purposes, obviously not at the same time. For air release valves for pumping, I have spec'd manual ball valves for air release maintenance. My concern is with sizing the pipe for 350 gpm up to the impoundment, but then utilizing the same line to siphon back down to a water transfer station. This only one part of a larger overall water trucking operation for shale gas development. The line is approximately 4200LF and has an overall elevation change of 400'.
Thanks

A lot will depend on the profile of the pipeline which you have not presented.
RE: Pumping to and sihponing from and Impoundment
Top of berm is 1220'
Bottom of impoundment is 1185'
Outlet at siphon is 820'

This type of arrangement is common for water systems.
The issue that will be of concern is the high water pressure. You probably will need some type of pressure regulators on the water use points to drop the water pressure down.
I assume that you know that you can not allow water to reverse through the centrifugal pump that is generally used for this application. You should also use a pump pressure controller that will assist the pump startup when operating against the high static pressure.

I'm simply looking for some information about using one line, instead of two to pump and sihpon. I'll check around elsewhere for more information.

Thanks for the link - I'll scour them one more time.

I've found plotting the pipeline profile, along with the siphon HGL (plus atm less vapor pressure) to be useful.
