Force Main Back Pressure Valve or Pressure Relief Valve

[Builder604]

I have a project where we have a pump station that will pump over a hill and then down to a dip at a directional bore under a creek and then to the discharge MH. The discharge MH elevation is lower than the pump station. Our initial thoughts are to install a Pressure relief valve/back pressure valve at the discharge point. This valve would keep the valve closed and pipe full when set to the static pressure between the high point and the valve. The pump would TDH would then be based on the friction head of the full length of pipe, the static head from pump to high point and static head from pressure relief valve to high point. Does anyone have any input on how well a pressure valve would work for a force main application like this? We are concerned with clogging.
