For Discussion 



Dick - Q and A - See rough outline, change and add as 

 you see the need. 



Will Smolts tolerate the repeated pressure change across 

 successive puiap modules? 



Pressure change 18 PSI for 10 mile section 

 with 24" pipe at 2 1/2 ft. /sec 

 . Tests will be needed - a key item 



The pressure change can be reduced by closer pump 

 spacing or lower velocity in pipeline 

 Pump module depth or pump distribution along the 

 module could modify pressure impacts 



Can Smolts stand the stress of a 270 mile pipeline ride? 

 Will abrasion be a problem? 



• Abrasions unlikely with the very low velocity near 

 the pipeline walls 



Repeated trips around a test loop should show if 

 there is any problem 

 Rest stations might be needed 



Will pump impeller damage to Smolts be significant? 



Full screening from pump impellers should be 



straight forward, if needed 



Pump efficiency is not critical and fish protection 



would be given priority 



Fish would be. introduced only after a slow velocity 



build up over time
