What can i do w/a 1/2hp 600gph pump?

I am searching threads and I would appreciate anybody that knows of a thread or a design for a multi-line distribution system; requirements:

On the output side I want 3 things...
1. Recirculation for DWC and/or NFT
2. Sprinkler system
3. drip feeding.....so three lines w/adj. pressure
On the intake side I want to draw from my nute res and a ph'd ROwater res.
I have a well w/ good water...RODI filter...then would come main ROwater res. (55g plastic drum water tank)
I want to pump this to 2 2ndary res units 1 for nutes and 1 for ph'd ROwater.,
I Then want to feed the 3 different systems. I know I will have to relieve pressure to use a line from this pump for drip feeding, but will I need pressure relief for the recirculation or sprinklers? :confused: ...keeping in mind, that I might just drill wee little holes, properly spaced for high power turbo spray, or maybe a pvc system with 4/ 90 degree sprinkler heads. either would not cost too much to try.
I know I might run into problems blowing sprinkler heads off; :p so the option of having pvc or tubing w/micro drilled holes that will create a high power turbomist, resulting in "Lots of Oxygen" :) seems viable...

Just to kick this thread off properly, I will post 4 pix of my pump :cool: in case you have any questions about the specs or design...Thanks a heap to anyone willing to spend some time and help me Design this system!!! :D
If all goes well I intend to use this thread as step by step on how to build this thing and if it works...I also want to use this design for an outside nursery/greenhouse; possibly for market.
