Hi Aaron, I think the biggest obstacle  ( at least in the past) was the cost associated with this process. Poseidon worked out a new system and it may become the model for many more plants around both our country and the world over. A new day is dawning and our water shortfall issues may have a viable solution now. All good news as far as I can tell.

Hi Gary, I think so as well. It does seem odd when you think about it, that with all the oceans in the world, that there should ever be a shortage of potable water to drink. Now it appears the solution has been worked out but we will need many of these plants to take up the shortfall of rain and the lack oof melting snow from the mountainous areas.

Hi Sally, I couldn't have said it better. Many Thanks. This new system will likely prove it's worth over time and I am sure we will see many more of these plants take up the gap between supply and demand. I think eventually at least for San Diego that has to buy 90% of it's water, this is the very best solution.

Hi Mana, I am believing that now that there is a track to run on and the obstacles have been overcome, it will provide the way for more plants to be approved and built along the coast.

Hi Lenn, There has been so much discussion and actions to prevent approval on the basis that the marine life will be harmed and the discharge of 50% of the sea water back into the ocean will have a very high salt content and may play havoc with the saline balance and that the sea life ordinarily found where the water will be discharged will in some way be harmed. We shall see but I expect the ocean has a lot of water in it and it would probably take more time than the earth has to oversaturate the water with salt. As for the marine life, the Aqua Hedionda Lagoon is a man-made lagoon to grow sea life to offset  any marine life that was originally lost by the Power Plants use of the seawater in its filtration system. Poseidon has overcome all these and many other objections with its plans and finally won out. It even has to buy carbon credits to offset the energy it uses to run the desalination plant and to bring the water in and filter 1/2 of it for drinking water. They didn't miss a thing here and Poseidon satisfactorily addressed every issue.  

I suppose anything is possible Steve but I'd hate to think about,What if they did,lol. Like " Enhanced, Fully Enriched Water".  It sort of gives the " Don't 'Waste' Water" a whole new meaning. :-).
