In the long run, utilizing the Langley plant makes a lot of sense.  A pipeline and a few lift stations would probably work out as a cheaper, quicker and easier solution.  Permitting and paying for a new treatment plant, including obtaining a new discharge permit in Mutiny, would be a major process.  Over time, as capacity increases are needed, doing that for one plant, rather than two, would also be more streamlined to manage.  Overall, an interesting idea.
