x y z, to autocad, to epanet

I wish i would make rightly a question, so i am hydraulics engineer in serbia, and in a little place i have a lot of situations for proving modelloing water networks from old geodetic data, so the first and free available tool is epanet but some tools from importing coordinates x y z not work. I must to handle in a moment more thousands of data so is a tedius and hard work for drawing one by one number.
