arcgis desktop - Draw Line from Point to existing Line

I am working on a water network, I want to draw a House Connection pipe from a house meter to nearest existing water line, I tried using python script, I could just find the nearest line. I also want a line drawn from Point to nearest water network. Can I get a part of script which draw all the house connection lines automatically with existing nearest water line?

I am working on ArcGIS 10.2.
