My little drawing didn't display correctly. Here's another attempt. The house would be to the left, then the speptic, then the d-box and laterals. "`" = grass. downhill |````*```` |````|```` |`O--o---` downhill |````|```` |````````` flat The pump operator indicated that the laterals should all interconnect something like this. |````/----\```` |````|----|```` |`O--o----|` downhill |````|----|```` |````\----/````` Is there any easy way to map out how and where all the lines are laid out?
