Sale in jeopardy over ability to drive over septic leach lines

[Zachary Critchett]

Hey guys,

I need help! The buyers are getting hung up on the fact that in order to access the back of the property they need to drive over the septic leach lines. I spoke with the home builder and he said you can drive over them but shouldn't do it often or make it a habit. The buyers want to build a shop in back and need constant access. 

Can anyone help me get creative in finding a way to drive over those lines? Maybe a steel plate used in road cunstruction could be buried a few inches and covered with gravel or dirt? I know that may sound a little crazy but it's all I can think of at this point.

There are no other access points so going over the leach lines is the only way. 

Thank you for any support!
