What the drawing needs to explain

Cost factors for this service
Costs depend on site area, excavation, soil and available connections. Ask for the scope and selected specification to be described separately.
Bring this to the discussion

The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
