Statewide cost drivers here are hard ground, terrain and remote access. Locally, hard ground and desert setbacks affect excavation. That is why a conventional system in Nevada can land well above or below the national range of $3,500–$8,000.

What conventional systems are for
A conventional system uses a tank plus a gravel or pipe drain field. It needs deep, well-drained soil and adequate space, which is why it is the cheapest option when the site allows it.
