Rough ranges
Planning numbers only. Your soil, groundwater, lot and home size decide the real cost.
| Project | Rough range |
|---|---|
| Conventional system (tank + field) | about $9,000–$20,000 |
| Advanced treatment system | about $18,000–$40,000+ |
| Tank replacement | about $4,000–$10,000 |

| Risers and filter added | a few hundred to about $1,500 |
What drives valley costs
- Groundwater — the biggest factor in system type
- Lot size — less room, more engineering
- Ditches and wells — setbacks shape the layout
- Old system removal
- Yard restoration around landscaping and trees
Ongoing costs
All systems need pumping every few years. Advanced systems also need power and regular service.
