A failed field quote should start with tank levels, distribution box condition, soil/site constraints, and whether the old field can be repaired before replacement.
| Project | Typical cost | What changes the quote |
|---|---|---|
| Drain field diagnosis or distribution box check | $300-$1,600 | Often needed before a contractor can tell repair from replacement. |
| Conventional drain field replacement | $5,350-$21,400 | Depends on soil absorption, usable reserve area, setbacks, and equipment access. |
| Pump-assisted or engineered field | $8,550-$23,550 | More likely where slope, elevation, groundwater, or lot size limits gravity distribution. |
| Full system redesign after field failure | $8,550-$32,100 | Triggered when tank, field, soil, or code requirements all need correction. |
