A three- or four-bedroom home without a grinder needs at least 1,000 gallons. Five bedrooms need 1,250 gallons. Check the permit; these are legal minimums, not a measured local average.

|---|---|
| 1–4 bedrooms; no grinder | 1,000 gallons |
| 5 bedrooms; no grinder | 1,250 gallons |
| 6 bedrooms; no grinder | 1,500 gallons |

Only if the soil and approved design support it. Some sites need another treatment or distribution method.
