Quick rule
Sewer connects your building to a municipal or private sanitary main. Septic treats wastewater on the lot with a tank and drain field when no sewer is available.
When septic makes sense
- Rural or fringe lots without a sewer main
- County health design and permits in place
- Soil and setbacks allow a field
When sewer makes sense
- Main is in the street or easement and connection is required or available
- You need a lateral, cleanouts, and possible ROW work
