I own a 1 acre property with an existing 3 bedroom home on it. I'd like to build a separate structure (two car garage with a small 700 square foot, 1 bedroom apartment above it) and am wondering what my septic system options are:
1. Is it possible to just hook into the existing septic system? The tank would be about 120 feet away from the structure, so I'm guessing I'd need a pump. Is it even feasible?
2. If I have to install a separate tank for the detached structure, can I hook it up to the existing drainfield? The drainfield sits roughly between the two buildings.
3. Since it's a one bedroom apartment, are there cheaper options for dealing with septic waste than building a full two bedroom septic system (e.g., are there smaller, or self-contained above ground solutions that might work)?
Thanks in advance for any guidance you can provide!
