Multifamily - Septic

Devon Moore

Hi!

I am currently looking at a duplex in New Hampshire with a septic system. I like the property because it has a great potential to add a second 1 bedroom unit. One unit is a 3 bedroom house with two bathrooms. The second unit is a 1-bedroom apartment with one bathroom. The septic tank is 2,500 gallons. Would this be a sufficient size to add another 1bed/1bath apartment to?

Thanks for any insight!

Devon

The tank size doesnt matter as much as the perk rate of the soil .  10 gallons goes in and it displaces 10 gallons into the drain field . The tank holds the solids to allow them to settle and break down .
