As Buyers are on the search for a new home, a common question is about the wastewater: Is this house on septic or sewer, and does it matter? There are pros and cons to each, and there are people who prefer either (or don't care either way). Here's what you need to know:

A septic system is comprised of tank(s) and a drain field on the property where wastewater passes through and is collected.

  • Require a bit of physical land space, so it's most common to see them on lots greater than 0.25 acre.
  • You cannot put anything heavy on top of the septic system (the tanks, lines, or drain field), so if you want to install a pool, pour a concrete pad, etc it is critical that you know the location of your system and plan accordingly.
  • The cost for a septic system is predominately paid up-front at installation.
  • Maintenance: It is advised to have your septic tank pumped every 3-5 years. (Costs $400-$500 to pump & it stinks!)
  • Can be more prone to clogging/issues, and you need to be careful what you flush down drains (no grease for sure!)

Sewer systems are a network of pipes that deliver wastewater to a treatment facility.

  • Not available everywhere- must have the connections to the sewer system available.
  • Sewer lines are predominantly in the front yard (from the house to the street), so it is uncommon to have to work around sewer lines in your back yard if you are considering a pool, RV parking, etc.
  • There is a monthly cost associated with sewer, most often an add-on to your water bill.
  • There is very little maintenance, though you want to keep your drain lines clear.
  • While they may not be prone to clogging, issues with a sewer line can be costly to repair.

So the big question: Does one of these systems increase the value of your property?

NOPE! No price difference in the housing market for septic vs. sewer. Though, as stated, there can be Buyer preferences at play. Though I've had Buyers strongly on both sides of the fence regarding which they prefer.

Regardless, you'll want to ensure your wastewater system is working properly, and if there are known issues, you will need to disclose these to a potential Buyer on your Seller's Property Disclosure.
