Buying a home with a well and septic system?
It is not a bad thing at all.
But it is different from buying a home connected to public water and sewer, and there are a few extra things buyers should understand before closing.
Let’s break it down.
SEPTIC SYSTEM
A septic system handles the home’s wastewater on the property instead of sending it to a public sewer system.
One of the first things I want to verify is the septic permit.
Why?
Because the septic permit can determine how many bedrooms the property is legally designed to support.
A home may physically have four rooms being used as bedrooms, but if the septic permit is only approved for three bedrooms, that matters.
North Carolina brokers are expected to verify septic information and not simply rely on an old MLS listing.
During due diligence, I generally recommend having the septic system professionally evaluated.
Depending on the property and system, the inspection may include things like:
Tank condition
Liquid levels
Inlet and outlet components
Baffles
Drain field condition
Signs of sewage backup or failure
Location of the tank and drain field
Any obvious drainage or saturation concerns
If the ground around the septic area is unusually wet or smells like sewage, that is definitely something to investigate further.
And here is another thing buyers sometimes overlook:
Know where the septic system and drain field are located.
You do not want to plan a future pool, garage, addition, driveway, or other improvement over an area that needs to remain available for the septic system.
WELL WATER
A private well means the property has its own water source rather than being connected to municipal water.
That also means the homeowner becomes responsible for maintaining that water source.
I recommend testing the well water during due diligence.
Water testing can look for concerns such as bacteria and other contaminants, and North Carolina allows private well sampling through local health departments.
Depending on the property, buyers may also want to evaluate:
Water pressure
Well pump operation
Well depth and available records
Condition of the well head
Location of the well
Distance from the septic system
Water quality
Flow or yield concerns
Any treatment or filtration system
And yes, the water can look perfectly clear and still have something in it that you cannot see.
That is why testing matters.
WHAT IS DIFFERENT FROM CITY WATER AND SEWER?
With public utilities, you typically receive a monthly water and sewer bill and the municipality maintains the larger infrastructure.
With well and septic, you generally do not have a monthly municipal water and sewer bill, but you are responsible for maintaining your own systems.
That means planning for things like:
Septic pumping
Septic repairs
Well pump replacement
Water filtration
Water testing
Drain field maintenance
Unexpected repairs
So instead of paying the city every month, you need to think more long-term about maintenance.
WHAT SHOULD A BUYER CHECK?
Before closing on a well and septic property, I want my buyers asking:
Is there a septic permit?
How many bedrooms is the septic system approved for?
Where are the tank and drain field?
When was the septic system last serviced or pumped?
Has the septic system been inspected?
Has the well water been tested?
Are there any water-pressure concerns?
Are there treatment or filtration systems?
Are there records for the well?
Are there any signs of drainage, moisture, sewage odor, or contamination?
The due diligence period is exactly when buyers should investigate these kinds of property issues. North Carolina specifically identifies septic inspections as one of the common due diligence investigations buyers may choose to complete.
One more thing.
A well and septic home can be a fantastic property.
I just do not want a buyer discovering after closing that the “four-bedroom house” has a three-bedroom septic permit or that the well needs thousands of dollars of work.
That is why we investigate first.
Buying the house is exciting.
Understanding what you are buying is even more important.
