Septic Inspections When Buying or Selling in DeSoto County
DeSoto County is one of the fastest-growing counties in Mississippi, and many buyers moving out from Memphis have never owned a septic system before.
Sewer or septic? Check first
Large parts of Southaven, Horn Lake and Olive Branch are on public sewer, but much of the county, including rural parts of Hernando, Nesbit, Lewisburg, Eudora and Love, is not. Some neighbourhoods on the edge of town mix both. Confirm with the seller and the utility which applies before you assume either way.
Why records matter in Mississippi
Mississippi ties new water service to an approved on-site system. Before a water meter is set for a new home, MSDH needs to have issued its approval. For an existing home, the most useful documents are the MSDH approval, the system design, and any service records for an advanced treatment unit. Ask the seller for them, and ask MSDH what is on file. Older homes may have little paperwork. That is common, not necessarily a red flag, but the inspection has to do more work.
What the inspector should look at
Opened and ideally pumped; sludge and scum measured; baffles, outlet and filter checked.
Walked for wet spots, odours and erosion. Loess gullies easily on slopes.
Aerator, pumps, alarm and any disinfection working; service records reviewed.
Added bedrooms, pools, outbuildings or driveways over the system.
Local red flags
- A wet or spongy field in a dry spell, which suggests effluent perched on fragipan
- Fresh fill or sod over the field, which can hide a problem
- A treatment unit that is switched off or has no service history
- A lot near the Coldwater River or in low ground near Walls that has flooded
Cost
Inspections commonly cost a few hundred dollars, plus pumping if it is included. For a system with a treatment unit, expect a slightly higher fee because there is more to test.
Inspection questions for DeSoto County buyers
Is a septic inspection required to buy a home in DeSoto County?
It is usually a buyer or lender choice rather than a universal requirement. Given the soils and the number of first-time septic owners here, it is a sensible step.
How do I find a property's septic records?
Ask the seller and contact the Mississippi State Department of Health, which handles on-site wastewater approvals in DeSoto County.
What is the Mississippi water meter rule?
In short, a new water connection generally requires MSDH approval of the on-site system first. Our water meter page explains it.
What should I do if the inspection finds a problem?
Get a repair quote from a certified installer and use it to negotiate a repair, a price reduction or a credit before closing.
A licensed site evaluator has to answer that with a soil test; nobody can tell from a map. Send us your address and we will pass it to a licensed local professional where one is available. Request a quote →
