Surprise at 4 Meters – Snakes Spotted in a Shallow Borehole!

When we lower a downhole camera into a well, we expect to see familiar features—maybe some sediment buildup, biofilm on the casing, or the occasional aquatic insect drifting past the lens. But during a recent routine inspection of a shallow well, we got more than we bargained for. At just 4 meters below the surface, the camera revealed something entirely unexpected: live snakes moving through the water.

Yes—snakes. Slender, sinuous, unmistakably alive.

What We Saw

The well is relatively shallow, with the water level only a few meters down. As the camera descended past the casing and into the water column, we noticed movement that at first looked like waving plant roots or debris drifting in the current. But a closer look revealed smooth, coordinated motion—heads, bodies, and tails weaving through the water. These weren’t worms or eels; they were clearly snakes, navigating their way through the confined space of the well.

How Did They Get There?

There are a few possible explanations:

• Access from the top: If the wellhead is poorly sealed or left open, it becomes easy for small animals to enter—especially snakes, which are skilled climbers and explorers.

• Surface flooding: During heavy rains or flood events, surface water can carry wildlife—including snakes—into open or improperly protected bores.

• Habitat seeking: Some aquatic or semi-aquatic snakes may be drawn to wells because of the consistent moisture, cooler temperature, and presence of small prey like frogs or insects.

• 
  

Are They Dangerous?

We would always start by assuming they are dangerous ! The snakes in question appeared to be large in size—most likely looking for shelter or food.

However, their presence in a water source used for irrigation or livestock is still a cause for concern. Apart from the shock factor, animals in a well can compromise water quality through contamination or even blockages in the pump or intake.

What This Tells Us

This surprising encounter is a reminder of just how important wellhead protection really is. A properly constructed and sealed well should include:

• A secure, animal-proof cap

• A concrete pad or apron to direct surface water away

• A vent with a screen to prevent wildlife entry

• Regular inspections, especially after storms or during the dry season

Final Thoughts

While it’s not every day you find snakes in a borehole, this unusual incident highlights how nature can find its way into the most unexpected places. The footage might raise a few eyebrows (and pulses), but it also serves as a useful teaching moment: your well is only as clean and secure as its weakest point.

If you’re not sure about the condition of your wellhead—or just want to rule out any slithery surprises—it might be time to book a camera inspection of your own. You never know what might be lurking just a few meters down. 🐍📹💧
