Why is My Borehole Water Brown? Nakiso Borehole Drilling Explains

Discovering brown water coming from your borehole can be alarming. It's a clear sign that something isn't right, and understanding the cause is crucial for ensuring the safety and quality of your water supply. At Nakiso Borehole Drilling, we've encountered this issue numerous times, and we're here to shed light on the common reasons behind brown borehole water.



Common Culprits Behind Brown Borehole Water:

  • Iron and Manganese:
    • These are the most frequent culprits. Iron and manganese are naturally occurring minerals found in soil and rock formations.1 When groundwater comes into contact with these minerals, they dissolve and can cause discoloration.
    • Iron typically imparts a reddish-brown or rusty hue, while manganese can result in a darker brown or even black appearance.2
    • These minerals can also cause staining on plumbing fixtures and laundry.3
  • Sediment and Clay:
    • If your borehole was recently drilled or if there's been a disturbance in the surrounding soil, sediment and clay particles can enter the water supply.
    • This can lead to a cloudy or muddy brown appearance.
    • Also, if the borehole casing has been compromised, or if the screen at the bottom of the borehole has been damaged, then sediment can enter the water.4
  • Tannins:
    • Tannins can leach into groundwater in areas with abundant vegetation or organic matter.5
    • Tannins are natural organic compounds that can cause a yellowish-brown or tea-colored tint to the water.6
    • These are more common in areas with many trees, or swamps.
  • Decaying Organic Matter:
    • Decomposing plant or animal matter can contaminate the groundwater, leading to discoloration and potential bacterial growth.7
    • This is less common in properly constructed boreholes but can happen if surface water enters the borehole.
  • Corrosion:
    • If your borehole casing, pipes, or pump are corroding, rust particles can enter the water, causing a brown discoloration.8
    • Older boreholes are more susceptible to this issue.

What Should You Do?

If you're experiencing brown borehole water, it's essential to take the following steps:

  • Avoid Consuming the Water: Until you've determined the cause and resolved the issue, refrain from drinking or cooking with the discolored water.
  • Contact Nakiso Borehole Drilling: Our experienced team can assess your borehole and water quality to identify the source of the problem. We offer comprehensive water testing and filtration solutions.
  • Water Testing: A professional water test is crucial to determine the specific contaminants present in your water.9 This will help us recommend the appropriate treatment options.
  • Filtration and Treatment: Depending on the cause of the discoloration, we can recommend and install suitable filtration systems, such as iron removal filters, sediment filters, or water softeners.
  • Borehole Inspection: We can also conduct a thorough inspection of your borehole to identify any structural issues or potential sources of contamination.

Fact 1: Know Your Borehole Casings

The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)

This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.

Fact 2: Borehole Drilling Depth

The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).

Fact 3: There Is No 100% Guarantee

It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.

Fact 4: Siting Is Important
Fact 5: Know The Risks
