Understanding Gauteng’s Borehole Laws: Registration, Water Use Limits, and Compliance
Borehole Regulations: With Gauteng facing increasing water shortages, many homeowners are turning to boreholes as an alternative water source. However, drilling a borehole is not as simple as setting up a well and using unlimited water. Strict regulations govern borehole use in South Africa, and failing to comply can lead to legal consequences.
Boreholes Are Not a Free-for-All
According to environmental scientist Ayesha Laher, many homeowners are unaware that borehole use is regulated by national legislation. The Department of Water and Sanitation (DWS) is responsible for overseeing all groundwater usage, and the National Water Act specifies how much water can be extracted before requiring a license.
“It’s not free, and you cannot use as much as you like,” Laher explained. “If you extract more than the allowable limit, you must apply for a license. Otherwise, it’s considered illegal water use.”
Bylaws Require Borehole Registration
Municipal bylaws in Gauteng require that all boreholes be registered. Homeowners must ensure that their borehole complies with SANS 10299, a national standard that regulates drilling practices and water extraction limits. This includes conducting a recharge test to determine how much water can safely be drawn from the aquifer.
Many residents are unaware that certain areas in Gauteng, such as Centurion, are classified as dolomitic zones, where borehole drilling is prohibited. Drilling in such areas can lead to sinkholes, posing a major safety hazard.
The Risk of Unregulated Boreholes
Recent cases have shown the dangers of illegal borehole drilling. Some boreholes have caused structural damage to underground infrastructure, including the Gautrain tunnel, which was recently declared unsafe due to borehole drilling in the area.
Experts warn that drilling without approval can lead to severe consequences, including collapsing tunnels, water contamination, and environmental degradation. Laher emphasized that without proper registration, residents could be held liable for damages caused by illegal borehole use.
Water Crisis in Gauteng: Why Borehole Use Is Under Scrutiny
The borehole regulations come at a time when Gauteng is experiencing a severe water crisis. Tshwane Mayor Nasiphi Moya recently urged residents to use water sparingly, warning that water consumption had exceeded sustainable levels.
Rand Water reported that in January 2025, Tshwane residents consumed over 752 megalitres (ML) of water per day, with a peak of 853ML per day recorded on February 3. This excessive usage has put additional strain on reservoirs across Gauteng, leading to water restrictions and supply disruptions.
Several reservoirs in Tshwane, including Akasia Park, Koedoesnek, The Reeds, and Wonderboom, have been identified as the highest consumers of water. Meanwhile, Joburg Water has reported that multiple reservoirs across Johannesburg are experiencing low water levels, causing supply shortages in areas such as Crosby, Brixton, Lenasia, and Parktown.
Key Takeaways for Homeowners Considering a Borehole
- Register Your Borehole – All boreholes must be registered with the local municipality to ensure compliance with water regulations.
- Know Your Limits – Exceeding the allowable extraction limit requires a water license from the Department of Water and Sanitation.
- Follow SANS 10299 Standards – Borehole drilling must meet national safety and environmental guidelines.
- Check Your Area’s Geology – Avoid drilling in dolomitic areas like Centurion, which can lead to sinkholes.
- Be Aware of Water Restrictions – With Gauteng facing a water crisis, responsible water use is crucial to avoid further shortages.
Final Thoughts
While boreholes can provide an alternative water source, they must be drilled and used responsibly. Homeowners should familiarize themselves with the National Water Act, municipal bylaws, and borehole registration requirements to ensure compliance. Failing to follow these regulations not only risks legal penalties but also contributes to Gauteng’s growing water crisis.
Before drilling, ensure that you register your borehole, comply with extraction limits, and avoid drilling in restricted areas to prevent environmental hazards and infrastructure damage.
