Do You Need Permission to Drill a Borehole in Johannesburg?

Drilling a borehole feels like a straightforward decision — your municipal supply is unreliable, you want a backup, and you have the space. The regulatory side, however, catches many Johannesburg homeowners off guard. Groundwater in South Africa is a public resource governed by the National Water Act (Act 36 of 1998), which means you do not automatically own the water beneath your property. Understanding what permission you need — and who is responsible for getting it — is essential before a drill rig arrives on your lawn.

Who regulates borehole drilling in Johannesburg?

Regulation comes from two directions. The Department of Water and Sanitation (DWS) governs groundwater use at a national level under the National Water Act. Johannesburg Water, a municipal entity, manages the local water network and has an interest in how private abstraction affects the broader system. For the purposes of drilling and using a borehole, DWS is the primary authority you deal with. Johannesburg municipality may also have by-laws covering aspects such as connecting a borehole to your household plumbing or irrigating from it, so it is worth checking with the City of Johannesburg directly for anything structure- or connection-related.

The difference between registration and authorisation

These two terms are often used interchangeably, but they mean different things under the National Water Act.

Registration is a relatively simple administrative step. If your water use falls within what the Act calls a Schedule 1 or General Authorisation allowance — broadly, domestic use and small-scale garden irrigation — you are typically not required to hold a full water-use licence, but you may still be required to register your borehole with DWS. Registration records the existence of the borehole, its location, and the intended volume of abstraction.

A water-use licence is a more involved process required when intended use exceeds the thresholds set out in the General Authorisations published under the National Water Act. Commercial irrigation, supplying water to multiple properties, or abstracting volumes above the stated thresholds are the scenarios most likely to trigger a licence requirement.

As a rough guide, a typical household borehole used for garden irrigation and non-potable domestic purposes at modest volumes is more likely to fall under registration than full licensing — but this depends on your specific volumes and the aquifer you are drawing from. Confirm the applicable threshold with a registered drilling contractor or directly with DWS before assuming you are exempt.

Scenario	Likely requirement
Domestic use, garden irrigation, low volume	Registration (General Authorisation)
Higher abstraction volumes or commercial use	Water-use licence application
Supplying neighbouring properties	Water-use licence almost certainly required
Borehole used only for geothermal or monitoring	Separate DWS guidance applies

This table is a simplified guide only. DWS determinations depend on volumes, aquifer type, and water management area — get a professional assessment.

What your installer should do — and what remains your responsibility

A reputable, registered borehole drilling contractor should be able to explain the registration process and assist you with the paperwork. Some will handle the DWS submission on your behalf as part of their service. What they cannot do is transfer the legal obligation to you — as the property owner, you are the water user of record, and any penalties for unlicensed or unregistered use sit with you.

Before appointing anyone, ask specifically:

• Are you registered with the DWS as a driller?
• Will you assist with or complete the borehole registration?
• What volumes are you proposing to equip the pump for, and does that affect my authorisation category?

Water quality and SANS 241

Permission to drill and permission to drink are separate matters. Even if your borehole is correctly registered, groundwater in Johannesburg can contain elevated mineral levels, bacteria, or other contaminants — particularly in areas with historical mining activity or agricultural land use. The relevant quality benchmark is SANS 241 (2024 edition), the South African drinking-water quality standard published by the South African Bureau of Standards.

Before using borehole water for any potable purpose — drinking, cooking, filling a kettle — have it tested by an accredited laboratory against SANS 241 parameters. Test first, treat second. A registered installer can advise on appropriate filtration or treatment, but the test result is what determines what treatment (if any) is actually required. Do not assume borehole water is safe to drink simply because it is clear.

Does Johannesburg Water need to be notified?

If you intend to use your borehole water inside the house — for toilets, washing machines, or any connection to your household plumbing — Johannesburg Water’s by-laws typically require that you notify them and ensure a proper backflow prevention device is installed to protect the municipal supply. Cross-connecting an untreated private supply to the municipal network is a health risk and is prohibited. Check the current requirements directly with Johannesburg Water or the City of Johannesburg, as by-law details can change.

Practical steps before you drill

Pulling together the regulatory and practical requirements, here is a sensible order of operations for a Johannesburg homeowner:

1. Check your intended use. Purely outdoor, non-potable irrigation is simpler to authorise than potable household use.
2. Engage a registered driller early. Ask about registration requirements before signing anything.
3. Confirm with DWS. The Department of Water and Sanitation’s website (dws.gov.za) publishes the General Authorisation regulations and registration guidance. If in doubt, contact their regional office directly.
4. Check municipal requirements. The City of Johannesburg or Johannesburg Water may have additional by-law obligations around connections and backflow prevention.
5. Test the water before any potable use. Use an accredited laboratory and compare results against SANS 241.
6. Keep records. Retain your registration documents, drilling logs, and water test results. These are useful if you sell the property and may be required by DWS or your insurer.

The process is manageable for most residential projects. The key is not to treat regulation as an afterthought — it is considerably easier to register correctly from the start than to retrospectively authorise an existing borehole.
