Borehole Water and Municipal Bylaws in Joburg

Drilling a borehole in Johannesburg is entirely legal and increasingly practical, given that Johannesburg Water’s own audited figures show non-revenue water running at 44.8% — a clear sign the reticulation system is under stress. But legal does not mean unregulated. Before the drill rig arrives, and certainly before you connect a single tap to groundwater, there is a layered set of rules to understand: national water law, City of Johannesburg bylaws, and drinking-water quality requirements. This article walks through each layer plainly.

The national framework that sits above everything else

Borehole regulation in South Africa starts at national level, not municipal level. The National Water Act (Act 36 of 1998) is the governing legislation. It establishes that groundwater is a national resource — you own the land, but not the water beneath it. The Department of Water and Sanitation (DWS) administers this Act and requires that boreholes be registered and, depending on the volume you intend to abstract, licensed.

For most residential properties in Johannesburg, abstraction for household use falls within what the Act calls a Schedule 1 General Use — a basic human need allocation that does not require a formal licence. However, registration is still compulsory. You can find the step-by-step process explained in the post on borehole registration with DWS, which covers the forms, timelines, and what happens if you skip it.

The short version: registering is not optional, and the DWS has the authority to order an unregistered borehole to be decommissioned.

What the City of Johannesburg’s bylaws add

On top of national law, the City of Johannesburg has its own Water Services Bylaws. These are made under the Water Services Act (Act 108 of 1997) and enforced locally. The bylaws deal primarily with how borehole water interacts with the municipal reticulation system — and the core rule is straightforward: cross-connections are prohibited.

A cross-connection means any physical link between your borehole supply and the municipal supply pipe. The city’s concern is contamination risk to the wider network. If borehole water somehow back-siphons into the municipal main, it could compromise supply to neighbours. The solution is a complete separation of the two systems, enforced by an air gap or an approved backflow preventer. Many installers will specify this automatically; if yours does not mention it, ask directly.

Other points the bylaws typically address:

• Drainage of surplus water. If you discharge borehole water into a municipal stormwater or sewer drain, that may require prior approval. Discharging large volumes without approval can attract a fine.
• Irrigation use. Borehole water used for garden irrigation is generally permitted, but during formal water restrictions the city may extend those restrictions to borehole use as well. Check the current restriction schedule on the Joburg website before assuming borehole water is restriction-free.
• Signage. Some municipalities require visible signage at points where borehole water is used — for example, at garden taps — to indicate the water is not for drinking unless treated. Confirm whether this applies in your suburb.

Drinking-water quality and SANS 241

This is where homeowners sometimes make a dangerous assumption: that borehole water is automatically safe to drink because it comes from the ground. It is not — not without testing.

SANS 241 (2024 edition) is the South African National Standard for drinking-water quality. If you intend to use borehole water at any point where it could be consumed — including brushing teeth, cooking, or ice — your water must meet SANS 241 limits. These cover microbiological contamination, chemical parameters, and aesthetic factors.

The principle here is straightforward: test first, treat second. A basic water quality test from an accredited laboratory will tell you what, if anything, is present. Treatment options — UV sterilisation, reverse osmosis, chlorination — depend entirely on what the test reveals. Never install treatment without knowing your actual water chemistry; you could treat for the wrong contaminant or create a false sense of safety.

For domestic borehole systems, testing once or twice a year is a sensible baseline, and after any period of heavy rain (when surface contamination risk rises).

Planning permission and building regulations

A borehole is not typically classified as a building structure, so you do not usually need a building plan approved by the city before drilling. That said, a few practical points apply:

• Servitude and boundary setbacks. You need to confirm the position of any municipal servitudes on your title deed before choosing a drill site. Drilling through a servitude without authorisation can result in costly remediation.
• Electrical installation. The pump and pressure system will require an electrical connection. Any new electrical work must be done by a registered electrician and a Certificate of Compliance (CoC) issued under the Occupational Health and Safety Act. This is a building-regulation requirement, not just good practice.
• Homeowners’ association rules. If your property is in an estate or complex with an HOA or body corporate, check their rules. Some developments have restrictions on borehole drilling — either prohibiting it outright or requiring prior approval from the trustees.

For a broader overview of the full system — from drilling depths to pump selection and system costs — the borehole drilling guide covers the technical side in detail.

Costs you should budget for compliance

Compliance is not free, but the costs are manageable when planned for upfront. As a rough guide only — confirm actual figures with your installer and the relevant authorities:

Compliance item	Typical cost range
DWS registration (government fee)	Low or nil for residential use — confirm with DWS
Water quality testing (accredited lab)	Typically a few hundred to low thousands of rands per test
Backflow preventer / air-gap installation	Often included in a full system install; confirm with installer
Electrical CoC	Typically included in the electrician’s quote for the pump installation
Full borehole system (drilling, casing, pump, plumbing)	R60,000–R100,000 for most Joburg residential installs; range is R40,000–R150,000

These are indicative figures only. Get written quotes from at least two or three installers to compare line items, and ask each one explicitly what compliance steps they include in their scope.

If you want side-by-side quotes that break out the compliance costs clearly, request quotes from vetted local drillers — free, and no commitment required.

What to do before you drill: a plain checklist

Rather than a guarantee of compliance — which depends on your specific property, water use, and the current state of bylaws — think of this as a starting-point checklist to discuss with your installer and, where necessary, the city or DWS:

1. Check your title deed for servitudes and confirm your intended drill site avoids them.
2. Contact DWS (or your installer, who should handle this) to confirm registration requirements for your intended abstraction volume.
3. Verify HOA rules if applicable.
4. Ensure complete separation of borehole and municipal systems — no cross-connections.
5. Commission a water quality test before using the water for any domestic purpose.
6. Get an electrical CoC for the pump installation.
7. Check current water restrictions on the Joburg city website to understand whether borehole irrigation may be affected.

Johannesburg’s groundwater resource is real and useful. The rules around it exist primarily to protect that resource and the wider water network — not to obstruct homeowners. Working within them from the start is considerably cheaper than fixing problems after the fact.
