The water smelled fine and looked clear. But the test results told a very different story.

A Linden family had been using their tap water without any filtration for years. Then Johannesburg's water quality started making headlines. They called us because they wanted peace of mind.

We collected samples from the kitchen tap and the garden borehole. The municipal tap water came back within SANS 241 limits, safe for drinking. The borehole water, which they had been using for the kids' paddling pool and occasionally to fill cooking pots during outages, showed elevated nitrates and total coliforms.

We installed an under-sink reverse osmosis unit for drinking water and a UV steriliser on the borehole line. Problem solved, and they finally knew exactly what was in their water. That is what professional water testing looks like: facts first, then the right solution.

What We Test

Every Water Source Has
Different Risks

Municipal tap water, borehole water, and stored tank water each need specific testing. We cover all three, and we treat what we find.

Municipal Tap Water Testing

Joburg's tap water is treated at the reservoir, but it travels through kilometres of ageing pipes to reach your home. Old internal plumbing, roof tanks, and corroded fittings can all affect what comes out of your tap. We test to SANS 241 standards so you know whether your tap water is safe.

  • Full SANS 241 drinking water panel
  • Bacteria and chemical analysis
  • Physical parameter testing
  • Clear results report
  • Treatment recommendations if needed

Borehole Water Testing

Borehole water is not treated by anyone. It comes straight from the ground, and ground conditions in Randburg vary from street to street. Testing is not optional. It is essential, especially if you are using borehole water for drinking, cooking, or bathing.

  • Borehole-specific contamination panel
  • E. coli and coliform testing
  • Nitrate and heavy metal screening
  • Iron and manganese levels
  • Annual monitoring available

Tank and Stored Water Testing

JoJo tanks, roof tanks, and underground reservoirs all need periodic testing. Standing water can develop bacterial growth, and tanks can pick up contaminants from roofing materials, bird droppings, or deteriorating tank walls.

  • JoJo tank water analysis
  • Roof tank contamination check
  • Bacterial growth screening
  • Sediment and turbidity testing
  • Tank cleaning recommendations

Laboratory Analysis

SANS 241 Certified
Lab Testing

We use SANAS-accredited laboratories only. Your results meet the South African drinking water standard and carry weight for property transactions, insurance, and health investigations. Not a DIY strip test, real lab certification.

The laboratory analyses over 20 parameters including E. coli, total coliforms, nitrates, iron, manganese, pH, turbidity, total dissolved solids, and heavy metals. Every result comes with a clear pass/fail indicator against SANS 241 limits.

Results typically arrive within 5 to 7 working days. We explain everything in plain English, no confusing lab jargon.

The Process

How Water Testing
Actually Works

From sample collection to a clear action plan, the process is straightforward. We handle the logistics so you get reliable results without the hassle.

1

Sample Collection

We visit your property and collect water samples following strict laboratory protocols. Samples are taken from the specific water source you want tested: kitchen tap, borehole outlet, JoJo tank, or all of the above. Proper collection technique ensures accurate results.

2

SANAS Laboratory Analysis

Your samples go to a SANAS-accredited laboratory for full SANS 241 analysis. Results typically arrive within 5 to 7 working days. Every parameter that matters for drinking water safety is covered.

Report and Action Plan

We explain your results in plain English. No confusing lab jargon. If treatment is needed, we recommend exactly what to install, and then we install it. From test to treatment, one company handles everything.

Test and Treat

We Test It.
We Fix It.

Most companies either test water or treat it. We do both. That means you get honest results and the right solution, from the same team. No middleman, no upselling.

If your results show a problem, we install the right solution: under-sink filters, whole-house systems, UV sterilisers, or reverse osmosis. The treatment is matched to your specific test results, not a generic package.

We also work across the broader water services spectrum, from filtration and purification to complete borehole systems.

Test and Treat

Labs test water. Filter companies sell filters. We do both. If your results show a problem, we install the right solution. No middleman, no guesswork.

Every Source Covered

Municipal tap, borehole, JoJo tank, roof tank. We test all of them. Many Randburg homes use multiple water sources, and each needs separate testing.

SANS 241 Certified

SANAS-accredited laboratories only. Legally recognised results valid for property sales, insurance, and health investigations. Not a DIY strip test.

Local Knowledge

Decades in Randburg means we know which suburbs have older pipe infrastructure, which areas have borehole water quality concerns, and what to test for based on your location.

Water Quality Across
Randburg Suburbs

Water quality in Randburg is not uniform. Fairland's older homes often have galvanised steel internal plumbing that adds iron and sometimes lead to otherwise safe municipal water. Northcliff properties on the ridge may have lower municipal pressure, leading homeowners to install storage tanks that can develop bacterial issues if not maintained.

Linden and Parkhurst have a mix of old and renovated properties where the plumbing age varies enormously. And with hundreds of boreholes drilled across Randburg in recent years, untested borehole water is a growing concern.

We regularly work in Fairland, Northcliff, Linden, Parkhurst, Blairgowrie, Bordeaux, Greenside, and Ferndale. If you are unsure about your water quality, testing is the fastest way to get a definitive answer.

Common Questions

Water Testing FAQ

In most cases, yes. Joburg Water treats municipal supply to SANS 241 standards at the reservoir. However, the water travels through old infrastructure and your home's internal plumbing before reaching your glass. Old galvanised pipes, corroded fittings, and roof tanks can introduce contaminants. If you are unsure, testing is the only way to know for certain.

SANS 241 testing is done by a SANAS-accredited laboratory with professional equipment. It covers dozens of parameters and gives you legally recognised results. DIY test kits check a few basic parameters with limited accuracy. For drinking water safety, professional testing is the only reliable option.

Testing costs depend on which parameters you need analysed. A basic screen differs from a comprehensive SANS 241 panel. Contact us to discuss your water testing needs and we will provide clear pricing.

Test immediately if you notice changes in taste, colour, or smell. Test annually if you use borehole or tank water. Test before installing a filtration system so you buy the right one. Test after any nearby construction, flooding, or sewage event. Test when buying or selling a property with a borehole.

We recommend a specific treatment solution based on your results. Bacteria issues need UV sterilisation. Chemical contaminants may need activated carbon or reverse osmosis. Iron and manganese need specialised filters. We explain the options, give you a quote, and install the system. One call, complete solution.

Both. While municipal water is treated at the reservoir, it travels through kilometres of ageing infrastructure and your home's internal plumbing. Old galvanised pipes, roof tanks, and corroded fittings can introduce contaminants after treatment. Testing confirms what is actually coming out of your tap, not what left the reservoir.

SANAS-accredited laboratory results typically take 5 to 7 working days. We explain the results in plain English and recommend treatment if anything is outside safe limits.

Yes. JoJo tanks, roof tanks, and underground reservoirs all need periodic testing. Standing water can develop bacterial growth, and tanks can pick up contaminants from roofing materials, bird droppings, or deteriorating tank walls. We test all stored water sources.
