The City of Johannesburg bills on a stepped tariff, so a hidden leak does not raise your account proportionally. It pushes you into the higher bands.
That is why a modest leak can multiply a bill. Detection methods at Leak Detection Johannesburg.
Send your last three account readings and a meter photo with taps closed.

- Close everything and read the meter twice, 15 minutes apart. Movement confirms a leak.
- Dye-test every toilet. A passing flush valve is the most common single cause.
- Close the irrigation valve and re-read. Rules the garden in or out.
- Isolate the pool top-up and re-read.
- Isolate the house at the internal valve. If the meter still turns, the leak is in the buried mains run.
- Book detection for whatever is left.
Getting the Account Adjusted
There is no standing leak rebate in Johannesburg or the surrounding metros. Everything from the water meter into the property is billed to the owner, whether the water was used or lost, so an adjustment is something you have to ask for rather than something you are entitled to.
Repair the leak first, then log a formal query with your municipality attaching dated meter readings, the detection report and the repair invoice. It must investigate and give you a written outcome, normally within a month or two, but whether it adjusts the account is at its discretion. Where the leak is on the municipal side of the meter, or the meter itself is faulty, you should not be liable for the loss at all. Some household policies also cover the excess municipal charge from a sudden leak, so check yours before you write the money off.

Frequently Asked Questions
My bill tripled but nothing looks wrong. What is going on?
Almost certainly a hidden leak plus the stepped tariff. Extra volume is billed in the higher bands, so a leak that adds a moderate amount of water can add far more than that proportionally to the account.
Can I get the money back from the municipality?
Not as of right. There is no standing leak rebate in the Gauteng metros, and water lost on your side of the meter is billed to you.
Repair the leak, then log a formal query with dated meter readings, the detection report and the repair invoice. The municipality must investigate and answer in writing, but any adjustment is discretionary. If the leak was on the municipal side of the meter, or the meter was faulty, you should not be carrying the cost at all.
What is the most common cause of a high water bill?
A silently leaking toilet, by a wide margin. It costs very little to fix and is the first thing to check before booking anything more involved.
