The City of Cape Town 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 Cape Town.

- 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.
The City Rebate
Cape Town allows a rebate application for undetected underground leaks. It normally covers up to about three months of billing, is limited to one claim per property, splits the cost of the wasted water, and may require a water management device to be fitted. Convenience fixtures such as pools and irrigation are excluded. Apply as soon as the repair is done.

Keep everything dated: meter photographs, the detection report and the repair invoice. A rebate application is assessed on evidence, and the sequence of dates is what supports it.

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 City?
You can apply for a rebate on undetected underground leaks. It typically covers up to three months of billing, allows one claim per property, and shares the cost of the wasted water. Pool, irrigation and other convenience-fixture leaks are excluded.
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.
