Get Water COC QuotesWhat Is the Water Installation Certificate?
The City of Cape Town Water By-law says the seller must, before transfer, submit a certificate of compliance from a registered plumber. It certifies that the water installation conforms to the National Building Regulations and the By-law, on the items listed on the City's form. It is a Cape Town requirement, separate from the national electrical COC.
What the Plumber Checks
Items on the City's checklist include:
| Checklist item | What it means |
|---|---|
| Water meter | Registers when a tap is open and stops completely when no water is used |
| Leaks | No terminal water fittings leak and they are properly fixed in position |
| Hot water cylinder | Geyser installed to SANS 10252 and SANS 10254, including its valves, drip tray and overflow |
| Stormwater | No stormwater discharges into the sewer system |
| Cross-connections | No connection between the drinking water supply and a greywater, rainwater or borehole system |
| Pipework | Water pipes properly saddled and secured |
What it does not cover. The City states the certificate cannot be used as a quality control document for anything beyond the checklist. Blocked drains, low pressure, water quality, irrigation and pool systems are not certified. Check the current form with your plumber, as the City updates it from time to time.
Stormwater and geyser issues are the usual failures. Get quotes early so repairs do not hold up transfer.
Request an Inspection QuoteCommon Reasons a Property Fails
- Stormwater into the sewer. Downpipes or yard gullies connected to the sewer. Very common in older Cape Town homes.
- Geyser non-compliance. Missing vacuum breakers, drip tray, overflow or a faulty pressure control valve.
- Leaking taps and toilets. Including cisterns that run into the pan.
- Meter that keeps turning. Usually a hidden leak.
- Borehole, wellpoint or greywater systems connected to the municipal supply without proper separation. Common in Constantia, Durbanville and Table View gardens.
What Happens If It Fails?
The plumber lists what must be fixed and quotes for it. Once the repairs are done, the certificate is issued. The inspection fee and the repair cost are separate, and you may get repair quotes from other plumbers.

The water certificate is one of the Cape Town-specific property compliance certificates. Your conveyancer submits it to the City before transfer. Book the plumber once the sale agreement is signed, so there is time for repairs.
How Long Does It Take?
The inspection of a typical house takes an hour or two. Repairs, if needed, add time before the certificate can be issued.
Water COC Questions
Is a water certificate required in Cape Town when I sell?
Yes. Section 14 of the City of Cape Town Water By-law requires the seller to submit a certificate of compliance from a registered plumber before transfer.
Is the water certificate the same as a plumbing COC?
People use both names. In Cape Town it means the City's Certificate of Compliance of Water Installation, issued on transfer of ownership.
Who can issue it?
A plumber registered with the City of Cape Town under the Water By-law.
Does it mean all the plumbing is in good condition?
No. It confirms the items on the City's checklist. It does not certify drains, water pressure or the general condition of the plumbing.
Who sends it to the City?
Usually the conveyancer, on the seller's behalf, before transfer.
Do I need it outside Cape Town?
This requirement is specific to the City of Cape Town. Other municipalities have their own rules.
