Conveyancing certificate

A conveyancing certificate, also known as a Section 66 certificate, identifies outstanding property charges. The selling agent and your conveyancer use the information on the certificate to allocate outstanding charges between the current and new owner.

How to get it

Ask one of our Property Link brokers to apply for you – they'll charge for the certificate and add their agent fee. You can find out how much a certificate will cost at prices for other services.


Service location print 

A service location print shows:

  • our pipes and structures on a property
  • the property's point of connection to our wastewater (sewer) system.

Selling agents and conveyancers use the diagram to provide information about our pipes. The information it provides helps you check:

  • if the property has a point of connection to our wastewater system
  • where the point of connection to our wastewater system is (it may be on another property)
  • where our pipes are located
  • how close the existing building is to our pipes
  • if you need to find out if we gave approval for the building.
How to get it

Apply at Sydney Water Tap in. Alternatively, ask one of our Property Link brokers to apply for you – they'll charge for the print and add their agent fee. You can find out how much a print will cost at prices for other services.


Sewer service diagram

A sewer service diagram shows the private wastewater (sewer) pipes on a property. Buildings and pipes are shown, but not pools.

Selling agents and conveyancers use this diagram to check if:

  • the plumbing work on a property has been inspected
  • there are any private pipes crossing the property.

Plumbers also use them so they can clear blockages or change pipes.

NSW Fair Trading has inspected private plumbing work since 2012. Before 2012, Sydney Water inspected private plumbing. 

How to get it

Ask one of our Property Link brokers to apply for you – they'll charge for the diagram and add their agent fee. You can find out how much a diagram will cost at prices for other services.

Most diagrams only take a minute to come through. However, if we need to investigate something on a diagram, it may take up to 7 days.  

Tips on how to read your diagram
  • To find out what a symbol means on a diagram, download Help with your sewer service diagram (383KB).
  • If there's plumbing that's not on the diagram, it may not have been inspected. To check, call us on 13 20 92.
  • Is your diagram old? If it shows the plumbing the way it is, it's fine. If not, call us on 13 20 92 and we'll look into it for you.

We provide diagrams and prints so you can locate our pipes, the private sewer pipes on your property and your point of connection to our wastewater system.


Building over sewer letter

A building over sewer letter tells you if we approved a building close to, or over, our wastewater pipes. Selling agents and conveyancers use the letter to determine if a building on a property has been built with our approval. We must approve all buildings and structures that need approval from council or a private certifier.

If you're building over or next to assets, you need to understand our requirements. These are to ensure you don't damage our pipes and structures, and we have ongoing access to maintain them.

How to get it

Ask one of our Property Link brokers to apply for you – they'll charge for the letter and add their agent fee. You can find out how much a letter will cost at prices for other services.


Special meter reading

You may need to ask us to read a meter earlier than usual if you're selling or leasing a property. We can read the meter and send a bill based on the special meter reading.

Selling agents and conveyancers use meter reading information before the sale of a property is finalised to calculate water use since the last meter reading. 

How to get it

Ask one of our Property Link brokers to apply for you – they'll charge for the reading and add their agent fee.  You can find out how much a reading will cost at prices for other services.


Section 88G certificate

A Section 88G certificate identifies any charges billed to the property owner that aren't covered by the normal charges shown on the bill. This debt isn't transferred to the new owner when the property is sold. Selling agents and conveyancers use this information to determine if the owner has any debts to us that aren't shown on normal bills.

If we've incurred costs that should be paid by the owner, we'll charge them. This might happen if the owner has done work that's damaged our pipes.

How to get it

Ask one of our Property Link brokers to apply for you – they'll charge for the certificate and add their agent fee.  You can find out how much a certificate will cost at prices for other services.
