Conveyancing (Section 66) certificates

A conveyancing certificate, also known as a Section 66 certificate, identifies outstanding property charges. Selling agents and conveyancers use the information on the certificate to allocate outstanding charges between the current and new owner.

Ask a Property Link broker to apply for you – they'll charge for the certificate and add their agent fee.

Service location prints

A service location print shows our pipes and structures on a property and 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.

Purchase direct at Sydney Water Tap in. Or ask a Property Link broker to apply for you – they'll charge for the print and add their agent fee.

Sewer service diagrams

A sewer service diagram (also known as a property sewerage diagram or sewer diagram) shows the private wastewater pipes on a property. Plumbers use these diagrams so they can clear blockages or change pipes. Selling agents and conveyancers use this diagram to check:

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

Buildings and pipes are shown, but not pools. NSW Fair Trading, and now Building Commission NSW, have inspected private plumbing work since 2012. Before 2012, Sydney Water inspected private plumbing.

Most diagrams are available almost immediately. However, if we need to investigate something on a diagram it may take up to 7 days.

How to read your diagram

  • See Help with your sewer service diagram to find out what a symbol means.
  • If there's plumbing that's not on the diagram, it may not have been inspected. To check, call us on 13 20 92 8am–5:30pm Monday to Friday (except public holidays).
  • Is your diagram old? If it shows the plumbing the way it is, it's fine. If not, call us on 13 20 92 8am–5:30pm Monday to Friday (except public holidays) and we'll look into it for you.

Building over or adjacent to asset letter

A building over or adjacent to asset advice letter (also known as 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.

Ask a Property Link broker to apply for you – they'll charge for the letter and add their agent fee.

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 a 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.
  • If you're selling a property, ask your solicitor or conveyancer how water use will be determined at settlement. Use charges and water usage calculators to help work out charges.

Ask a Property Link broker to apply for you – they'll charge for the reading and add their agent fee.

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 is not 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 will charge them. This might happen if the owner has done work that's damaged our pipes.

Ask a Property Link broker to apply for you – they'll charge for the drawing and add their agent fee.

Asset construction drawings

We complete asset construction drawings (longsections or benchmark plans) after we've laid new pipes. These drawings, known as 'work as constructed plans', show where the pipes are in relation to street and property boundaries. They're generally used for construction or excavation purposes and when a plumber wants to connect to our pipes.

Supply system diagrams

Supply system diagrams are large-scale plans from our computerised mapping system. They show how the water supply system serves a particular property within a building development. The information shows the location of our water pipes over a large area, and highlights:

  • the water supply zone
  • larger water mains within the supply system
  • the nominated property.
