Find sanitary drainage plans
Use the WebMap system to find internal as-constructed sanitary drainage plans for domestic or commercial properties.
Finding a plan
The fastest way to search for a plan is using its street address - eg 77 Grenfell St, Adelaide. As you type, the inbuilt address finder suggests results that match your search. Clicking the appropriate search result or the magnifying glass will direct you to a map with a pin dropped at the appropriate address.
If you do not know the street address, you can also search by:
- location - eg Adelaide Showgrounds
- 10-digit valuation number (which is also the SA Water account number)
- latitude and longitude - if you have a smart phone with a latitude/longitude app, enter the appropriate values into the WebMap search, starting with ‘c:’, eg c:-35.55322,138.54667
- special sheet number, if an area needs greater detail, like in the Adelaide CBD - search in WebMap by entering ‘s:’, followed by the special sheet number, eg s:SP802
- old SA Water plan number (GIP number) - search in WebMap by entering ‘p:’, followed by the plan number, eg p:GIP-1037509/425974230
Viewing and downloading plans
Plan on file - orange shading
If the search results are shaded orange, click on the shaded property area (not the green dot) and then click ‘find drainage plans for this property’. A drainage plan link will appear - click ‘download - tif’ to open the plan. Depending on the web browser you use and your computer settings, the image will either appear on screen or download to your computer.
The plans identify the positions and dimensions of pipes, fittings and equipment that make up the sanitary drainage systems.
If the plan you download has a book reference or VIDE number on it, additional plans are available for the property. Search in WebMap by entering ‘b:’, followed by the book number - eg b:86/4587.
Search results also showing plans for a different address
For older records, it was common for multiple property plans to be drawn on the same page of a record book. When these drawings were scanned and added to the database, they may not have been correctly split, which is why the search results bring up a second, incorrect plan.
Please contact the OTR if you encounter this issue, so we can correct it.
No plan on file - grey shading
If the search results are shaded grey, there are no plans available for the property.
Drainage plans may not be available if:
- the property does not have access to SA Water’s main sewer line
- a property was constructed or modified between January 1977 and July 1981, as plumbing contractors weren't required to provide internal drainage layout plans to councils or regulating bodies during this time
- a plumbing contractor never submitted the drainage plan to the regulator.
Please note the OTR only holds internal as-constructed sanitary drainage plans, not water or storm water plans.
CD references on a property with no drainage plan record
A ‘CD’ symbol indicates the internal drainage system for a property has a common drain, which means it connects to a drain with an adjoining property.
This will be most commonly found in the Adelaide CBD and older suburbs, as it was common practice for a number of properties to use the same sewer main connection point and internal waste water drain in the early 1900s. These days, pipes must not cross allotment boundaries.
Finding pipes without plans
There are a number of ways to locate water pipes on a property, including using close circuit television vision (CCTV), metal detectors, acoustic pipe locators, radar, excavation and so on.
A number of plumbers specialise in locating drains. To find a licensed plumber in your area, check your local business directory (eg Yellow Pages), search online, or contact the Master Plumbers Association.
Displaying government inspection point locations
To display government inspection point (GIP) locations on the map:
- Click 'legend' on the top right-hand corner of the screen
- Check 'waste water' box
The SA Water sewer main lines and GIP locations will overlay on the search results map.
