What Is Sydney Water Tap-in?
Tap-in is Sydney Water’s online system that checks:
Sewer main locations
Easements
Connection points
Depth and alignment of pipes
Whether your proposed building encroaches on Sydney Water assets
A Tap-in Certificate must be issued before a Construction Certificate (CC) is granted.
Our Sydney Water Tap-in Service Includes:
Sewer Service Diagram (SSD) Review
We identify sewer mains, junctions, easements and potential conflicts before submitting.
Tap-in Portal Submission
We upload all required plans and information, including:
Site plan
Floor plans
Elevations
Sections
Stormwater concept plan
Building Over/Adjacent to Sewer (BOAS) Checks
If the building impacts Sydney Water assets, we manage:
BOAS assessments
Engineer design revisions
Additional approval requirements

Working With Sydney Water Providers
We coordinate requests with:
Water Servicing Coordinators (WSCs)
Sydney Water authorised inspectors
Engineers (if sewer encroachment occurs)
Certificate Delivery
Once approved, we provide the Tap-in Certificate directly to your builder or certifier.
Why Tap-in Matters
Without a valid Tap-in Certificate:
your CC cannot be approved
construction cannot legally begin
delays may extend several weeks
redesigns may be required if sewer conflicts exist
Our service ensures your application is accurate and compliant from the start.
