Building Plan Approval / Tap In

Please fill in & submit the the Building Plan Approval Application below and one of our team will be in touch shortly

If you’re building, excavating, or landscaping over or next to Sydney Water assets, we must approve your plans before you start. To start the process you will need to lodge your plans with Sydney Water though Tap In.

If you make the application through Tap In Sydney Water will ask a few short questions. Sydney Water will use this information to tell you if your works might affect or limit access to our assets.

There are two outcomes from that assessment:

  • Sydney Water will approve your plans without further assessment.
  • Your plans will need further assessment and you’ll need to submit your application or email that you receive from Sydney Water with you REF Number to PR & CM Drafting for a quote on works required for approval. Time frames will depend on your requirements and this can be advised at the time of quote


PR & CM Drafting carry out this application on your behalf. To do this we require a copy of your approved plans.

At the end of the process, we’ll approve your building plans. You’ll then be able to show your approved plans to your consent authority for your construction certificate.

No Building work shall commence until the approval has been received


We require a Full Site plan that is to scale. Once we receive this, sewer is then plotted.
If your structure falls with the ‘Zone of Influence’ then we advise you of any extra cost that you may incur.
If your structure is outside the ‘zone’ then turn around time is approximately 2-3 days.
