What Sydney Water is responsible for

We're responsible for ensuring connections to our pipes meet our standards. We might inspect the connection if we have specific connection requirements, eg holding tanks, pumps or wastewater treatment equipment. These will be included in our additional services agreement with you.

If we need to do an inspection, we'll organise this after:

  • you apply to connect
  • we've approved your connection.
