Dial Before You Dig enquiries

What the process looks like

• Visit 1100.com.au 24/7 to register or sign in.
• Lodge a free enquiry online to notify registered Dial Before You Dig members who own underground assets near your proposed excavation. They’ll be listed in your Caller Confirmation.
• If Sydney Water is on the list, you don’t need to contact us. We’ll respond to you directly and send plans of our assets by email or fax within a few hours. You can also choose to have the plans posted to you.

Make sure you define your dig site accurately when you lodge your enquiry. The plans you receive will only cover the area highlighted in the ‘Locality Indication Only’ window on your Caller Confirmation. They won’t reflect street address details or any other information in your enquiry.

What you’ll receive

We’ll send these documents by email:

• coloured PDF plans formatted to A4, A3 or A0 depending on the size of the site you identified in your enquiry (we can also fax or post these plans)
• Guide to reading Sydney Water DBYD Plans (609KB)
• Important information about Dial Before You Dig (286KB) terms and conditions.
