Who needs to complete the form?

The business that will create the trade waste discharge will need to fill in the form. If you are not the property owner, you will need to work with your property owner to properly allocate the responsibility for plumbing and drainage works and other property management matters.

Remember to apply for an authorisation before you engage a licensed plumber to install or modify any required plumbing or fixtures.

Application process

  1. Check which form you need to complete. 
  2. Read through the guidelines for your industry
  3. Complete the correct application form: non-complex business or complex business
  4. Pay the correct fee
  5. Wait about 10 business days for us to process your application.

If your application meets all requirements, we will issue your trade waste discharge authorisation. If we need more information however, we may need to arrange a site inspection with you.

  • Water Quality
  • Some Adelaide Hills customers may notice changes in the taste and/or smell of their tap water, as we work hard to reduce the impact of an algal bloom in the Summit Reservoir.
    The algal bloom is causing a naturally occurring compound called geosmin, which can affect water taste and odour, but is harmless to health. The water remains safe to drink.
    We expect customers in the following areas may notice this change: Mount Barker, Balhannah, Oakbank, Verdun, Hahndorf, Heathfield, Stirling, Crafers, Lenswood, Lobethal, Woodside, Brukunga, Mount Torrens, Birdwood, Gumeracha, Kersbrook, Cudlee Creek, Wistow, Nairne, Littlehampton, Strathalbyn, Clayton, Milang, Langhorne Creek and Bridgewater.
    We have made changes to our treatment processes at the Summit Water Treatment Plant to reduce the level of geosmin in the water.    
    Our testing shows no algae has been detected in the network and it has been completely removed as part of our normal treatment process.
    If our customers have any questions or concerns, please contact us on 1300 SA WATER.
