As of October 2026, the guide has three water treatment businesses across three suburbs, most of them in Rockville, South Toowoomba and Toowoomba City. Of those, two have a website we check every day. The other one come from public records, with a phone number where one is published.
As of October 2026 the Toowoomba Business Guide lists 3 water treatment businesses across 3 suburbs, from the city centre to Highfields, Oakey and the Downs towns.
Rockville, South Toowoomba and Toowoomba City have the most listed water treatment businesses. Every suburb with at least one is on this page.
Every day the guide checks each business it lists. A business comes off the guide only when there is clear sign it has closed, seen on two checks at least 7 days apart. A slow or briefly down website never removes it. Of the 3, 2 have a website that is checked daily.
