Southern Highlands Irrigation was established in 2000 with the store opening in Unit 4 Linkwood Court, Cavendish Street, Mittagong. The business at that time focused primarily on the irrigation division of the business.

Over the next few years the pool and spa retail and service division of the business continued to grow to a point where it is now over half of the business. ln 2008 the business moved to Unit 4 in the newly built Cavendish Centre on the corner of Cavendish and Davy Streets. The business also had a name change to Southern Highlands Water Plus to reflect the broader base of both irrigation and pool divisions. Both names are still used and are registered trading names.
