Kensington Holdings are developing a 400 ha (1000 ac) cotton irrigation scheme near Warra on the Darling Downs, Queensland. FSA Irrigation undertook hydrological simulation modelling to determine the reliability of the scheme given the available flood harvesting licences. A 1200 ML ring tank was then designed. FSA Irrigation gave advice on construction supervision and soil types. Registered Professional Engineer of Queensland (RPEQ) certification was provided.
