Wandong Caravan Park is located 70km north of Melbourne. There are 70 powered and 20 unpowered sites available for caravans, campers and motorhomes. DWW installed a treatment plant at Wandong Caravan park 40 years prior to the necessary upgrade. Due to a lack of maintenance on the initial plant, EPA required Wandong Caravan Park to upgrade their waste water system and obtain a Works Approval, as they had failed their licencing agreement with the EPA. DWW obtained approval to use treated effluent onsite and brought Wandong inline with current environmental policies and upgraded the system.
