LOCALLY OWNED, FAMILY OPERATED & COMMUNITY FOCUSED
At the heart of Enviroking’s success is a proud family legacy. Established over 40 years ago and carried forward by the next generation, the business continues to operate with the same values of honesty, integrity, and care that it was founded on. In 1998, the team moved to their current premises, where they built a state-of-the-art liquid waste treatment facility that opened in 2000.
This investment in local infrastructure not only improved efficiency but also allowed Enviroking to better serve a wider region — including Central Coast Council, Cessnock City Council, Dungog Shire Council, Lake Macquarie City Council, Maitland City Council, Muswellbrook Shire Council, Newcastle City Council, Port Stephens Council, Singleton Council, and Upper Hunter Shire Council. As the business grew, so did its fleet — expanding from just two trucks to ten modern vehicles capable of handling a wide range of waste removal tasks efficiently and safely.
