A Tribute to an Aquatic Industry Pioneer

We are deeply saddened by the sudden passing of Peter Hobson, aged 76, a respected leader of Chadson Engineering and a true icon of the Australian and international aquatic and engineering industry. A visionary from a young age, Peter played a pivotal role in shaping the future of domestic backyard pools in Western Australia. Through his foresight and entrepreneurial spirit, he established a residential division within Chadson Engineering that, at its peak, captured up to 80 per cent of the Western Australian market. This achievement helped define the modern residential pool landscape in WA and set new benchmarks for the industry.

Peter was also instrumental in uniting the industry, helping to instigate the WA Pool Builders Association (CASPA). He firmly believed in collaboration – working for a common cause rather than against one another – and his leadership helped strengthen relationships and professionalism across the sector.

His impact on the commercial aquatic industry was nothing short of world-leading. In the mid-1970s, Peter designed and created the world’s first horizontal high-speed fibreglass sand filters, later known as the Chadson MHS filters. These pioneering products achieved global adoption and remain widely used today. Currently, it is estimated that 50 to 60 per cent of commercial pool filters across Australia, and approximately 80 per cent in Western Australia, are Chadson MHS filters, with a strong presence throughout the Asia-Pacific region. Peter later went on to develop the CPC model filters, further cementing Chadson Engineering’s reputation as an industry leader.

Peter possessed an intimate working knowledge across many facets of the aquatic industry, blending deep technical expertise with sharp commercial insight. Despite his extraordinary achievements, he remained a private, humble and quietly influential figure, preferring to work behind the scenes and let outcomes – and people – speak for themselves.

Above all, Peter was a kind, warm-natured, and highly respected man who cared deeply for his family, colleagues and the industry he helped build. He was much loved by all who knew him, and his legacy – both personal and professional – will endure for generations.

Peter Hobson leaves behind an extraordinary contribution founded on innovation, collaboration and integrity. He will be greatly missed.

Our heartfelt condolences are extended to Peter’s family, friends and colleagues during this difficult time.
