Sydney Man Lives Sustainably Off-Grid for 30 Years

A retired lawyer in Sydney is saving approximately $3,500 annually by living off-grid. Michael Mobbs, 75, disconnected his Chippendale terrace from city water, electricity, and sewage in 1996. He installed solar panels for power and a rainwater collection system for drinking water.

His home features an advanced wastewater recycling system that treats over a million litres of dirty water annually. This sterilized water is then reused for flushing toilets, watering the garden, and washing clothes. Mr. Mobbs, who previously worked as a lawyer and consultant for the Environment Protection Authority, was inspired by a desire to address Sydney's water management issues.

Mobbs's self-sufficient lifestyle includes a three-bedroom terrace with typical household amenities like a fridge, washing machine, and shower, all powered by his off-grid system. Despite initial questions from his family about the feasibility and marketability of such a home, he has maintained this way of life for nearly three decades.

While proud of his sustainable choices, Mr. Mobbs has had ongoing disputes with Sydney Water over an unpaid stormwater drainage charge. He advocates for broader adoption of off-grid solutions, suggesting that even small changes like installing a rain tank can significantly reduce household costs and environmental impact.
