Solutions for Council to Stop Polluting Sydney Harbour

Solutions for Council to Stop Polluting Sydney Harbour

Intern with Sustainable House, Alex Smith, describes solutions to stormwater pollution.

1.        Automatic irrigation spray onto surface of Council Garden bed, 9 September 2026

2.        Water runs down the sloping garden bed which has bare soil, no mulch

3.        Surface of garden bed soil is higher than garden bed and water overflows to footpath below

4.        Water and mobilized soil flow down footpath that slopes to road and gutter, eventually to pollute Sydney Harbour with brake linings, sediment, poison sprayed by Council on ‘weed’, nitrogen and phosphorus from Council fertilizers

30 years off grid in the city

30 years off grid in the city

In 1996, three decades ago this year, I disconnected my city house from town water, town sewer, town stormwater and installed solar panels.

Perhaps the first in a city. But being ‘first’ had nothing to do with it, except that made it harder to get approvals, get my sketches turned into drawings (designers, architects, engineers wanted nothing to do with it). I did it for two reasons; one, in a child-like way because everyone said, “You can’t do that”, so I appreciate the spur to action they gave me. And, because I was tired of my inner voice saying you’re polluting the ocean, harbour and air and knew that only by taking action could I free myself from that lack of integrity in myself.
