01What changes in Darwin
The NT EPA says material placed in stormwater drains flows untreated to rivers or creeks and advises minimising water and detergent and preventing wash water from running down stormwater drains. City of Darwin says its stormwater system is managed to minimise pollutants entering the network and protects the harbour with gross-pollutant traps. Darwin campaigns should translate that into operational questions rather than a vague environmental badge: identify the down-slope drain, surface contamination, proposed products and containment plan.
Darwin, Palmerston and Casuarina can have different scheduling from Howard Springs or Humpty Doo, where travel, tank water, septic systems or unsealed access may matter. Wet-season forecasts and intense rain can require rescheduling, while older or unidentified fibre-cement surfaces must never be offered high-pressure cleaning without asbestos assessment.
