What to know about Concerns over camper wastewater chemicals in regional wastewater systems

Researchers from Flinders University have studied the impact of caravan toilet chemicals, specifically bronopol, on regional wastewater treatment systems. The study suggests that these concentrated disinfectants may disrupt the microbial communities necessary for effective wastewater treatment, particularly in smaller regional plants.

What happened

Concerns over camper wastewater chemicals in regional wastewater systems Lisa Lock Scientific Editor Andrew Zinin Lead Editor The surge in caravan and camper usage within Australia could place extra pressure on regional wastewater treatment systems because of…

Why it matters

When people using caravans empty their toilet waste at roadside dumpsites, caravan parks and regional dump stations, the wastewater—which contains concentrated detergent, deodorizer and sanitizer chemicals—is transported to local wastewater treatment plants.

Common ground

Flinders University researchers focused on whether caravan toilet chemicals such as bronopol, a powerful disinfectant chemical, may disrupt wastewater treatment microbes.
