Safe Dechlorination
Chlorine: Safe in your glass, dangerous in our rivers
Chlorine keeps our drinking water safe, killing harmful germs like bacteria and viruses.
But when chlorinated water is released during flushing, commissioning or maintenance, it can harm rivers and creeks. The national water-quality guidelines set a very low limit for rivers: no more than 0.003 mg/L of free chlorine, so low that most field meters can’t detect it.
Even tiny amounts of chlorine can:
-
Damage aquatic life by oxidising cells and gills, and
-
React with organic matter to form toxic by-products.
Drinking water commonly contains 0.5–4 mg/L (safe for people), yet as little as 0.01 mg/L can harm aquatic organisms. Whenever water is discharged to the environment, it must be carefully managed and dechlorinated.
Dechlorinate as you discharge.
Regulatory expectations are rising.
Australian utilities and industries are under increasing pressure from environmental regulators to prevent chlorinated water from entering rivers and other sensitive waterways.
Although there are currently no national dechlorination guidelines, the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC/ARMCANZ) set strict limits for chlorine to protect aquatic life, and state EPAs often use these values when assessing environmental risk.
In practice, regulators expect operators to follow best-practice standards particularly when managing high-chlorine discharges from flushing, commissioning, or maintenance activities.
Recent history shows the consequences: several EPA fines and prosecutions have followed spills and failures of dechlorination systems, underscoring the need to manage chlorinated water carefully and in line with both environmental guidelines and regulatory expectations.
A Simple, Safe, Sustainable Method
Dechlore provides a reliable, field-proven method to safely, quickly, and cost-effectively remove chlorine compounds from water.
Dechlore works by naturally neutralising chlorine and chloramine on contact. Unlike other agents, it is biodegradable, non-toxic, and harmless to aquatic life, breaking down into compounds that are already common in the environment.
Because it is safe for people, operators can handle Dechlore without special protective equipment, making it a practical and low-risk option in the field. The tablets dissolve rapidly, ensuring fast and complete dechlorination even during high-volume flushing or emergency discharges.
For utilities, this means peace of mind:
-
Environmental compliance – helps meet EPA expectations and ANZECC/ARMCANZ guideline values for chlorine in waterways.
-
Worker and community safety – no hazardous chemicals to transport, store, or apply.
-
Sustainability – a natural solution that aligns with corporate environmental and social responsibility goals.
-
Cost-effectiveness – simple to use, reducing the risk of fines or costly remediation from accidental chlorine discharges.
With its organic, natural, and non-toxic formulation, Dechlore is your safe, sustainable, and regulator-ready solution for managing chlorinated water.
