AS Roof 3-Yearly Water Quality Monitoring (No Chimney or Open Fire)

For drinking water supplies using the Acceptable Solution for Roof Water Supplies (AS-RW), this suite provides 3-yearly testing of rainwater quality to assess key chemical parameters, ensuring the long-term safety of the supply.

Why This Suite Is Important

Collected rainwater can accumulate metals from roofing materials and fittings, potentially impacting water quality. This 3-yearly chemical analysis ensures that key metals such as lead, copper, cadmium, and zinc remain within safe limits, preventing long-term health risks.

The Maximum Acceptable Values (MAVs) and treatment limits for these determinands are:

  • Cadmium: 0.004 mg/L
  • Copper: 2 mg/L
  • Lead: 0.01 mg/L
  • Zinc: No MAV, but high levels may cause taste and plumbing issues
  • 📌 If you have a Safe Supply Online Drinking Water Safety Plan, your test results can be automatically shared with the online tool, made available to members of your water supply, and scheduled for submission to the regulator as required.
  • 📌 Results must be retained for at least 5 years and made available to all members of the water supply.
  • 💬 Need Help?
  • Once you receive your results, we can introduce you to a water quality expert with knowledge of drinking water and treatment options to assist in understanding the results and developing a drinking water supply strategy.
