Water Quality & Discharge Monitoring
Fulfill Your GED. Automate Compliance. Protect Local Waterways.
Overview
Replace guesswork with legally defensible data
Dewatering and sediment basin management are under intense scrutiny in Victoria. Under the General Environmental Duty (GED), discharging non-compliant runoff into local creeks or stormwater networks can lead to instant EPA audits, stop-work orders, and devastating financial penalties.
At OmniSense, we deploy real-time telemetry and advanced multi-parameter arrays that continuously track your discharge, automate shut-off safety systems, and legally insulate your project from liability.
Why Choose OmniSense?
- The "Upstream" Liability Shield: we mathematically isolate your project's true footprint. By establishing baseline, upstream water profiles, we legally prove if a local drainage network was already contaminated before your site water ever entered it.
- Fail-Safe Automated Mitigation: we integrate smart 4G telemetry with automated site plumbing, physical solenoid valves, and pump-stops to kill non-compliant discharges before a single drop hits the stormwater network.
- Industry-Standard Fleet Precision: ruggedised, high-accuracy instruments backed by daily, logged multi-point calibrations and NATA laboratory validation checks.
Standard Victorian Discharge Thresholds & Parameters
What we monitor
Our systems monitor, record, and upload critical water health metrics at continuous 15-minute intervals to a secure cloud dashboard.
| Parameter | Metric | Typical Victorian Discharge Limit | Proactive Operational Action |
|---|---|---|---|
| pH | pH Units | 6.5 – 8.5 | Automated chemical dosing or recirculation if readings drift outside limits. |
| Turbidity | NTU | < 30 NTU (or Background +10%) | Immediate trigger for sediment basin treatment (e.g. flocculation via gypsum). |
| Electrical Conductivity | µS/cm | Must match receiving water | Monitors changes in salinity or chemical runoff against natural ambient baselines. |
| Dissolved Oxygen | % Saturation | > 80% | Ensures discharged water maintains aquatic ecosystem health. |
| Total Suspended Solids | mg/L | Site-Correlated Limit | Handled via our proprietary, site-specific scientific translation modelling. |
The OmniSense Advantage — Scientific NTU-to-TSS Correlation: permits frequently mandate compliance limits in Total Suspended Solids (TSS in mg/L), but field sensors can only instantly measure Turbidity (NTU). At the launch of your project, our engineers pull physical grab samples to test them simultaneously for both NTU and TSS in a NATA laboratory, mapping the data to engineer a Site-Specific Correlation Graph — scientifically proving your exact mg/L TSS output in real-time on your live dashboard.
The Fail-Safe Field Procedure
From site characterisation to auto shut-off
- 01
Pre-Discharge Boundary Isolation
Rigorous testing on the upstream (background) water quality of the receiving creek or drain establishes the "natural" baseline state of the local waterway, ensuring your project is never held accountable for pre-existing regional contamination.
- 02
High-Flow Telemetry Placement
Probes are strategically suspended in high-flow zones of the sediment basin or dewatering discharge point. Inlets are positioned to avoid bottom-silt interference and surface-scum anomalies, capturing a completely accurate sample of the water column.
- 03
Automated Solenoid Interlocks
If a 15-minute rolling average for pH or Turbidity breaches your permit limits, our 4G data loggers instantly engage our Fail-Safe Protocol — transmitting an emergency signal to a solenoid valve or pump-stop, shutting down operations automatically and recirculating water back into the sediment basin for treatment.
Legal-Grade Documentation & NATA Audits
Certified accuracy, continuously verified
- ✓ Comprehensive Discharge Logs: automated tracking of total discharge volumes (kL), system start/end times, and average water metrics.
- ✓ NATA Validation: physical monthly grab samples are independently tested at a NATA-accredited laboratory to continuously verify and certify the pinpoint accuracy of our digital field sensors.
Secure your project's environmental defence
Do not risk an expensive EPA fine or an unexpected stop-work notice due to water runoff.
