Quarry Monitoring for Resource Consent. Real-time Data.
We are BPO. We deliver wastewater treatment solutions in real time and with pin point accuracy. Our data will keep your quarry compliant, now and in the future.
Quarry Monitoring
Don’t leave your wastewater treatment compliance to chance, BPO offers real-time monitoring solutions for harsh quarry environments. Stay compliant with precise data to accurately inform your environmental compliance.
New Zealand has a significant gap in reliable quarry water quality data. BPO leads the way with advanced water monitoring technology.
Quarries are navigating stricter resource consent conditions and environmental responsibilities. Modern resource consents often impose limits on temperature, pH, salinity, oxygen levels, discharge timing, and flow rates, as well as sediment discharge and turbidity. Effective quarry water treatment requires high-quality, consistent data for everyday compliance and long-term strategic planning. At BPO we make sure you’re compliant now, and in the future.
We offer real-time monitoring, portable solutions and pinpoint accuracy in quarry monitoring.
If you want accurate, real time monitoring you can trust, have a chat with us.
We are a 100% Kiwi-owned wastewater treatment business with decades of experience behind us. We value a human approach, the team you talk to, is the team on the ground. Pinpoint accuracy, everyday compliance and a future focused approach - our superpower? We can spot a problem before it is a problem.
Monitoring Services
Universal Portable Monitoring Platform
New Zealand’s exclusive portable wastewater monitoring solution. Flexible, accurate, real-time monitoring without relying on mains power so you can maintain resource consent compliance with minimal operational disruption.
Our seven weatherproof, lockable trailer-based monitoring platforms provide real-time data via a web interface. Configurable to your site’s specific needs, parameters include:
Flow
Turbidity/fine sediment
Temperature and salinity
Dissolved oxygen
pH and ORP
Ion-specific electrodes
UV spectrophotometry
Refrigerated auto-sampling for heavy metals, hydrocarbons, particle size distribution, and COD analysis
With a short mobilisation time, this platform is ideal for fault investigations, treatment optimisation studies, and compliance monitoring.
Permanent Monitoring Installations
We provide permanent monitoring stations for key quarry water parameters such as turbidity, pH, and dissolved oxygen. These stations can be mains - or solar-powered and communicate via area networks, cellular modems, radio, or satellite.
Open Channel Flow Measurement
For highly variable quarry water flows, we offer reliable flow measurement using Palmer Bowlus Flumes, Parshall Flumes, Venturi Flumes, Cipoletti Weirs, and V-notch Weirs.
Tracer Tests
Rhodamine and lithium tracer tests help assess quarry water capture effectiveness, identify leaks, and evaluate hydraulic retention and mixing behaviour.
Sludge Mapping
Using remote-controlled boats with sonar or manual methods, we survey treatment ponds to determine sediment and sludge buildup, ensuring optimal treatment system capacity.
Wet Sampling Programmes
BPO designs and implements automated or manual sampling programmes to assess quarry water quality, ensuring effective treatment and regulatory compliance.
Coagulation, Sedimentation, and Floatation Studies
We conduct laboratory and pilot-scale tests to determine the best processes and additives for solid separation in quarry water.
Automated pH Correction
Our premanufactured pH correction dosing stations automatically adjust quarry water pH levels, integrating monitoring, chemical dosing, and control functions in one skid unit.
Aeration Design and Optimisation
We assist in selecting and positioning aeration equipment to enhance treatment efficiency and reduce operating costs for quarry water with low oxygen levels or high organic loads.
Process Optimisation
Our experts identify opportunities to improve existing treatment processes, reducing operational costs and delaying expensive upgrades.
Operator Training
We offer training courses to help quarry staff understand and manage quarry water treatment and reuse technologies effectively.
Technical Service Agreements (TSA)
TSAs provide ongoing technical support, including remote monitoring, data analysis, and on-site visits, helping operators detect and resolve issues before they escalate.
