The Real-Time Water Quality Monitor Solution

Helping New Zealand achieve clean, swimmable oceans, rivers and streams by providing a network of real-time water quality information. We’re committed to enhancing water for the generations to come.

“Kaua e kōrero mo te awa, kōrero ki te awa.”

"Don’t talk about the river, talk to the river.”

3,400K

Only 3,400kms of 425,000kms of New Zealand’s waterways are monitored

50%

We aim to monitor 50% of waterways, with 11,730 data points recored and counting

6

We have monitored 6 rivers so far, empowering 3 communities to enhance water quality

Smart Water Quality Data Interpretation

Our water quality monitor offers a wireframe of information about the quality of our oceans, rivers and streams. We provide insights into the ecological health, swimmability, environmental thresholds and mahinga kai values of our waterways.

Through powerful software, we interpret and communicate water quality information in a meaningful way, connecting the user with the waterway.

Empowering government organisations, businesses, local Iwi, and primary industries like forestry and farming communities to understand our integral connection with our water. We are enabling everyone to participate in stewardship and kaitiakitanga (guardianship) of our water.

Smart Water Quality Data Interpretation with AI Software

Our intelligent software paired with real-time information helps New Zealanders understand the health of the waters and assists in seeing a measurable change in our water quality management.

The Next-Generation Solution

Our next-generation water monitoring solution includes the hardware (Waka and Signal Mate) with the Software, IoT Connectivity and Servicing (subscription) to deliver a plug and play, cradle to grave system. Our solution remotely samples water quality every 15 minutes, sending valuable data back via cellular IoT or SWARM IoT satellite communications, using Artificial Intelligence and providing essential information and alerts in real-time. The RiverWatch Waka is a complete freshwater and saltwater monitoring solution with five sensors included and room to customise the solution to your needs.

Using the included sensor array you will have up-to-date information on:

Nitrate

The Waka includes room to upgrade by adding a discrete nitrate sensor at an additional cost. While nitrate can’t be tasted, seen or smelt, excess levels can be harmful. The sensor collects nitrate data in real-time. Coming to RiverWatch soon!

pH

pH level reflects water health, ensuring water is safe to use and drink. pH tests can help prevent disease risk by monitoring if levels fluctuate. Changes in pH can indicate contamination events and can seriously affect the abundance of aquatic life.

Learn More

Turbidity

Turbidity measures solids in water using the amount of light that can pass through. Turbidity readings can indicate land-based pollution and degradation. Soil lost to water causes high turbidity and significantly impacts downstream ecosystems.

Learn More

Temperature

Monitoring water temperature indicates the metabolic rate of aquatic life and their sensitivity to pollution, parasites and disease. The sensor can help determine changes in the thermocline that affect aquatic organisms.

Learn More

Conductivity

Conductivity measures the water’s ability to conduct electricity and indicates what is dissolved in water. High ion concentrations cause increased conductivity, with ions coming from contaminants like nitrates and phosphates.

Learn More

Dissolved Oxygen

Dissolved oxygen indicates an aquatic resource’s ability to support aquatic life, which also shows water health. This affects how ecosystems function and if they have the ability to support life.
