WAI EYE – KANOHI HŌMIROMIRO
Water Infrastructure Intelligence
See your network clearly.

BTW have a team of multidisciplinary specialists focused on solving water issues.
Wai-eye combines UAV, remote sensing, IoT and environmental science to prioritise renewals, calibrate models, monitor water quality and protect communities, aligned with Te Mana o Te Wai. Delivered nationwide.
Why choose this service:
- Decision ready dashboards instead of lengthy reports
- Faster leak and defect detection to save cost and reduce water loss
- Water quality surveys and physio-chemical analysis to detect risks early and support compliance
- Practical calibration and early warning insights to build network resilience
Wai-eye addresses common three waters challenges including leak detection, stormwater calibration, wetland monitoring and inflow and infiltration (I&I) in wastewater. Our Three Waters services provide advice and design to help you equip your site with infrastructure to manage wastewater (sewerage), stormwater drainage and drinking water.
Water quality surveys provide physio-chemical analysis of key parameters such as clarity, oxygen and nutrients. This supports compliance, delivers early warning of contamination, and helps councils and asset managers prioritise investment where it matters most. Deployment is rapid and available nationwide. Results are presented in clear dashboards that support decision making and allow for faster, targeted responses.
HOW WE HELP:
- Stormwater network surveys and sensors
- Leak detection using thermal, multispectral, flow and pressure data
- Water quality surveys and physio-chemical monitoring
- Wetland identification, monitoring and wastewater I&I analytics
AWARD WINNING INNOVATION:
Recently BTW Company won the Innovation Forum Award at the Water New Zealand Conference & Expo in Kirikiriroa – Hamilton for our Aerial Sludge Sensing for Wastewater Pond Management solution.
Part of BTW’s Wai Eye – Water Infrastructure Intelligence capability, the system uses an airborne sensor to assess wastewater pond sludge. No boat crew. An airborne sensor.
- Senses and samples consistently
- No one touches the sludge (removes hazards and risks)
- Repeatable and verifiable
The system is operated by independent qualified surveyors and CAA-certified UAV pilots, providing smart tools for compliance while improving safety, data quality and decision-making.
