Watersight

Watersight is a joint venture between Newsight Imaging (sensor-semiconductor and spectral-imaging specialist) and Mekorot (Israel’s national water company). The firm’s flagship product, AquaRing, pairs a low-cost spectrometer-on-chip with embedded learning models and cloud analytics to provide continuous, always-on water condition monitoring from source to tap. The device captures narrowband spectral measurements and then runs lightweight edge inference and cloud-based model training to surface anomalies, classify likely causes, and generate actionable alerts for operators.

The core technical approach centers on a compact CMOS spectral sensor, a constrained sampling and pre-conditioning module, and a model-per-site machine learning architecture. Newsight supplies the spectral CMOS chip and optical stack, which reduces cost and enables deployment places where traditional laboratory or bench-top spectroscopy is impractical. Watersight augments the hardware with site-adapted ML models that learn the local baseline and detect deviations (anomalies) rather than relying exclusively on fixed-rule thresholds. That makes the system resilient to seasonal and source variability while highlighting events that merit human inspection.

Customer and market validation has been anchored by Mekorot: the AquaRing pilot launched in late 2022 and, following positive results, Watersight expanded installations to additional remote Mekorot sites in 2023. Mekorot’s involvement is material for both commercial and technical validation—operational feedback from a national water utility accelerates sensor calibration, regulatory acceptability, and deployment practices. Watersight has also positioned AquaRing for the beverage, industrial process, and water-purification markets where inline, low-latency quality checks add clear value.

Traction to date is modest but credible. Watersight won the Extreme Tech Challenge (XTC) Sustainable Smart Cities award at CES 2023, demonstrating early industry recognition. Public reporting and company statements indicate pilot success and invitations from some US and European water and beverage firms to trial the system. The company emphasizes scalability and low unit cost as its primary route to market, aiming to enable denser telemetry across distribution networks than is typical with existing lab sampling programs.

From a competitive standpoint, Watersight sits between high-end, lab-grade spectrometers and commodity point sensors. Competitors include incumbent industrial instrument vendors (e.g., Xylem/Hach/Endress+Hauser) and specialist spectral or optical sensor providers (including Newsight’s partners and other spectrometer-on-chip entrants). Watersight’s differentiator is the integrated package: a sensor stack designed for field durability, per-site ML adaptation, and a utility-level operations workflow, plus Mekorot as an early anchor customer. The JV structure provides privileged access to validation sites and operational data that can materially shorten the typical adoption cycle for utilities.

Strategic and dual-use relevance is real. Water distribution and purification are critical national infrastructure: continuous, low-cost, wide-area sensing helps detect contamination events (chemical adulteration, algal blooms, industrial discharges) earlier than periodic sampling and lab analysis. For resilience planning, denser real-time telemetry can improve incident isolation and reduce downstream public-health exposure. While AquaRing is not a chemical weapons detector, its spectral+ML approach can flag anomalies that warrant targeted CBRN laboratory follow-up; this makes the platform adjacently valuable to civil-defense and infrastructure-protection organizations. However, the company does not publicly claim CBRN certification or military contracts, and such use would require careful regulatory and technical validation.

Open diligence questions include: how robust are the spectral models across turbidity, temperature, and biofouling conditions; how often does the model require site re-training; what is the false positive/negative profile in large-scale deployments; and what are the device maintenance and calibration workflows for multi-year field service? Supply-chain risk for the spectral CMOS chip is mitigated by Newsight’s vertical capabilities, but scaling to thousands of nodes will stress production, firmware management, and field-service logistics. Overall, Watersight’s positioning—low-cost spectral sensing plus ML, validated by Mekorot—makes it a strategically interesting entrant in water-security-adjacent sensing with tangible dual-use and resilience applications.
