Port Water Control – AI-based Spill Detection

Spanish startup Port Water Control builds an automatic spill detection system for harbor waters that applies AI and image recognition to monitor surface water conditions in ports. The startup installs Neptunes, intelligent sampling units that continuously capture images of the water surface. They analyze them to identify spills or signs of pollution in real time.

Then, the system generates early alerts that support rapid response and data-driven environmental management before contamination spreads. Also, aggregated monitoring data provides ports with measurable insight into recurring spill patterns and operational impacts on water quality.

Otter Intelligence – Wastewater Optimization

Dutch startup Otter Intelligence develops a data- and AI-driven optimization platform for wastewater treatment and water quality monitoring. It continuously collects and analyzes plant and water quality data to model system behavior, detect deviations, and optimize treatment processes in real time.

As a result, the platform enables smart chemical dosing, advanced data visualization, and direct alerts with predictive maintenance. It also offers agenda optimization, remote monitoring, instant reporting, and AI chatbot-based operational advice within a single system.

Manta Biosystems – Microbial Detection System

US-based startup Manta Biosystems offers MantaVision, an automated molecular monitoring platform that detects viable microorganisms and viruses in water and processes samples.

The system operates as a fully automated cartridge-based polymerase chain reaction (PCR) workflow. In this, samples are filtered and lysed, nucleic acids are purified and combined with reagents, and semi-quantitative PCR analysis produces a digital readout that integrates with laboratory information management systems.

With this, the platform supports multiplex detection of up to 24 targets with high sensitivity, minimal hands-on time, and reduced contamination risk through single-use consumables.

WaterSense – Autonomous Floating Laboratories

Italian startup WaterSense builds an autonomous floating laboratory network that delivers real-time inland water quality data intelligence for rivers and lakes. The startup deploys energy-independent modular stations that continuously draw water from multiple depths. They perform laboratory-grade measurements under controlled internal conditions, and transmit data to a cloud platform where AI analyzes, forecasts, and integrates satellite observations.

Thus, the startup replaces manual sampling with live monitoring, smart alerts, predictive early warnings, and standardized data access through maps, reports, APIs, and forecasting models.

Additionally, proprietary anti-biofouling technology ensures stable long-term accuracy. Also, hybrid solar and optional hydro power enable maintenance-free operation without external infrastructure.

WaterScope – Bacterial Testing

Ethiopian startup WaterScope builds a field-deployable drinking water testing system. It detects bacterial contamination by refining the ISO 9308-1 membrane filtration process into a compact, digital workflow.

The process begins by assembling a membrane and an absorbent pad inside a slider. This slider is secured within a metal cartridge and connected to a motorized vacuum pump that draws a water sample through the membrane.

As water passes through the membrane, bacteria are trapped from sample volumes of up to 100 mL. This step concentrates microorganisms for accurate downstream analysis.

Next, liquid nutrient media is added to the absorbent pad. The cartridge is then placed into an integrated incubator where bacterial colonies grow under controlled conditions.

A built-in microscope captures high-resolution images of early bacterial growth. A machine learning algorithm automatically identifies and counts bacterial colonies.

The results are uploaded through an embedded IoT module to a central dashboard. This dashboard enables real-time mapping, trend analysis, and historical tracking of water quality data.
