HULO Real-time Water Intelligence

HULO is a water intelligence company based in Leeuwarden, the Netherlands, that started with leak detection for drinking water networks. Its about page mentions a seed round in 2025, ISO 27001 certification and a presence in Asia and the Middle East.

The software reads the pressure and flow sensors a utility already owns and compares measured against expected values per node every minute using the hydraulic model. It does not need new hardware or district metered areas, is read-only toward SCADA and historian, and can ingest acoustic data to confirm a location. Named customers include Portsmouth Water, Aegea, Nama Water Services and Vitens.

• Real-time detection: compares measured and expected pressure and flow per node every minute.
• Leak localisation: narrows the search area, reported at 250 x 250 m in one deployment.
• Hydraulic model integration: converts GIS to a hydraulic model and uses existing models.
• Read-only SCADA link: connects to SCADA and historian without writing back.
• Acoustic confirmation: ingests acoustic data to confirm a location.
• Tiers: Essential, Professional and Enterprise with simulation and sensor placement optimisation.

Continuous leak detection on trunk and distribution networks of large Vietnamese water companies that already have SCADA. Narrowing the search area before field crews with acoustic equipment are sent. Sensor placement optimisation when expanding monitoring to new zones.

No new sensors or district metered areas are required. In controlled tests at Aegea / Aguas do Rio, leaks detected rose from 1 in 10 to 9 in 10 and the search area fell from 500 km to 2 km. The page states 95% alarm accuracy and six weeks from contract to first confirmed detection. Failed tests are published alongside successes.

Utilities hold more sensor data than they use and look for software that works on existing instrumentation. Vietnamese and Southeast Asian utilities that already log pressure and flow at DMA inlets can apply model-based detection without new hardware. Security certification such as ISO 27001 matters for public water operators.

Based at Zuiderplein 4-6, Leeuwarden (Netherlands). Seed round in 2025, co-financed by the EU, SNN and the Dutch Ministry of Economic Affairs. ISO/IEC 27001:2022 and NIS2 Quality Mark SC30. Founding year not stated.
