Instrumented water, sovereign data.
A platform of communicating sensors with embedded intelligence. One hardware architecture; software capabilities (quality, hydraulics, metering) activated on demand, sensor by sensor.
The reality
A water network loses, on average, one litre in five. And stays, for the most part, blind.
Leaks surface too late, quality is checked by rounds, data is rented through a captive protocol. Drop! makes the network legible (to the metre, at the scale of a day) and returns the data to those who own it.
The reality, in figures
Water is poorly measured.
Networks lose close to one litre in five, regulation is tightening, and quality is still checked by rounds. Drop! instruments what used to stay invisible.

Our solutions
Measure. Analyse. Filter.
A complete chain, from sensor to tap: measure the water, analyse the data, filter at the point of use.

DiscoverWater matrices
One platform, every water.
The same sensor applies to every matrix: drinking water, surface water, wastewater, shellfish waters, pools. The regulatory context changes, never the technology.
“Water is our most precious resource, and one of the least instrumented.”
The Drop! conviction
Leak detection
Leaks become visible at the scale of a day.
A dense hydraulic mesh, continuous acoustic listening, real-time pre-location. Hover the sensors, run a scan: the data makes the network visible.
The principle
One common platform, capabilities on demand.
Every function lives in a single sensor. You activate (and pay for) only the capabilities that matter, where they matter: quality and hydraulics in contact with water, hydraulics alone on a pipe, metering at the delivery point.
The sensor
A 55 mm disc. Four formats. Every capability.
A common electronic core (electrochemical signature sensing, ultra-low-noise acoustic listening, embedded analysis, LoRaWAN radio), declined according to the point in the network and access to water.

Module · dernier mètre
Decentralised filtration
Treat water at the last metre.
Beyond monitoring, the tap module carries decentralised filtration at the point of use: securing drinking water where it is consumed, without relying on centralised treatment alone. A response of sobriety and resilience.
At the point of use
Treatment moves closer to the user: school, remote hamlet, tertiary site, home.
Resilience
Extra security in case of an incident on the network or the resource.
Sobriety
Secure drinking water where it matters, without over-treating the whole network.
Compact & autonomous
Tap module on a long-life battery, replaceable by the user in seconds.
Sovereignty
The data belongs to the authority. Without captivity.
Standard LoRaWAN protocol: the exact opposite of a proprietary remote-reading. Data owned by the authority and portable at any time, AI models placed in escrow, hardware as an interoperable returnable asset.
Open protocol
Standard LoRaWAN, integrable into the public network.
Data ownership
Returnable assets, portable at any time.
Models in escrow
Code & AI deposited in escrow, reversibility guaranteed.
Compliance
Approach aligned with ANSSI / CNIL recommendations.

Design office
Also an engineering team, beyond our own platform.
Electronics, embedded systems, Edge AI & embedded AI, instrumentation, IoT, data, water treatment: the same competence that built our sensor is available for your projects.
Deployment
From pilot to roll-out, in controlled stages.
No big bang. We instrument one sector, measure in real conditions, then extend, at the pace of your network and renewal programme.
- 01
Scoping
Technical workshop: perimeter, objectives (yield, quality, remote reading) and priority instrumentation points.
- 02
Sectorised pilot
Deployment on a real sector, in operating conditions, connected to VizO and your tools (CMMS, GIS).
- 03
Measurement
Field evaluation of performance: leak detection, quality vigilance, data reliability.
- 04
Roll-out
Controlled extension to the rest of the network, integrated into your regulatory renewal programme.
Ecosystem
Backed, labelled, supported.
Partners, institutional support and labels.
Frequently asked
What we get asked.
No. The sensor fits into the regulatory renewal programme and, on a large share of the fleet, through a simple head change, not the whole meter.
Yes. Standard LoRaWAN protocol, data owned by the authority and portable at any time, AI models deposited in escrow. No captivity.
No. It provides sentinel vigilance and directs accredited (COFRAC) analyses; the laboratory remains the regulatory arbiter.
In stages: a scoping workshop, a sectorised pilot in real conditions, performance measurement, then controlled generalisation.
Yes. VizO exposes open APIs (REST, MQTT, JSON, CSV) and interfaces with CMMS, GIS and telemetry.
