mWater vs AQUARIUS

Short answer: These products overlap, but they are designed around different primary jobs. The right choice depends less on a feature checklist than on the data model, users, workflows, and operating environment you need to support.

mWater connects offline field collection, mapped sites and assets, monitoring rounds, indicators, dashboards, and work management. AQUARIUS by Aquatic Informatics is specialized software for acquiring, correcting, quality-controlling, analyzing, and publishing environmental and hydrological data.

At a glance

Requirement	mWater	AQUARIUS
Primary strength	End-to-end WASH and service monitoring	Defensible environmental time-series data
Data model	Surveys linked to persistent sites, facilities, people, and assets	Monitoring locations, parameters, time series, samples, and derived values
Field operations	Offline surveys, assignments, approvals, issue tracking, and asset workflows	Specialist environmental field data and connected monitoring systems
QA/QC	Validation rules, approvals, cleaning, audit history, and configurable workflows	Advanced time-series correction, rating curves, automated checks, and audit trails
Access model	Free core platform with unlimited users; optional services	Commercial products including managed cloud options

Choose mWater when

You are building a WASH MIS, facility registry, utility asset system, household survey, or recurring inspection programme.
Many field and government users must collect and use data on ordinary mobile devices, including offline.
You need one environment for questionnaires, maps, indicators, dashboards, permissions, issues, and workflows.
You need to start without buying user licences for the core platform.

Choose AQUARIUS when

Your work depends on continuous environmental time series from monitoring stations and sensors.
Hydrologists need rating curves, flow derivation, corrections, data grading, traceable QA/QC, and publication-ready outputs.
Real-time flood, water-quality, groundwater, or water-availability monitoring is the dominant use case.
You prefer a purpose-built commercial platform and associated implementation and support.

Where the distinction matters

A questionnaire that records whether a borehole works is structurally different from a stream-gauge series sampled every few minutes. mWater is strongest at the first kind of problem and at relating repeated observations to facilities and services. AQUARIUS is strongest at the second and at the specialist transformations that turn raw environmental measurements into defensible hydrological records.

Can they work together?

Yes. AQUARIUS can remain the system of record for sensor and hydrometric data while mWater manages facility inventories, field inspections, programme indicators, and action workflows. An integration can bring approved summaries or alerts into mWater, or send field observations to the environmental system. Define ownership, units, time zones, quality flags, and update frequency explicitly.
