For facility managers, property owners and water service providers
Water data at every point of use. Under 30 minutes per point, no plumbing work.
Find leaks before they show on the bill, clean washrooms when they are actually used, and service fountains and filters when they need it. Droople sensors fit on your existing taps, toilets, showers and water machines, and tell your team where to act.
Free water review: share usable water data and get a written answer within 2 business days.

See it in action
What teams see when water is connected
How it works
Connect. Understand. Act.
Fit sensors on what you already have
Small sensors clip onto existing pipes and equipment. They send data on their own network: no Wi-Fi, no IT project, no plumbing work.
See what each water point does
How much water each tap, toilet or machine uses, when, and what changed, building by building.
Give teams a next step
An alert when water runs where it should not, a cleaning or service task when it is needed, and a report you can share.
Evidence from real projects
Measured results, a clear basis for decisions
Results relate to the projects shown; outcomes depend on the site, assets and actions taken.
