Why do you need the Greywater
alarm system?

Water utility & Industrial companies, and wastewater plants protect public health, production continuity, and treatment process stability with Greywater. Easy setup and affordability are key.

Before…

  • Absent or insufficient sewer monitoring system

  • Overspending on emergency repairs & cleanup

  • Sleepless nights, bracing for overflow disasters

  • Uncertainty paralyzing planning and operations

  • Lack of data for proactive network management

  • Critical assets at the mercy of wastewater flows

After Greywater

  • Zero overflows even during peak flow events

  • Operations teams are always ahead of problems

  • Preventive measures keep collection systems flowing

  • Investments on track, public health protected

  • Communities trust utilities’ proactive stewardship

  • Compliance costs stay minimal with early detection

Dangerous manual inspections are too costly & infrequent

We’re reimagining what wireless systems can and should do. These are the top ways our customers use them.

Protect public health

Communities depend on reliable sewer systems. Our smart sensors prevent overflows that contaminate water sources through early warning alerts.
