Wet-well level, pump behaviour, gauges, the control panel and the electricity meter, read in place at a set interval by battery-powered sensors fitted to what is already there. No cabling, no SCADA project, no station taken out of service.

Customer story
See the water & wastewater pageA regional water and wastewater utility with thousands of water inlets to keep clear of debris and within their levels, spread across the region and worst to reach in the weather that matters most.
We have a good collaboration with Waltero, and their product has already provided significant benefits to our operations at an early stage. Our team is now able to perform visual inspections from the office instead of having to drive out to the monitored facilities.
John Hägg Development Engineer, VA SYD
Water inlets across the region had to be inspected for debris and water level on scheduled rounds. Every check was a trip, the rounds were longest in bad weather, and a blockage between two visits was found by its consequences.
Questions
See the water & wastewater pageThe questions operations and maintenance teams ask before a first station, answered the way we would answer them on a call.
A pump station lifts water or wastewater so it keeps moving towards storage, the network or the treatment plant. Most utilities have many of them, spread out, and the smaller ones are often not connected to SCADA at all. Between visits a rising wet well, a pump that has stopped or a valve left in the wrong position is found by its consequences: an overflow, a complaint or an emergency callout. Monitoring turns those visits into readings taken at a set interval, so the station is known between rounds.
It is not a replacement for either. SCADA covers the stations it is wired to, and the instruments wired into it. Waltero covers what is read by hand: the stations that were never connected, and the analogue gauges, meter registers and panel displays that sit outside SCADA at the ones that are. Readings can be pushed into SCADA, the historian or a maintenance system over REST or MQTT, so the two sit side by side.
Yes, and that is the typical case. A W-Sensor is mounted over the gauge, meter or display and reads it with a camera and on-device AI at the interval you set. Nothing is wired into the panel and nothing joins its network, so there is no PLC tap and no integration project; the sensor reads the instrument the way a technician does.
It learns a fingerprint of how each dry-mounted pump normally runs: when it starts, how long it runs, and what its vibration looks like while it does. From that it reports run events and run hours, trends over time, and an alert when a pump deviates from its own baseline. It is a fingerprint and a trend, not a predictive-maintenance model: it tells you that a pump has changed, and your engineers decide what that means. Submersible pumps carry no sensor and are judged by the wet-well level and the control panel instead.
No. Each sensor reads at a set interval, hourly by default and from every 15 minutes to once a day, and sends the reading with the image behind it. Readings in Mimir are up to date as of the last interval, which is what the battery life, and the price, are built on.
A W-Sensor is mounted on the instrument with the matching adapter, paired from the installer app and reporting on the next interval; a point takes minutes and no station is taken out of service. It runs on replaceable batteries, 10+ years with the recommended batteries depending on reading frequency and connectivity, and connects over LTE-M or NB-IoT, so there is no gateway, no site network and no power at the station needed.
The scheduled visit whose only purpose is to read something goes away: the level, the gauges, the meter and the panel are read at a set interval and logged automatically, with a photo behind every reading. Crews drive out when a reading calls for it. At VA SYD, monitoring water inlets by camera cut on-site inspections by 66 percent; a pump station round has the same shape.
Next step
Every utility already has the answer written down: the list of stations, and what gets read at each of them when a technician drives there. One conversation about that list tells us exactly which readings we can take over for you. The checklists above are a good place to start.
