Sewers - Aqua Robur Technologies


Increasing regulations around sewer overflow and extreme weather pushes the need of remote monitoring of sewer networks. By monitor your wastewater and stormwater networks with Aqua Robur’s Plug & Play solutions you can reduce your problems related to overflow, infiltration and inflow.

The Problem

For many utilities, up to two thirds of the treated wastewater is infiltration water or inflow from combined sewers. This significantly increases operating costs but also capital expenditures as unnecessary investments in new treatment capacity has to be added. Another problem besides treating too much wastewater is that large quantities of sand and other particles can enter the pipes. This wears them down, decades before their service-life is expected to end.

Further, large quantities of untreated wastewater is released into the nature, where utilities are often unaware of the extent of the problem and where to focus their resources to reduce the problem.

How we help you solve it

By measuring the water level with the accurate and contactless LS-7389 level sensor, you get the full picture of the behavior of your wastewater network and the problems of overflow, infiltration and inflows. 

Further, the Fenix Hub provide you automated calculations of volume flows in the wastewater- or stormwater networks.

The best part; the system is Plug & Play with minimum effort for installation. No need for electricity or complex antenna solutions outside of the well.

You can also improve your analysis by comparing water levels with rain sensor data.


Contactless and waterproof

The LS-7389 ultrasonic level sensor ensures trouble-free maintenance as it is not in contact with the water. The components for the sensor and sensor hub are IP67 classified. The bracket is electro galvanized, with stainless steel as optional.

Energy efficient

The battery-lifespan is dependent on the sensor and radio intervals. In a typical configuration for CSO-monitoring the battery will last around 2 years. When deploying sleep mode, this can be extended to more than 5 years. Batteries are easily replaced in a couple of minutes.


Get notified when you need to take action. Decide when the system should send alarms. For example the system can send alarms when a threshold level is reached or when when an overflow is about to take place.
