Sewer level sensors provide early warning to potential blockages and overflows. Operational teams can address blockages before they become costly overflow events that impact on public health, cause environmental damage and can quickly ruin a Councils reputation.
Monitoring sewer levels helps to:
- Avoid possible blockages with early alerts resulting in the reduction of costly overflow events
- There is improved insight gained on the relationship between duration and intensity of rain and the flows (and overflows). Such insight can help direct investments such as I&I inspections and sewer relining to areas with the highest potential for return on investments.
- Increased understanding of the sewer network performance
- Reduce wasted time and resources identifying and resolving overflow events
- Identification of the build up of debris in parts of the networks enabling targeted maintenance for better network performance
- Better workforce planning in both dry and wet weather events
Sewer network management
A wide range of information is now available with the use of low cost IoT Sensors and Networks, subsequently we can get a clear picture of what is happening across the Sewer System. Alerts to abnormalities and preset parameters indicate problems significantly speeding up response times.
Factors affecting the operational reliability of the sewer network includes the status of the pipework, broken or aging pipes, build up of debrie, root intrusion and environmental impacts from rainfall and rising groundwater.
We can now monitor the sewer network and quickly identify potential overflow events particularly when in relation to heavy rainfall events.
From the sensor through all stages of processing and analysis in Taggle’s Aqualus Vision software, Taggle has the complete solution to manage your network.
Alternatively the data can be sent to existing SCADA or other data delivery services as Taggle’s solution is open and interoperable.
Using data in Aqualus Vision for sewer network management
Pair level sensors with rain gauges
Improved sewer network understanding in different climatic events provides valuable insights as to when problems may occur. This allows for better workforce planning in both dry and wet weather events to maintain the sewer network.
The data collected provides improved insight on the relationship between duration and intensity of rain and the flows (and overflows). Such insight can help direct investments such as Inflow & Infiltration (I&I) inspections and sewer relining to areas with the highest potential for return on investments.
The impact of rainfall and rising ground water on sewer levels can be identified
Depending on the amount of data required, Taggle provides two types of level sensors
Ultrasonic or Radar
These devices provide granular data, every 15 minutes, of water level rises.
The data can inform as to where any weaknesses and build up of debrie in the network are, allowing crews to target clean-up and maintenance activities.
This predictive approach has the potential to optimise maintenance costs across the network by reducing clean-up and costs related to unnecessary maintenance of assets.
These low-cost sensors which are activated as the water rises in the chamber provide a cost effective early warning system to over flow events.
When used as a dual float system, the first warning alarm goes off as water levels begin to rise, the second alarm is set to when an overflow event is about to occur.
This enables the utility to proactively dispatch cleaning crews to investigate and clear any chokes before they result in wastewater overflows affecting customers or the environment.

MRC was the first to adopt Taggle’s smart sewer solution utilising the dual float system. The project subsequently resulted in better control, monitoring and reduction of discharges to the environment.
A combination of 88 flow and level sensors and one weather station installed in various parts of the Adelaide foothills suburb have, in the past 12 months, detected an prevented ten potential sewage overflows.
