Continuous level monitoring for sewer lines and manholes that helps utilities detect surcharging, blockages and overflow risk early.
Sewer systems carry out a service people rarely think about until it fails. When a line backs up or a manhole overflows, the consequences reach streets, homes, waterways and public health.
Sewer Monitoring from ToltHawk gives utilities a live view into the network, so conditions underground are known instead of guessed.
Most of a sewer network is buried, which makes problems hard to see. Utilities often find out about blockages or overflows from a resident’s call, by which point the damage has started. Heavy rainfall can push levels up quickly. Manual manhole inspections take time, can be hazardous for crews and only show conditions at the moment of the visit. Overflows can also cause environmental harm and regulatory consequences.
ToltHawk sensors can be placed at selected monitoring points to measure water levels and send readings remotely to the ToltHawk dashboard. When levels rise toward a configured threshold, alerts can notify your team so they can investigate and respond. Historical data can help identify network locations under repeated strain and focus maintenance efforts.
Installation note: Sensor type, manhole compatibility, mounting method and confined-space procedures should be confirmed for the specific site before deployment.
Collect level information remotely, set the alerts you need and review changes over time.
Select manholes and pipe sections with a history of surcharging, blockages or overflow risk.
Choose a suitable sensor and mounting approach for each location, with access and worker safety planned in advance.
Record water-level changes and send readings remotely to the monitoring platform.
Use configured thresholds for notifications and review historical patterns across wet and dry weather.
Thresholds below known critical levels can give teams an opportunity to investigate before an overflow occurs.
Unusual level changes can point to developing problems and help teams decide where to inspect.
Remote monitoring can reduce routine manual checks in hazardous locations.
Use measured conditions to help prioritize cleaning, inspection and repair work.
Historical readings can support operational reviews, documentation and compliance efforts.
Compare patterns during wet and dry periods to investigate possible inflow and infiltration issues.
Keep conditions visible at the locations where early information can make a difference.
Track collection systems across a service area and identify locations that need attention.
Monitor critical trunk lines and approaches to pump stations.
Support response planning and reduce avoidable emergency inspections.
Watch private sewer connections and selected discharge points.
Compatibility depends on the sensor configuration, manhole geometry, environmental conditions and required measurement range. ToltHawk should confirm the suitable sensor and mounting method for your site before installation.
Alerts can be configured around agreed level thresholds. Setting a threshold below a known critical level may provide time to investigate, but warning time depends on site conditions and how quickly levels change. Monitoring cannot guarantee prevention of every overflow.
Sewer and stormwater monitoring can be considered together to help teams understand how rainfall affects drainage and wastewater systems. Confirm the required sensors and dashboard configuration with ToltHawk for your deployment.
