manhole sensors

Create 24/7 monitoring tools with

our low-cost distance sensors 

Convert manhole lids

into super smart sensors 

Reduce costs, protect assets, prevent pollution and help to save lives and property damage

Monitoring sewer manholes in real time can provide significant benefits to water utilities by helping them to detect and prevent sewer overflows, reduce treatment costs, improve operational efficiency, and comply with regulatory requirements.

Australian company TracWater, supplies the TracNet manhole sensors and cloud based TracNet systems. TracNet is used by water utilities to monitor sewer and stormwater manholes to help prevent sewer overflows by identifying blockages, leaks and other issues before they cause a backup or overflow.

When sewerage and stormwater manholes overflow they can contribute to  polluted run-off, which can contaminate  local waterways and harm aquatic  life. Monitoring sewerage and stormwater manholes can help to identify potential sources of pollution and prevent contamination.

Cloud Data Management:-
TracWater TracNet IoT Cloud

TracWater IaaS user-interactive high-speed  cloud data system including alerts and alarms.

Get SMS and email alerts and alarms for sewerage spills, manhole lid tilt, rising sewerage or storm water levels under manhole lids, illegal opening or dumping of liquid waste etc.

Includes TracNet cloud portal access, sensor installation app for fast 5 minute installation and up to 3-5 years of sensor battery life communications.

TracNet sensors are geo-mapped with status and live update of measurements for distance, manhole lid tilt angle, temperature, communications and power.
