Project Description

This case study explores a collaborative project between the City of Banyule in Melbourne, Australia, and Minnovation Technologies to monitor the utilization of 42 remote public bathrooms using infrared technology. The initiative aimed to gather data on the number, timing, and frequency of usage for male, female, and disabled facilities independently. The primary goal was to assess the necessity of these facilities and optimize cleaning schedules for resource efficiency.

Project Overview

The primary objective was to determine the actual usage of public bathroom facilities to optimise maintenance and cleaning frequencies. The project involved installing infrared sensors in male, female, and disabled bathrooms, independently measuring the number of users, time of day, and frequency of use.

Collaboration and Technology Selection

Minnovation partnered with the City of Banyule to select the appropriate technology and network infrastructure for this project. Infrared technology was chosen for its accuracy and non-intrusive nature, ensuring privacy while collecting essential usage data.

Data Architecture and Network Infrastructure

Considering the widespread locations of the bathrooms, the data architecture was designed to handle information from remote areas efficiently. A robust network infrastructure was established to ensure seamless data transmission from all facilities to the central monitoring system. this infrastructure was based on the public LoRaWAN network that is supported by the City of Banyule.

The project included the expansion of this network from 9 to 16 gateways.

Implementation and Monitoring

Infrared sensors were installed in male, female and special needs public bathrooms across 42 remote sites. These sensors provided valuable data on the utilisation patterns of these facilities, including peak usage times and frequency. This data was crucial in determining the need for each bathroom and planning the cleaning schedules effectively.

In addition to the cleaning rosters, maintenance and planning teams were better able to determine maintenance requirements and capital replacements based on the knowledge provided by the sensors.

Results and Impact

1. Optimised Cleaning Schedules: The data enabled the City of Banyule to adjust cleaning frequencies based on actual usage, ensuring resources were used efficiently.
2. Resource Management: The project identified bathrooms with low usage, aiding decision-making about their necessity and maintenance.
3. Improved Public Service: By aligning cleaning schedules with usage patterns, the project ensured better maintenance of public bathrooms, enhancing community satisfaction.


The collaboration between the City of Banyule and Minnovation Technologies in using infrared technology to monitor public bathroom usage represents a significant step in municipal resource management. The project successfully provided data-driven insights, leading to more efficient use of resources and improved public services.
