For a long time, sanitation, whether public or private, was operated essentially in person. Monitoring systems depended on constant visits, manual records, isolated spreadsheets and often the memory of experienced operators.
This model worked for decades, but began to show clear limits in the face of more complex operations, stricter regulatory requirements and the growing need for operational efficiency.
It is in this context that remote monitoring is no longer a differential but a strategic tool for modern sanitation.
What is remote monitoring in sanitation?
Remote monitoring is the ability to track, record and analyze operational data from water and wastewater systems remotelyin real or near-real time, from different sources of information.
These sources may include:
- Manual readings taken by operators in the field
- Existing spreadsheets and historical records
- Automation and SCADA systems
- IoT sensors and devices
- Laboratory reports and quality indicators
More than just “seeing data from a distance”, effective remote monitoring organizes this information into a logical flowallowing managers, supervisors and operators to have a clear view of the operation, regardless of where they are.
Operational control: from reaction to predictability
One of the main benefits of remote monitoring is operational control.
In traditional operations, many decisions are made reactively:
- A parameter goes out of bounds
- The problem is noticed late
- The team rushes to correct
- Documentation comes later – when it does
With structured remote monitoring, the scenario changes:
- Readings are recorded in a standardized way
- Operational limits are continuously monitored
- Deviations generate alerts and automatic records
- The operation now has a history and traceability
This reduces improvisation, reduces dependence on specific people and increases the reliability of operational data.
Decision-making based on data, not assumptions
Another direct impact of remote monitoring is on the quality of decision-making.
When information is scattered, partly on paper, partly in spreadsheets, partly in isolated systems, the manager makes decisions based on incomplete snapshots of reality.
By centralizing operational data, remote monitoring makes it possible:
- Compare periods, shifts and operating conditions
- Identify trends before they become problems
- Evaluate the impact of corrective actions
- Prioritize interventions based on real data
Decisions are no longer based on “feeling” or momentary urgency, but on guided by evidence.
Operational efficiency and reduction of invisible costs
Efficiency in sanitation is not just linked to consumption of inputs or energy. It also involves less visible costs, such as:
- Time spent collecting and consolidating information
- Rework due to lack of standardization
- Communication failures between operations and management
- Difficulty of auditing and technical proof
Remote monitoring contributes to efficiency:
- Reduce unnecessary travel
- Automate records and consolidations
- Facilitate communication between teams
- Organize technical and documentary history
The result is a leaner, more predictable and easier-to-manage operation.
Remote monitoring is not just about IoT
An important and often misunderstood point is that remote monitoring does not depend exclusively on IoT or advanced automation.
In practice, many operations:
- They still use manual records
- Work with consolidated spreadsheets
- Partially automated
- They are at different levels of digital maturity
A good remote monitoring strategy adapts to the reality of the operationintegrating what already exists and allowing for gradual evolution.
The gain comes less from the technology itself and more from organization of the information flow.
The role of digital platforms in modern sanitation
Digital platforms specializing in sanitation have emerged to fulfill exactly this role: connecting operational data, people and processes.
They allow remote monitoring:
- Structured
- Traceable
- Auditable
- Evolving
More than just “seeing data”, the aim is to turn information into management and management into operational efficiency.
Remote monitoring in practice: the case of supply revitalization in Belém (PA)
A concrete example of the strategic application of remote monitoring is EP Group’s participation in the revitalization of the water supply system in Belém (PA), in partnership with Aegea, one of the country’s largest sanitation concessionaires.
See Case
The project involved the supply of 25 automatic filtration systems to remove iron and manganese, with a total flow rate of 4,400 m³/h.
To ensure continuous control and operational safety, the project implemented STEPEP’s proprietary remote monitoring platform.
With STEP, the dealership can now monitor the situation in real time and directly via cell phone:
- Filter operating pressures
- Valve status
- Filtration and backwashing cycles
- Performance indicators
- Occurrences and anomalies
The system automatically identifies operational deviations and sends immediate notifications via WhatsApp to those responsible, reducing response times and increasing the reliability of the operation.
In addition, the complete history of occurrences is recorded on the platform, enabling traceability, the generation of technical reports and support for audits.
In a project with 25 distributed units and hundreds of tons of filter media involved, remote monitoring has become a central element in ensuring efficiency, operational safety and predictability on a large scale.
Get to know STEP
STEP is an application designed for real-time remote monitoring of operations.
With 8 years on the market and around 35 industrial clients in Brazil – it stands out as a specific digital solution for managing effluent and water treatment plants. Developed by the EP Tech unit of the EP Group, the platform incorporates software and Big Data O&M (operation and maintenance) services for treatment systems. Its modules include:
- Parameter readings (manual and via IoT) – allowing real-time monitoring of process indicators;
- Cockpits and Dashboards – macro view of the plant, trend graphs and operational KPIs;
- Tickets and Tasks – management of occurrences, non-conformities and maintenance/correction activities;
- Stock of Supplies (Products) – control of chemicals and materials used;
- Projects and Minute Book – monitoring improvement projects and recording operational occurrences/decisions;
- Reports – generation of detailed reports, meeting the demands of environmental compliance and internal management.
Conclusion
Remote monitoring in sanitation is not a passing trend, it is a direct response to the current challenges of operation, compliance and efficiency.
When well implemented, it:
- Improves operational control
- Increases the quality of decision-making
- Reduces hidden costs
- Prepares the operation for a more predictable future
Regardless of the station’s level of technological maturity, the first step is always the same: organize the information so that it works in favor of the operation.
Is your operation prepared to move away from reaction and operate predictably?
