Pump Monitoring & Predictive Maintenance

Pump Monitoring IoT solution: get real-time performance + maintenance insights that reduce costs.

The problem

Wastewater pumping stations are an intrinsic part of the sewerage network, raising sewerage from gravity-fed pits to extend transmission over longer distances. As such, they’re often located in built-up urban areas, operate regularly and can quickly cause problems when they fail.

What’s more, they’re also often ‘old infrastructure’ that have only been augmented over time with newer equipment as pieces fail, rather being continuously invested in and modernized.

In addition, there’s lots of machinery involved. This makes monitoring the sites’ pumps, extraction fans, and waste pits is an arduous and manual process full of inefficiencies requiring site visits by expensive resources, even when there aren’t any current or forthcoming issues.

Pump Monitoring IoT solution: monitor remote assets in real-time to improve performance, predict maintenance needs + reduce operational costs.

The solution

Our Pump Monitoring IoT solution, (built on our world-leading Dynamix integrated data, AI + IoT platform), was designed to collect real-time data using new flowmeters and power meters added to existing machinery in order to provide continuous performance metrics and maintenance insights. As pumps types vary, the solution needed to flexibly accommodate a range of equipment types in operation.

Defining what data to collect is critical
In order to create our Pump Monitoring IoT solution, we identified the key metrics required to achieve the desired business objectives. In this solution, this included:

  1. Waste pit levels
  2. Flowrate and totalized flows 
  3. Pressure on the inlet and outlet of the pump
  4. Pump power consumption
  5. Pump energy efficiency.

Initial goals of the Pump Monitoring IoT solution
Working with our partners, we installed flow meters and energy meters before connecting them via Modbus to a 4G gateway, so that we could then:

  1. Monitor critical operational data received from the equipment via a web-based system
  2. Ensure device management monitoring was set in place
  3. Define business logic for the application in-order to meet the business objectives
  4. Provide alarm and alert notifications via email or SMS messages
  5. Start collecting historical data to undertake pump efficiency modelling
  6. Provide the right dashboards to the right users with the right insights
  7. Test the application, making sure all of the above goals are met, based on the solution architecture.

Before go-live, we tested four critical aspects of the Pump Monitoring IoT solution:

The Rayven Dynamix data, AI + IoT platform is built with security as a top priority and our proprietary security architecture ensures that data is secure at all points of the environment.

The Pump Monitoring IoT solution includes data encryption in transit from device-to-cloud, as well as device authentication; security (Bearer) tokens; SSL, AES and RSA encryption; as well as additional device security checks done via automated polling.

None of the existing equipment was automated, and so a critical step in this solution was to add the right sensors, create local Modbus connectivity and install a 4G gateway to ensure a reliable, continuous real-time connection.

Data integrity
Your ability to make the right decisions is entirely reliant on the integrity of the data you collect, therefore, making sure that any  solution has reliable connectivity is key to ensuring your data is always up-to-date and that you can rely on it to make critical business decisions in real-time. However, things do go wrong, so with our Pump Monitoring IoT solution, it was critical for us to test that the data coming from the water facility matched that being shown on the dashboards and to build in capability to back-fill data in sequence in the event that any communication link ever went down, such as through a 4G outage.

Industrial data science
The objectives of the exploratory data analysis was to monitor pump-house performance and efficiency, which included:

  1. Calculating flow rate by minute, hour, day, and week
  2. Forecasting daily water flow
  3. Understanding pump utilization
  4. See pump energy efficiency (both whilst pumping and when idle)
  5. Leak detection with minimal false positives.

What’s next?

We are continuing to add additional pumps to the Pump Monitoring IoT solution and improve our maintenance forecasting results. In addition, we are planning to add real-time energy pricing to provide a more precise view of costs, as prices are dynamic during the day.

Key features of our Pump Monitoring IoT solution:

All of these features were customized to fit the customers specific business objectives.

Real-time performance monitoring

Old pump houses are virtually invisible to monitoring. Gain continuous real-time oversight of pumps, waste pits and extraction fans from a central location.

Alerts and notifications

Receive SMS and email alerts as soon as an event (e.g. a pump failure) or a critical threshold (e.g. waste pit level) occurs.

Waste pit monitoring

Continuously monitor waste pits to avoid overflows.

Energy efficiency

Understand the energy performance of pumps when active and when idle. Compare the efficiency of pump types or across pump houses.

Predictive maintenance

Use continuous real-time monitoring of pumps and pump flows to identify failing pumps before failure occurs.

Complete ongoing history

Compare and contrast performance, spotting trends and identifying weakness. With automated backfill, you can be sure that there are no gaps in your data set.

Remote monitoring of wastewater pump stations enabling predictive and preventative maintenance.

Delivering real-time business outcomes: our Pump Monitoring IoT solution.

settings-1 Lower cost of maintenance

Old infrastructure has a great tendency to fail and must be visually inspected. Sending crews out to pump houses is costly and time consuming. Remote monitoring of your assets is a much more efficient way to monitor and maintain your assets.

Better resource utilization Better resource utilization

Send crews to the right place, at the right time, with all the parts that they need to do an already understood job right the first time.

Less downtime Less downtime

Continuous monitoring means you can move away from fix-as-fail to a more proactive maintenance regimen, meaning less downtime and better outcomes for your customers.

Reduced energy consumption Reduced energy consumption

Monitoring pump energy consumption alongside of pump flow and total output provides you with insights about pump efficiency when running and when idle and allows you to compare efficiency across pumps and pump-houses.

Fewer maintenance calls Fewer maintenance calls

The solutions means fewer unnecessary visits and ensures that the root cause of problems are addressed, reducing errors and additional call-outs.

Greater predictability Greater predictability

You can understand how your assets are performing and the impact of 3rd part sources, enabling you to better predict expenditure across machines and sites.
