Leak Predictions

Leak Predictions

To accurately forecast when (both date and time) and where (to within a few metres) a pipe in the Potable, NEWater and Industrial Water transmission and distribution network might be going to leak.

Problem Statement

To monitor the condition of Mechanical & Electrical (M&E) equipment such as pumps, compressors, air blowers, centrifuges, switchboards, transformers with minimal manpower, at a lower cost (in terms of Capex and Opex) than current approach?

Background Context

At PUB, to ensure our water supply is running 24/7 sustainably, efficiently and serving our businesses and citizens continuously, we have to ensure our infrastructure and equipment are performing at its intended performance standards. 

Mechanical & Electrical (M&E) equipment such as pumps, compressors, air blowers, centrifuges, switchboards, transformers are deployed in areas like water & wastewater treatment plants, pumping stations, reservoirs, etc. 

The equipment immediate environment can be categorised as outdoor, indoor and also underground. 

They are subjected to high temperature variation, high humidity atmospheric condition, and possible environmental noise such as stray voltage, power surge and lightning transient.  

In addition, these field equipment are handling a variety of media, such as raw water, used water, treated water, aeration air and process sludges. 

In used water reclamation plants, the media may contain grit, debris and stringy matter, hence causing corrosion/damage to the equipment.

Current Practice & Approach

IOT Sensors – Online Temperature Sensor and Vibration Sensors are currently used to monitor the equipment conditions. 

A dashboard platform is used for monitoring and alerts when the equipment health indicators (whose intelligence is derived from the datapoints gather from an IOT sensor tracking a particular equipment) shows a differing status from the baseline norm.

Ideal Solution

An ideal solution should highlight to the Operation and Maintenance Team (Water Transmission and Distribution Department) when (by date and time ideally) and where (by pinpointing the location to within <5 metres ideally) a potential leak will occur, so that the necessary corrective action can be taken before the leak occurs

Minimise Downtime

Increase Equipment Availability

Restore Operating Performance and Efficiency upon Maintenance

What’s in it for the
solution provider?

Selected Teams during the Digital Water Programme may be invited to pitch to PUB Project Evaluation Panel (PEP) for test-bedding and pilot trial projects at PUB’s installations with potential funding support.

Solution that is subsequently verified and validated within PUB Test site, may have a clear plan to scale to other PUB sites.

Key Evaluation Criteria


Outcome-based: monitor enough parameters and data to consider maintenance regime that provides representative and accurate insights of the current condition of the asset.


Cost effectiveness against the proposed outcome


Cost competitiveness against existing solutions
