This document describes Fracta's artificial intelligence and machine learning solution for assessing water main condition and predicting pipe breaks. It provides an overview of Fracta's 3-step implementation process, features such as likelihood of failure and consequence of failure scoring, and advantages such as providing faster and more accurate predictions than satellite-based solutions. It also presents a case study showing how Fracta helped a water utility identify 75% of hidden leaks, saving 20% in non-revenue water loss.

Fracta Features
CoF determines the
consequences, or severity, of the
water main failure and quantifies
the direct and indirect costs of
those failures.
Job Planner is the perfect tool for
modelling the maintenance and
operation costs on a specific area
of the water network.
Job Planner allows to schedule
and follow-up the repairs as a
project management tool.
Likelihood of Failure (LoF) Consequence of Failure (CoF) Job Planner
High LoF = High breaking probability High CoF = High € to replace
Total Risk combines LoF and COF
to determine if a pipe is worth
replacing.
High TR = High BP or €
Total Risk
Smart and digital solution which
brings new value by predicting
and preventing disruptive water
leakages or network breaks in the
water distribution

Advantages of Fracta
Constant Improvement
Fast
• No hardware need
• Accept any format of
pipes and break history
data
• Results come in after
few hours
• Results can be updated
whenever desired
• New features
improvements regularly
• AI & ML make the
results accurate
Fracta assesses the condition and risk of water mains and determines which pipes to
replace (and which to not replace).

Benefits of Fracta
Over 80 water utilities have used Fracta software along 300 000 km of pipes.
See case studies → San Francisco and Greater Johnstown Water Authority for more
information about NRW savings with Fracta .
✓ Reduce leakages and
breaks
✓ Plan and budget the
operations and
maintenance
✓ Targets the pipes that
need to be replaced only
and reduce NRW*.
Better Reactivity Less Time and Costs
*NRW: Non Revenue Water

Case study Greater Johnstown Water Authority
Results:
Within the first seven months of using Fracta,
GJWA was able to correctly identify 75% of
the hidden leaks in 15 pipe segments, saving
the utility 20% in Non-Revenue Water loss.
