4. • Drainage systems corrode, erode, clog, collapse and ultimately deteriorate to
the point of failure. Reactive maintenance cannot reduce the number of
system failures.
• Specific exfiltration locations are insignificant. The value is in try to mitigate
the after math such as flooding, ground and water source contamination, road
collapses and infiltration locations.
• Creating a condition assessment map using the return signal of wastewater
can give valuable information on the network’s deficiency level on a segment
basis. Visualizing the entire network assists with decision making processes
for pipe and channel replacement or deployment of teams for inspection and
repair.

10. Scaling a Sewage Monitoring Program
Correlation with existing data:
Customer data includes multiple parameters and ASTERRA is SAR only
Conclusion:
There are reasons for the discrepancies but the trend
is clear
CCTV cost per KM is 6,500 euro – save on
verifications and prioritize deployment
