Sewer overflow
Monitoring &
Alarms
Scenario
o Every water authority has the
challenge of preventing sewer
blockages and spills  and
cleaning up when it happens.
o Spills and response times are
important KPIs for ESC
Reporting.
o Clean ups are expensive and can
have significant impact upon
customers, community and
environment.
Scenario
o Cost anywhere between $5K
and $200K for spill clean up.
o SE Water wanted to perform
better in these areas.
Business challenge
Improve Performance
Against KPIs
o Minimise environmental impact of spills from sewer.
o Provide warning that sewer level is rising  enable rapid response
and activate field crew before a spill.
o Cost effective and simple solution.
o Supplement other programs (e.g. Cleaning / Jetting / CCTV).
o Reliable in our sewer environment.
o Easy to implement / install.
Business solution
o An alarm device which communicates direct to SCADA system.
o Easy to install in manholes without requiring confined space
entry.
o Cost effective for widespread application  low maintenance.

o Reliable alarm device resilient to aggressive sewer environments.
Technical solution BlokAid
o All in the hole device.
o 2 way communicable device
using mobile telephony.
o Long battery life  10 years.

o Sewer Grade  entire
product.
o Communicates via SMS /
Email / direct to SCADA.
Benefits realisation
o Have 180 installed for SE Water.
o Respond to 100 alarms per year.

o Decreased spills from manholes by 25%
(Saved approx $1 million in clean up / insurance).
o Supplements cleaning program.

o Used in perceived high risk or multiple spill sites.
Case study
Public Utilities Board 
Singapore
o Significant rain events.
o Stormwater infiltration very high.
o Number of high profile spill / flood events.
Case study
Public Utilities Board 
Singapore
Purchased 950 devices and have installed over 800.
o Using 3 float device to give basic modelling functionality.
o In most cases PUB do not react until 2nd float is tipped.
o Gaining greater understanding of impact of heavy rain on their
sewer environment.
o Improved planning leading to reducing stormwater infiltration.

o Reducing spills in high profile areas.
Further development
o Intrinsically Safe Certified.
o HCB Float.

o External Antenna Option.
Water solutions
for a better
future.
