The document discusses the challenges of preventing sewer blockages and spills faced by water authorities, highlighting the importance of monitoring and response times. It introduces a cost-effective alarm device called Blokaid that communicates with SCADA systems to provide early warnings about rising sewer levels, resulting in a significant reduction in spills and related cleanup costs. Case studies demonstrate the successful implementation of this technology in various authorities, including a significant partnership with the Public Utilities Board in Singapore.

- 2. 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.
- 3. Scenario o Cost anywhere between $5K and $200K for spill clean up. o SE Water wanted to perform better in these areas.
- 4. 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.
- 5. 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.
- 6. 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.
- 7. 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.
- 8. Case study Public Utilities Board – Singapore o Significant rain events. o Stormwater infiltration very high. o Number of high profile spill / flood events.
- 9. 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.
- 10. Further development o Intrinsically Safe Certified. o HCB Float. o External Antenna Option.
- 11. Water solutions for a better future.
