Failures in sewer systems are a major cost to Water and Sewerage Companies (WaSCs). The number and impact of failures can be reduced by rapid intervention which requires control room staff to have an integrated view of network performance. This would allow decisions to be made based on the consequence and impact of a failure taking into consideration climatic conditions such as rainfall.
To develop more effective control room solutions WaSCs need to identify the information that would improve decision making and plan implementation of technologies that could deliver this information.
Dealing with sewer flooding and pollution incidents costs WaSCs over £40 million per year. Even a modest 10% saving achieved through improved network control would translate to a saving of £4 million. Improvements in SIM score would also be achieved through reduced customer impact of sewer failures.
The project will review incidents that are reported via telemetry alarms and from customer contacts together with interventions that could be taken to prevent or mitigate the impact of service failure. Static and real time data requirements to make optimum intervention decisions would then be identified.
Monitoring, modelling and communications technologies and data analysis techniques available to deliver this information will then be reviewed and gaps identified. An implementation plan to fill technology gaps and to move from current control room technologies to the new approach will be developed.
Identification of data requirements for optimum decision making is the first step towards implementing the technology that will deliver more integrated and comprehensive information. The implementation plan will highlight any pitfalls and serve as a basis for a business case.
