Sewer Level Monitoring and Analytics

Objective

To identify, in real time, any Combined Sewer Overflows or sewers that are either discharging or operating at a high level when they would not be expected to considering the local rainfall. Aim to be to identify ‘dry weather’ discharges or sewer blockages as soon as possible and to make the information as useful as possible by excluding the impact of rainfall.

Details

Real-time radar rainfall data at 1km2 pixel size covering the entire Water Company’s area is aggregated into the catchment area for each discharge point or sewer. This rainfall data is combined with real-time alarm data from the Water Company’s telemetry systems to determine if the discharge is due to local rainfall or is a ‘dry weather discharge’.

All this information is made available via a management mobile-friendly dashboard, built using the Meniscus Analytics API. This same API can be used  to integrate data back into the telemetry system.

A range of management reports can be e-mailed out on a scheduled basis to summarise key events.

Benefits of using MAP

MAP makes it possible to combine rainfall data over a large area with corporate datasets on asset performance. This enables the creation of a range of easily customised calculations to determine the operational characteristics of these assets (in this case whether they are discharging or at high level during periods of no rain). Creation of the CSO and Sewer Level Entities and the associated calculations is automated once the initial Entity templates are approved.
