THE LIVING WEB - OVERVIEW
Historically the monitoring of CSOs has been a box-ticking exercise. The EA and SEPA look to the Utilities to come up with a strategy for recording spills, and to report accordingly. In recent years, many water companies have tended to adopt the 'black box' solution. This involves a single downward-looking ultrasonics sensor which will alarm when a certain level is reached. This is all very well when looking at CSOs in isolation, however it doesn't really address the underlying causes of CSO spills and the appropriate response. In OnSite's view, ultrasonics technology can be problematic, and can often give false alarms due to spiking etc. Also, they only provide the user with depth, and no consideration is given to whether the flow is going forward, standing still, or backing up. This can have a fundamental effect on operational and engineering strategies.
Through OnSite's extensive experience with short-term flow surveys, we have identified the need for more accurate, reliable, and timely data. We have also concluded that long term/permanent monitoring of sewer networks (primarily CSOs) needs to be carried out more intelligently, adopting a joined-up approach. We have been looking for a solution which provides real time access to data, and sensor redundancy to enhance data return. Consequently we have been carrying out R&D for the last 12 months, and have recently launched what we believe to be the ideal solution for both short-term and long-term sewer flow monitoring – the OS Series of flow monitors and rain gauges, and the Living Web software platform.
