Monitoring CSO's helps prevent flooding and reduce pollution

CSO monitoring

In a combined sewer, wastewater from homes and businesses amalgamates with surface water and carries it to the treatment works. In periods of heavy rainfall, a combined sewer overflow (CSO) diverts excess flow to prevent flooding upstream.

The consequence of a CSO is that untreated wastewater is released into the environment, which could have an adverse effect on the environment, polluting rivers and streams and increasing the risk to human health. It is vital that water companies carry out CSO monitoring programmes to understand what is happening.

Detectronic works with water utilities companies to monitor CSOs, helping to prevent flooding and reduce pollution. We use a combination of flow monitoring, level monitoring and near real time data analytics to deliver smart network monitoring solutions.


Level monitors

When level monitors are placed strategically around the sewer network and in combined sewer overflows, they transmit level information, via GPS, to the Detectronic Data Centre, where it is analysed automatically, in near real time. If the water level at any sensor-monitored point exceeds preset parameters, then an alarm is raised to the appropriate water authority. The authority then takes appropriate action to alleviate the situation.

Flow meters

We place flow meters across the sewer network to help understand the performance of the network regardless of what is happening with the weather. The insight provided helps the water utility company manage their network and plan repairs and upgrades accordingly.

The MSFM flow meter range records data from three sensor inputs. Information on the level, velocity and Aux Level (CSO) readings can be taken at regular intervals between 1 and 60 minutes. This is then sent to a host computer via SMS or GPRS at a user-selectable frequency (typically once a day, once a week or once a month). For sites requiring Environment Agency accredited equipment, we have the MCERTS MSFM available.

Event Duration Monitoring (EDM)

As a result of urban growth and changes to climates and landscapes the pressure on CSO’s is likely to increase. By understanding what is happening at a combined sewer overflow spill event, water companies can use the data to understand how the network is performing and influence sewerage planning activities.

By integrating EDM into CSO monitoring programs, water companies will be able to protect the performance of CSOs, address frequently spilling overflows and identify risk.
