Overflow registration and reporting
There is a growing problem with overflow from the jointly drained drainage systems. The number of incidents in which rainy outflows are affecting streams with organic matter, among other things, must be closely monitored in order to be able to assess whether in the future there is a need to sharpen efforts to reduce the number of incidents further. The objective is to map overflows from sewers to a sufficient level, to demonstrate whether the given discharge permits are being met. In addition, the purpose of the mapping of overflows is to obtain a clear basic knowledge of the quantities of water and matter that are derived from the individual overflow constructions. (cf. DHI Best Practice for mapping and reducing overflow from jointly drained drainage systems)
For several years, Danova has developed a battery-powered data logger for this purpose, which collects data and can automatically report the number of overflows, the duration and the amount. In addition, external sensors can be connected to register the substance to be measured. From the data server you can configure a report that contains the data and measurement points you want to include in automatic reporting.
D-Eye has been developed to supplement the measurements in the overflow itself, with a picture of the overflow. It is now possible to get a picture of the overflow when it happens, as well as to log on and manually take a picture of the overflow construction when you want. For example. before sending out a crew to clean the overflow and grates.
The first customer: Frederikshavn Forsyning A/S, was the first to install the system in 4 strategic locations. Frederikshavn Forsyning A/S chose to have Danova® install the flow meters and at the same time set up the data registration, at onlinedata.danova.dk – Danova’s online server.
