WATER ECONOMY Water infiltration monitoring
Reduction of operating costs, lower water pollution and improved settlement planning when using the ORS technology.
Water infiltration monitoring
External discharges in drainage systems lead to considerable operational problems of the plant (pumps, sewage treatment plant, etc.), to higher costs in urban drainage and can contribute to significant water pollution.
External water discharges are for example
- misconnections of rainwater pipes to sewers
- misconnections of sewers to rainwater pipes
- external water discharges in mixed and dirty water channels as well as in
- leaky and broken lines and channels.
The Optical Radar System (ORS)
The ORS system is optimized for the localization of external water discharges.
The measuring system consists of an optical radar in form of a datalogger and a fibre optic sensor cable. The sensor cable is pulled from the shaft into the mixed sewer system to be monitored and connected to the optical radar. The ORS system measures the temperature along the measuring cable with a local accuracy in the cm range and with a measuring time by seconds.
The use of the ORS system enables comprehensive monitoring of drainage systems in order to permanently counteract the discharge/infiltration of waste water and to avoid additional costs.

FAQ
What are Inflows and Infiltrations (I&I), and what problems do they cause in drain-age systems?
Inflows and Infiltrations (I&I) refer to unwanted or improper discharges of water into drain-age systems that are not designed to handle them. These inflows can lead to significant operational issues, such as in pumping stations or wastewater treatment plants. They also cause increased costs for urban drainage and can result in significant water pollution, negatively impacting the environment.
How can the Optical Radar System (ORS) help reduce costs in urban drainage?
The Optical Radar System (ORS) helps to precisely locate Inflows and Infiltrations (I&I), thus avoiding unnecessary strain on the drainage system. By detecting incorrect connections and leaks, costly overloads or upgrades to wastewater treatment plants and pumping stations can be avoided.
How does the Optical Radar System (ORS) detect Inflows and Infiltrations (I&I)?
The Optical Radar System (ORS) uses a highly precise measurement technique called Distributed Temperature Sensing (DTS). The system consists of a data logger (the optical radar) and a fiber-optic sensor cable. The ORS measures the temperature along the cable with high spatial accuracy in the centimeter range and records data at intervals of seconds. Temperature changes within the sewer can indicate Inflows and Infiltrations (I&I), allowing for quick and precise localization.
How complex is the installation of the sensor cable in a drainage system?
The installation of the sensor cable is relatively simple and does not require major modifica-tions to the existing infrastructure. The sensor cable can be inserted into the sewers from ex-isting manholes, for example, using a cleaning nozzle from cleaning vehicles, allowing for quick and straightforward deployment.
How reliable is the Optical Radar System (ORS) compared to traditional methods of Inflow and Infiltration (I&I) detection?
The Optical Radar System (ORS) offers higher reliability and precision compared to traditional methods. It provides continuous 24/7 monitoring over several weeks and delivers real-time data, allowing Inflows and Infiltrations (I&I) to be detected accurately at any time of day or night.
Is the Optical Radar System (ORS) suitable for use in all areas of our drainage system?
The Optical Radar System (ORS) is flexible and can be used in various parts of your drainage system, whether in combined sewers, stormwater, or wastewater sewers. It is particularly useful in areas that are difficult to access with other methods, providing a comprehensive solution for Inflow and Infiltration (I&I) detection.
What support does OSSCAD provide for the implementation and use of the Optical Radar System (ORS)?
