There can be a lot of infiltration/inflow [I/I] (i.e. rainwater, surface/ground water) detected in the sanitary sewer collection system. The more I/I detected, the worse the network. These I/I sources can be determined by using AquaDuoscope® measuring method. With AquaDuoscope® you can get online information on the technical condition of the sewer network and excellent efficiency for your maintenance investments.
What´s being inspected? The pipeline area can be a large part of the network or a single catchment area. The inspection is usually conducted in two parts: first a few crossover pipeline measurements to determine the I/I situation on the area, then a detailed inspection goes through the worst I/I producing pipelines and determines their I/I sources.
How to analyze? Infiltration/inflow can enter the sewer network through, e.g., the leaking seam of an individual drainage well, weak pipe joints, or a broken pipelines. In some areas, the rainwater coming from the roofs and drain pipes of buildings is directed to the sanitary sewer collection system. With the AquaDuoscope® inspections we can find and determine the sources of I/I in the sanitary sewer collection system.
We measure and analyze the flow rate and composition of the wastewater. This information helps us detect the amount of I/I and then determine the sources of it
What do you gain from the inspections? The inspection results clearly reveal the infiltration/inflow in the sanitary sewer collection system – and the need of renovations. The information generated by the AquaDuoscope®inspections makes it easy to prioritize the renovations to the most critical pipelines.
Using the AquaDuoscope® measuring method we have launched on the market, we are able to determinate the amount of and the sorces of the I/I in the sanitary sewer collection system.
When infiltration/inflow enters the sanitary sewer collection system, certain values (e.g. pH, ORP, temperature) change and it is reflected in the analysis results. Integration of the machine learning, the I/I content (%) of the wastewater sample can be determined and the results stored in the ever-growing AquaDuoscope® database.
The information generated by the AquaDuoscope® inspections makes it easy to plan and target the necessary renovations to the most critical pipelines. Systematic inspection and subsequent renovations will radically decrease infiltration/inflow from the sanitary sewer collection system.
The AquaDuoscope® measuring method is now available as a Software as a Service. Municipality Water Supply and Public Works Personnel will be provided with the AquaDuoscope® training, sample taking insturctions,operating license and the necessary measuring tools so that they are able to perform I/I inspections in their own sanitary sewer collection system.
