There can be a lot of infiltration/inflow [I/I] (i.e. stormwater, 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 individual drainage well, weak pipe joints, or 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.
