Inflow and infiltration detector

Our solution

Aquapriori’s AquaDuoscope® is an efficient, sample-based technique to detect inflow and infiltration (I&I) in sewer systems. It is a fingerprint method locating the places where I&I gets mixed with wastewater. Results of the sample analysis can be found in the content of I&I in the sewer pipeline. Stormwater, groundwater and domestic drainage systems connected to sewer mains can be located. We offer our solution as a SaaS model. Our customers’ own staff does the fieldwork. It is easily combined with other techniques to give our customers a wider range of I&I inspections and opportunities for international ventures.
