Intrusion Detection Technology for Rainy Weather in Sewage

Water & Soil Water Quality Improvement / Water Management Technology Water Supply / Sewerage

Although RII into sewer systems is one of the factors increasing the operational cost of public wastewater business, countermeasures against the infiltration have not been taken sufficiently due to its survey costs and the limited number of employees in wastewater operators. Therefore, we developed…
