Since it is a design criteria for road drainage and sewer systems, the infiltration performance of permeable concrete block pavement (CBP) is of important significance during the service life of a road construction. Due to the entrainment of mineral and organic fines into the pores of porous concrete blocks or into the aggregates used in joints or openings, the irreversible reduction of water p...

Extreme climate events are becoming more intense in Melbourne in recent years. This increasing intensity of excessive rainfall has an adverse effect on the sewer network by causing sewage overflow hazards. Extreme rainfall events increase flow into the sewer system, both directly (inflow) and through infiltration into sewer. As a result of this Rainfall Derived Infiltration and Inflow (RDII), S...

A practical algorithm for 3-D interpretation of images taken in a sewer by a robot-inspector is presented. Modern sewers made of concrete present regular circular structures originating at the pipe ends as well as at the joints of the pipe sections. These pipe ends and joints provide regular marks on the sewer images and can be used for their 3-D interpretation. The key idea of the paper is to ...

Asset management in hydraulic infrastructures aims for the long-term sustainability of water distribution and wastewater networks. Strategic maintenance planning has thus been deeply analyzed literature individual sewer pipes. However, utilities do not plan perform replacement activities on elements, but rather coherent aggregations neighboring We have developed a decision support system (DSS) ...

A water-sampling device to monitor the quality of water periodically and temporarily flowing out of concrete tubes, sewers or channels is described. It inexpensively and easily enables a qualitative characterization of contamination via these point-source entry routes. The water sampler can be reverse engineered with different sizes and materials, once installed needs no maintenance, passively ...
