Abstract

The urbanized area Biskra-East of the, is currently experiencing significant problems with the disposal of wastewater with a unitary system. These problems have a significant impact on the proper functioning of the sanitation system. Identified through an accurate diagnosis, where the main shortcomings in the malfunction of the system and infrastructure were identified, such as cracks caused by the interactions between the collectors and the Earth, as well as non- compliance with standards. In this context, two solutions were considered to solve these problems. The first consists in the use of rehabilitation techniques adapted to the degree of perceived defect. The second option, considered in extreme cases, will offer a complete refurbishment of the wastewater and stormwater drainage system
