The applicability of advanced technology in sewer systems

The need for using advanced technologies in existing and new constructed sewer system projects is essential to improve the system and minimize the probable malfunctions. For several reasons, the frequency and severity of malfunctions in sewer systems are observed to be much more in developing countries than in the developed ones. The implementation of advanced technologies in sewer systems has clear advantages, but in some circumstances, accompanied with some difficulties that limits its use. In this research, the feasibility of several types of advanced technologies relevant to sewer systems was investigated. Among those technologies, the hydraulic efficiency of the implementation of non-circular pipes in sewer systems or through lining existing systems was investigated. Also, computer program packages that are used for the design of gravity flow sewer systems have been investigated in order to evaluate their applicability. Different other advanced technologies were also presented and investigated. The availability and applicability of those advanced technologies in developing countries were investigated.
