CHAPTER 3: DESIGN AND CONSTRUCTION OF SEWERS

3.1

GENERAL

The major roles of a sewer system can be listed as follows: - Improvement in the environment by removing the sewage as it originates - Preventing inundation of low lying areas that may be otherwise caused by not providing sewers - Prevention of vector propagation by sewage stagnations - Avoiding cross connections with freshwater sources by seepage

In addition, there is a strong emphasis on:

in leaky sewers, and b) Moving away from the mind-set that a sewer system shall necessarily be an underground sewer right in the middle of the road with costly construction, upkeep and remediation and making the objective realizable if necessary in an incremental sewerage commensurate with optimizing the
