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:
a) Avoiding sewer impacts on groundwater quality by infiltration of soil water into sewers and
exfiltration of sewage into soil water, occurring rather as a cycle depending on the flow conditions
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
area coverage in the available financial and human resources to create and sustain the system.
This chapter presents the following:
Part – 1 Estimation of Design Flows Part – 2 Types and Hydraulics of Sewers Part – 3 Design of Sewer Networks
Part – 4 Types and Construction of Manholes
Part – 5 Laying, Jointing and Construction of Sewers
