Abstract

Sewer systems that convey both sanitary sewage and stormwater through a single pipe are referred to as combined sewer systems. This system diverts all flows exceeding the design capacity to the receiving watercourses in heavy rain events. Therefore, environmental regulations limit the use of this system and separate sewer systems are currently used in all new developments. However, the UK, most other European, and other countries usually have narrow streets occupied by a complex network of infrastructure services. About 70% of sewer systems in the UK and Europe are combined systems. Finding a space in which to place another two sets of pipes (in a separate sewer system) is therefore challenging. This research is regarding a design which is capable of overcoming this challenge by a modified system for the sewer networks. The system includes a proposed new design for the manhole shape, which will allow the storm flow and the foul flow to pass through the same manhole without mixing and allows using one trench to set two pipelines. This will bring economic advantages by decreasing construction cost by about 30% plus extra protection for the environment by separating sewage from stormwater, decrease footprint by 16% and construction time by 18%.
