2.3.2 Grid Iron System:
This system is also known as reticulated system and is most convenient for towns having rectangular layout of roads. This system is an improvement over dead end system. As seen in the figure 5 above all the dead ends are interconnected and water circulates freely throughout the system. Main line is laid along the main road. Sub mains are taken in both the directions along other minor roads and streets. From these sub mains branches are taken out and are inter connected as shown in figure. This system removes all the disadvantages of dead end system (McGee, 1994).
