• This is also called reticulation system

• The Sub-mains , Mains ,and branches are interconnected

Advantage:

• In case of repairs a very small portion of the distribution system area will be affected

• In case of fire , water is available from all directions

• As there are no dead ends , water circulates freely

• Loss of head is minimum at all points in the system

Disadvantage:

• Maintenance cost is very high

• As every zone requires a separate service reservoir , number of reservoirs required are more and hence the system becomes costly
