efficiency <strong>of</strong> 75 per cent has been taken for arnvmg at the irrigation
requirements at the canal head assuming 84 per cent conveyance efficiency (the
entire distribution system being lined) and field efficiency <strong>of</strong> 90 per cent. Since
the system is lined. an improved system <strong>of</strong> on-farm conveyance <strong>of</strong> water
distribution (through MCS) is effected and because <strong>of</strong> the undulating topography,
75 per cent efficiency is expected to be realised after a few year <strong>of</strong> operation <strong>of</strong>
the system in a scientific manner.
4.2.4 The Minor Conveyance System (:\lCS)
Kallada Irrigation Project is the first Project in India to adopt a distinct system
for water distribution called the Minor Conveyance System (MCS) in the ayacut
for water distribution. The MCS commands long strips <strong>of</strong> land containing side
slopes and \alley bottoms. Since the terrain <strong>of</strong> the Kallada command area is
undulating and where a majority <strong>of</strong> the farmers are small and marginal holders.
wata distribution system should be planned in such a way that the land acquired
for canal construction is minimum. Accordingly, under the MCS, underground
pipeline system with low pressure PVC pipes is designed and laid for 10 ha.
blocks within the KIP command. Farmers are able to tap water through flexible
plastic/ rubber hoses <strong>of</strong> 45 meters in length that are attached to hydrants located
at intervals <strong>of</strong> 90 meters in the pipe system. In areas where topography is plain
and the slope is less than 3 per cent, the conveyance system is a combination <strong>of</strong>
