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> largn diamd
in terms <strong>of</strong> underground pipeline system, water loss in the conveyance will be minimum. This system works under gravity flow. A minimum slope <strong>of</strong> three per cent is necessary for the effective working <strong>of</strong> the system. In places where the required slope is available the spout is connected to the hydrant in case <strong>of</strong> dry lands and Alpha / wheel valves in case <strong>of</strong> wet lands through underground PVC pipes. In places where the slope <strong>of</strong> three per cent is not possible open field boothies are constructt:J for distribution <strong>of</strong> \\ater. The success <strong>of</strong> the MCS depends on the coordinated efforts <strong>of</strong> the three agencies. viz .. the Irrigation Department. the Agriculture Department and the Water Users' Associations (WUAs). While the responsibility <strong>of</strong> supplying water from the head works up to the spout level through the canals and pipe system rests with the organisation and management (0 & M) division <strong>of</strong> the Irrigation Department. the :\griculture Ikpartment initiates the registration <strong>of</strong> WUAs for each spout and advice farmers to evolve a suitable cropping pattern so as to achieve maximum production per unit water delivered. Components <strong>of</strong> the l\1CS The major components <strong>of</strong> the MCS are: a) spout; b) pipeline system; and c) delivery points. The spout is constructed on the bank <strong>of</strong> the main canal! branch canal/ Jistributory from where water is let into the system. It consists <strong>of</strong> an inlet chamber control valve leading channel, measuring device and an outlet channel. These arc covered at top with slab anJ locking arrangements. The water from the canal is let in the inlet chamber through pipes <strong>of</strong> required diameter with a control valve. The inlet end <strong>of</strong> the pipe is protecteJ with GI mesh to prevent the cotry <strong>of</strong> 118
