floating materials. The water thus entered in the inlet chamber flows to the outlet chambt:r through a It:ading channt:1. This is fixed with a "V" notch to measure the dischargt: into the outkt chamber. The supply <strong>of</strong> water to the ayacut will be through pipes <strong>of</strong> lesser diameter as per the design. The inlet ends <strong>of</strong> the pipes are covered with welded mesh to prevent entry <strong>of</strong> debris. The pipelines are so aligned to form a network <strong>of</strong> pipes so as to command the entire ayacut by gravity !l(n\,. The pipes and specials used under this system are <strong>of</strong> PVC type varying in diameter from 200 lTllTl to 90 mm depending on the water requirement at each delivery point. Necessary pressure release arrangements are being made to rekase the pressure created in the pipeline at suitabk points. called. risers. h\ ,) t: pe~ ,)1' Jell\ cry 1")II1IS are there in the ': stelll. \'JZ .• hydrants and alpha. wlh:e1 \aln: chamhers. ilydrants is a pipe connection taken from the end <strong>of</strong> thl' hUrled pipe ahove ground I.:\cl using GI pipe <strong>of</strong> I m. with 50 mm. wheel valve outlets. These are encased in a concrete shell called hydrant having a diametn <strong>of</strong> 60 Clll. And 1.2 Ill. hcil!ht with cover and locking arrangements to regulate the opening valves. Two 50 mm. diameter GI pipe outlets from the 50 mm. wheel valves protrude outside the shell above the ground level so as to connect deliverv hoses havinl! a length <strong>of</strong> 45 meter long. The hydrants are . , located at about 90 m. apart. The discharge <strong>of</strong> water from each outlet is 2.5 litersl sel:ond making the total discharge frolll (lnL' hydr:Jnt as live litersl second. These hydrants ;,Jre located at pLl.:es in the ayacut where there is sufiicient pressure head <strong>of</strong> water to command the an:a with two hoses (45 m. long each). For the efficient functioning <strong>of</strong> the system. the pressure head should not be less than 1.2 • 119
meters. The end <strong>of</strong> the buried pipeline is connected to alpha! wheel valve <strong>of</strong> size ISO mm or ~OO mm. This system is encased in a chamber covering a slab and with locking arrangements. This is applicable at places where the pipe line ends to feed wet land where the pressure head is low (see, Chart 4.1, for understanding the functioning <strong>of</strong> the MCS). The MCS is implemented in farmers' plots not by acquiring the plot. but with the legal consent <strong>of</strong> the farmers or the public under the provisions <strong>of</strong> the CADA act. The \1CS schemes taken up in the KIP are sent to CADA for appro"'al and later it is published in the gazette for the information <strong>of</strong> the farmers! public before the scheme IS taken up. The responsibility <strong>of</strong> implementation <strong>of</strong> ~1CS in the KIP rests with the Super-intending Engineer, \ICS Circk .. \ddor. l:ndcr this circle. there is one 0 & M division and four MCS \\orks dl\lsl(1n,. six Assistant Directors (Agri.) and 5~ Agriculture Officers. 4.2.5 Farmers' participation in irrigation management and \Vater Users' Associations Farmers' participation in irrigation management IS expected to be ensured through the formation <strong>of</strong> Water User's Associations (WUAs). On completion <strong>of</strong> the MCS bv the Irrigation Department. which will be handed over to the Water Users' ASSOCiations Three tier committees arc formed to coordinate water distribution activities; and they an:: Water User's Association. Canal Committee, ., he brrm:rs cDming under the ayaclIt Df an MCS scheme will be the members <strong>of</strong> the WI lAs. The Association will have an elected President. 120
