---------------------------------------------------------------------***--------------------------------------------------------------------2.1 Discharge: Abstract: Irrigation is an essential part of farming. Maharashtra government try to develop best irrigation network for irrigation of all region. But with the help of Gravity fed Canal network it is not possible to provide irrigation at remote area. In now days Lift Irrigation Scheme ( LIS) plays an vital role for irrigation of this remote area. In LIS water has lifted from source i.e. Dam, lake or river to the delivery chamber with the help of pumps and distributed to all command area with canal network. The success of LIS is mainly depend on accurate planning, designing and selection of pumping equipment's. For designing of any LIS , design and selection of pump , R.L. of bottom of sump, R.L. of M.D.D.L. in the sump , P.O.L, Static Head , Diameter of rising main etc. all these parameters should be considered . In this paper we will get clear idea about design of Lift Irrigation Scheme (LIS) and clear idea about what care should be take while designing of LIS.

i) Maximum discharge required discharge required 2.2 Various Control Levels: i) Normal Water Level Draw Down Level )

iv) High Flood Level

v) Discharge Point level

vi) Sump Floor level

vii) Motor floor level

viii) Valve floor level

ii ) Rising

1) Following tabel gives the selection of pumps according to the use of application and according to various duties:

Lift Irrigation scheme is used for supply of water to remote area where gravity fed canal network is not work. In LIS pumping stations are used to lift the water to appropriate height with required pressure. In the pumping stations Pump plays a vital role. Pump is 'heart' of all system as it converts mechanical energy to hydraulic energy. For proper working of LIS with high efficiency utmost care must be taken while planning, selecting & designing of pumping equipments & accessories. The following points must be considered to develop a new LIS.[1]

Table 1.1: Selection of Pump for LIS

i) Selection of Pumps. ii ) Intake Design iii) Layout of the pump house. iv) Selection of valves v) Selection of motors vi) Selection of Starters vii) Selection of capacitors viii) Selection of Control Panel ix) Selection of HT cables x) Selection of auxiliary transformers xi) Delivery pipe & Rising main.
