Tenders Are Invited For Irrigation Piping Construction Work - Construction Of Public Irrigation System Lukač

Irrigation Piping Construction Work - Construction Of Public Irrigation System Lukač. In The Area Covered By The Project, The Construction Of An Irrigation System Covering An Area Of ​​447 Ha Is Planned, Which Will Enable The Connection Of Users To The Public Irrigation System Lukač In The Area Of ​​The Virovitica-Podravine County (Vpž), I.E. In The Area Of ​​The Lukač Municipality. Sn Lukač Consists Of The Following Facilities: • Coastal Fortification Around The Entrance Building In The Bed Of The Drava River; • Intake Of Water From The Drava River; • Construction Of The Pumping Station With Accompanying Facilities; • A Network Of Pressurized Distribution Pipelines With Sluice Gates And Irrigation Connections. The Necessary Amounts Of Water For Irrigation Are Provided By Direct Abstraction Of Water From The Drava River. Catchment Is Carried Out In The Growing Season (April-September), When The Largest Amounts Of Water Are Available. According To The Agronomic Basis (F. Bašić Et Al., October 2015), Monthly Irrigation Hydromodules Were Calculated According To Crops. Since The Rotation Of The Crop Rotation On The Agricultural Areas Is Planned, The Intake And Distribution Of Irrigation Water Must Be Dimensioned To The Required Quantities Of The Most Demanding Crops In The Crop Rotation (Tomatoes And Peppers). The Maximum Gross Operating Hydromodule In The Month Of July And The Associated Irrigated Area Give The Required Maximum System Capacity Of 290 L/S. The Captured Water From The Drava River Enters The Water Intake Shaft, Which Houses Low-Pressure Pumps With A Total Capacity Of 300 L/S And A Lifting Height Of 13 M. In Front Of The Water Intake Shaft, There Is An Entrance Building Integrated Into The Coastal Fortification. The Supply Pipeline With An Internal Diameter Of 500 Mm And A Length Of 33 M Connects The Water Intake Shaft And The Water Stilling Pool. The Pool For Calming The Water Has A Working Volume Of 140 M3, It Is Used For Settling Particles Of Suspended Sediment. Through A Sharp-Edged Spillway, The Water Flows From The Stilling Basin Into The Compensation Basin. The Compensation Pool Is Used To Accumulate Water, Which Ensures That The Suction Of The Pumps Is Submerged And The Operation Is Coordinated With The Pumps Located In The Water Intake Shaft. The Working Volume Of The Compensation Pool Is 250 M3. It Is Possible To Empty The Compensation Pool Into The Drava River Via The Sludge Outlet. The Pumping Station Is Placed Next To The Compensating Basin, So That The Suctions Of The Pumps Are Located In The Basin. The Total Capacity Of The Installed Pumps Is 300 L/S, And The Water Lifting Height Is 86 M. The Pumping Station Ensures A Minimum Working Pressure In The Distribution System Of 5.5 Bar. On The Western Side Of The Pumping Station, There Is A Substation With Transformers And Control Cabinets. A Macadam Access Road With A Width Of 6.5 M And A Total Length Of 770 M Will Be Arranged For The Access And Connection Of The Catchment Facilities With The Pumping Station To The Surrounding Road Network. Water To The End Users Will Be Distributed Through Pressure Pipelines With A Total Length Of 16,781 M. It Is Planned To Build 38 Control-Valve Shafts Along The Distribution System, And 218 Connecting Shafts Will Be Constructed For The Purpose Of Connecting Irrigation Equipment. The Intake Of Water And The Pumping Station Will Be Managed Through A Monitoring And Control System. Connection Of Irri
