PLANNING AND DESIGN OF PIPE DISTRIBUTION NETWORK (PDN).
The Main Objective Of This Topic Is To Highlighting The Use Of Pipe Distribution Network (PDN) Instead Of Canal Distribution Network (CDN) To Increase The Overall Project Efficiency Of Irrigation Project And Thereby Reducing The Stresses Due To Water Scarcity. For Achieving Maximum Benefits From PDN, Planning, Designing, And Construction Of PDN Should Be Done Carefully. In This Topic Guideline For Planning, Designing And Installment Requirements Of PDN System For Irrigation Are Provided. It Is Recommended That PDN System Could Be Economical And Feasible Over Conventional CDN Certain Extent And This System Is So Flexible That It Can Be Implemented As A New Scheme Or Used To Convert The Existing CDN.

- 9. PDN system saves water over conventional canal distribution network system. The maximum benefits of the PDN system can be utilized if planning and design of PDN system should be done carefully. When land cost is comparatively high then adoption of PDN system is more suitable. CONCLUSION 12/9/2019 9
