Irrigation And Water Supply System
Some Important Criterias :
- Climatic Conditions
- Soil Characteristics
- Plant Materials
- Available Watering Time
- Property Size And Shape
- Location Of Buildings, Trees And Other Fixed Objects
- Elevation Changes
- Economic Consideration
Types Of Irrigation
- Sprinkler System
- Quick Coupler System
- Drip Irrigation System
Application & Design
- Golf Courses
- Interior Planting
- Athletic Fields
- Gardens And Landscapes
Sprinkler Irrigation System
- Polyvinyl chloride (P.V.C.) Pipes
- Polyethylene (P.E.) Pipes
- Copper pipes
- Galvanized steel pipes
- Asbestos cement pipe
- Cast iron pipe
- Concrete pipe
Compared with Sprinkler Irrigation
The energy used by an irrigation system depends on both the total amount of water pumped and the pressure needed to distribute it. Micro-irrigation systems operate at lower pressures than sprinkler systems, so micro- systems use less energy to move the same amount of water.
Further, micro- systems are more efficient users of water than are other irrigation methods, since they apply water to plants only, not to the entire soil surface. Thus the total amount of water pumped in a micro- system can be as little as, half that of a sprinkler system, resulting in further direct energy savings.
Types of Drippers
Pressure Compensating Drippers allow for pressure differences within the system while giving a uniform flow rate at each dripper,
Non-Pressure Compensating Drippers work well on small to medium size systems,
Adjustable Drippers are non-pressure compensating, and can be adjusted for different flow rates, and Inline Drippers are made to work with small diameter poly tubing.
Motoroll is an aluminum pipe (lateral) mounted on large wheels.
The Motoroll irrigates in place and it is moved from position to position between irrigation runs.
The supply line may be located along one edge or in the center of the field.
Irrican Irrigation Systems
. When an irrigation run is finished, the operator simply turns off the mainline valve and disconnects the flexible hose.The drain valves automatically drain the pipe due to the reduced pressure.
Water Supply Systems
Types Of Water Tanks
Dead End System
In This System A Central Is Laid Which Takes Its Supply From The Service Reservoir And To Which Is Connected A Number Of Sub mains Or Branches In Both Directions, And Which Have No Interconnection Except At The Beginning And Thus Making Dead Ends
Grid Iron System
Pipes are laid in the shape of network resembling a grid iron, connected at intervals at street intersections and there are no ends
The supply main is laid around the periphery of the area of the district and branches are connected crosswise to the main connection
Centrally laid separate reservoir are provided at each district or zone and the supply pipes are laid radially.
