Study Notes
Components of Micro Irrigation System (MIS)
- Micro-irrigation systems are often described as branching systems.
- Branches are named such as main, submain, and lateral.
- It is important to choose the correct size of pipes for each branch to match the flow rate.
- Important components include a pump and power unit, a backflow prevention device, a filter, a water distribution system, and devices for controlling water volume and pressure.
- A direct connection is possible if the water source is from a city/municipal/rural water supply.
Pumps and power unit
- Pump size is determined by the amount of water required, desired pressure, and its location in relation to the distribution network.
- Electric power units or internal combustion engine driven pumps are both suitable.
- Electric powered pumps can provide consistent water pressure.
Micro-Irrigation System Components
- Electric power units are preferred for micro-irrigation systems because they are easy to automate
- Micro-irrigation systems use filters to remove sand and suspended particles, but not dissolved minerals, bacteria, or algae
- Common filter types are screens, disk filters, and sand filters.
- Water distribution system consists of pipes and tubes ranging in size between 12 mm to 150 mm in diameter
- Water from the main pump is transported to the field's edge then to submains and laterals for ultimate delivery to emitters
- Control head unit components:
- Pump/Overhead Tank: Ensures sufficient system pressure
- Fertilizer Applicator: Used to introduce fertilizer into the pressurized irrigation system
- Filters: Prevent blockages and clogs for efficient and trouble-free operation
- Types of filters:
- Gravel or Media Filter: Consists of fine gravel or quartz sand (1.5-4 mm in diameter) placed within a cylindrical tank to remove algae and other organic matter.
