To arrive at the cost of a drip irrigation system, you will need to consider several factors, including:
- Size of the area to be irrigated: The larger the area, the higher the cost.
- Micro Irrigation system design: The optimization of micro-irrigation system design is very important as it directly impacts the performance of the micro-irrigation system and total cost. The prime objectives of micro irrigation system design are:
a. Achieving higher water application and conveyance efficiency.
b. Optimizing initial as well as operation costs.
c. Long operational life and optimized performance.
d. Fulfilling the requirements of the crops.
- Type and quality of materials: Drip irrigation systems can be made from various materials with varying costs. For instance, PVC pipes are cheaper than polyethylene pipes.
- Type of emitters/drippers: There are different types of drippers, which vary in price. The most commonly used types include inline and online drippers.
- Filtration unit: Depending upon the type of water source and available water quality, you may need to select suitable filters to make the water fit for use through the micro irrigation system.
- Water Pressure & Discharge: Every micro irrigation system designed, has certain requirements of water flow and pressure to operate efficiently. You may need to install a suitable pump to fulfil these requirements, which adds to the cost.
- Labour cost: If you’re hiring someone to install the system, their labour cost will affect the overall cost.
- Maintenance cost: You’ll need to maintain the system regularly, which includes cleaning and replacing parts. This cost varies depending on the type of system installed.
Once you have considered these factors, you can estimate the cost of your drip irrigation system by adding up the costs of the materials, installation, labour, and maintenance.
