The cost of a drip irrigation system in Zambia per acre is a topic of interest for many, especially those venturing into the agricultural sector. Drip irrigation is a highly efficient process that allows water and nutrients to flow directly into the plants’ root zone in the required quantity at the required time. This ensures that the plant gets the exact amount of water and nutrients it requires for proper growth. In this article, we will delve into the cost of installing a drip irrigation system per acre in Zambia, the factors affecting the cost, and the advantages and disadvantages of the system.

Cost of Drip Irrigation System in Zambia Per Acre

In the realm of modern agriculture, drip irrigation has emerged as a game-changer, particularly in regions like Zambia where water conservation is crucial. This method of irrigation allows water and nutrients to flow directly into the plants’ root zone in the required quantity and at the required time. This ensures that the plants receive the exact amount of water and nutrients they require for proper growth.

Cost Estimation

Estimating the cost of a drip irrigation system per acre in Zambia can be quite tricky due to the influence of various factors. Generally, the cost of one acre ranges between KW500,000 and KW1.5 million. One of the core factors affecting the cost is the location. For instance, the prices of drip irrigation in states like Lusaka or Ogun tend to be more expensive than in a few other states. Another significant factor is the contractor handling the process. If you employ a standard professional, you should expect to spend more than when employing a starter. Also, if you are looking to import the materials you will be using, there will be a slight difference in the eventual cost.

Factors Affecting Cost Description
Location Prices vary from place to place
Contractor Professional contractors charge more than starters
Material Source Imported materials may cost more

Advantages of Drip Irrigation System

There are numerous advantages associated with drip irrigation. Some of these include:

  1. Prevention of Soil Erosion: The steady and gentle drip process reduces the amount of runoff, which helps prevent erosion.
  2. Water Conservation: Drip irrigation targets the roots of the plants, where the water and nutrients are largely required, reducing waste.
  3. Reduced Need for Drainage and Leveling: Unlike regular irrigation systems, drip irrigation reduces the need for in-depth drainage since water is channeled only to the required parts.
  4. Weed Reduction: Since water only flows to required parts and there is reduced waste, it significantly helps reduce weeds.
  5. Prevention of Diseases: Drip irrigation puts water at the base of the plants rather than on the leaves, helping prevent mildew and minimizing diseases that can grow and spread on wet leaves.

Disadvantages of Drip Irrigation System

Despite its advantages, drip irrigation also has some drawbacks:

  • Clogging: There is a high tendency for the small holes along the drip lines to get clogged easily, especially when the water contains iron.
  • Requires Constant Maintenance: The drip irrigation process requires constant maintenance and a need to constantly check the drip line.

Components of a Drip Irrigation System

A typical drip irrigation system consists of the following components:

  • Pump unit
  • Control head
  • Mainlines and sub-mainlines
  • Lateral lines
  • Emitters or drippers

The system may also include additional features, such as reservoir tanks, filters, and fertigation devices.

Installation of a Drip Irrigation System

The installation of a drip irrigation system involves several steps:

  1. Lay Out Irrigation Grid: Plan out where the hoses will go and mark all plants that will need to be watered. Each plant should have its own emitter or drip.
  2. Assemble the Hoses: Install a backflow preventer valve to the outdoor faucet and attach a hose adapter to fit the diameter of the system’s main line.
  3. Install Tees for Branch Lines: Place a tee in the line for each branch line and secure with band clamps.
  4. Install Emitters and Feeder Lines: Punch holes in the line for all drip irrigation emitters with an emitter tool. Place emitters in the desired locations next to plants.


In conclusion, a number of variables, including location, the contractor, and the source of materials, affect how much a drip irrigation system costs per acre in Zambia. While the system has numerous advantages, it also has a few drawbacks that need to be considered. However, with proper maintenance and careful planning, a drip irrigation system can be a highly efficient and cost-effective solution for agricultural practices in Zambia.
