Would you want to install an irrigation system in your home? Read the excerpt below to understand the various considerations you should make when choosing an irrigation system. 

Irrigation Permits

You do not need a permit to use harvested rainwater from your tank or pond for irrigation purposes. However, you need a licence from the water department if you intend to draw water from a natural water source such as a river or lake. If you live in a strata development that shares the same water source, check if there are restrictions using the shared resource for irrigation purposes. 

Choosing an Irrigation System 

Below are the various types of irrigation systems to choose from; 

  • Surface irrigation systems use gravity. Typically, you connect a hose and water plants in your compound. They are an ideal choice for people with a low budget or those that have small gardens.
  • Drip irrigation can be used for domestic or commercial use. The system comprises a set of pipes with small perforations that release water at the roots.
  • Sprinkler systems. They can come with microjets, pop-up sprinklers, or spray systems. For commercial use, go for a system that uses rotors. They can spray water to a broader area.
  • Centre pivot irrigation is ideal for commercial use in flat areas. They consist of multiple sprinklers connected on a mobile platform.

Water Pressure and Flow

The effectiveness of the irrigation system is heavily reliant on water pressure and flow. For instance, a sprinkler may be dysfunctional if the water has very low pressure. On the other hand, drip irrigation systems do not require high pressure. It's an effective way to save water. Use thinner pipes to increase the water pressure in the system. Very thin pipes will reduce the water flow; hence reducing the effectiveness of the system. A professional can help you decide which pipes are suitable for your farm.

You also need to consider the water source. For example, you need a pump if you intend to draw water from a well or river downstream. When buying a water pump, check its flow rate, max head (the height that the equipment can pump water) and the water pressure.

Conduct some research to determine the durability of various irrigation products on the market. Preferably, work with suppliers that provide guarantees and after-sales services such as free installation and transport. Finally, consider regular inspections, maintenance and repairs to keep the system in tip-top condition.

When choosing an irrigation system, determine the need for permits, choose a suitable system, check the water pressure and flow and go for durable products.
