Irrigation is the supplementation or replacement of rainwater with another source of water. The main reason behind irrigation systems is that your plants and lawns can be maintained with the minimum amount of water required.
Water is a brittle natural resource, and we have to incorporate many methods to preserve it and not over-use it. An irrigation system helps to conserve water while saving your money, time, preventing weed growth and increasing the growth rate of your lawns, crops, plants and flowers.
TYPES OF IRRIGATION SYSTEMS
Ditch Irrigation
Ditch Irrigation is a traditional method, where ditches are dug out, and the seedlings are planted in rows. These plants are watered by placing furrows or canals in between the rows of plants. The water from the main ditch to the canals is moved with the help of siphon tubes. This system of irrigation was very popular in olden days, but most have been replaced with the modern irrigation supplies in Perth.
Drip Irrigation
Drip Irrigation is one of the most water-efficient methods of irrigation. In this method, the water drops in a dripping motion right near the root zone of a plant. If this system is installed properly, you can gradually reduce the loss of water through evaporation and runoff.
Terraced Irrigation
Terraced Irrigation is a very labour-intensive method where the land is cut into steps and supported by retaining walls. In this method, the flat areas are used for planting, and the idea of using this type of irrigation supplies in Perth is that the water flows down each step, while watering each plot. This process allows the steep land to be used for planting crops.
Sprinkler System
Sprinkler System is based on overhead sprinklers, guns or sprays, installed on permanent risers. You can also have this irrigation system buried underground and the sprinklers rise when water pressure rises. This is a popular irrigation system used on golf courses and parks.
Centre Pivot Irrigation
It is a type of overhead irrigation system. Aluminium or steel pipes are joined together, supported by trusses and mounted on wheeled towers. The sprinklers are placed on the length of the tower, and they move in a circular motion.
Rotary Systems
Rotary System is one of the irrigation methods, which suits best for larger areas, since the sprinklers can reach distances of up to 100 feet. The term “Rotary” is an indication of the mechanically driven sprinklers moving in a circular motion, therefore reaching greater distances. This system helps to water a larger area with less amount of water over a longer period.
Sub-irrigation
In this sub-irrigation system, water is distributed across the land by raising the water table through a system of ditches, gates, canals and pumping stations. This type of irrigation is most effective in high water table areas.
