Irrigation Pumps

Water is the most crucial input for agricultural production since it is necessary for plant growth. Irrigation is the replenishment of soil water storage in the root zone of plants using means other than natural precipitation. Agriculture uses 50-70% of the water consumed in Australia per annum, and irrigation uses 90% of that.

Dowdens Pumping & Water Treatment with over 45 years of experience in irrigation stand ready to help you with any application from drip and sprinkler to centre pivot and linear irrigation solutions.

Irrigation Applications

With drought, which is all too prevalent in Australia, relying on rain is a gamble. The natural application of water to the soil by direct rainfall is known as rain-fed farming. Irrigation is the process of applying water to the soil artificially using tubes, pumps, and sprays.

There are a variety of irrigation techniques in which water is evenly distributed throughout the entire area. Irrigation water can originate from various sources, including groundwater, springs and wells, surface water, rivers, lakes, reservoirs, and even treated wastewater or desalinated water.

Common Irrigation Applications

Drip IrrigationDrip Irrigation

Drip irrigation is an excellent water irrigation method that can have a significant impact on the land. By slowly drawing water either onto the soil surface or directly on the root zone of the crops, you can supply sufficient water as well as fertiliser to prevent over-watering and conserve water resources. Drip irrigation networks can either sit above ground or be submerged underground — offering a considerable benefit to crops, lawns and other vegetation by minimising evaporation and encouraging your greenery to absorb more water and nutrients. 

Sprinker IrrigationSprinkler irrigation

There are three main methods of sprinkler irrigation. Each offers its advantages and disadvantages depending on where you need to supply water. Some sprinkler systems include:

  • Pop-up sprinklers

Pop-up sprinklers, as the name implies, pop out of the ground and retract again when not in use. They allow you to supply water to large land areas and require irrigation pumps to maintain water pressure and a constant flow to ensure enough coverage to water a lawn, golf course or bowling green.

  • Mini sprinklers and micro-jets

More suitable for smaller outdoor areas such as shrubbery, perennials and orchards, mini sprinklers and micro-jets allow you to water targeted areas with little wastage and water run-off. Whilst they work well in smaller spaces, they can be damaged easily and require active use for longer periods to supply adequate water.

  • Overhead sprinklers

Typically confined to nurseries and orchards, overhead sprinklers quickly supply water to larger areas with the downside of increased water wastage. Overhead sprinklers require adequate irrigation water pumps to maintain high water pressure — otherwise, you risk your irrigation pump burning out.

Pivot IrrigationCentre pivot and linear irrigation

Large pastures and cropping areas require advanced pumping and irrigation. This can be achieved through centre pivot and linear irrigation systems, which allow for the highly efficient water supply necessary to service large areas. 

The centre pivot releases water from the centre resulting in water being released in circular motions, and linear irrigation involves water being discharged in a straight back and forth movement.

Flood IrrigationControlled flood irrigation

As the name implies, controlled flood irrigation requires land to be flooded to quickly supply large pastures of grain and fodder crops with water. Flood fed irrigation offers a fast and efficient water supply to secure and manage crops devoted to food supply channels.
