Sprinkler Irrigation System – How it Works?

A sprinkler system is a passive fire protection system, consisting of either a fixed water supply or a combined water-supply/fire sprinkler system, supplying sufficient flowrate and pressure to a fixed water supply piping system, on which active fire sprinklers are installed. It is usually located in the ground basement, roof top or on the outside walls of a building. There are basically two types of systems: the forced-air and the water-supply systems. With the former, water is supplied by means of gravity, while the latter supplies water through the use of pressurized gas or liquid solutions.

Sprinkler irrigation systems require a large labour force, in terms of both men and materials. This is because the installation is labour intensive. In the case of forced-air sprinkler systems, it is not so. The installation process can be undertaken by any person who has basic knowledge of plumbing. The installation process for water-supply systems can be undertaken by any person who has basic knowledge of high-pressure pump and associated systems.

Sprinkler head is the portion of the sprinkler system that dispenses water, either from above or below the ground. Two types of heads are available for the system; the above ground type and the ground pump unit. The typical sprinkler irrigation system has an upper or a lower line, which connects the upper mainline with the bottom of the underground structure.

If you have read any book on sprinkler installation, you would have learnt about the principle of hydrostatic pressure, which helps to determine how much water is dispensed to the sprinkler heads as well as the rate at which water is recovered. The larger the area that you are spraying, the greater the hydrostatic pressure. The actual size of the area that you want to wet will determine the pressure. The more areas you are going to wet the smaller the individual tested circle. Thus, the larger the area the larger the individual tested circle.

The area in square footage is called the crop. The actual size of the crop is denoted by the figure that indicates the perimeter. In case you are targeting a small patch of land with a high moisture requirement, you can just use the figure as the maximum area. The figure is called the wetting pattern.

The actual size of the area to be watered will determine the pattern. For example, if you are going to water a 100 square foot section then you need to water a much larger section than if you are going to water a much smaller area. The actual calculation is this: the wetting ratio or the hydrostatic pressure will be multiplied by the area to be watered multiplied by the atmospheric pressure. Thus, the actual pressure at which the water jet does not break up is called the atmospheric pressure. If you are dealing with very small areas, then you just use the atmospheric pressure. On the other hand, if you are dealing with a much larger area, then you multiply the area by the actual hydrostatic pressure.


The next thing to consider is whether you are using the lower Mainline or the higher laterals. The laterals have two sections, namely the upstream and the downstream. The upstream starts at the top and flows downwards. The laterals, on the other hand, flows in a spiral fashion. The difference in these two is that the laterals take water from below and let it flow upwards; whereas, the Mainline takes water from above and allows it to pass through laterals before delivering it to the ground.

Thus, when it comes to irrigation, the Sprinkler system san antonio irrigation system is highly effective. The system ensures less watering need and thus saves you from trouble watering delicate crops in times of heavy rain. These days, almost every farmer is using Sprinkler irrigation as they are quite efficient and save you money on water as well as the environment.
