The idea of ​​recruitment is often used to refer to the process that is carried out with the aim of winning the sympathy or will of a person . A sect, in this sense, seeks to attract followers through lies and deception.
Recruitment also consists of adding adherents to a cause or entity. A sports club can develop a membership campaign with advertisements in the media and posters on public roads.

A non-governmental organization ( NGO ), in the same way, strives to attract volunteers to collaborate with its work. The media, for their part, invest money in attracting listeners, viewers or readers since this represents a greater consumption of their content and, therefore, a greater possibility of obtaining advertising income.
In some contexts, collecting water is known as catchment. There are several rainwater harvesting systems, which aim to collect and store said water and then put it to use. Cisterns are devices created for this purpose.
The structure built for the purpose of diverting a watercourse and taking advantage of its flow is called catchment or intake . With these structures it is possible to generate electricity or obtain drinking water, to name two possibilities.
The intake is a hydraulic structure (a concept that is also known as infrastructure or hydraulic work ); This means that the primary element of this construction is water. In this particular case, its objective is to carry out the diversion of part of the water that is available in a water course (such as a canal, a stream or a river), a lake or even the ocean.
Catchment is sometimes used in large rivers, although this carries very high costs. Once the water is diverted, it is taken to specific points where it will be used to supply drinking water systems , aquaculture, electricity production, irrigation or cooling of industrial facilities, among other diverse applications.
Regarding the process of construction of the catchments, it used to be done by gathering large amounts of stones and earth in the bed of a river, so that a portion of the water was forced to change course, in this case until it reached the diversion channel. . Some organizations continue to use this manufacturing model, although it is not very reliable and often requires extensive repairs or even total reconstruction every year, due to the action of the avenues.

When, instead, modern means are used to build a catchment, we can distinguish two fundamental parts:
* control gate, with its closing system;
* device for measuring water levels, which can be rules with a certain graduation, or equipment capable of constantly measuring the level and transmitting the data to the operations center, in which there may also be a system that allows operation to distance from the gate.
The catchments found in streams and rivers also usually have the following parts:
* a weir that serves to fix the section in which the water must flow, in order to prevent it from migrating;
* a canal with its own gates used to de-drain the water;
* a desander and a screen that prevent sedimentation in the solid transport channel, something that would make maintenance considerably more difficult.
