What is the Meaning & Definition of pool

A sink or swimming pool is an aquatic area artificially created by man to recreate the natural aquatic environments, but to do so in the best conditions, to ensure that there attend comfort, safety and health. The pools can be constructed in many different ways, in different shapes and sizes and in addition can also be performed with different objectives.
The pools are one of the most interesting elements to man in terms of recreation and fun. These are surfaces built on holes made in the ground and which are filled with water (after being covered with suitable material). When it comes to constructed pools for sports, we must then talk about usually square or square pools that are properly marked and divided into lifts to avoid collisions or accidents among those who make swimming. In this sense, the larger pool size is having any Olympic pool, which reaches 50 meters in length.
However, the pools can be also constructed with mere recreational purposes, in which case we must talk about pools of various shapes and sizes: cuagrangulares, square, round, oval, irregular shapes, etc. These pools do not have in the majority of cases signage since they are not only intended to allow people to cool off and play without limits of space. The recreational pools are characteristic of large resorts and hotels. Many of them (especially those with the highest level), are equipped with eccentric pools that occupy great spaces, are completely irregular in shape and are also surrounded by parks, Palm trees and other equally artificial elements. Finally, many of them also are connected with jacuzzis, pools for children, waterfalls and other water attractions.
So a pool is properly enabled, the water should contain the proper proportion of chlorine (ingredient that serves to keep the water clear and free of bacteria), as well as be periodically cleaned and renovated all of the water. It is also important that the material with which it is built is soft and not extremely rough to avoid creating injury in people's skin.
