A swimming pool is a tank or container filled with water that people can swim in. They can range from small portable play toys for kids to major landscape features that cost hundreds of thousands of dollars. Budget, lot size, and local laws will factor into what type of pool a home owner decides to install on their property. Swimming pools can be a great source of entertainment and exercise for the whole family, but they also present a risk of death due to drowning, especially for young children. As a result, many communities require homeowners to have fencing that restricts access and/or use of their pools. Drowning is a leading cause of death for young children, so parents should always supervise their children when they are in and around a pool.
Swimming pools are generally used for recreation and athletic competition. In addition to regular swimming, the sport of swimming includes racing and other events that are regulated by the Federation Internationale de la Natation (FINA). The Olympic Games include 18 swimming events. Competition pools are generally indoors and heated to enable year-round swimming and meet the standards of FINA.
The most common types of pools are geometric, lap and diving pools. A geometric pool has even lines and is usually rectangular in shape. A lap pool is designed for training and health and fitness, so it is often long and narrow. Diving pools are deep, ranging from 3 to 6 m in depth. They may include platforms or a diving tower.
