The letter /NC/ Eight lanes with a minimum width of 2.5 meters (8 feet 212 inches) from the center line to the center line of the lane dividers, plus about 0.45 meters (1 foot 6 inches) of free water outside lanes 1 and 8. For the National Championships, Program Operations may waive this criterion. If your pool does not meet these requirements, you cannot use it for competitive purposes.
The recommended minimum size for a competition pool is 25 meters by 75 meters (82 feet by 244 feet). Larger pools can be used for long-course (50-meter) events or smaller ones for short-course (25-meter) events.
The depth of a pool should be such that it will not cause injury if someone falls in. This means that the maximum depth of a pool should be 16 inches at the deepest point. The average household pool is about 9 feet deep and 18 inches wide across its widest point. The height of a pool should be such that anyone can swim fully dressed in it. This means that the maximum height of a pool should be 4 feet 10 inches or higher. Most household pools are about 3 feet high and 12 inches wide.
The volume of a pool is calculated by multiplying its length by its width by its height. For example, a pool that is 50 feet long by 20 feet wide by 4 feet high has a volume of 250 square feet. Pools larger than 24 feet by 36 feet require some form of cover.
A minimum lane width of 7 feet is required by most swimming rule books. In the prime competition course, a typical collegiate swimming pool 50 meters long by 25 yards wide will have a lane width of more than 9 feet. (75 feet divided by 8 = 9 feet 1 and 13/16 inch plus two 11 and 7/8 inch buffer lanes.) For practice or trial use, smaller pools may be suitable.
The starting line for each lane is called the block wall. It is usually made of wood or plastic and ranges in height from 2 to 4 inches. The block walls should be smooth with no steps or ledges that could cause you to stumble as you reach for the surface. They should also be free of any objects that might cut into your skin (such as a metal ring) or cause you to hit hard surfaces (such as a wooden board). The block walls should be well lit so that you can see where you are going before you dive in.
After the block wall comes another wall: the back wall. This is the wall behind you as you swim. It is usually made of glass or some other transparent material. You need this in order to determine how close you are to the end of the pool when you swim freestyle or backstroke. If you run out of space to the side, you will have to turn yourself around which means stopping what you are doing and starting again. This is called "breaking" or "splashing" and it is important not to do it too often otherwise you will lose speed.
The eight lanes should be 2 meters wide, with 0.2 meters of free water beyond the end lanes, according to FINA requirements. Ten lanes are necessary for major competitions like as the Olympics and World Championships. A 12-lane pool can be used for trials and other large events.
The standard Olympic swimming pool is 50 meters long by 25 meters wide. The larger 100-meter-long pool is used for backstroke and breaststroke events while the smaller 50-meter pool is preferred for individual medleys and other shorter races. At both the 2004 and 2008 Games, some racing took place in 25-meter pools because facilities were not yet ready or capable of holding longer events.
The current world record holder in the 100-meter freestyle is Michael Phelps at one minute and 49.04 seconds. The record holder in the 200-meter individual medley is Ryan Lochte with two minutes and 57.14 seconds. The 4x100-meter freestyle relay world record is 3:19.44 set by Australia in 2003.
The women's 880-yard freestyle final at the 2012 London Olympics was won in a time of 1:54.06, with Japan's Akiko Suzuki taking gold.

50 metres (164 feet). Breadth of 25 meters (84 feet) The number of lanes varies between 8 and 10. 2.5 meter lane width (8.2 feet) Minimum depth: 2 meters (6.6 feet) Temperatures vary between 25 and 28 degrees Celsius (77 to 82 degrees Fahrenheit). Water quality affects how long you can swim in it. Boiling water will kill most bacteria and viruses.
The pool is filled with water that is almost at the same temperature as your body. This is called thermal immersion. It helps swimmers avoid getting cold or hot during exercise.
When the pool is full, there are about 1 million litres (250,000 gallons) of water inside. That's enough to cover the pool floor to a height of about 1.5 meters (5 feet).
The pool is divided into three separate sections for different types of swimming events. Each section has its own set of rules regarding heaters, lights, and other equipment that may be used inside the pool.
Olympic pools are built for maximum safety. They have layers of protection to prevent any danger from electrical wires, lockers, or any other possible source of danger. Even though they are made to protect people from drowning, anyone who enters the pool without knowing the requirements should assume that they could suffer from a fatal accident.
A typical community four-lane competition pool may be 12 yards by 25 yards with an average depth of 1.7 yards... for a total of 103,000 gallons (390,000 liters). That's about 31 million ml (11 million imp cups), which is approximately 2.5 times the volume of water in the Nile River when it is at its lowest point.
There are 4 billion people on earth today and it is estimated that they will need more water than we have now. Water is needed to grow food, to produce energy, and to maintain our homes. It is important that we find ways to use water more efficiently so that everyone can enjoy its benefits while protecting our environment against overuse and abuse.
The amount of water used by humans is increasing because of economic growth and the increased demand of agriculture and industry. At the same time, many areas are becoming increasingly dry due to climate change. This means that there is less water available for other uses like drinking and farming.
In conclusion, one way to reduce your consumption of water is to switch off the tap when you brush your teeth or wash yourself. This will help save water for future use. Of course, you should also try not to use so much soap - think before you wash! - and avoid washing your car in full public view if you can help it.
