Swimming Pool

A swimming pool is an artificially  enclosed body of  water  intended  for  swimming or  water-based Recreation. There  are many standard  sizes; the largest &  deepest  is  the olympic size. A pool can be built either  above  or in  the ground,and  from  materials  such as metal,plastic  or concrete.

Pools  that  may be  used  by  many people  or  the   general public  are  called public. while pools exclusively  by  a  few people or in a  home  are  called private.  Many health clubs, fitness  centers  and private clubs have public pools mostly used for  exercise.Many  hotels  and  massage  parlors  have public pools  for  relaxation.  Hot tubs  and  spa  are pools  with hot  water  used  for  relaxation  or therapy  and  are for  diving, other  sports and training  for lifeguards.

Pools must  be sanitized to  prevent growth and spread of  bacteria, viruses, algae  and insect  larvae  that  can cause  disease. This is done  using filters  and  chemicals  disinfectants  such  as chlorine,  bromine  or mineral  sanitizers.  A pool cover  can  keep  debris  out of a pool  that  is not in  use.  In cold climates, pools must  be  closed in winter  to prevent  them and their pipes from cracking due  to ice.
