Pool Basics


Swimming pools come in many different shapes and sizes, but nearly all of them, from the backyard personal pool to the water park wave pool, work in the same basic way. The concept behind these is the use of a combination of filtration and chemical treatment to continually clean a large volume of water.

A typical swimming pool needs seven major components:

  • A basin / pool shell
  • A motorized pool pump
  • A water filter (normally sand filter)
  • A chemical feeder (manual or automatic chemical dosing system)
  • Drains / Skimmers / Overflow gutter / Main drains
  • Return inlets
  • PVC plastic plumbing (pipes and fittings) connecting all of these elements
The basic idea behind a swimming pool is to pump water in a continual cycle, from the pool through the filtering and chemical treatment systems and back to the pool again. In this way, the pumping system keeps the water in the pool relatively free of dirt, debris and bacteria. There are also various different types of heaters (electrical heaters and heat pumps) that can be added to the filtration system to maintain the water at a certain temperature.
