Introduction to Swimming Pools

Constructed from materials like concrete, natural stone, metal, plastic, composite, or fiberglass, pools can be custom-built or standardized, with the Olympic-size swimming pool being the largest. In addition to recreational and exercise purposes, specialized pools are designed for diving, water sports, therapy, lifeguard training, and even astronaut training. Pool water is typically treated with chlorine or salt and can be heated or unheated. The history of swimming pools dates back to the 3rd millennium BC, with the “Great Bath” at Mohenjo-Daro in modern-day Pakistan being the earliest known example. Since then, swimming pools have become an integral part of human culture and continue to serve various purposes in today’s society.

Types of Swimming Pools

Swimming pools can be broadly categorized into two types: in-ground and above-ground pools. In-ground pools are constructed by excavating the ground and installing a basin made of materials such as concrete, natural stone, metal, plastic, composite, or fiberglass. These pools can be custom-built to various sizes and shapes, including the standardized Olympic-size swimming pool. Above-ground pools, on the other hand, are freestanding structures or integrated into larger buildings, such as ocean-liners and cruise ships. They are typically made of materials like steel, aluminum, or resin, and are available in various sizes and shapes. Both in-ground and above-ground pools can be further classified based on their intended use, such as public pools, private pools, hotel pools, educational facility pools, hot tubs and spas, and specialized pools for diving, water sports, and therapy. Each type of pool has its own unique construction techniques, materials, and maintenance requirements, catering to the specific needs of its users (Cody, 2017; Swimming Pool, 2023).
