basseinid

Basseinid are man-made water-filled basins designed for swimming, recreation, exercise, or training. They vary in size and design and can be located indoors or outdoors. Common construction materials include reinforced concrete, fiberglass, or vinyl liners, while some natural pools rely on biological filtration and plant beds rather than conventional chemical sanitizers.

Typical configurations include in-ground pools embedded in a landscape, above-ground pools on a frame, private residential pools, public or community pools, lap pools for training, and indoor pools in sports facilities. Natural swimming ponds, which emphasize ecological balance, are also built in some climates.

Pools use circulation and filtration systems to remove debris and regulate water quality. Filtration options include sand, cartridge, and diatomaceous earth filters, paired with pumps. Water treatment commonly relies on sanitizers such as chlorine or bromine; alternatives include ozone or UV. Maintaining proper pH, alkalinity, and calcium hardness is essential.

Public pools are subject to safety requirements, including barriers, lifeguards in designated areas, and non-slip surfaces. Routine maintenance involves skimming, vacuuming, brushing walls, and testing chemical levels. Seasonal closure or winterization is common in temperate climates.

Estimates of cost and energy use vary with size and features. Efficiency measures such as pool covers, energy-efficient pumps, and solar heating reduce operating expenses and water loss through evaporation. The modern swimming pool landscape developed in the late 19th and early 20th centuries, expanding globally thereafter.
