Contrary to what many people would assume, a pool isn't just a shaped reservoir of water wherein to take refreshing dips on hot days. The principal behind their design and construction incorporates useful knowledge, soaked up from the wider fields of hydrology, architecture, biology to the everyday experience of matters water. Below are some approaches that contractors use in perfecting pools and pool service.

Structure

The fundamental requirement of a pool is that it should hold water reliably. Losses due to seepage, evaporation and overspills are considered and planned against in the pool design. Likewise, measures are put in place to avoid inadvertent introduction of ground water from adjacent earth.  Surface run-off water is also denied entry. Pool contractors use special mortar and building techniques to ensure that your water isn't contaminated by untreated, outside water. Contractors ensure that pool bottoms are sloped with one end much higher than the other. This allows people whose swimming skills aren't good enough to limit their activities to safe depths, while experienced swimmers use the deeper end for skilful underwater manoeuvres and diving.

Circulation

If left to stand stagnant, water quickly will go stale and cloudy, sometimes giving off unpleasant odours. This is a health hazard to swimmers as it may cause waterborne diseases and skin irritations. Pool contractors install elaborate plumbing systems that are constantly refresh pool water. These systems include aeration and filter mechanisms that ensure your water remains odourless, clear and safe from disease causing organisms.

Temperature control

The water in pools meant for recreational purposes needs to be maintained at a comfortable temperature. Whether you want take a dip in the noon sun or in moonlight, the experience must be agreeable at all times. To accomplish temperature control, contractors may erect a stylish sun shade over an outdoor pool. They also use active measures, such as powered heating and cooling systems, connected to the pool.

Water treatment

You don't see algae, slime and plant matter growing in your pool; this is because the water has been chemically treated to suppress their growth. Pool contractors use an automated chlorine injection system that introduces measured quantities of chlorine into the circulation system. Besides killing off plant matter, chlorine treatment kills bacteria, fungus and protozoa that carry spread skin infections. Treated water doesn't give off unpleasant odours, since bacterial action is what produces the smelly gases.

Pool contractors operate using a deep reserve of proficiency to ensure excellence in utility and safety of every pool project.
