In SE Asia most resorts and residential developments have pools. More and more individual properties also have swimming pools of some description. In recent years huge strides have been made in regard to making pools more environmentally friendly.
Recent reports suggest that chlorine levels in pools are often two hundred to four hundred times higher than what is considered safe for the environment. Findings suggest that swimming in chlorinated pools also puts young children at increased risk of developing asthma.
There are now alternatives to using chlorine in pools and non-chemically based cleaning products. A traditional chlorinated pool can be converted to a salt water pool. While a salt water pool will still contain chlorine the difference is that the salt system makes the chlorine naturally, eliminating the need to constantly buy and add chemicals. While the initial cost is higher the long term savings and benefits are huge.
Pure water swimming pool systems are also becoming more popular. Often water is re-circulated onto small rocks and then through sand box filters. Bacteria and algae are killed by an ultra violet sterilization system. Water can be passed through specialist magnets and the minerals are agitated in the water to help achieve a satisfactory PH balance.
At the extreme end, natural swimming pools offer the most environmentally friendly implementation and upkeep. They use gravel, stone and clay in place of concrete or fibre glass and aquatic plants instead of harmful chemicals and mechanic filtering systems.
Traditionally people have relied upon chemicals to maintain their pools and spas, however now more and more products are on the market which are not only more green but also a healthier option for human beings. Plants are one option for naturally breaking down harmful bacteria but so are products including natural enzymes and organic materials. Ask your local swimming pool supplier for suggestions.
Water conservation is another environmental concern, and large amounts of water evaporate naturally from pools all over the world every day, only to be replaced by a rapidly dwindling supply. Pool covers will reduce evaporation and conserve water and should be used whenever the pool is not in use or owners are away from the property.
Adding a timer on your pool pump and running it only periodically will help conserve electricity and right now new solar powered pool pumps are just starting to come onto the market.
If you are considering installing a new pool there are many environmental concerns to take into account, including materials used in the construction, amount of chlorination used, type of filtration system put in and cleaning agents. Trying to keep toxic chemicals to a minimum is the smart choice for obvious reasons, but conserving water and electricity should also be taken into account. After all, an environmentally safe pool is also safe for children and leaves hair in pristine condition rather than with that horrible green tinge.
