Human knowledge has developed over the centuries, and we now have a much firmer understanding of chemicals and how they react with each other. Humans had no qualms about drinking dirty water or food and did not connect it with any illnesses they may have gotten. Contamination just was not something that those early humans understood. Now that we know better, we are fully aware of the dangers that germs and bacteria represent. Every day, we do things to help prevent the spread of those germs and keep ourselves from getting sick. This is important when it comes to pool maintenance. We use chlorine to sanitize our pool water and keep it pure. Here are some reasons why we need chlorine in our pools.
The water in your pool can come into contact with contaminants in many ways. They are often presented to the water through humans, but they can also come from nature. Humans sweat, wear cosmetics and emit bodily fluids. These can all end up in pool water. Dust, debris, and bacteria can be swept into the water on the wind, can fall from trees, or can be left by rodents or birds who end up in the water. While an indoor pool might be able to protect from the natural sources of contamination, it cannot protect against the human source.
Keeping to a regular chlorination schedule is one of the most important steps in any pool maintenance schedule. It will help ensure that the water is kept at its most hygienic level at all times. What happens when chlorine is added to the water is that it breaks down into chemical compounds. These compounds are mostly hypochlorous acid and hypochlorite ions. To make sure that the chlorine is at its most effective, the pH level of the pool needs to be at the right level. That means keeping your pool water at a pH of 7 to 8.4. 7.4 is, in fact, the perfect level.
As mentioned, human scientific knowledge has vastly improved when it comes to chemical reactions. When chlorine takes the form of the hypochlorous acid or hypochlorite ions, it attacks the lipids that are present in bacteria. It will also kill enzymes in the bacteria. This, in effect, kills the bacteria and makes it safe. Since pools have so many microorganisms and bacteria in the water, chlorine is a great way to get the water safe for us humans to use.
The Town has the following ordinance in place to ensure health and safety standards are in place with regards to pools and their maintenance:
Sec. 3.07.069 Health and safety standards; clarity of water
(a) The water in all swimming pools within the town, public or private, shall be of sufficient clarity such that the bottom of the swimming pool is visible to the naked eye. In order to help achieve this objective, each swimming pool shall have a minimum fee residual chlorine of one (1) part per million.
(b) In addition, no swimming pool water shall have an acid reaction to a standard pH test.
(c) All pools shall be treated, altered or maintained so as to prevent the development of unsanitary conditions.
(d) Pools under construction or which are no longer being operated shall be maintained in a manner so as to prevent the development of unsanitary conditions, potential injury or possible drowning.
(e) Wastewater from a swimming pool that is subject to the provisions of this article shall be discharged into a sanitary sewer. There shall be no direct physical connection between the sewer system and any drain from the swimming pool or circulation system.
(2006 Code, ch. 3, sec. 15.04(K). See end of this division for full history for this division.)
The Town of Trophy Club wants residents and their guests to enjoy swimming in the pool and cooling off on hot days. It is necessary to add chlorine to make sure that everyone can enjoy the water safely. However, it is important to make sure that the chlorine is handled and used properly at all times.
