Pool sanitation system: Enviroswim ES3

The Enviroswim ES-3 is a revolutionary pool sanitation system from Australia that eliminates the need to add chemicals to your pool to sanitize the water. This system removes the impurities from the pool using a combination of silver and copper electrodes, ionization and ultrasonics, leaving just pure, clean water.
Silver is an anti-bacterial agent, while Copper is an algaecide. Still, they don’t have any oxidizing properties, meaning there is nothing to break down the organic compounds that find their way into the water. Therefore the ES-3 uses a combination of both electronic oxidization and ultrasonics.

Many pool companies/builders are resistant to change and don’t like to recommend products they do not understand. Pool maintenance companies also make a lot of money from selling their customers’ chlorine-based products. Thus they aren’t keen on selling systems that will subsequently reduce their future income stream.

Here at Puglia Pools, we are more interested in bringing new, advanced systems to our customers so they can benefit from the advantages these systems provide. In Australia, these pool sanitation systems are top-rated. Additionally, the interest in freshwater pools is rapidly increasing as people want a more environmentally friendly and healthy lifestyle.

The advantages

The advantages of using the ES-3 include the following:

  • Kills bacteria that is resistant to chlorine
  • Vastly reduces chemical usage
  • Eliminates chemical smells
  • It removes the necessity for chlorine
  • Increases pump life
  • Allows you to swim in freshwater
  • It comes with a 2-year warranty


In 2009 the Enviroswim ES3 pool sanitation system was awarded the NSF 50 certification in the USA. Only products that pass stringent testing, including reliability, safety, microbiological efficacy, and pool surface stain resistance, receive this certification. The only consumables required for the ES3 are the electrodes that must be replaced every 18 to 24 months, depending on pool usage. The Enviroswim can be retrofitted to most existing pool systems with minimal adaptation.
People often worry that Copper stains pool surfaces. However, this only occurs if it is more than 1ppm, and the ES3 system operates at levels between 0.25 to 0.4ppm. The system comes with a simple-to-use test kit, so it is a simple job to ensure the correct levels are maintained. Suppose surface staining does occur due to pool negligence. In that case, removal is easy using citric acid, a commonly used stain remover.

The future of pool sanitation systems

The level of Copper and silver in the pool water is well below drinking water guidelines. In Queensland, the level produced by the ES3 is only 30% of the maximum recommended drinking water concentration. Furthermore, The backwash water from the pool is safe to discard into the gardens.
Swimming in freshwater is more enjoyable and better for your skin and swimming costumes. It is also better for your pool. Chlorine affects various parts of the pool system. Salt can cause damage to certain materials. Overall there is a growing list of health issues associated with bathing in chlorinated water. For this reason, several companies are now looking at new ways of sanitizing pool water.
