Each year, World Water Day is observed on March 22, and it provides an opportunity to highlight the importance of water conservation and management and to focus attention on the challenges and opportunities facing the global water community. In our industry, it’s an opportunity for us to look at the ways where we can maintain and improve water quality.

Maintaining water quality is an essential task in residential, commercial, and industrial buildings. Without it, there is an increased risk of waterborne diseases (like legionella). Legionella is a type of bacteria that can cause a severe form of pneumonia known as Legionnaires' disease. It is found naturally in freshwater environments, but it can also thrive in man-made water systems such as cooling towers, water heaters, hot tubs, and decorative fountains. Preventing legionella growth and transmission requires proper maintenance and disinfection of water systems. Here are four key steps to maintain water quality.

  1. Regular Maintenance
    Plumbing systems should be inspected regularly to ensure that there are no leaks, corrosion or other damage that might affect water quality. Additionally, flushing the plumbing system can help remove any buildup of sediments and bacteria. Flush infrequently used fixtures regularly.

  2. Monitor Water Temperature
    Drinking water in buildings must be kept at the right temperature and remain in motion to ensure proper hygiene. Water temperatures between 68°F and 122°F are considered safe for potable water. Anything outside of this range can promote the growth of bacteria and other harmful microorganisms. Using a Viega ProPress Automatic Recirculation Balancing Valve, water temperatures can be set and monitored automatically to ensure that water temperatures stay within the safe range.

  3. Regular Testing
    Water systems should be tested regularly. Tests can detect the presence of bacteria, lead, copper, and other contaminants. If any problems are detected, repairs should be made immediately.

  4. Install Water Filtration System
    A water filtration system can remove sediments, chlorine, lead, and other contaminants. In commercial or industrial buildings, building managers should select a filtration system that is appropriate for the building's water usage and that meets local and federal water quality standards.

Viega’s ProPress and PureFlow systems are designed for potable water applications. The ProPress Automatic Recirculation Balancing Valve keeps hot water recirculation systems balanced by adjusting flow with changes in temperature. The valve has a 1” BSP Connection end and can be used with Viega ProPress or Viega PureFlow for easy integration with copper or PEX. When used with other elements of a good system, like Viega double drop elbow fittings to reduce stagnation and eliminate dead legs, the Automatic Recirculation Balancing Valve improves circulation and reduces the likelihood of legionella contamination.
