Water use in buildings will depend on the plumbing-fixture type – how the building is used and the type of equipment installed. For instance, the water consumption of kitchens and cafeterias in commercial buildings is higher compared to those in a residential setting.
However, while these may have higher water consumption, they are not the majority users of water. Instead, restroom plumbing fixtures, like showers, urinals, lavatories, and water closets consume more than half of the total water usage in offices and other commercial buildings.
Since restroom fixtures account for most water use, the best chances for improving efficiency can be found there. The great news is, the availability for high-efficiency plumbing fixtures is increasing.
What You Should Do:
To make the facility more water-efficient, you must understand first how water is used. Installing sub-meters and monitoring the different areas of the building will allow you to know more about water usage. This will also help you and building engineers determine problems within the water systems of the building. This way, you can plan and implement projects to reduce water usage effectively.
- Replace older and high-flow flush valves and water closets with new models that meet or exceed recent Uniform Plumbing Code (UPC) and International Plumbing Code (IPC) specifications.
- Consider changing the current plumbing fixtures with high-performing fixtures that meet or exceed recent UPC and IPC specifications.
- Use dual-flush valves on your water closets.
