How the type of water plays a role in green building

Green building can be identified as a sustainable practice. It’s a practice that helps to reduce the negative impact generated by construction or engineering firms when building, as well as preserve water for future generations. Plenty of businesses and individuals don’t realise how easy it is to conserve water if you implement the right systems and resources for your building venture and business operations.  

Green building for your business doesn’t necessarily mean that it will cost more. If you use the correct materials and implement them in environmentally friendly ways, it could reduce your overall spend entirely. The Leadership in Energy and Environmental Design (LEED) is a green building rating system developed by the United States Green Building Council (USGBC) and it identifies different water diversification methods by categorising them into the following groups: potable water, grey water, black water and process water. Each of these is used in different ways for the building process.

In upcoming years, water efficiency will become just as important as recycling construction waste and conserving energy when committing to a green building method. This sustainable practice demands water conservation as well as encourages building companies to make use of recycled and grey water in their operations. This will prevent water waste and encourage water treatment for potable use where possible.

Here are the four different types of water and what they’re used for:


Potable water

When it comes to green building, the LEED standard recommends that employees and builders do not take advantage of fresh potable water for any form of building or cleaning. This water is only for human consumption, and therefore should not be used for any cleaning purposes. Landscaping and building projects should make use of recycled or grey water initiatives to conserve water and reserve fresh water for necessary reasons. This will not only help you to save water and contribute to green building, but it will decrease the water bill significantly just by using water which would simply be wasted otherwise.


Grey water

Building companies are advised to make use of grey water in their building efforts as well as for their portable toilets which workers to make use of. Grey water can be identified as untreated but not contaminated water. Should businesses prefer to have this water treated for cleaning and landscaping purposes, grey water can be treated through a water purifier bought from water specialists. From the building of companies to the indoor plumbing needs thereafter, grey water can be used in place of municipal water. This way, the freshwater demand will be less and only used for potable reasons.



If businesses are prepared to go the extra mile and invest in a water treatment solution to treat any non-potable water, the benefits on the environment will be worthwhile. Blackwater should not come into contact with any human for obvious reasons. In short, blackwater contains liquid and solid waste. It’s contaminated water that is extremely dangerous to be around, therefore building water should be treated before it’s used for any reason. The latest technologies have helped to recycle blackwater into water that can be used for building and cleaning purposes. If treated according to LEED standards, there will be minimal pollutants or contamination in water, therefore it can be used for landscaping purposes. For the most part, black water will turn into grey water after being treated. But, still, it has not been recommended that you consume this water. Over time, technologies will enable this benefit.


Process water

This type of water is used in cooling towers, chillers and boilers. Naturally, this water is not regulated for water saving purposes, but if you make use of rainwater or greywater instead, you will be able to reduce the pressure and amount of water used for plant purposes. Cooling towers use excessive amounts of water, so it’s critical to try and tap into alternative sources for water supply. If you make use of recycled water, you will need to treat the water. The reason for this is because of the buildup of minerals in the pipes. Try to remove as many chemicals and pollutants as possible as a clogged pipe affects its performance and leads to costly maintenance services. Once water from cooling towers is discharged, be sure to use it for other reasons, for example, the water can be reused for irrigation purposes.


Final words

With the right water treatment solutions, you will be able to contribute to a sustainable environment. Water conservation is essential for business success and the future of our environment. It’s easy to adapt, all you need to do is understand the green building practices and the different types of water components.
