What is Onsite Water Reuse?

Onsite water reuse systems collect, treat and reuse a building’s wastewater locally instead of sending used water to a centralized municipal system for treatment. Wastewater (also known as greywater or blackwater depending on its source) is the term for used water that is sent down drains when we run our taps, flush our toilets, or wash our clothes. Rainwater or stormwater are also a forms of wastewater that can be collected and treated for reuse in our systems. Learn more about the different types of wastewater.

The collected wastewater is stored onsite then filtered and cleaned using a multi-step treatment process that include membrane filtration, UV treatment and chlorine disinfection to remove impurities and contaminants. Once treated, recycled water, or reclaimed water, can be reused in the property for a variety of non-potable (non-drinking) purposes, like in irrigation, toilet and urinal flushing, clothes washing, ornamental water features like fountains, and in cooling tower HVAC systems. 

Onsite water reuse systems create a decentralized, circular approach where a building or community can become self-sufficient in its water use and management. This helps real estate owners reduce operational costs while saving water and creating a more sustainable and resilient building.

Reduce building costs, achieve green certifications, and meet regulatory requirements

Our sustainable solutions can reduce water demand by up to 95% and save owners thousands on utility fees annually.

Population growth, aging infrastructure, and water scarcity are putting pressure on municipal utilities and increasing water and sewer rates. These high costs are felt most acutely by large building owners and developers. With a focus on space efficiency, Epic Cleantec’s sustainable water reuse solutions reduce water demand by capturing, treating, and recycling wastewater onsite for non-potable uses such as toilet flushing, clothes washing, cooling towers, and irrigation. The savings can total hundreds of thousands of dollars annually.

Greywater or blackwater reuse: which is best?

For projects deciding between greywater or blackwater systems, there are many factors to consider.

When deciding which system is best for your project, there are several key differences in what each system type offers that can affect the overall decision-making process. Installation costs, water and carbon savings, MEP impact, system footprint, and energy efficiency are just some of the factors at play. Learn more about the difference between the two system types to help you choose which is right for your next project.
