What Are the Best Techniques for Effective Water Reclamation in Commercial Real Estate Developments?

April 4, 2024

Water management in commercial real estate developments is an issue of critical importance. Striking a balance between sustainability and economic feasibility is paramount to the success of any development project. Water reclamation, the process of converting wastewater into water that can be reused for other purposes, is one such balance. Today, we aim to discuss the most effective techniques for water reclamation in commercial real estate developments.

Understanding the Importance of Water Reclamation

The need for water reclamation has never been more acute. As pressure mounts on our finite water resources, the role of water reclamation in conserving this precious commodity is becoming increasingly apparent.

Water reclamation is a critical component of a broader approach to water management that aims to reduce reliance on freshwater sources, mitigate environmental impact, and enhance water security in the face of climate change. It involves a range of processes including wastewater treatment, membrane filtration, and energy recovery.

If you were to Google "water reclamation processes", you would find a wealth of information from credible sources like Crossref and the Journal of Environmental Applications (JEA). These resources confirm the importance of embracing technologies that allow us to reuse water in a variety of applications, from landscape irrigation to cooling towers in buildings, thus saving energy and reducing environmental impact.

Wastewater Treatment Systems and Reuse

A significant part of water reclamation lies in the treatment of wastewater. Utilising efficient wastewater treatment systems is key to ensuring that water is safe and suitable for reuse.

One such system is the membrane bioreactor (MBR), a state-of-the-art technology that combines conventional activated sludge treatment with a membrane liquid-solid separation process. The MBR process offers several benefits over traditional systems, including high-quality effluent, compact design, and easy automation.

Moreover, the treated water can be directly reused for non-potable applications such as flushing toilets, irrigation, and washing cars. This not only conserves potable water but also reduces the amount of wastewater discharged into the environment.

Energy Recovery from Wastewater

While water reclamation often focuses on treating and reusing water, it can also involve the recovery of energy from wastewater. Energy recovery transforms the wastewater treatment process from a net energy consumer to a producer, contributing significantly to the greening of the environment.

In this regard, anaerobic digestion is a technique widely adopted in water reclamation plants for energy recovery. It involves the degradation of organic matter by bacteria in an oxygen-free environment, producing biogas that can be harnessed for heat and electricity generation.

Building Green Infrastructure for Water Reclamation

Green infrastructure plays a vital role in water reclamation. These systems, which include rain gardens, permeable pavements, and green roofs, mimic natural processes to manage stormwater and reduce reliance on traditional sewers and treatment plants.

Green infrastructure is not only an effective means of managing stormwater but also a way to create healthier, more sustainable urban environments. They improve air and water quality, reduce the heat island effect, and provide habitat for wildlife.

Implementing Water Reclamation Management Strategies

Finally, implementing effective water reclamation management strategies is crucial to maximising the benefits of these technologies.

These strategies can include comprehensive water audits to identify opportunities for reuse, the establishment of a cross-departmental water management team, and continuous monitoring and maintenance of water reclamation systems.

Such strategies ensure that water reclamation efforts are not just a one-off initiative but are integrated into the long-term operational and sustainability goals of the commercial real estate development.

To sum up, water reclamation in commercial real estate developments is a crucial undertaking that requires the right mix of technology, green infrastructure, and management strategies. Implementing these techniques can conserve water, reduce environmental impact, and contribute to the sustainability of our urban environments.

Leveraging Technology for Effective Water Reclamation

Digital technology has become an integral tool in water reclamation, providing innovative solutions to enhance efficiency and sustainability. Various technological platforms, such as Google Scholar, Crossref, and other academic databases, offer a wealth of research and data on water reclamation techniques.

Advanced techniques such as reverse osmosis and membrane filtration have proved to be highly effective in water treatment. Reverse osmosis, a process that involves forcing water through a semipermeable membrane to remove impurities, is particularly useful in producing clean water from wastewater. Given that the majority of the water in commercial real estate developments is used for non-drinking purposes, such as irrigation and cooling, the use of treated wastewater can significantly reduce the demand for potable water.

Moreover, digital technology can enable real-time monitoring and control of water systems, ensuring optimal water quality and efficient use of resources. For instance, smart meters can provide detailed data on water usage, identifying areas of wastage and opportunities for water reuse.

Water Reclamation in Practice: Case Study of San Francisco

San Francisco provides an excellent example of effective water reclamation in practice. The city has implemented a range of strategies to manage its water supply, including the extensive use of recycled water and rainwater harvesting.

San Francisco’s integrated water system treats and recycles wastewater, providing a sustainable source of water for irrigation, street cleaning, and other non-potable uses. The city has also implemented rainwater harvesting systems, capturing and storing rainwater for use during times of drought.

Moreover, San Francisco has adopted stringent water quality standards, ensuring that reclaimed water is safe for use. These standards involve rigorous testing and monitoring of water quality, safeguarding public health and the environment.


Water reclamation is an essential strategy for conserving water resources in commercial real estate developments. By leveraging advanced technologies such as reverse osmosis and membrane filtration, and adopting innovative approaches like rainwater harvesting and energy recovery from wastewater, we can ensure the sustainability of our water supply.

Moreover, effective water reclamation requires comprehensive management strategies. As demonstrated by San Francisco, these can include the use of recycled water, stringent water quality standards, and sophisticated monitoring systems.

In conclusion, water reclamation in commercial real estate developments is not just about treating and reusing wastewater. It’s about creating a holistic approach that integrates water management into the core of the development, maximising water efficiency, reducing environmental impact, and contributing to a sustainable future. With the right mix of technology, green infrastructure, and management strategies, commercial real estate developments can lead the way in water reclamation and contribute significantly to sustainable urban development.
