How to Reduce Water Usage in Commercial Real Estate
Every gallon of water used in a commercial property carries a financial and environmental cost. From restroom fixtures to landscaped grounds to cooling systems, buildings can consume substantial amounts of water simply through everyday operations.
For commercial real estate leaders, cutting that demand can deliver benefits beyond a smaller utility bill. Smarter water management can advance sustainability targets while helping properties remain resilient as water supplies face greater pressure.
Why Water Conservation Matters in Commercial Real Estate
Growing populations and competition among households, businesses and agriculture place pressure on local water supplies. Conservation helps protect freshwater resources while reducing the energy needed to treat, pump and distribute water. In the U.S., major droughts have also fueled greater interest in reducing water stress.
Expanding water supplies can require costly infrastructure and face political hurdles. Conservation often provides a more affordable and feasible alternative, giving commercial properties another reason to improve efficiency. These efforts can also support green building certifications and corporate sustainability commitments, making everyday building operations a logical place to start.
1. Measure Water Consumption and Identify Waste
Water demand can vary widely depending on a property’s purpose and tenant operations. For example, electronics manufacturing and cloud computing can have substantial water footprints that place added pressure on nearby communities and ecosystems. Executives can identify problem areas by reviewing utility bills, conducting water audits and comparing consumption across similar properties.
Submeters and smart water meters provide deeper insight by showing where and when unusually high consumption occurs. This information can reveal which buildings, systems or operations offer the greatest opportunities for improvement. With a reliable baseline, developers can set realistic reduction goals and measure progress over time.
2. Specify Water-Efficient Fixtures and Equipment
Water efficiency should begin during property design and renovation, rather than becoming an afterthought once a building is operational. Executives should direct development teams to establish portfoliowide standards for water-efficient fixtures, like low-flow faucets and waterless urinals, focusing on the long-term ROI of these capital investments. Choosing these features early can make conservation a routine part of building performance.
Prioritizing upgrades requires weighing installation costs against expected reductions in water and utility expenses. However, efficient equipment still requires consistent care. Regular inspections and maintenance can catch leaking or malfunctioning fixtures before they waste water and erode projected savings.
3. Expand Water Reuse Across the Property
Water conservation can extend beyond efficient fixtures when properties capture and reuse water before it enters wastewater systems. Rainwater and properly treated greywater can support nonpotable uses, such as toilet flushing, irrigation and cooling tower makeup, where local regulations permit.
Effective stormwater management can also strengthen property resilience as worsening floods and severe hurricane seasons increase potential losses for insurers and insureds. For example, Hurricane Ian increased insurance rates by about 5.3% in the commercial market during the third quarter of 2022. Investing in enhanced stormwater systems can be a crucial step in mitigating these rising costs and protecting property value.
Executives should evaluate reuse infrastructure during early development, since retrofitting storage and treatment systems can become more complex and costly. Water quality requirements also vary according to the intended use. Reviewing local codes and treatment needs can help developers create safe, practical water reuse systems.
4. Reduce Outdoor Water Consumption
Landscaping can account for significant water demand, especially at commercial properties in hot or dry climates. Native and drought-tolerant plants can reduce supplemental irrigation needs once established. Property teams should also inspect irrigation systems regularly for leaks, overspray and damaged components that waste water.
Rainwater harvesting offers another way to reduce dependence on potable water where local regulations permit. Captured rainwater can support landscape irrigation and, with appropriate treatment, provide makeup water for cooling towers. These applications can lower freshwater consumption, reduce water costs and shrink a property’s overall water footprint.
5. Improve Cooling and Building System Efficiency
Cooling towers and other mechanical systems can consume substantial amounts of water in certain commercial properties. Teams can reduce waste by monitoring system performance and adjusting how often cooling towers drain and refill, which helps conserve water while protecting equipment. Properties with data centers can also consider liquid-cooling designs that minimize water consumption in water-constrained areas.
Routine inspections of pipes, valves and mechanical equipment can uncover leaks and inefficient operation. Properties may also capture HVAC condensate for replacement water in cooling towers or for irrigation. Executives should coordinate these measures with energy goals, maintenance needs and indoor environmental requirements to avoid improving water efficiency at the expense of overall building performance.
Make Water Efficiency Part of Ongoing Property Management
Lasting water reductions require ongoing management, including tracking water-use intensity and reviewing performance against established targets. Property managers can train maintenance teams to identify leaks and excessive consumption while engaging tenants through conservation guidance and shared sustainability goals.
By combining efficient design, continuous monitoring and water reuse, commercial real estate leaders can reduce costs while advancing long-term sustainability.
