Water management has become a top priority for businesses and industries across the USA, especially as sustainability and cost-efficiency grow more vital. One term that’s gaining traction in commercial water storage solutions is the cistern. While this term might seem old-fashioned to some, cisterns have been reimagined for modern use and now play a crucial role in efficient water conservation and usage strategies.
In this article, we’ll explore what a cistern is, its relevance today, the benefits it offers, industrial use cases, and tips for maintaining cistern tanks effectively. Whether you’re involved in manufacturing, agriculture, commercial construction, or hospitality, understanding the value of cisterns can help streamline your water management strategy.
Understanding What a Cistern Is
A cistern is a watertight tank or container designed to collect and store water for later use. Historically used in homes and farms to gather rainwater, today’s cisterns have evolved into sophisticated water storage systems used in both small- and large-scale commercial applications.
Cisterns are typically made from durable materials like concrete, fiberglass, polyethylene, or steel and can be installed above ground or underground depending on the use case and space availability. Modern systems often include filtration units, pumps, sensors, and smart monitoring technologies that ensure the water remains clean and readily accessible when needed.
How a Cistern Works
A cistern collects water from sources like rainwater runoff, wells, municipal supply lines, or treated greywater systems. Once collected, the water is stored until needed. For commercial and industrial use, cistern systems are often integrated with buildings or production lines, supplying water for:
- Non-potable uses like irrigation, toilet flushing, and cooling systems.
- Emergency reserves for fire suppression.
- Reducing dependence on municipal supply and lowering utility costs.
Gravity or electric pumps are used to distribute the stored water throughout the facility. In more advanced systems, filtration and purification mechanisms can make stored water suitable for broader usage.
Benefits of Using a Cistern for Commercial and Industrial Applications

1. Cost Savings on Water Bills
One of the most attractive benefits of installing a cistern is the reduction in water bills. Businesses that consume large volumes of water, such as food processing plants or commercial laundry services, can realize significant savings by utilizing rainwater or recycled water stored in cisterns for non-drinking purposes.
2. Sustainability and Environmental Impact
Using a cistern supports sustainable water practices by reducing reliance on municipal systems and groundwater. Collecting and storing rainwater also helps reduce stormwater runoff, which can cause erosion and waterway pollution. For companies aiming to improve their environmental, social, and governance (ESG) scores, implementing water cistern systems can be an excellent strategy.
3. Emergency Preparedness
For industries where downtime can lead to substantial losses—such as data centers or manufacturing plants—cisterns can provide a backup water supply during outages or droughts. Many fire safety codes also require a dedicated water storage system, which a cistern can easily fulfill.
4. Regulatory Compliance
Many states and municipalities encourage or mandate water reuse systems for new construction projects, especially in areas prone to drought. Installing a cistern may help businesses comply with building regulations and obtain LEED (Leadership in Energy and Environmental Design) certification.
5. Versatile Installation Options
Cisterns can be customized in size and material to suit different business needs. Underground cisterns save space and offer thermal insulation, while above-ground models are easier to install and maintain. Businesses can even connect multiple cisterns in series to expand capacity as needed.
Common Commercial Uses of Water Cisterns
1. Agriculture and Horticulture
Farms and greenhouses use cisterns to irrigate crops, often collecting rainwater to meet irrigation demands during dry seasons. Since this water doesn’t need to meet drinking standards, cistern systems are a practical and cost-effective solution.
2. Construction and Mining
Construction sites often require large volumes of water for dust control, concrete mixing, and equipment cleaning. Cisterns provide on-site water storage that can be quickly refilled and reused. Similarly, mining operations use cisterns to store process water or support dust suppression systems.
3. Hospitality Industry
Hotels, resorts, and event venues use water cisterns to maintain landscaped areas, fill pools or fountains, and supply greywater for restrooms. This reduces strain on municipal supply and demonstrates environmental stewardship to guests.
4. Manufacturing and Industrial Processing
Water is essential in various manufacturing processes, from cooling machinery to washing components. Storing water in cisterns provides a buffer that helps regulate flow, manage quality, and reduce peak demand charges from utilities.
5. Institutional Use: Schools, Hospitals, and Government Buildings
Large institutions can benefit from water cisterns by lowering water bills and ensuring consistent water supply for sanitation and cooling systems. Many of these facilities also use cisterns as a backup water reserve for fire suppression.
Types of Cisterns and Their Materials
Choosing the right type of cistern depends on your storage requirements, location, and application. Here are the most common types:
1. Above-Ground Cisterns
Ideal for areas with space availability and where freezing isn’t a major concern. These are easy to inspect and maintain and come in a variety of shapes and capacities.
2. Underground Cisterns
These offer space-saving advantages and are protected from extreme weather. They are ideal for high-capacity storage needs, especially when aesthetics and space limitations are concerns.
3. Modular Cisterns
Used for scalability and flexibility, modular systems can be expanded or reconfigured as your needs change.
4. Mobile Cistern Tanks
These are transportable tanks mounted on trailers or trucks, useful for temporary construction sites or emergency water delivery.
