Water scarcity: the risk many hospitality projects underestimate
Water has become one of the most critical resources for any hospitality project in natural environments. Not only because of its increasing scarcity, but also because the way it is managed now defines operational viability, project resilience, and positioning in the eyes of an increasingly conscious traveler.
According to the World Sustainable Hospitality Alliance, a hotel can consume up to 1,500 liters of water per room per day, a figure that, in many destinations, exceeds average local household consumption by up to eight times. This pressure on water resources is no longer an isolated environmental issue: it is an operational and reputational risk that must be addressed from the design stage.
Water as a strategic project variable
In nature-based hospitality projects, water can no longer be understood solely as an operational input. Its availability and management directly influence project viability, resilience to environmental conditions, and the guest’s perception of value.
Water stress in many destinations, combined with municipal restrictions and rising supply costs, forces developers to rethink water from the design phase onward. Anticipating solutions that reduce dependence on external supply and optimize every stage of the water cycle helps protect the investment, ensure operational continuity, and build real sustainability, not a decorative one.b
Rainwater harvesting: designing to take advantage of every natural cycle
Rainwater harvesting enables the collection and storage of rainwater for non-potable uses such as irrigation, cleaning, and sanitary services. A well-designed system includes catchment and filtration surfaces, modular storage tanks, and controlled distribution according to demand.
According to sustainability-focused platform Edie, these systems can reduce mains water consumption by around 30%. In tropical climates or areas with regular rainfall, rainwater harvesting can cover up to 60% of the operational needs of a well-sized micro-resort.The difference lies not in installing a system, but in designing it as an integral part of the architecture, avoiding improvised solutions that often prove inefficient or costly to maintain.
Greywater reuse: closing the water cycle through design
In a hotel or micro-resort's water consumption, greywater is one of the greatest opportunities for optimization. This includes water from showers, sinks, and laundry, which can be treated with relatively simple systems and safely reused.
Greywater reuse allows it to be allocated to non-potable functions such as:
• Toilet flushing
• Irrigation of green areas
• Cleaning of outdoor spaces and common areas
When properly implemented, these systems can reduce potable water consumption by up to 40% while also enhancing environmental certifications and efficiency programs.
The key lies in timing. These systems must be designed as part of the architecture, not added afterward. Integrating them from the outset enables optimization of routing, proper sizing of tanks and filters, and avoidance of additional costs or invasive interventions later.
Here, modular architecture offers a clear advantage: by industrializing the process, it enables planning, manufacturing, and integration of reuse systems directly into modules, ensuring efficiency, aesthetics, and ease of maintenance.
Economic impact and brand positioning
Water-efficiency solutions deliver direct savings of 20%-50% in total water consumption, but their impact extends well beyond the numbers.
Today’s guest seeks coherence. Staying at a micro-resort that manages water responsibly reinforces perceptions of conscious luxury, authenticity, and a genuine commitment to the environment.
When these decisions are communicated transparently, the project stops competing solely on price and enters a more solid category: experiences with purpose and intelligent design.
Why modular construction enhances water management
One of the main advantages of modular architecture lies not only in how projects are built, but in how they are conceived from the outset. In terms of water management, this difference is critical.
In traditional construction, water-efficiency solutions are often addressed in later project stages, when many structural decisions have already been made. By contrast, the modular approach enables the water strategy to be defined in the design phase, evaluating consumption, routing, and potential optimization systems before fabrication begins.
At SIAN, water planning is part of the project conceptualization process. This makes it possible to:
• Analyze site context and water availability
• Design spaces with consumption efficiency and responsible resource use in mind
• Define from the beginning which solutions can be coherently integrated according to project type, climate, and operational model
This approach reduces improvisation, avoids rework, and ensures that every technical decision aligns with the project’s overall vision.
Modularity does not mean all projects use the same systems; rather, each solution is evaluated and adapted on a case-by-case basis, based on client objectives and environmental conditions. This is especially relevant in micro-resorts, where scale, initial investment, and operations must remain balanced.
Thanks to its design methodology and multidisciplinary coordination, SIAN can anticipate these variables before construction begins, ensuring that water management is coherent, realistic, and scalable—without compromising aesthetics or the guest experience.
Designing today for tomorrow’s resilience
Water is not just an operational resource. It is the foundation of resilience, sustainability, and long-term viability for hospitality projects in nature.
Investing in rainwater harvesting and greywater reuse reduces costs, decreases dependence on external supply, and strengthens the narrative of responsible tourism. Modular architecture amplifies these benefits by allowing water solutions to be integrated from the outset, without rework or improvisation.
At SIAN, every module is designed with a clear conviction: innovation is not about adding complexity, but about making better decisions from the start. In this way, each cabin or micro-resort serves as an example of how to care for water, preserve the landscape, and deliver a truly sustainable luxury experience.
