The Change

Due to current and potential power outages associated with severe weather, the Honolulu Board of Water Supply (BWS) is once again requesting all Oahu customers to conserve water. As of February 9, 2026, this voluntary conservation is a critical measure to ensure the stability of the island's water system during periods of potential infrastructure stress caused by extreme weather events and their associated utility disruptions.

The BWS typically issues such requests in situations where power outages could disrupt pumping stations and treatment facilities, thereby impacting the ability to deliver water to consumers. While this is currently a request, prolonged or widespread outages, coupled with inadequate water conservation efforts, could escalate to mandatory restrictions. These restrictions, if implemented, could involve limitations on non-essential water use, impacting business operations directly.

Who's Affected

This proactive water conservation request from the BWS has direct implications for a wide range of Oahu businesses:

Small Business Operators (Restaurants, Retail, Services)

Restaurant owners, in particular, face immediate challenges. Reduced water pressure or availability can halt dishwashing, impact food preparation, and affect restroom facilities, potentially leading to temporary closures or significantly reduced service capacity. For retail and service businesses, while water usage might be lower, restroom facilities, cleaning protocols, and any specialized water-dependent services (e.g., car washes, laundromats) will be affected. The cost of water-efficient fixtures or implementing new water-saving practices can be substantial, especially for smaller businesses with tight margins. Non-compliance risks fines or escalating restrictions.

Real Estate Owners (Property Owners, Developers, Landlords, Property Managers)

Property owners and managers must contend with potential tenant dissatisfaction if services are impacted. Beyond individual tenant concerns, widespread power outages linked to severe weather can compromise essential building systems that rely on water, such as fire suppression systems. Furthermore, the BWS's dependency on power grid stability means that prolonged weather events can create a dual threat: power loss affecting water delivery, and water scarcity impacting building operations. Developers may need to factor in increased lead times or altered construction practices if water availability becomes a consistent concern.

Tourism Operators (Hotels, Tour Companies, Vacation Rentals)

Hospitality businesses are on the front lines of this request. Hotels rely heavily on water for guest rooms (showers, toilets), laundry services, swimming pools, and culinary operations. Reduced water pressure or availability can directly impact guest experience and operational efficiency. Tour companies might need to adjust offerings if water-dependent activities are affected. Vacation rental hosts face direct customer service challenges if amenities are compromised. While initial compliance is voluntary, any move to mandatory restrictions could severely disrupt bookings and operational capabilities, leading to revenue loss and negative reviews.

Agriculture & Food Producers (Farmers, Ranchers, Food Producers, Aquaculture Operators)

For businesses in the agricultural sector, water is not just an operational necessity but the core of their product. Farmers and ranchers are highly vulnerable to any restrictions on water use, as it directly impacts irrigation, livestock watering, and crop yields. Aquaculture operators are critically dependent on stable water flow and quality. The inability to access sufficient water can lead to crop failure, livestock distress, and significant financial losses. This request, while currently voluntary, highlights the fragility of water supply in extreme weather scenarios and the need for robust water management strategies and backup solutions.

Healthcare Providers (Private Practices, Clinics, Medical Device Companies, Telehealth Providers)

Hospitality businesses are on the front lines of this request. Hotels rely heavily on water for guest rooms (showers, toilets), laundry services, swimming pools, and culinary operations. Reduced water pressure or availability can directly impact guest experience and operational efficiency. Tour companies might need to adjust offerings if water-dependent activities are affected. Vacation rental hosts face direct customer service challenges if amenities are compromised. While initial compliance is voluntary, any move to mandatory restrictions could severely disrupt bookings and operational capabilities, leading to revenue loss and negative reviews.

Second-Order Effects

This water conservation request, driven by severe weather and potential power outages, initiates a cascade of economic impacts across Oahu's island economy:

• Water Conservation Measures → Reduced Water System Strain → Lower Pumping Costs → Stable Utility Rates (Short-term): While businesses incur costs in adopting conservation, successful collective action alleviates immediate strain on BWS infrastructure, potentially averting more drastic measures and associated emergency repair costs that could influence future rate hikes.

• Power Outages → Water System Disruption → Conservation Request → Operational Downtime for Businesses → Reduced Consumer Spending → Slower Local Economic Activity: Extended power outages that necessitate water conservation can halt business operations, leading to lost revenue. This slowdown in business activity directly reduces consumer spending, impacting ancillary businesses and the broader local economy.

• Increased Need for Water-Efficient Technology → Higher Upfront Costs for Businesses → Potential Price Increases for Goods/Services → Impact on Consumer Affordability → Reduced Competitiveness for Tourism: Businesses investing in water-saving equipment face immediate capital expenditure. If these costs are passed on to consumers, it could increase the price of goods and services, potentially making Oahu a less affordable destination for tourists and impacting the purchasing power of local residents.
