MayDay Water Preserver™ 55-Gallon Concentrate – 5-Year Potable Water Storage Solution

Water Preserver™ is the first and only product of its kind to be laboratory-tested and registered by the U.S. Environmental Protection Agency (EPA Reg. No. 61428-1) specifically for 5-year potable water storage. This certification confirms the product meets rigorous federal safety and efficacy standards for killing bacteria, viruses, mold, and fungus in a sealed environment. For procurement officers, this EPA registration provides a necessary layer of liability protection and ensures compliance with institutional emergency preparedness mandates. The formula has undergone over 30 years of field testing and remains the recognized standard for municipal and global relief organizations. Utilizing a registered disinfectant is critical for maintaining high-authority safety protocols in healthcare and government facilities.

Water Preserver™ significantly reduces the Total Cost of Ownership (TCO) by extending the water replacement cycle from six months to five years, eliminating the labor-intensive cost of semi-annual water rotations. Traditional maintenance requires facility managers to drain, clean, and refill high-capacity drums twice per year, which consumes significant man-hours and water resources. By switching to a 5-year cycle, an organization can reduce its maintenance labor costs by approximately 90% over a 10-year period. This efficiency allows for the reallocation of maintenance budgets toward other critical infrastructure and disaster recovery priorities. Additionally, the reduction in water waste supports institutional sustainability goals while ensuring constant operational readiness.

To maintain the guaranteed 5-year efficacy, Water Preserver™ must be used in new or scientifically cleaned heavy-duty plastic (polyethylene) water storage drums. While the proprietary stabilized formula is highly effective, using contaminated or non-food-grade containers can lead to the premature depletion of the active disinfecting agents. The product is specifically engineered for use in opaque 55-gallon barrels that protect the treated water from UV-induced chemical degradation. Technical specialists should ensure that any previously used containers are thoroughly sanitized to remove biofilms before application. Following these material guidelines ensures the proprietary chlorine-based formula maintains its required residual level for the full 60-month duration.

Each bottle of Water Preserver™ concentrate is precisely formulated to treat one 55-gallon drum of water, requiring a simple "pour-and-seal" application for maximum disinfection. The protocol begins by filling a clean 55-gallon drum with potable water, leaving a small amount of headspace, and then adding the entire contents of the concentrate bottle. Once applied, the drum should be sealed tightly to prevent the introduction of new microorganisms or airborne contaminants. This specific dosage ensures that the stabilized sodium hypochlorite reaches every part of the container to kill existing waterborne pathogens. Proper documentation of the treatment date on the drum is recommended to track the 5-year expiration window accurately.

Water treated with Water Preserver™ is classified as potable and safe for immediate consumption, cooking, and hygiene without the need for secondary filtration or boiling. The product is engineered to keep stored water at a "ready-to-use" standard, which is critical during emergencies when power or filtration infrastructure may be offline. It effectively eliminates the risk of waterborne illnesses by maintaining a sterile environment within the storage vessel for the entire 5-year shelf life. This immediate accessibility makes it a vital resource for clinicians, emergency responders, and safety officers during disaster recovery operations. Because the formula is pH-balanced and stabilized, the water remains clear and odorless, ensuring it is palatable for long-term emergency use.
