Revitalize Your Water, Rejuvenate Your Life
REVERSE OSMOSIS SYSTEMS
OUTDATED DRINKING WATER QUALITY STANDARDS
Receiving a passing grade from the federal government doesn’t necessarily mean the water aligns with the most current health standards. The legal limits for contaminants in tap water haven’t been updated in nearly 20 years and haven’t been reviewed in over 40 years.
The Clean Water Act of 1977 addressed only a limited range of pollutants, including conventional, non-conventional, and toxic substances. It extended compliance deadlines for industries acting in good faith and improved the industrial pretreatment program to protect municipal treatment plants. However, it didn’t focus on drinking water quality. Legal limits for drinking water have not evolved to reflect our updated understanding of how contaminants impact human health since the 1970s.

REVERSE OSMOSIS FILTRATION
Reverse Osmosis (RO) systems utilize membranes or microscopic filters that only allow small water molecules to pass. Tailored for regions with limited safe water, these systems also desalinate ocean water. The RO membrane’s microscopic pores effectively remove visible and dissolved contaminants, including those larger than water molecules. However, it may also eliminate healthy minerals. Many RO systems redirect water to mineral beds for added health benefits.

Spokane has emerged as a prominent center for life sciences, hosting numerous clinical trials and research endeavors. With its impressive array of 9 hospitals, two medical schools, and six higher education institutions, Spokane has cemented its status as a leading healthcare and innovation hub. Institutions in the life sciences sector rely on pure water for many applications, including research, patient care, and pharmaceutical production.
Agriculture
Agriculture is a cornerstone of Spokane’s economy, with approximately 7,000 farms and ranches contributing around $5 billion to the region and surrounding counties. RO systems play a crucial role in agriculture by eliminating harmful contaminants from water used for livestock, irrigation, food processing, and other agricultural activities.
IT/Energy
Spokane’s strategic location, characterized by its low susceptibility to natural disasters, is ideal for critical business services, particularly in the IT and energy sectors. Filtered water ensures risk-free energy management and server maintenance operations, where even minor impurities can lead to significant disruptions.
Manufacturing
The manufacturing industry is vital to Spokane’s economy, constituting 7.2% of the local economic activity. From paper and plastic to metal products and equipment, manufacturing facilities rely on softened water for various mechanical and chemical processes, particularly boiler systems.
Aerospace
Spokane is the fifth-largest aerospace cluster in the United States and the second-largest in Washington state. With over 120 businesses dedicated to the global aerospace industry, the demand for water meeting stringent quality standards is paramount. Reverse osmosis systems are instrumental in ensuring compliance with rigorous drinking water standards, maintaining coolant water quality to prevent metal corrosion, and fulfilling other critical requirements of the aerospace sector.
