Why Choose HASA?

Since 1964, HASA has pioneered the water treatment industry. Whether you are a homeowner dedicated to providing safe water for swimming, a pool service professional building a reputation for excellence, or a municipal manager overseeing a city's water supply, here’s why HASA is the partner you can trust.

Unmatched Purity and Potency

In pool operations, balanced water chemistry is the ultimate KPI. Store-bought alternatives often sit on shelves for months, degrading in potency.


HASA’s fully-integrated supply chain model ensures you receive the freshest liquid chlorine for pools, maximizing sanitization power. Additionally, our liquid chlorine for pools is filtered to remove impurities, protecting equipment and ensuring safe, clean, and clear pool water that homeowners love and pros can stake their reputation on.

Reliable Supply Chain for Critical Infrastructure

For municipal water management and industrial liquid chlorine needs, supply chain reliability is non-negotiable.


We operate a vertically integrated supply chain with multiple manufacturing and distribution facilities. Our self-owned supply chain helps ensure you get the high-quality water treatment chemicals you need on time, every time. HASA products also help you stay within budget by providing high-concentration products that require less volume to achieve the same results.

A Commitment to Sustainability

We are the only supplier operating under an active, verifiable sustainability model. Our signature 4x1 returnable-use program keeps millions of pounds of plastic out of landfills each year.


By choosing HASA, you are choosing a partner that prioritizes the health of the planet as much as the health of your water.
