About AIWSE
This is an association run and contributed to by and for its members.
The association was formed in January 2020 by local water softener companies to improve, share knowledge and promote training within their businesses.
Membership is open to companies where their main business is water treatment and the selling, installation and servicing of water softeners directly to customers within their given areas.
We believe this collaboration between water treatment members is the best way to grow and help each other.

Since 2020
