ALCOSAN: Addressing the Environmental Health of Our Region

Water. It’s our most precious natural resource. At ALCOSAN we believe our mission and our purpose is clear. That’s why we’re working hard everyday to provide you, our customer, with cost-effective, environmentally conscious wastewater treatment that protects the public’s health while enhancing usage of our natural resources.


 With Deepest Sympathy...

This holiday season, the unthinkable happened to a member of the ALCOSAN family.  Dan Thornton, Billing Supervisor in the Customer Service and Billing Department, was traveling to Florida with his family when their vehicle was struck from behind by a speeding tractor-trailer.  While Dan, his wife Susan, daughter Sarah and son Christopher each sustained serious injuries, the impact of the crash was fatal for three-year-old son, Sean.

As we extend our heartfelt condolences to Dan and his family, we ask that friends and co-workers touched by this tragedy also take a moment and offer a personal expression of sympathy and support.  All messages will remain private and will be collectively shared with the family at an appropriate time.  Messages may be submitted here.
