"This letter serves as a business reference for Water Savings, Inc.  (WSI).  Since our relationship started in November, 1999, WSI has proven to have a successful program in tact.  WSI's Water Conservation Program has definitely worked for us here at Steward Tower Apartments.  

I cannot end this letter without first commenting on the response time to service calls.  WSI provides prompt next day service with qualified technicians.  Everyone at WSI has been courteous and helpful with all our needs.  As far as we are concerned, WSI can stand toe to toe with the best."
