Global Water Technologies and Psychrometric Systems Awarded $4.5 Million Contract To Reduce River Water Thermal Pollution in Mexico.

GOLDEN, Colo.--(BUSINESS WIRE)--Sept. 22, 1999--

Global Water Technologies, Inc. (OTCBB:GWTR) today announced that its wholly-owned subsidiary, Psychrometric Systems, Inc. (PSI), has reinstated a contract with Consorcio Azucarero Escorpion, S.A. de C.V. (CAZE) which calls for PSI to supply technology and equipment for cooling water at three of CAZE's sugar refineries in Mexico. The equipment is scheduled for delivery during the last half of 1999. The contract, which had an initial value of approximately $4.2 million, has now been increased to $4.5 million.

The equipment to be supplied by PSI will reduce CAZE's dependence on river water as well as reduce thermal pollution of the Mexican water sources typically utilized by industry in Mexico for process cooling water. PSI is a leader in the industry, having installed similar technology and equipment at plants to help companies address the growing concern over thermal pollution of the world's waterways.

GWTR is currently in discussions with other major industrial water users worldwide to help lessen their dependency on public waterways and decrease thermal pollution. Federal, state and local governments are becoming more aware of the environmental impact caused by thermal pollution and, therefore, are becoming more stringent with thermal discharge guidelines and the imposition of penalties.

George Kast, President and Chief Executive Officer of GWTR, commended CAZE for their efforts in reducing thermal pollution of the Mexican rivers and being a leader in Mexico for their environmental awareness.

Global Water Technologies, Inc. through its subsidiary Psychrometric Systems, Inc., provides process cooling water primarily through the design, engineering and construction of cooling towers to industrial and manufacturing clients worldwide. Applied Water Technologies, Inc., a wholly owned subsidiary of GWT, provides its customers with proprietary non-chemical, water treatment systems and water reclamation designed to meet the growing need for water purification re-use worldwide.
