Testimonial - Warrick County School Corporation

To Whom It May Concern:

United-Tech Indiana has been treating drains in our buildings for the past two years. Prior to contracting with United-Tech Indiana, our maintenance department regularly had to rout out our drains in the kitchens of our schools. Most of the drain clogs were due to grease being washed down the sinks. The bacteria treatment has completely eliminated the need for our employees to unclog the drains as the treatment has kept material in the drains in a liquid state. We have been very satisfied with Mr. Steurer and the treatment being used in our schools. We believe the treatment has freed our maintenance workers to use their time one other projects and the cost of United-Tech's applications has been money well invested.

In summary, I would recommend the BZT Waste Digester to anyone that is having problems with clogged drains.

Sincerely,

Jim Martin, Superintendent
Warrick County Schools
