To Whom It May Concern
In December of 1997 our department engaged Environmental Biotech in a test to determine if their services could help the City of Waltham and the sewer FOG problem. At that time the accumulation of FOG in a number of points within the sewer system required frequent and costly mechanical cleaning. At several locations, weekly or bi-weekly cleaning was required.
Organic solvents, as well as dry and liquick spore bacteria, had been tested with no success. So there was great skepticism that Environmental Biotech solutions could perform to our requirements.
During the initial test, CCTV inspections after one month of treatment at the test locations showed no new grease deposits and a softening of the existing hardened grease deposits. CCTV inspection three months after test initiation revealed unqualified success of the Environmental Biotech program.
Since the conclusion of the initial test in the spring of 1998, the City of Waltham has continuously used Environmental Biotech, and will do so for the foreseeable future. Environmental Biotech FOG control system prevent the accumulation of FOG at problem locations within the city sewer lines and lift stations.
From time to time, the department performs CCTV inspections at the treated locations to confirm the ongoing positive resutls. Those inspections show uniformly positive results at significantly reduced cost compared to the previously required mechanical cleaning.
The City of Waltham remains extremely pleased with the business relationship with Environmental Biotech. I am happy to recommend their services. Please feel free to contact me for further information.
Sincerely,
