This project consists of replacing the existing 4 KTurbo aeration blowers with new Aerzen hybrid units. The project also includes the installation of an evaporative cooling system and modifications to the aeration piping for each blower. A preliminary estimate for the total cost of this project is $1,075,000. Please see cost per item Blowers - Aerzen Hybrid (4): $530,000 Installation: $132,500 Electrical: $20,000 Miscellaneous 20%: $136,500 HVAC in Blower Room: $31,500 Engineering Design: $127,000 Contingency: $97,500 Project Total: $1,075,000 New An engineering study was completed last fiscal year that identified operational issues and inefficiencies with the current turbo blowers used at the plant for aeration. The existing blowers are 10 years old and nearing their end of useful life, no longer serviceable by the manufacturer, and replacement parts are not very limited. New hybrid blowers will reduce operating and maintenance costs, improve reliability, and increase efficiency at the plant.
