About the company
Kotobuki Kankyoh Kizai Co.,Ltd., a Japanese for-profit environmental infrastructure maintenance company based in Osaka, operates as a prime contractor providing wastewater and runoff treatment facility maintenance and inspection services exclusively to U.S. military installations in the Pacific region, with 100% of recent awards directed toward Navy and Army facility management customers.
The vendor holds a single-award indefinite delivery contract (N4008417D7000) with Navy Installations Command valued at $421,782 through May 2027, under which it has issued seven delivery orders totaling approximately $430,000 in combined potential value for recurring and non-recurring maintenance at Building 961 wastewater treatment plant, Naval Air Facility Misawa, Japan.
