1. Operation and maintenance of wastewater treatment plants;
2. Preventative maintenance, repair, and alteration of incinerator plants;
3. Calibration of weight scales;
4. Cleaning and disinfection of potable water tanks;
5. Management of sewage treatment facilities and sewer lines;
6. Execution of critical utility projects as outlined in the Fiscal Year 2026 Maintenance Execution Plan (MEP);
7. Addressing unforeseen non-recurring task order modifications and unanticipated repairs exceeding standard service order thresholds.

Period of Performance
The contract is set to be performed over a period that includes one base year and four option years, with ongoing operations expected until at least May 31, 2026, followed by a bridge contract extending through June 1, 2027.

Place of Performance

Bidder Requirements
Bidders must possess specific non-transferable licenses issued by the Government of Japan (GOJ), including a Special Construction License for Machinery, Piping, and Electrical work, as well as multiple local prefectural permits for industrial waste disposal. Only entities legally registered in Japan can obtain these licenses, which are essential for performing construction work and managing waste disposal obligations.

Incumbent Analysis (see Incumbents section for more detail)
This modification appears to have a confirmed incumbent based on prior work under Contract N4008420D0402 awarded to Nikken Sogyo Co., Ltd. valued at $53,889,007 (05/28/20–05/31/26), with recurring maintenance responsibilities that closely match the current scope, including incinerator plant equipment/system maintenance, calibration of weight scales, operation and maintenance of sewage treatment facilities and sewer lines, wastewater treatment system painting, and cleaning/disinfection of potable water tanks. Additional related tasking under the same contract includes bridge/extension obligations (e.g., N4008420D0402-N4008425F0076) and other repair/overhaul efforts at similar Yokosuka-area facilities, indicating continuity of the same service lines.
