About Onsite Management Inc.
Onsite Management Inc., a for-profit Subchapter S corporation based in West Chester, Pennsylvania, provides septic system repair, replacement, and pumping services to the federal government as a prime contractor operating entirely on small-business set-asides under NAICS 562991 (Septic Tank and Related Services) and related wastewater infrastructure categories. The vendor holds no federal vehicle positions and operates exclusively with a single customer, the National Park Service Northeast Region, on four small-business reserved purchase orders valued at $289 thousand combined potential value.
Onsite Management Inc.'s federal footprint is narrowly concentrated at Valley Forge National Historical Park in King of Prussia, Pennsylvania. The vendor has executed four contracts since March 2024: a $150.6 thousand firm fixed-price multi-year pumping services agreement running through March 24, 2029 (exercised at Option Year Two), with scope covering monthly pumping of approximately 270,000 gallons annually from nine holding tanks and periodic pumping from thirteen septic tanks; an $88.3 thousand rehabilitation contract awarded July 15, 2024 for Lower Lot Lift Station reconstruction including two new 5-horsepower grinder pumps, stainless-steel piping and fittings, and control panel replacement; a $27.75 thousand emergency repair and replacement contract at Furnace House awarded September 5, 2025, scheduled for completion April 25, 2026; and a $22.25 thousand emergency septic system repair contract at Walnut Hill House awarded April 13, 2026, completing August 28, 2026. All four awards carried Total Small Business set-asides. Activity has been episodic—two awards in 2024, one in 2025, one in 2026—with only one award ($22.25 thousand) completing within the next twenty-four months. The multi-year pumping contract extending through 2029 anchors the vendor's revenue continuity with the park, while emergency repair work has filled gaps on an as-needed basis. Onsite Management Inc. maintains no subcontracting relationships or multi-agency footprint in the source data.
