About Total Water Treatment Systems, Inc.
Total Water Treatment Systems, Inc., doing business as Culligan Total Water Treatment Systems Inc., operates as a Madison, Wisconsin-based for-profit Subchapter S corporation providing high-purity water systems maintenance, repair, installation, and preventative services to federal agencies exclusively as a prime contractor, competing on an unrestricted, full-and-open basis with no set-aside designations across its footprint. The company holds no SBA certifications and carries no minority, disadvantaged, or veteran-owned designations. Total Water has maintained continuous federal contracting relationships since at least the mid-2000s, with established expertise in sterile processing water systems, dialysis water treatment systems, reverse osmosis systems, deionized water systems, and water softener maintenance across healthcare and industrial federal facilities.
Customer concentration is heavily skewed toward the Department of Veterans Affairs. VA accounts for 72% of Total Water's awards by count and 91% of combined potential value, anchored by Veterans Integrated Service Network 12's 28 awards valued at $2.9 million, which dominate both rankings. The Department of Agriculture Agricultural Research Service follows with 21 awards totaling $174 thousand in potential value, the Department of Justice Drug Enforcement Administration with 12 awards at $24 thousand, and the Department of the Navy Bureau of Medicine and Surgery with 6 awards at $203 thousand. Across 11 distinct customer agencies, Total Water maintains a narrow, healthcare-focused customer base where VA penetration creates material recompete risk — the agency is responsible for nearly all of the vendor's revenue base.
Total Water places recurring work under a single named IDC: VA69DP1533, an indefinite delivery contract through which 5 task orders have generated $481 thousand in combined potential value. The vendor's recent representative work includes a $411.2 thousand firm fixed-price purchase order from VA Network 12 for sterile processing and dialysis preventative maintenance at the Clement J. Zablocki VA Medical Center in Milwaukee running through September 2029; a $348.5 thousand purchase order from the same network for preventative maintenance of sterile processing and dialysis water systems at the Green Bay Community-Based Outpatient Clinic through August 2029; and a $151.3 thousand purchase order from USDA Agricultural Research Service for reverse osmosis system and Millipore polisher maintenance with a base year and four option years through March 2029.
Award volume has been sparse and flat — three awards per year in 2022 and 2023, rising slightly to five in 2024, then declining to two awards each in 2025 and 2026. Four awards carrying combined potential value of $96 thousand face ultimate completion inside the next twenty-four months. Total Water performs all work directly as a prime contractor with no documented subcontractor relationships, maintaining a lean operational posture centered on field maintenance and equipment service delivery at customer sites across the continental United States, with recent performance locations including Iron Mountain and Milwaukee, Wisconsin; Athens, Georgia; Ann Arbor, Michigan; and Naval Station Great Lakes, Illinois.
