LEININGER ENTERPRISES, LLC

Leininger Enterprises, LLC specializes in civil infrastructure construction and maintenance for federal installations, with deep expertise in water and sewer system rehabilitation, site preparation, and structural support systems. The company delivers precision execution for dam safety upgrades, including hydraulic line replacements, backflow prevention valve installations, and streambank restoration in sensitive aquatic environments. Their technical capabilities extend to the fabrication and installation of prefabricated metal structures for generator enclosures, lift station replacements, and horizontal lifeline safety systems, demonstrating proficiency in both civil engineering and facility integration. They also provide specialized landscaping services tailored to federal land management needs, including foliar treatment and erosion control, ensuring compliance with environmental regulations on military and public works sites. The contractor maintains a consistent and trusted relationship with the Department of Defense, particularly the U.S. Army Corps of Engineers, delivering mission-critical infrastructure services at dam and lake facilities across Ohio. Their work supports water resource management, flood control, and operational readiness at Army Corps-managed sites, reflecting a strong alignment with federal infrastructure resilience priorities. A single contract with the Department of Agriculture further confirms their ability to execute heavy civil engineering projects on non-defense federal lands, such as erosion control and watershed protection initiatives. Leininger Enterprises primarily operates within NAICS 237110 (water and sewer line construction), 238910 (site preparation), and 561730 (landscaping services), positioning itself as a niche provider of integrated civil works solutions for federal water resource infrastructure. Their focus on hydraulic systems, structural support, and environmentally sensitive site work distinguishes them in the defense and public works markets. As a Women-Owned Small Business and Woman-Owned Business certified contractor based in Hillsboro, Ohio, Leininger Enterprises leverages its local presence and federal certifications to deliver responsive, compliant, and technically rigorous services across the Midwest. Their business model emphasizes agility, regulatory adherence, and hands-on execution in remote and mission-critical environments.
