Water and Sewer Line and Related Structures Construction
Size Standard: $45 million
NAICS code 237110 covers Water and Sewer Line and Related Structures Construction, a critical infrastructure category in government contracting. This industry includes establishments primarily engaged in the construction of water and sewer lines, mains, pumping stations, treatment plants, and related structures such as storage tanks.
Government agencies at all levels invest heavily in water and sewer infrastructure. The U.S. Army Corps of Engineers builds major water infrastructure projects. The Environmental Protection Agency funds water and sewer projects through grants and loans. Military installations require extensive water and sewer infrastructure. State and local governments receiving federal funding for water projects use this code.
Contractors under NAICS 237110 must understand environmental regulations, water quality standards, and specialized construction techniques for pipelines and treatment facilities. Trenchless technology, pipe rehabilitation, and water treatment plant construction require specific expertise. Davis-Bacon prevailing wages apply to federal projects.
The $45 million size standard reflects significant infrastructure project requirements. Environmental compliance, particularly during construction, is critical. Experience with EPA-funded projects, state revolving fund requirements, and environmental permitting distinguishes successful contractors.
