NAICS 237110 in numbers
The federal government buys water and sewer line construction through multiple agencies, with the Navy's facilities commands leading the volume. NAVFACSYSCOM Southwest, the Upper Colorado Regional Office, and DSC Contracting Services Division are the largest buyers. About 40 percent of awards go unrestricted, while 34 percent are set aside for small businesses under SBA programs. The remaining awards go to 8(a) firms, service-disabled veteran-owned small businesses, and other designated categories. Buyers range from regional offices managing specific watersheds to military installation support commands.
A firm entering this market should expect median awards around $21,300, though the top buyers have pushed much larger contracts. With 2,690 distinct vendors sharing nearly $16.84 billion over 27 years, competition is substantial but the market supports many players. The data shows 29,707 awards on record, indicating steady demand. Small businesses have real opportunity here: nearly 15,000 awards went to SBA and 8(a) set-asides, and another 490 went to service-disabled veteran-owned firms.
Watch for 302 contracts ending within the next 12 months worth $2.03 billion in total value. These represent recompete opportunities where incumbents may defend their positions and new vendors can bid. The 108 active notices signal ongoing procurement activity. Firms should monitor NAVFACSYSCOM Southwest and the Upper Colorado Regional Office closely, as these two buyers alone account for roughly $2.88 billion in historical awards and likely represent the steadiest pipeline for new work.
