UNSPSC 72141131: Water reservoir construction service

Construction of infrastructure for water storage

UNSPSC 72141131 Water reservoir construction service is a Commodity code that covers design-build and construction management services for water storage and supply infrastructure projects, as well as associated dam, stormwater detention, and drainage system work. State and local procurement activity under the code spans state departments of transportation and environmental service agencies, county water utilities, municipal water departments, and independent school districts. The work being solicited includes construction of new storage reservoirs (concrete tanks to AWWA D110 specifications), demolition and reconstruction of dam gate systems with automated remote monitoring, stormwater detention basin excavation and grading with associated piping and drainage infrastructure, landfill cell construction with geosynthetic liners and leachate collection systems, and related site improvements. Representative recent solicitations include West Jordan City's pre-qualification RFQ for a Zone 5 North 4.0 megagallon buried concrete water storage reservoir (SOQs due July 7, 2026, with bids anticipated August 2026 and completion November 2027); the State of Oregon's RFP for Construction Manager at Risk services on the Geren Island Flow Maintenance Project (proposals due August 18, 2026); and the Macon-Bibb County Board of Commissioners' sealed-bid solicitation for design-build automated gate system upgrade at Lake Tobesofkee Dam (bids due March 26, 2026, with 30-day completion timeline and $250 daily liquidated damages for delays).

Geographic activity centers on the West, Mountain, and Southeast regions, with solicitations posted from Oregon, Utah, Georgia, Maryland, Kentucky, and other jurisdictions. Issuers range from state transportation and environmental service agencies to city water utilities and county engineering departments. West Jordan City's reservoir project mandates ten years of reinforced concrete water tank construction experience, completion of at least two prior AWWA D-110 Type 1 projects of 3 megagallons or greater within eight years, current Utah E100 licensing, $2 million general liability insurance with full bonding capacity, and designated project personnel with matching experience. The Macon-Bibb procurement emphasizes experience (35 evaluation points) and includes local preference rights within five percent of the lowest responsive and responsible bid. Insurance requirements are consistent across solicitations, typically $1,000,000 general liability combined single limits with the issuing body named as additional insured. Performance and payment bonds equal to 100 percent of contract value are standard upon award for all design-build and construction contracts.
