PSC Z1PC: Maintenance of Water Supply Facilities — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC Z1PC (Maintenance of Water Supply Facilities).

Product and Service Code (PSC) Z1PC — Maintenance of Water Supply Facilities — is an official federal procurement classification within Portfolio Z — Maintenance, Repair, and Alteration of Real Property managed by the General Services Administration (GSA) under the Federal Procurement Data System (FPDS) Product and Service Codes Manual. Across federal agencies, contracting officers obligate approximately $890 Million annually under PSC Z1PC, with 140+ Bids active solicitations, pre-solicitation notices, and task order RFQs circulating on SAM.gov and agency e-Buy portals. While a 6-digit NAICS code defines a contractor's overall industry and Small Business Administration (SBA) size standard, PSC Z1PC specifies the exact real property maint (z1) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC Z1PC is most frequently paired with Primary NAICS 237110 (Water and Sewer Line and Related Structures Construction), which carries an SBA small business size standard of $45.0 Million. Major buying commands—led by Department of Defense (54% of spend), Department of the Interior (24%), and Indian Health Service (12%)—use PSC Z1PC to categorize statements of work encompassing Water Storage Tank Inspection, Cleaning, Cathodic Protection & Interior Relining; Water Well Rehabilitation, Submersible Pump Servicing & Chlorination Maintenance; and Backflow Preventer Testing, Fire Hydrant Flushing & Leak Detection Surveys. Understanding how contracting officers cross-walk PSC Z1PC with NAICS 237110 is critical because many agencies filter dynamic small business searches, GSA e-Buy distributions, and historical FPDS incumbent spend analyses by PSC rather than NAICS alone. Procurement teams issuing awards under PSC Z1PC utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as USACE / DoD. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC Z1PC competitions to certified small businesses—including 8(a) Business Development participants, Service-Disabled Veteran-Owned Small Businesses (SDVOSB), Women-Owned Small Businesses (WOSB), and HUBZone firms. Offerors responding to PSC Z1PC RFPs must demonstrate strict compliance with applicable FAR and DFARS clauses, deliverable quality standards, and supply-chain or labor regulations. For contractors expanding across both federal and state/local (SLED) markets, PSC Z1PC maps directly to NIGP Commodity/Service Code 913-60 (Construction, Water System, Mains, and Treatment Plants) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts. InTandem's automated government contracting platform continuously monitors live SAM.gov notices tagged with PSC Z1PC alongside matching state and local NIGP 913-60 bids, enabling capture teams to uncover hidden opportunities and generate compliant proposals faster.
