Matched, not listed

Describe your company once. Captivaq scores every new notice against your capabilities, locations, and set-asides.

Earlier than the RFP

Forecasts and sources sought notices surface months before the solicitation, while you can still shape the win.

A draft, not a link

For the bids worth pursuing, it reads the solicitation and drafts the response with citations back to the source.

Questions people ask

What is NAICS 221310?

NAICS 221310 is the federal industry code for Water Supply and Irrigation Systems. Agencies attach it to solicitations for this work, and it decides which small business size standard applies.

Are these real government contracts?

Yes. Every row comes from the public feed of the official source, most often SAM.gov, and links straight to the official notice. Confirm deadlines and amendments there before you respond.

Will this page list every open Water Supply and Irrigation Systems bid?

No single search can. Agencies sometimes file this work under a neighboring code or describe it differently. Use this page to find leads fast, then check scope, eligibility, and attachments in the official notice.

How often is this page updated?

The list refreshes through the day from the same opportunity database that powers Captivaq. It currently tracks 20 open notices.

How do I hear about new ones without checking back?

Captivaq watches the sources against your company profile and alerts you when a fitting notice posts, then scores the fit and drafts the response. That is the product behind this page.
