On its SAM.gov registration, Water Illumination Inc meets the SBA size standard for these industries, so it can bid on small business set-asides that use them.
Open contracts in Water Illumination Inc's NAICS codes
240 open federal opportunities on SAM.gov use one of Water Illumination Inc's NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (women-owned (WOSB)). Here are a few, those in its primary code first, then those in California, then the soonest due.
Confirm eligibility first. Water Illumination Inc's women-owned (WOSB) status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: WOSB and EDWOSB set-asides need SBA WOSB program certification. SBA's Small Business Search shows a firm's current certifications.
