About This Program
The Grant Map catalogs Iowa Onsite Wastewater Assistance Program in its Iowa City, IA research directory. The record carries audience tags for homeowners; those tags do not establish eligibility or current service coverage.
OSWAP is a low-interest loan, not a grant. It can finance up to the actual eligible cost of replacing or improving a failing onsite wastewater system for an existing home that cannot connect to public sewer. The county must approve the system and issue the permit, and a participating lender must approve the borrower. The published rate and term are ceilings, not guaranteed terms for every applicant.
A participating lender determines credit approval and final terms after county system approval
