The amounts below are program maximums as listed on the official City page reviewed November 12, 2026. The City reimburses the lesser of the applicable maximum and eligible work cost. Eligibility and payment are not guaranteed.
Maximums listed by Ottawa
| Eligible category | Listed maximum |
|---|---|
| Indoor sanitary backwater valve | $1,000 |
| Indoor storm backwater valve | $1,000 |
| Outdoor storm backwater valve | $2,500 |
| Plumbing permit fee (plumbing work only) | 100% of current fee |
These are ceilings, not standard payment amounts. For each eligible item, the City pays no more than the applicable maximum or eligible work cost, whichever is less. Confirm whether each cost is eligible with the City.
Conditions to check before arranging work
The official program page describes residential units within the City of Ottawa and includes construction-date criteria that differ by system:
January 1, 2004
January 1, 2012
- The protective plumbing device must not have been installed by the City.
- A plumbing building permit is part of the program requirements; verify what applies before work.
- The City states work must be complete and the application received within 18 months of permit issue. This 18-month period took effect July 1, 2026.
- City decisions depend on the complete criteria and the individual application; this guide cannot establish qualification.
A practical application sequence
- Confirm the category. Establish whether the proposed installation is sanitary or storm and whether it is indoor or outdoor with a qualified plumbing professional.
- Check before work. Read the City's current program and permit guidance; confirm eligibility, timing and required permit before arranging work.
- Keep evidence as the project proceeds. Record the permit issue date, retain inspection documentation, and ask for a paid itemized installation invoice.
- Submit through the City. Use the official online application and its current checklist. The City identifies ownership proof, permit/inspection report and paid itemized installation invoice; verify the latest submission requirements.
- Wait for the City's review. Do not assume that submission, permit issuance or an installer’s opinion guarantees eligibility or payment.
What the program does not cover
The City page excludes rebates for maintenance, repair and replacement. A program maximum also does not mean every project cost is eligible. If your situation involves existing equipment or mixed work, ask the City whether any portion fits the current program before relying on a rebate.
Program details can change. The official City source and online application are the authoritative place to confirm current criteria, records, deadlines and submission steps.
