Niagara Falls backwater valve rebate: the WRAP rule card.

The City of Niagara Falls Weeping Tile Removal Assistance Program (WRAP) pays up to $4,000 at 100% of eligible costs for weeping tile disconnection and a sump pump, and up to $1,200 at 100% for a backwater valve. The rule that catches people off guard: a preliminary City inspection has to happen before any work begins, and the approval it grants expires six months later.

What the program pays

Weeping tile disconnection and sump pump work is reimbursed at 100% of eligible costs, including taxes, to a maximum of $4,000. A backwater valve is a separate rebate, also at 100% including taxes, to a maximum of $1,200. Both are paid at 100% of cost, not a percentage-shared-cost model like Toronto's 80% or the St. Catharines and Welland programs. A rebate is granted once per property. Rebates are granted on a first-come, first-served basis and are subject to available funds, so meeting the eligibility rules does not by itself guarantee a rebate will be paid.

Two conditions that disqualify a property before inspection

A property that already has a backwater valve is not eligible for the backwater-valve rebate item. A property that already has a sump pump discharging foundation drainage to the ground surface is not eligible for the weeping-tile/sump-pump rebate item. The program funds new installation, not upgrading or replacing existing equipment.

The inspection-and-expiry sequence

A preliminary City inspection must confirm eligibility before any work is arranged; do not book a contractor until it is done. The approval that inspection grants expires six months after the City's application review date, so the permit, contractor work, and City post-work inspection must all happen inside that window, or the approval lapses and the process restarts.

A failed installation is not reimbursed

If, after investigation, excavation, or other work, it turns out a sump pump or backwater valve cannot actually be installed, the costs of that investigation, excavation, or other work are not eligible for rebate. Discharge is also restricted: a sump pump must discharge to the exterior ground surface only, never onto a neighbouring property, sidewalk, or road.

Eligibility, in general terms

The property must be connected to the municipal sanitary sewer system, and the program is open to single-family detached or semi-detached homes only; multi-residential and condominium properties are not eligible. One City permit for the plumbing work is required before work begins (the City's WRAP page calls it both a building permit and a plumbing permit; in 2026 it is a $243 flat fee), and the City Building Department inspects the work before the rebate is issued. Confirm your specific property's status and the current application details directly with the City.

This page covers the WRAP rebate itself. The Ontario Building Code rule behind a backwater valve, the semi-detached one-valve-per-side requirement, and the City's own 2026 permit fee for this work are covered separately: see the Niagara Falls backwater valve: Building Code and permit fee guide.
