The City of Hamilton offers property owners of single-family residential homes a grant (subsidy) of up to $2000 for the disconnection of downspouts, installation of a backwater valve and other eligible works that help to reduce the risk of basement flooding. If downspout disconnections are completed by one of the pre-qualified contractors, either in conjunction with the installation of a backwater valve or not, the property owner will be eligible for a reimbursement of $75 per downspout. The grant maximum is $2000 for any of the combined eligible works under the Program. Learn more about this program.
