Backwater Valve Subsidy application process updated
The Backwater Valve Installation Subsidy page now shows revised application instructions and supporting resources, including new homeowner and contractor guide links, a disclaimer, and updated submission steps using Dropbox, email, mail, and in-person drop-off. The required package now emphasizes a signed application and waiver, an itemized paid-in-full invoice, permit and inspection proof, and contractor confirmation that stormwater connections are not connected or have been disconnected; the page also states that applications must be submitted within one year after the work is completed. The program terms still show 50% coverage of eligible materials and labour, with a maximum subsidy of $1,600 for work completed after July 15, 2024 and $675 for work completed on or before July 15, 2024. External backwater valve installations remain ineligible, and the contact/submission email basementfloodingsubsidy@halton.ca is now repeated in the application instructions and Dropbox help text.
