Our detention tank packages are designed for quick installation and come with everything the City requires—no guesswork. If you need help choosing the right setup, I’m just a call or email away.
Starting July 1, 2025, the City of Vancouver requires most new homes—and some major renovations—to include an on-site rainwater detention system. These complete detention tank packages are designed specifically to meet the City’s new rainwater management regulations under the Small Site Pathway.
Each package includes a shallow-depth GRAF Platin detention tank, orifice flow control, overflow, trap, and backwater valve—everything needed to meet active storage and drainage requirements based on your lot size.
