Why it matters

Roof water has to go somewhere

A typical pitched roof sheds a large volume of water during a storm. Where that water lands shapes basement moisture, lot drainage, and the load on shared storm infrastructure.

Foundations stay drier

Water directed at least a couple of metres from the wall, onto sloped ground, reduces the pooling that drives basement seepage.

Captured water is reusable

Barrel water is suited to garden beds, lawns, and containers, easing demand on treated municipal supply during dry summer stretches.

Less runoff leaves the lot

Rain gardens and permeable surfaces let part of each storm soak in rather than rushing straight to the storm sewer.
