Downspout Disconnection

Redirecting roof runoff from the sewer system

Infiltration Planters

Infiltration planters work well in space limited sites with good drainage

Pervious Pavers

Pervious pavers allow stormwater to soak into the ground and reduce runoff

Soakage Trenches

Shallow lined trenches treat stormwater runoff from hard surfaces
