Flow-Thru BMPs
swales, media filters, sand filters, dry extended detention basin, etc.
Biofiltration BMPs
filled with treatment media and drainage rock that treat stormwater runoff by capturing and detaining inflows prior to controlled release
Retention BMPs
maximize storage and infiltration of stormwater runoff to prevent surface runoff
Stormwater Reuse
stormwater for treatment and non-potable water reuse.

Alleviating Localized Flooding
After 4 inches of surface mulch and plant material added. All rain now infiltrates in less than an hour
After 2 inches of rain fell in less than an hour on
high clay soils.

How Can You Be a Water Champion?
Become an advocate for DNPW systems Ensure all public dollars incorporate multiple benefits and equity elements Join the National Blue Ribbon Commission for Onsite Non-potable Water Systems
Support a vision of localizing our water
22
How Can You Be a Water Champion?
Asses the code framework for decentralized non-potable water systems
Ensure all codes and permitting are updated with best practices Support rebates and funds for decentralized non-potable water systems
