Wetlands are an ideal technology for:
- Text A
- Text B
| Type A | Type B | Type C |
|---|---|---|
| Surface water | Minimal Any surface flow can be slowed with check dams |
Ponding is encouraged with check dams |
| Soil | Filter media required | Amendment preferable when possible |
| Underdrain | Common | Uncommon |
| Maintenance | Medium to high | Low |
| Stormwater benefit | High | Moderate |
| Biodiversity benefit | Increased with native planting | Typically lower |
Planning considerations[edit]
Design[edit]
Performance[edit]
STEP (under previous name SWAMP) conducted their own research into the performance of stormwater wetlands, the project page and report can be viewed here.
