1

Area Drain

Collects surface or stormwater from open areas

2

Backwater Valve

Used to prevent reverse flow in a drainage system.

3

Bioswale

Landscape channels that allow runoff water to be collected, conveyed, filtered and infiltrated into the soil.

4

Conductor

A pipe inside a building that conveys stormwater form the roof to an approved point of disposal. (e.g. storm drain or sewer)

5

Flow through Planter

A planter that receives discharge from gutters or drains so as to reduce the quantity/rate of stormwater leaving the site.

6

Foundation drainage

A perforated pipe buried in gravel or rock around the perimeter of a building that redirects groundwater away from the foundation of a building.

7

Leader

An exterior vertical drainage pipe for conveying storm water from roof or gutter drains.

8

Overflow Drain

A drain typically paired with a roof drain containing a 2” high dam allowing for secondary drainage if the primary roof drain becomes plugged.

9

Planter Drain

A drain in a permanent planter located inside or on a building where infiltration to the surrounding soil cannot occur. The planter drain usually consists of a drain body cast in the planter with a perforated pipe riser that extends above the soil level acting as an overflow for the planter.

10

Rainwater Harvesting

The practice of capturing, infiltrating or utilizing rainwater from roofs, parking lots and patios.

11

Roof Drain

A drain installed to receive water collecting on the surface of a roof and to discharge it to a leader, downspout or conductor.

12

Sand Interceptor

A device designed to separate and retain sand and sediment from normal stormwater.

13

Scupper

A hole in the ships side to carry water overboard from the deck or an outlet in the side of a building for draining water.

14

Siphonic Drainage

A system that relies on suction generated downstream in the pipe to draw water through the drain at full bore and at higher velocities.

15

Trench drain

A linear drain that when used for storm drainage is typically found at the base of a ramp.
