Subject category: utility
Title: Control Tank
Feature Count: 0
Feature Type: Line
Abstract: Tank Component Types---Wet (Permanent Pool): A tank that features a permanent pool of water. They are designed to optimize water quality by providing long retention times (on the order of a week or more) to settle out particles of fine sediment to which pollutants such as heavy metals adsorb, and to allow biologic activity to occur that metabolizes nutrients and organic pollutants.---Infiltration: A tank that is designed to use the hydrologic process of water soaking into the ground (commonly referred to as percolation) to dispose of stormwater.---Detention: Detention tanks temporarily store stormwater and typically releases flow over a few hours or a few days.---Combined (Wet and Detention): Detention tanks contain a permanent pool of water, but also have volume for temporary storage beyond the permanent pool.
Purpose: Tanks are closed stormwater features typically round or half-round section, constructed of metal or plastic. Which are used to hold or treat stormwater.

Attribute Information

ItemDescriptionDomain
_DBAssetID_DBAssetID is the unique identifier that is used to tie to Cityworks, MIS, or some other database. The DBAssetID is unique for each feature class and is generated by a script that runs nightly. Users should not modify the DBAssetID.
_UpstreamDBAssetID_UpstreamDBAssetID tracks the DBAssetID of the feature on the upstream end of the closed conveyance feature.
_DownstreamDBAssetID_DownstreamDBAssetID tracks the DBAssetID of the feature on the downstream end of the closed conveyance feature.
_ComponentType_Within the Puget Sound Stormwater Infrastructure Framework, Component Type is the finest classification for a structure.
Combined
Detention
Infiltration
Unknown
_Diameter_Diameter is the interior diameter of the tank, in inches. Diameter is recorded when the pipe is circular in shape.
_Width_Width is the distance from one side of a pipe to the other side. Width is collected when the pipe is not circular in shape.
_Height_Height is the distance from the top of a pipe to the bottom. Height is collected when the pipe is not circular in shape.
_MeasSource_MeasSource is the source of the Diameter, WidthA/WidthB, CoverSize, Depth and Sump Depth measurements.
