Description: Local Pump Station - The Local Pump Station layer consists of points depicting non-District owned/maintained pump stations. Pumping stations, also called lift stations, are normally designed to handle raw sewage that is fed from underground gravity pipelines. Sewage is fed into and stored in an underground pit, commonly known as a wet well. The well is equipped with electrical instrumentation to detect the level of sewage present. When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main or rising main from where the sewage is discharged into a gravity manhole.

Description: Local Flow Regulating Structure - The Local Flow Regulating Structure layer consists of points depicting non-District owned/maintained flow regulating structure assets. A flow regulating structure is an asset built to regulate the velocity of flow for storage and control. Subtypes include: Automated Regulators, Fixed Weir Regulators, Fixed Weir Re-regulators, Backflow Devices, Hydrobrake Storage Control Facilities, Sanitary Flow Dividers, Sanitary Sewer Overflows, and Siphons.

Description: The District Odor Control Facility feature class consists of points depicting District owned/maintained odor control facililites. An odor control facility is a group structures and appurtenances that eliminateS tunnel odors produced by wastewater sewage.
Description: The District NPDES Permit Point feature class consists of points depicting District owned/maintained National Pollutant Discharge Elimination System Combined Sewer Overflow Permit locations within the collection system. A combined sewer overflow is the discharge of wastewater and stormwater from a combined sewer system directly into a river, stream, or lake.
Description: The District Monitoring feature class consists of points depicting components of any monitoring activities conducted by the District that resides in the Enterprise GIS. Monitoring components include flow meters, level monitors, and gain gauges. A flow meter is device used to measure the volume of wastewater usage over a period of time. A level monitor is an electronic device used to record the level of wastewater in a sewer main. A rain gauge is a type of instrument used to gather and measure the amount of liquid precipitation over a set period of time.
Description: The District Manhole feature class consists of points depicting District owned/maintained manhole or blind junction assets. A manhole is a vertical pipe that connects the sewer mains to the surface. Manholes are used for access to the sewer pipes for inspection and maintenance. A blind junction is where two or more sewer mains connect with no surface access.
Description: The District Flow Regulating Structure feature class consists of points depicting District owned/maintained flow regulating structure assets. A flow regulating structure is an asset built to regulate the velocity of flow for storage and control. Subtypes include: Automated Regulators, Fixed Weir Regulators, Fixed Weir Re-regulators, Backflow Devices, Hydrobrake Storage Control Facilities, Sanitary Flow Dividers, Sanitary Sewer Overflows, and Siphons.
Description: The District Floatable Control feature class consists of points depicting District owned/maintained floatable control facility assets. A floatable control facility is an asset that collects floatable material prior to discharges to streams or waterbodies.
Description: The District Drop Structure feature class consists of points depicting District owned/maintained drop structure assets. A drop structure is an asset built to decrease the velocity of flow by lowering the slope or grade; the drop in velocity promotes the deposition of silt and prevents excessive channel scour.
Description: The CSIAbandDistrictRegulator feature class consists of points depicting eliminated District owned/maintained flow regulating structure assets. A flow regulating structure is an asset built to regulate the velocity of flow for storage and control. Subtypes include: Automated Regulators, Fixed Weir Regulators, Fixed Weir Re-regulators, Backflow Devices, Hydrobrake Storage Control Facilities, Sanitary Flow Dividers, Sanitary Sewer Overflows, and Siphons.
Description: The CSIAbandDistrictPumpStation feature class consists of points depicting eliminated District owned/maintained pump stations. Pumping stations, also called lift stations, are normally designed to handle raw sewage that is fed from underground gravity pipelines.
Description: The CSIAbandDistrictPermitPoint feature class consists of points depicting abandoned or eliminated District owned/maintained National Pollutant Discharge Elimination System Combined Sewer Overflow Permit locations within the collection system. A combined sewer overflow is the discharge of wastewater and stormwater from a combined sewer system directly into a river, stream, or lake.
Description: The CSIAbandDistrictManhole feature class consists of points depicting eliminated or abandoned District owned/maintained manholes that were part of the collection system geometric network serving as network junctions. Manholes are a subset of the sewer infrastructure and represent those underground access structures at which two or more pipes connect.
Description: Local Sewer Pipe - The Local Sewer Pipe layer consists of lines depicting non-District owned/maintained gravity and pressure mains. A sewer pipe is a type of an underground carriage system, for transporting sewage from houses or industries to treatment or disposal. In some areas, sanitary sewers are separate sewer systems specifically for the carrying of domestic and industrial wastewater, and are operated separately and independently of storm drains, which carry the runoff of rain and other water which wash into city streets. Sewers carrying both sewage and stormwater together are called combined sewers.
