Wastewater infrastructure data for the City of South Burlington Vermont. This includes wastewater pipe and structure (e.g. manhole) information. It also provides information on service districts (i.e. which treatment facility wastewater flows to) and sewersheds by pump station (i.e. the areas that drain to each pump station). Finally, information used by City staff related to cleaning zones for pipe maintenance is also included in this data.<div><br /></div><div><b>Layers</b></div><div><u>Sewer Manhole</u> - This is a layer of all wastewater manholes. May include some other buried structures.</div><div><ul><li>ObjectID - Unique ID assigned by software</li><li>SBManholeID - Unique ID assigned by city staff. These typically begin wtih SMH (Sewer Man Hole) and a 4 digit number.</li><li>Location - A general description of where the structure is located (i.e. in a road, greenbelt, parking lot, sidewalk, etc).</li><li>AccessDiamIn - The diameter of the manhole access measured in inches.</li><li>Material_Riser - The material that the manhole riser is constructed out of (e.g. precast concrete, brick, etc).</li><li>Material_Chimney - The material that the manhole chimney (typically the top section) is constructed out of (e.g. precast concrete, brick, etc)<img alt='Sewer Basics: Parts of a Manhole' src='&' width='397&name=manhole.jpg' width='397&name=manhole.jpg' width='397&name=manhole.jpg' /></li><li>Material_Cone - The material that the manhole cone is constructed out of (e.g. precast concrete, brick, etc). This is the manhole section that "necks down" the diameter of the structure between the riser and the chimney.</li><li>Material_Barrel - The material that the manhole barrel is constructed out of (e.g. precast concrete, brick, etc). This is the manhole section that typically sits on the base.</li><li>Material_Bench - The material that the manhole bench is constructed out of (e.g. precast concrete, brick, etc). This is the bottom section of the manhole where the invert or channel is located.</li><li>SewerShed - The sewershed in which the manhole is located. This is based on which treatment facility wastewater flowing through the structure ultimately leads to. </li><li>PumpStaShed - Which pump station sewershed does wastewater flow to. Each pump station is given a unique ID and those are listed here. If it goes from one pump station into another both should be listed.</li><li>Access - ?</li><li>Ladder - Is there a ladder leading down into the manhole.</li><li>InvertDepth_In - Field measurement from the rim to the bottom of the invert. This is measured in inches.</li><li>RoadName - The road where the manhole is located. If not in a road, the nearest road is listed.</li><li>Elevation_Invert - The elevation of the manhole invert. This is either taken from as-built plans or measured with a GPS with sufficient accuracy.</li><li>Elevation_Rim - The elevation of the manhole rim or cover. This is either taken from as-built plans or measured with a GPS with sufficient accuracy.</li><li>InstallYear - The year that the manhole was installed. </li><li>Source1 - Where did the information included in the fields come from? As built plans? Field inspection? Other?</li><li>Source2 - Was a second source of information used to fill in the fields? If so, identify it in this field. </li><li>Comments - Any comments.</li><li>created_user - The GIS user that created the point.</li><li>created_date - The date on which the point was created.</li><li>last_edited_user - The GIS user that last edited the point.</li><li>last_edited_date - The date when the point was last updated.</li><li>GlobalID - Unique ID assigned by software.</li><li>Ownership - The entity that owns the manhole and is responsible for maintenance. If on private property indicate "private". This does not require the private property owner's name.</li></ul><div><u>Network Structure</u> - This is a layer of wastewater pump stations, diversion structures, storage tanks, and treatment facilities. Manholes do not go in this layer.</div></div><div><ul><li>OBJECTID - Unique ID assigned by software</li><li>FacilityID - Unique ID assigned by city staff. </li><li>Name - Common name used by staff to refer to the infrastructure.</li><li>PointType - Type of infrastructure: Pump Station, Storage Basin, Treatment Plant, Diversion Chamber, or other.</li><li>LocationDescrip - A general description of where to find the infrastructure.</li><li>SewerShed - Which sewershed is the infrastructure located in. This refers to which treatment plant the wastewater flowing through the infrastructure ultimately flows to.</li><li>Ownership - Is the infrastructure owned by a private entity or a public entity (generally the City of South Burlington).</li><li>SCADA - Does the infrastructure have SCADA? Yes / No</li><li>Generator - Does the infrastructure have a generator? Yes / No</li><li>InstallYear - Year that the infrastructure was installed. </li><li>Elevation - Not used, but could be defined and utilized.</li><li>WaterType - Type of water in the infrastructure. This is only used for wastewater so all are "Sewage". Not a useful field at this time.</li><li>Source - Where did information about the infrastructure come from? What is the data source?</li><li>Description - A written description of the infrastructure. </li><li>GlobalID - Unique ID assigned by software.</li></ul><div><u>Sewer Lines</u> - This is a layer of all wastewater pipe.
