Description: There are no attributes currently maintained for tanks - Dec 2013Location is geographically accurate and is based on the locations of the access covers.
Description: Sanitary pipes are shown as positionally accurate as possible to their geographic locations. Gravity locations are usually determined by the manhole locations. Most sanitary pipes that operate by gravity run straight between manholes.Low pressure locations are usually determined by field ties based on locates since these pipes are typically installed by directional boring, and do not run as straight as gravity pipes between visible features. Forcemain locations are also determined by field ties.Lifecyclestatus, InstallStatus, Diameter, install date, and material type are three key attributes maintained for this feature.
Description: Watermains are shown as positionally accurate as possible to their geographic locations. Since the watermain is not visible, these locations are usually determined by features on the pipes - such as valves. For newer watermains, measurements may be obtained during construction.Diameter, install date, and material type are three key attributes maintained for this feature.If the user is working directly with the source data, they are cautioned to exclude all features where 'End_Date' is null. Abandoned watermains are included in data. For Cityworks and Map-it users abandoned pipes are not shown.Generally, the Material2 field lists the approriate AWWA specification as follows:C900 - PVC pipe that is <= 300mm in diameterC901 - Polyethylene pipe that is <= 75mm in diameterC903 - Polyethylene-Aluminum pipe (ie. Kitec)C904 - Cross-Linked Polyethylene Pipe (PEX)C905 - PVC pipe that is >= 350mm in diameterC906 - Polyethylene pipe that is >= 100mm in diameterC909 - PVCO pipe (molecularly oriented PVC pipe)PVC-160 - PVC pipe pressure class 160PVC-200 - PVC pipe pressure class 200
