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.<\/SPAN><\/P> Diameter, install date, and material type are three key attributes maintained for this feature.<\/SPAN><\/P> If the user is working directly with the source data, they are cautioned to exclude all features wihere 'End_Date' is null. Abandoned watermains are included in data. For Cityworks and Map-it users abandoned pipes are not shown.<\/SPAN><\/P> Generally, the Material2 field lists the approriate AWWA specification as follows:<\/SPAN><\/P> C900 - PVC pipe that is <= 300mm in diameter<\/SPAN><\/P> C901 - Polyethylene pipe that is <= 75mm in diameter<\/SPAN><\/P> C903 - Polyethylene-Aluminum pipe (ie. Kitec)<\/SPAN><\/P> C904 - Cross-Linked Polyethylene Pipe (PEX)<\/SPAN><\/P> C905 - PVC pipe that is >= 350mm in diameter<\/SPAN><\/P> C906 - Polyethylene pipe that is >= 100mm in diameter<\/SPAN><\/P> C909 - PVCO pipe (molecularly oriented PVC pipe)<\/SPAN><\/P> PVC-160 - PVC pipe pressure class 160<\/SPAN><\/P> PVC-200 - PVC pipe pressure class 200<\/SPAN><\/P> <\/P>
