History: August 2004 - Conversion of DGN files maintained by Engineering into SDE September 1 2004 - Conversion of attributes from MS Access database maintained by Engineering into SDE May 2005 QC of convered attributes August 2005 started updating layer based on Service Agreement: DTS - Engineering : Sanitary, Storm Drainage, Road Infrastructure, Sidewalk, Survey Monumentation.

Current Info Source: The majority of sewer pipes were mapped using the 1997 aerial photography where manholes were visable in reference to paper as-built drawings. Based on the accuracy of the aerial photography and computer methods, the position of the pipe is expected to be within 1 meter of actual location over 90% of the time.
Outstanding Issues: Backlog of New Infrastructure from 2002. 1999 Infrastructure with no Attributes, Prior to 1999 Infrastructure Attributes needed QC started.
Update Frequency: CONTINUOUS

Data Fields & Domain Information

Sanitary_Pipes

Column Name Alias Data Type Comments Domain Name Default value Domain Values
OBJECTID OBJECTID NUMBER ESRI system maintained integer field used to uniquely identify rows in tables in a geodatabase. Note that OBJECTIID values change upon export or import of the data and should not be used as a primary field for searching or identifying records.
SANPIPEID Sanpipe ID NUMBER Database maintained field that permanently assigns a unique value for each record. This ID value should be the one referred to when identifying a record.
PARENTID Parent ID NUMBER Input by GIS staff. Used when an an existing sanitary pipe is split for any number of reasons. The existing record is split into 2 or more individual records. The longest single existing record retains its SANPIPEID value and no value is entered into PARENTID, however for each of the remaining shorter existing records the original SANPIPEID value is copied into the PARENTID field, their SANPIPEID values are deleted and the database generates new SANPIPEIDs for the 2 or more new shorter records. This is done so that information, such as work orders, could be linked back to the records that have new SANPIPEID values.
START_PIPE is this the first pipe in a drainage basin VARCHAR2 Input by GIS staff. Identifies if the sanitary pipe is the first pipe in a drainage basin (the highest elevation pipe in a gravity pipe flow network). Values are codes. The following uses the key 'CODE' ('DESCRIPTION').
