Originator	Metropolitan Council
Title	Abandoned Sewer Interceptors
Abstract	This layer contains data for those parts of the sewer interceptor system in the Twin Cities metropolitan area that have been removed from service (but not removed from the ground) The interceptor system provides the link from community sewer systems to the wastewater treatment facilities in the seven county metropolitan area.
Purpose	To provide a digital inventory of Metropolitan Council, Environmental Services division abandoned pipelines.

Section 2	Data Quality Information	Top of full metadata	Top of page
Attribute Accuracy
Logical Consistency	The dataset is topologically 'clean'.
Completeness	Between 1970 (formation of Sewer Board) and 1990 (formation of ES GIS) several interceptors were abandoned or reconveyed and were not included in the original GIS inventory. This dataset is incomplete and should not be used as a definative system.
Horizontal Positional Accuracy	The positional accuracy of the dataset has not been tested under the National Standards for Spatial Data Accuracy. The positional accuracy of the dataset is estimated to be 20 ft.
Lineage	This dataset was derived from as-built plan drawings. The data were transferred to ETAK street base files and later converted to match a 1992 (?) Minnesota Department of Transportation street base. The Metropolitan Council is in the process of developing parallel data using GPS locations for more accurate positioning.
