Narrative of the Maps for Town of Burnsville WWTP
Map 1—Topographic Map
This map shows the the facility location and the surrounding terrain as well as the river placement.
It also shows the direction of outfall from the facility.
Map 2—Ariel View
This map has 4 descriptive tabs that describe what can be seen from above.
1- Ariel Gravity Influent Tab with a directional arrow
2- Influent Tab with a directional arrow and line to show how it enters the facility
3- Sludge Drying Beds Tab with a location arrow
4- Outfall Tab with a line and directional arrow
Map 3—Zoomed in Ariel View of the Facility
This map has 5 descriptive tabs that describe what can be seen from above.
1- Manhole Tab with a black dot to show location
2- Influent Tab with directional arrow and line to show how it enters the facility
3- Ariel Gravity Influent Tab with a directional arrow
4- Sludge Drying Beds Tab with a location arrow
5- Effluent Tab with a line and directional arrow
Map 4—Facility Flow Diagram
This map is a detail description of the waste water treatment plant flow diagram.
From the top middle of the page it shows the
-Influent -Mechanical Bar Screen -Flow Division
From there it divides into the 2 large circles:
RIGHT circle is the Contact Stabilization .5 MGD Plant with directional arrows:
-Reaeration Zone -Clarifier -Sludge Return -Chlorine Contact
-Effluent -Digester -Waste Sludge -Sludge to Dewatering
LEFT circle is the Contact Stabilization .3 MGD Plant with directional arrows:
-Reaeration Zone -Clarifier -Sludge Return -Chlorine Contact
-Effluent -Digester -Waste Sludge -Sludge to Dewatering
From the Sludge Dewatering Press. there is an arrow showing the Sludge Compost Facility towards the bottom left
corner of the page and there is an arrow continuing from the Sludge Dewatering Press. around the left circle showing
the Sludge Pressate Return.
From the two large circles coming back together in the center there are directional arrows for the Effluent Dechlorine
that goes to the Cane River Outfall showing the Upstream and Downstream.
