The wastewater collection
system serves the developed area of the Village covering approximately
12 square miles with over 89 miles of sewer main, and 1,629 manholes with continuous additons through developments.
The collection system
has ten lift stations, central collection points for a service
area, throughout the Village. The wastewater flows by gravity
to a lift station; it is then pumped via force main to the service
area of the gravity interceptor, or in three cases, to another service area.
There are two pumps in
each lift station, which cycle on and off automatically. Floats,
or a level sensing system, sense the liquid level in the collection
wells and control the pumps. All lift stations are monitored
for alarm conditions by radio telemetry. Any alarm conditions
are transmitted to the master unit at the WWTF and system personnel
are notified by a telephone dialer system.
