System | Description |
Under every street in town, there is an underground
world of pipes and manholes that move all of the water
that leaves the homes and businesses to the treatment
plant. These pipes are sized to handle the sewage flow
and some additional flow resulting from rain. This system
is not however designed to handle all of the rain that
falls. A separate sewer system handles the rain water.
This system is also run throughout the town.
Where topography does not allow the water to flow
to the plant via a gravity sewer system pumping stations
are installed to pump the water to a point where it
can gravity flow to the plant.
Here in New Lenox, we have 65 miles of sewer line
running under ever street in New Lenox. We also have
eleven remote pumping stations which pump the water
to a place where it can gravity flow. We also have 1700
manholes around town. These manholes serve as access
points that make it possible to get men and machines
down to inspect and repair the system.
We have television equipment that can be sent through
the sewer lines for inspection. We have hydraulic cleaning
equipment that can be sent through the sewers to clean
them or to cut roots that have entered the sewer system.
We also have flow measuring equipment that can be installed
in the manholes to measure flows in any area of town.
We have divided the community into sections and we
have established theoretical flow for each area based
on the number of homes and businesses in each area.
We then measure the flows in each area to see if we
are getting the flow we expect. We also measure the
flow in wet weather to see how much it increases. With
this information we know which areas need repairs or
inspections.
The collection system like the treatment plant must
operate 24 hours a day, 7 days per week to assure wastewater
is removed from the community. Any interruption in service
could result in homes basements being flooded with sewage.
Your crew and equipment work hard to make to make
sure neither the resident’s homes nor the nation’s waterways
are polluted.
