The City of DeKalb's public water system is a modern,
state-of-the-art water supply that uses a combination of ion
exchange softening and iron removal filtration to produce a
reliable and safe water source to the citizens of DeKalb and
Northern Illinois University.
The source of water provided
to the residents of DeKalb comes from six deep wells, drawing
water from the Ironton-Galesville and St. Peter sandstone unit
of the Cambrian-Ordovician aquifer, and three shallow wells that
draw water from the Troy Valley Aquifer. These two
aquifers provide an excellent source of water to the City of
DeKalb which is essentially free of contaminants.
Groundwater is treated at
one of five ion exchange/iron removal Water Treatment Plants.
The treatment process produces a high quality water supply by
reducing the amount of hardness and iron in the water.
Before leaving the Treatment Plant, the groundwater is treated
with chlorine and phosphate to insure the safety of the water
supply within our distribution system. In addition,
fluoride is added to the water to promote the development of
DeKalb's water is monitored for microbial, inorganic and
organic chemicals, pesticides and herbicides and radioactive
contaminants. Over 14,000 water analyses are performed annually
on the City's drinking water for over 100 different
contaminants. We are pleased to inform you that the City
of DeKalb's drinking water meets or exceeds
Federal and State Drinking water standards.

can be costly and can waste a valuable resource.
A water leak may add an additional $500 to
$1,000 in water and sewer charges onto you
quarterly utility bill. From our
experience, 90% of the leaks in residential
plumbing systems are found at the toilet tank.
The best way to determine if you have a water
leak is to check your water meter. Most of
the current water meters in our system have a
flow indicator on the top of the meter (small
blue disc). If the blue disc is turning,
water is being used somewhere within the home.
If you notice the disc turning, but cannot
account for the water use, you may potentially
have a leak.
