The Laboratory
The Monitors

The City of Buffalo Owns, Operates, and Maintains a Municipal Water
Treatment Facility under EPA and KDHE regulations.  Our plant also relies on
the expert guidance of the Kansas Rural Water Association.  On an average
summer day, we produce 100,000 gallons of potable water.  In addition to
supplying residents of Buffalo, we currently serve two rural water districts.  The
operation consists of two raw water pumps, two high service pumps, a 100 foot
storage stand pipe, and wireless telemetry system.  The telemetry system is
made up of three Motorola radios and computers which turn pumps on and off
depending on water levels and demand.

The Treatment

Raw water is pumped to the plant basement where it is metered and combined
with three chemicals before continuing outside to the clarifier.  Each chemical is
injected with a precision metering pump based on daily lab results taken in the
plant lab every morning, 365 days a year.  The first chemical is blended
polymer, which combines with dirt in the raw water to settle out in the bottom of
the clarifier.  The second chemical is Potassium Permanganate, which helps
control taste and odor.  The third chemical is Sodium Hypo chlorite, which acts
as a Pre chlorine disinfectant prior to entering the clarifier.  This mixture then
travels into a flash mixer attached to the clarifier wall.  This step rapidly mixes
all chemicals with the water.  This mixture then enters the clarifier center cone
at the base more than 14 feet underground at a rate of 105 gallons per minute.
 Gravity then goes to work pulling the combined dirt and polymer, also know as
floc, to the bottom of the clarifier to be discharged by an automatic blow down
system.  The clean water remains at the top where it passes through weep
holes to regulate flow back into the plant and into the Final Filters.  These
filters contain several layers and types of media which attract remaining
particles to lower turbidity.  Each filter effluent turbidity is individually monitored
and recorded 24 hours a day, 7 days a week.  The water is then injected again
with Sodium Hypo chlorite for Post disinfection before entering a 30,000 gallon
underground storage tank also known as the Clear well.  From the Clear well,
potable water is pumped to the tower for Distribution.

The Requirements

Each day, 4 basic tests are performed at 5 steps of the treatment process, to
maintain proper disinfection, turbidity, and ph level.  A distribution chlorine
residual must be taken daily in the city to insure proper disinfection at the
customers home.  KDHE laboratories receive a weekly sample from customers
homes that is tested for the presence of coliform bacteria.  Each week, 4 tests
are conducted on finished water to monitor Hardness, Alkalinity, Manganese,
and Iron levels.  One time per month, samples are sent to KDHE labs for
Trihalomethane and  Halo acetic Acid monitoring.  All levels must be within EPA
and KDHE requirements.  All records of these tests must be maintained and
available upon demand for 10 years.
