The
water treatment plant is located at 395 W. Jersey
Street. It is a 1 million gallon per day facility.
Construction started in the summer of 1993 and was
completed in the spring of 1995. The plant cost was
approximately 2 million dollars.
The
plant uses food grade lime to soften the water. The
addition of lime aids in the removal of calcium and
magnesium in the water. These two minerals make up the
total hardness of the water. Another chemical used in
the treatment is polymer. Polymer helps in maintaining
the lime sludge blanket within the cone so it will not
flow over the weirs and helps the settling
process.
After lime and
polymer is added in the Clari Cone, C02 is introduced for ph adjustment.
Water leaving the plant ranges between 7.5 and 8.5 ph
value. The last chemical added is sodium hypochlorite.
This is added to keep the water bacteria free after it
leaves the plant.
The plant permit is governed by the Ohio
EPA.
The water treatment laboratory is certified by
the OEPA to run ph, alkilinity, hardness, chlorine and
stability tests. Johnstown's lab has two full lab
certified personnel. All other operators are licensed by
the state of Ohio to run daily tests and plant composite
tests.
The distribution system is made up of 22.3 miles
of piping ranging in size from 2 to 12 inches. the
majority of the pipe is ductile iron pipe ( DIP ) and
polyvinyl chloride ( PVC ) pipe. The system also has 202
fire hydrants and numerous valves and continues to grow.
The newest feature to the distribution system is the one
million gallon water tower which went online in October
2002. It replaced the 250,000 gallon tower. The new
tower has increased water pressure throughout Johnstown
and now has Johnstown in compliance for storage meeting
the OEPS's guidlines.
The water treatment facility
and distribution system is under the direction of the
utilities director Jack Liggett. Any questions about the
system or the plant should be directed to the utilities
