Melbourne’s drinking water —
not too hard, not too soft
Water hardness
is usually
observed by its
ability to form
scale and make
suds with soaps
and detergents.
The operating
instructions for
some domestic
applicances,
particularly
dishwashing machines,
refer to
water hardness.
Hardness in
water is defined as the sum of the calcium and magnesium
concentrations, expressed as calcium carbonate.
The hardness of the water varies with the amounts
of these salts.
The hardness of the water produced by the City of
Melbourne averages approximately 85 milligrams per
liter (mg/L) or five grains per gallon (gpg).
The U.S. Geological Survey has developed a generalized
water hardness scale that rates soft water as
between 0 and 60 mg/L (0-3.5 gpg), moderately hard
as between 61 and 120 mg/L (3.6 - 7 gpg), hard water
as being between 121 and 180 mg/L (7.1 - 10.5 gpg),
and very hard water as being above 180 mg/L. (>10.5
gpg). Milligrams per liter is converted to grains per gallon
by multiplying mg/L by 0.06.
Home water softeners, when used in conjunction
with City water, can cause the water to become too
soft. This can cause corrosion of the plumbing, allowing
copper to enter the home’s water supply.
As a result of the leaching of copper pipes in the
residence, sinks and bathtubs would begin to develop
a green or blue coloration.
Water delivered by Melbourne contains trace copper
amounts that are below the level determined as safe
by the federal Environmental Protection Agency.

Monthly Report
PW & Utilities department show
care through United Way giving
The annual United Way campaign has been completed
and the City’s Public Works & Utilities Department
contributed $10,750 that will used to help fund 87 local
health and human services programs.
While the employees in the department are 25 percent
of the total 935 City employees, they contributed
30 percent of the City’s overall total contribution of
$36,146.
“Public Works & Utilities did exceptionally well this
year,” said Sue Fallon, the City’s United Way campaign
manager.
City gets ready for the holidays
The Facilities Maintenance Division takes care of preparing
City Hall for the holiday season. Don DeLoach,
inside the bucket, is shown hanging the large Christmas
wreath at City Hall. A sailboat, which is part of the
City’s logo, has been placed in lights in the center of
the wreath. Greg Valenti observes from the ground.
Other decorations include lights on the trees in front
of City Hall. The division has also hung a large wreath
at the Melbourne Auditorium and holiday banners in
downtown Melbourne.

New well at RO plant to provide backup to existing wells
Design has
recently begun
for a backup well
at the Joe Mullins
Reverse Osmosis
Treatment Plant.
When construction
is completed,
the new well will
provide a more
flexible and reliable
source of groundwater.
In 2002, the City
identified the need
to construct an
additional Floridan
Aquifer production
well as a backup
due to the occasional extreme water quality issues in
Production Well #3A.
Water Production Superintendent Fred Davis in front of Well #2.
In addition, the new well can be used to backup any
of the other three wells in case of power outages, mechanical
problems or regular preventive maintenance,
and if the backup generator fails.
“This was a problem during the 2004 hurricane
season,” said Water Production Superintendent Fred
Davis. “We lost service on one of the generators during
Hurricane Frances
and we could only
use one well.”
The new well will
also be a first step
toward an expanded
wellfield needed to
support the potential
future expansion of
the RO facility.
L.S. Sims & Associates,
a hydrogeological
firm, is providing
the design, which
should be completed
in February. Construction
of the well
should be completed
by early summer.
According to Larry Sims, the new well will descend
700 feet underground. “Like the others, the minimum
flow will be 2,500 gallons per minute and it will be a
16-inch well with piping from the well to the RO Plant,”
Sims said.
The construction estimate for the well is between
$350,000 - $500,000. The pump house and control
system is expected to add another $150,000 to the
construction cost.
