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.

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.
