year and $100,000 is included in the current FY 2017-2018 budget for inflow and
infiltration elimination.
2. Though the Tennessee Valley Authority reported a total of 16.84" of precipitation was
received in the Brevard area during this quarter, there were no sewer discharge events
reported in the city.

coat of paint to the interior walls and pipe of the pump station.
o Training sessions by Wharton -Smith, Inc. and Instrulogic technicians
were provided to City Collections Division personnel, maintenance
staff and on-call employees which included the radio testing unit
interface panel, start-up of the VFD (variable frequency drive) and
starting the station pumps.
o Testing was conducted on the diversion of flow from the Neely Road
Pump Station to the new Equalization Tank during wet weather
conditions.
o Completion of punch list items continued.
o Personnel demobilized from the site and performed site restorations
as necessary.
Pump Station Temporary Start Up
o The city received a period of sustained and heavy rainfall on October
23, 2017 at which time the Gallimore Road Lift Station discharged.
During this time, the existing (old) Neely Road Pump Station reached
a high level and this was deemed a good opportunity to further test
the new pump station.
o With the approval and assistance of Wharton -Smith, Inc. and city
maintenance personnel, the old station pumps were shut down and
the new pump station pumps were placed into service. The new
pumps and technical equipment worked correctly, and as a result,
the Neely Road station did not discharge during this event, though
the rain gauge at the station registered 6.5" of precipitation.
o Heavy rain with flooding conditions occurred again on October 28,
2017 at which time Collections System and maintenance personnel
assisted an inspector with CDM Smith with the start-up of the new
lift station pumps and monitoring flows of the new lift station. This
temporary start-up of the station provided personnel and equipment
experience of the station's ability during high flow events.
