TO: Thomas G. Bradford, Village Manager
FROM: Thomas C. Hall, Water System Manager AO
DATE: November 16, 1995
SUBJECT: Cleaning of Raw Water Pipeline
Recent inspection of our raw water pipeline between Well No. 7 and Old Dixie
Highway has revealed a substantial build up of iron bacteria and sludge on the walls
of the pipe. This build up has accumulated since our last cleaning in 1989. Although
not as bad as last time, there is enough build up to cause a reduction in flow capacity
from wells seven and eight. This restriction is reducing our ability to maintain full
capacity from these wells and needs to be corrected as soon as possible.
In light of this need, I have obtained a proposal from Professional Piping
Services, Inc. of Land 0' Lakes, Florida in the amount of $7,920.00. This is the same
company which performed this work for us in 1989 and is the only Florida based firm
providing these services.
We are seeking Village Council authorization to expend these funds for this
work and would appreciate this matter being placed on the Village Council Agenda of
December 14, 1995 for approval.
Funding will be provided by the Water Enterprise Fund, Operating and
Maintenance account having an FY '96 Account balance of $46,573.00.
Upon approval, a purchase order will be issued and the Contractor has indicated
work will commence the week of December 18th.
