Water Department Memo
To: Public Safety, Utilities & Public Works Committee
Town Administrator Lancaster
From: Jeff Boles, Water Superintendent
Reuben Bergsten, Utilities Director
Date: October 13, 2016
RE: Membrane Replacement at Marys Lake Water Plant - Unbudgeted
Objective:
To replace 174 membrane modules that qualify for prorated warranty replacement
based on fiber breakage numbers per module and to replace the remaining 150 first
stage modules in order for all membrane trains to contain the same module versions
and operate from the same programming parameters.
Present Situation:
During the installation of the membranes there was initially a large amount of fouling,
plugging on the fibers which required an intensive cleaning of the modules. GE
representatives came on site to instruct and assist in this initial cleaning of the fibers.
Due mainly to the initial cleaning process, we have experienced a higher than normal
fiber breakage rate. Of the existing 308 first stage membrane modules, 174 have had
enough fiber breakage to qualify for replacement through the prorated 10-year warranty
that was added to the membrane procurement contract. $160,000 was budgeted in
2016 for replacement of the 174 modules with the high fiber breakage.
Proposal:
Due to a 5-month product delivery lead time and the programming modifications that
need to be made for the new modules, we request to amend the budget by $120,000 to
include the purchase of the additional 150 modules, freight and U.S Customs duty fees
so that all membranes will arrive together and only one programming site visit would be
necessary to setup the new operational parameters.
Advantages:
All first stage membranes will be replaced, utilizing new module and fiber design that
has a 45% increase in fiber thickness which is more robust and requires less fiber
maintenance than the previous versions. When the Enterprise Fund Large Expense
Policy was started in 2013 the estimated module replacement cost was at
$2,200/module. Since then, the module prices have dropped significantly to
$838.94/module and $538.32/module for the modules under the prorated warranty. The
3
total cost proposal for replacement of all three membrane trains is $263,964. Based on
this cost reduction there are currently adequate funds that have been set aside in the
Enterprise Large Expense Fund for the total replacement of the membrane modules.
Disadvantages:
Since the new modules operate at a higher pressure, the modules within each train
must be the same version for programming operations; however, by replacing all three
first stage trains, the operational programming would only need to be modified once and
will remain consistent.
Action Recommended:
Town Board approval to amend the 2016 Budget to replace all first stage membranes.
Budget:
Account Number: 503-6200-530.26-40
Account Name: Purification Equipment
Amount Requested: $120,000
Level of Public Interest
Low: Repair, replacement and system maintenance items do not typically generate
large public interest.
Recommended Motion:
I recommend approval to amend the Water Department budget by an increase of
$120,000 for the replacement membrane module purchase, to be included as an
consent item at the October 25, 2016, Town Board meeting.

Water Department Report
To: Public Safety, Utilities & Public Works Committee
Town Administrator Lancaster
From: Jeff Boles, Water Superintendent
Date: October 13, 2016
RE: Axminister Lane Water Line Installation
Objective:
To inform the PUP Committee of the Axminister Lane water line replacement project.
Present Situation:
The existing 2” galvanized water main in Axminister Lane was replaced with an 8”
ductile iron pipe prior to the Public Works street improvement project on Axminister
Lane. The project was very successful and completed on time and came in at a total
project cost of $125,494.94.
The project cost breakdown summary is as follows:
Labor Costs: $17,696.78
Materials Costs: $57,510.63
Internal Equipment Costs: $20,084.75
Excavator Rental Costs: $4,800.00
Compaction Testing: $1,100.00
Outside Equipment Mobilization: $1,351.46
Bedding Material: $2,287.32
Asphalt Patching: $20,664.00
A total of 1,200 feet of water main line was replaced which averaged $104.58/ft. for the
project.
