A meeting of the Fayetteville Water and Sewer Committee is planned fo anu�lry 10, 2006, at
5:30 PM, Room 326, Fayetteville City Hall. Proposed topics include:
1. Approval of the Minutes of November 29 Water/Sewer Committee Meeting.
2. WSIP Update.
a. Subproject WL-5, Force Mains from Hamestring Lift Station to West Side WWTP, was
awarded to Garvey Construction January 3, 2006. Work is scheduled to begin the second week
of February.
b. Subproject WL-1 and 3, Gravity Lines from Old Wire Road to Gregg Avenue, and
Gravity Lines from Porter Road to Hamestring Lift Station, combined as one contract, will open
bids on January 24, 2006. The Contract provides for the construction of approximately 30,831
linear feet of gravity sewer main, mostly 21-inch through 36-inch diameter, 116 new manholes,
removal and or abandonment of 114 manholes, 632 linear feet of 48-inch bore and jack, 503
linear feet of 42-inch bore and jack, 880 linear feet of 36-inch bore and jack, creek crossings and
related work, along Hamestring Creek and Mud Creek.
c. Subproject WL-4, Gravity Lines and Force Main from Gregg Avenue Lift Station to
Hamestring Lift Station, will open bids on January 31, 2006. The Contract provides for the
construction of approximately 24,751 linear feet of gravity sewer main, 8-inch through 48-inch
diameter, mostly 48-inch diameter, 3,876 linear feet of 30-inch diameter force main, 69 new 6-foot
diameter manholes and 5 new 4-foot diameter manholes. Although mostly installed by open cut,
with some areas of rock excavation, other methods of pipe installation include 913 linear feet of
72-inch encasement by pipe jacked tunneling, 789 linear feet of 68-inch encasement by open cut
and dry auger bore and jacking, and 486 linear feet of 48-inch encasement by dry auger bore and
jacking. Additional items include erosion control, tree removal/protection, creek, road, and
highway crossings and related work, along Clabber Creek.
d. Project Staffing. A draft budget is attached identifying anticipated staffing needs for
WSIP management. The plan includes three staff members (project manager, inspector,
secretary) and two vehicles, all to be paid for out of the project. The positions are intended as
contract employees who will receive basic City benefits excluding retirement. Compensation is
based on existing City job descriptions, with starting salaries within the full range of the pay scale
for that position depending upon qualifications. The contract will include a 12% deferred
compensation agreement, to be paid in full upon completion of the contract. The contract term
will end 12 months after the date of substantial completion of the West Side WWTP. Cross
Gunter will develop these unique employee contracts.
This proposal will cost approximately $800,000 over three years, $700,000 below the
budgeted cost of$1.5 million.
e. Backup Power Generator Alternatives. Staff is evaluating the proposal from Power
Secure for purchase of the generators required for the West Side WWTP and the Hamestring Lift

Station. Using the power generator installed at the Noland WWTP has reduced our electrical
costs by $16,000 per month for 2006.
f. Easement Status Update. Verbal update on the status of easement negotiations.
3. West Side (Hamestring Basin) Interim Sewer Collection System Evaluation. The final
report has is attached. To summarize the evaluation, the City has dry weather capacity for 1,683
additional single family dwelling units. Growth in the area has peaked in the last five years at 374
units in one year. Assuming this peak is the rate of growth in the future, there is sufficient
capacity for 8.5 years of growth. The report identifies a range of alternatives to allow maximum
flexibility in the event the development pace greatly exceeds that in the past. We do not
anticipate having to execute any of these plans. Staff will continue to track the number of new
active accounts, continue the current sewer flow monitoring, and perform quarterly lift station
calibrations in order to ensure we are prepared to meet any changing circumstances that may
arise.
A development rate of 800 units per year, for a total of 2400 units, would require one of the
construction alternatives be installed. Construction Alternative B in the Interim Evaluation Report
is the most feasible alternative, with an estimated cost of $2,428,000. This alternative then would
cost an estimated $1,000 per unit. Staff recommends each developer contributing sewer flows in
the Hamestring sewer basin provide a security of$1,000 per unit to fund this construction, in the
event it is required. If the pace of development is such that construction of an interim solution is
not required, the security would be returned to the developer that provides it.
4. Sanitary Sewer Rehabilitation Project Update.
a. Basin 1-5, 18 & 19 Sewer Rehabilitation Construction. Bid opening is scheduled for
January 19, 2006.
b. Farmington Area. Manhole rehabilitation is complete. Final design is underway for
line work, in accordance with the arbitration agreement.
c. Insituform Term Contract Renewal. In 2002 Fayetteville solicited sealed bids for
cured-in-place sewer lining services, with Insituform submitting the successful bid proposal.
Under the terms of the agreement, these sewer rehabilitation services can be renewed annually
for up to five years. To date, there have been no price increases in the cost from the 2002 bid,
although there is a provision in the contract for annual adjustments. For the 2006 term, Insituform
is requesting a price increase of approximately 10% per unit. At the adjusted prices, we can line
sewer 8" sewer lines, creating effectively a new pipe, for$39.50 per foot, less than half the cost of
dig and replace in most cases. Insituform is a product that allows sewer main replacement via
lining with minimal excavation and using in-house engineering. The resulting cost is less than half
of contracted work, but can only be used in specific applications. These services are used on an
as-needed basis as part of the ongoing sanitary sewer rehabilitation program.
5. Beaver Water District Negotiations. Negotiations are continuing between staff and BWD
relating to improving the watershed protection.
6. Elkins Contract Update. The contract is approved and signed by both parties. The new
meter has been installed and calibrated.
7. Farmington Contract Update. Staff is evaluating impacts of Farmington flows in the
Fayetteville system downstream from where Farmington ties in.
8. Scheduling the Next Water/Sewer Committee Meeting. Staff recommends the next W/S
Committee meeting be scheduled for Tuesday, February 2, 2006 at 5:30 in room 326.
