1. Approval of Minutes:
Minutes from January 31, 2017 were approved. Motion to approve by Mr. Howe, seconded
by Ms. Hunter.
2. Member Comments / Concerns: None
a. Modifications to Agenda – None
3. GHD Design Recommendations for Ellis Hollow Tank and Main:
Mr. Weber explained that the contract with GHD was expanded to look at design
considerations to the water system associated with the Maplewood Development and
additional impacts to the Town’s water system. The analysis has indicated that the water main
from the tank to the control building will need to be a 12” diameter to meet the volume
demands under peak/fire flow conditions. Also, the replacement/upgrade of the 6” line on Pine
Tree Road to an 8” line should be completed, as it is a contributing factor in the high
frequency of breaks in the Common Lands area.
4. Discussion on CIP Adjustments/Modifications:
Mr. Weber stated that CIP projects will be shifted by two years. In addition to the Ellis Hollow
tank and water main projects in the East Hill area, the upgrade of the water main on Pine
Tree Road will be added for construction once the Ellis Hollow Tank and main are completed.
Additionally, we are looking at replacing the water main on Winthrop Drive due to increasing
breaks in the area, and this will be completed prior to the road improvements (currently
identified for work in 2023) being completed. Additional road improvements will be advanced
or added to the CIP due to deterioration from this winter season (Chase Lane and Lagrange
Ct.). Modifications will be made to the CIP plan and will be presented for consideration at the
next PW Committee meeting. There were discussions concerning the differences in
construction costs and how the unique nature of each road ties into the projects.
5. Larisa Lane Sewer request:
Mr. Weber summarized the history of this request, the discussion from the September 20,
2016 Committee meeting, and reported that three alternatives had been presented from the
applicant’s engineer. Mr. Simkin presented the options and the costs associated with each.
Option 1 included an insulated pipe due to the lack of cover. Option 2 included the rework
and extension of sewer on Larisa Lane. Option 3 included the new installation up the future
Schickel Drive. Due to the insulation requirements of Option 1 and the costs of Option 2,
Option 3 was determined to be acceptable to the committee.
6. Sanitary Sewer Meter Pit Discussion:
Based on discussions at the SJC and contacts made by the WWTP operators to Town staff
the need for and costs of repair to the pits at the City/Town line were discussed. Items
discussed included; control and monitoring of infiltration/inflow, annual billing, City/Town
agreement discussions, maintenance requirements and costs, and the ultimate use of the
flow data. Town staff can complete the work to upgrade the current meters but the cost
associated with the work will be dependent upon the ultimate use of the data. Discussion with
the other members of the SJC will continue.
7. Project Status:
Sapsucker and Christopher Circle Water Main Replacements –The projects are waiting
for the contracts to be signed. The Sapsucker work will begin once the contracts have been
signed and the Christopher project has a request to delay the start until June.
Ellis Hollow Tank Design/Approval Process – Mr. Weber reported the scope of services for
the design and construction of the tank and main are being worked on. Current schedule is to
be before the Planning Board on 4/18 for site plan approval, Town Board on 4/24 and 5/8 for
public hearing of the Public Interest Order.
South/West Hill Water Study – Mr. Weber reported that the Scope of Services has been
completed and will be sent to the consultant (GHD) for consideration and a proposal. The
current Town budget included $80,000 for this work.
The meeting was adjourned at 10:34 a.m.
Our next meeting will be on 4/16/17 at 9:00 a.m.
