RE: 660 Great Pond Road—Sewer Service Repair
Dear Ms. Hughes:
As you are aware, the Board of Health has issued an Order to Correct to the Rolling Ridge
Methodist Conference Center. The following is a narrative description of the conditions and scope
of work for the project:
The sewerage from the facility flows to a tank and is pumped to a manhole near Great Pond
Road. Discharge from this manhole flows into the Town sewer system. It is my understanding that
the existing force main has blockages and/or was not installed as designed. As a result, the pumps
are continuously running at time and unable to pass the required flow.
The applicant has hired a firm to install a new two inch force main from a point in the
existing line near the parking facility to Great Pond Road. This project will require work within 100
feet of the wetlands. The wetlands had Norse Environmental Services delineate the wetlands and
Findeisen Survey and Design LLC located the wetland flags and existing treeline.
The scope of work includes installing erosion control as required, digging a narrow trench,
installing a two inch sewer line and backfilling the trench. Since the site consists mainly of open
fields, no tree removal is anticipated and no work will take place within 25 feet of any wetlands. The
work within the buffer zone should be completed within a few days. The only impact to any
wetland resource area is a minor disruption within the 100-feet buffer zone caused by the trenching
for the sewer pipe.
Please let me know if you require any additional information or clarification of any of the
information presented above.
Yours truly,
DK ENGINEERING ASSOCIATES,INC.
