Response: This flow may also be found in the CT-DPH Code Technical Standards Section IV. Design Flows, Table 4. (Although the code is for Onsite Sewage Disposal, the Design Flows shall be similar for the Sanitary Sewer System).

Size Sanitary Sewer in street. Response: Reference to “Grading, Drainage, & Utility Plan for Commercial/ Residential Complex Norwich-New London Road (CT Route 32) Montville, Connecticut Prepared for Tomashe LLC 19 The Quill Group Fuller Engineering & Land Surveying, LLC Civil Engineering, Landscape Architecture, Surveying Atlantic Consulting & Engineering, LLC Geotechnical, Structural, Mechanical, Electrical, & Plumbing Fairfield Testing Laboratories, LLC Materials Testing, Inspection, & Certifications, Special Inspections P a g e | 4 Tulsa Court Monmouth Junction, NJ 08852. By Development Solutions, LLC Dated September 19, 2014, Revised through 3/17/15”. Said drawing was used as the base and depicts the Sewer Lateral to be 6” service, but the Sanitary Main north of the San. MH (where this development will tie in) lists the Existing Sanitary Sewer as 8” Service. See Cut Out Attachment: CUT OUT ATTACHMENT Response Con’t: As a safety factor, and provided for confidence in not overwhelming the existing Sanitary Sewers’ capacity, @ 8”Ø QAllow= 0.856 cfs, @ 6”Ø, Calculated QAllow= 0.397 cfs Using the same slope and material, which are both > the proposed Q (flow) going into the System from the 22 units including Stormwater infiltration which was calculated as 0.054 cfs. Therefore, either 6” or 8” size main will suffice. This writer agrees that the Existing Sanitary Sewer service should be verified to avoid any future confusion or conflict. Note Added to Existing San. Sewer Line on Utility Plan DWG No. C-3.2. as depicted above, “EX. 8” Sewer”. 4. Sewer Calculation Peak Pumping factor is 5000 GPD / pump therefore x 2 = 10,000 GPD or 0.0155 cfs which is < 0.054 cfs Peak factor used in calculation. Response: See the Revised Report Summation of Proposed Sewage Flow (Pump Peaking Factor): Plan Review Comments – Mariusz Jedrychowski & Joe Hausmann, Wright Pierce Memorandum. dated 3/18/2022 · There is a none on Sheet C3.2 that calls out San MH Lift Station, Response: The callout has been removed.

To be included in the revised Sanitary Sewer Report. · The pipe material for the 2” force main does not appear to be labeled. Response: 2”Ø PVC label was added to the Utility Plan Sheet C3.2. e-One recommends the use of HDPE 11 pipe for force main piping. · The 6” PVC sewer coming into each of the 2 lift stations is too shallow. Response: 6” pipe invert was adjusted to be 3’-6” to the top of the pipe in lieu of to the invert. · The system is being referred to as a Low-Pressure Sewer (LPS), but this is not entirely accurate. The system has both low pressure and conventional gravity sewer elements. Response: The individual grinder pump in each unit have been eliminated and a gravity lateral is being proposed from each unit to a 6” gravity distribution sewer to the communal lift stations. This has been depicted on Plan and in Report. Conveyance Calculations have been provided for the new 4” Sanitary Laterals. · The Town of Montville WPCA should make it clear that the Sanitary Sewer System is a private system and are to be maintained privately.

Response: !0 feet has been provided between said utilities, dimension has been added to the plan set. · Please provide a fixture count or other flow analysis to confirm the sizing of the 2-inch feeder lines on the property. Response: Fixture count spreadsheet has been provided as well as a Table of Water Service Line- Sizing for a Supply System with Flush Tank. The 2” feeder line size is adequate; Total Water Fixture Units (WFU) = 224 yields 2” size line adequate up to 250 WFU. [See Attachment RE: WFU] · If the 2-inch size is confirmed, instead of a 2-inch tap that is branching into two 2-inch feed lines, it is preferred to have the tap be a 12” x 4” tap at the main, and then split the 4-inch pipe into the dual 2-inch feeder lines. Response: Since 2-inch feeder line is confirmed adequate, New 12” X 4” Tap was provided in lieu of the 12” X 2” Tap. · Call out the 12” X 6” Tap for the Fire Service main as well.

To Liz Burdick, Town Planner, From Derek Albertson, WPCA Superintendent. Sewer · Field Conditions will verify the receiving sewer main at street is 8-inch; a 6-inch line (indicated) may exceed capacity during simultaneous pumping of both proposed lift stations. Response: The line was checked with both 8” & 6” sizes, verifying that the main is adequate to receive the additional design flow from the New Condominium Complex. · Individual grinder pumps may not be required if sewer lines are placed at a greater depth The Quill Group Fuller Engineering & Land Surveying, LLC Civil Engineering, Landscape Architecture, Surveying Atlantic Consulting & Engineering, LLC Geotechnical, Structural, Mechanical, Electrical, & Plumbing Fairfield Testing Laboratories, LLC Materials Testing, Inspection, & Certifications, Special Inspections P a g e | 7 Response: Basements have been eliminated, thus negating the need for individual grinder pumps.

Response: Proposal is to meter each individual unit. · Recommend the configuration from 12-inch water supply main to 4-inch pipe then two 2-inch supply lines rather than what is depicted. Response: The above change has been incorporated into the design. Refer to Utility Plan Sheet C-3.2. · Blow off recommended for each 2-inch line Response: Blow off hydrants have been specified at the terminal ends of each building side. · Recommendation that the water supply lines be “looped” Response: Water distribution lines have been re-designed as a loop system.
