Sewer System Comments – Mariusz Jedrychowski & Joe Hausmann, Wright Pierce
Memorandum. dated 3/18/2022
1. Sewer Calculation notes say 21 units with Existing house being 22nd unit.
Response: This was corrected to exclude the existing house, but include (22) twenty-two units as
the Calculations depict. Bold note on Summation of Proposed Sewage Flow spreadsheet has
been removed.
2. The calculations utilize an average daily flow of 400 gpd per 3-bedroom unit.
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).
This office acknowledges Town of Montville should verify this flow with past developments to
ensure consistency with typical flow assumptions.
3. Discrepancy between 6” or 8” Dia. Size Sanitary Sewer in street.

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):

· The sewer line from MH on the site to the public sewer in the street labeled as 6”
Response: Conveyance Calculation was provided for said 6” Lateral. To be included in the revised
Sanitary Sewer Report.
· The pipe material for the 2” force main does not appear to be labeled.
Response: 2ӯ 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: Acknowledged.
· It is recommended that the lift stations and the private grinder pumps have some form of
emergency backup power.
Response: Individual grinder pumps have been eliminated for each unit; a note was added to the
plan callout stating the pump station model WH483/ WR483 Triplex with Emergency Backup
shall be provided.
Water System Comments – Mariusz Jedrychowski & Joe Hausmann, Wright Pierce
Memorandum. dated 3/18/2022
· It is understood that the plan is to have individual water meters at each of the two new 22
condominiums, instead of a single main meter.
Response: Each block of Condominiums, one of 9 (North Side) one of 13 (South Side) make up
the total of 22 Condo’s; which will each have its own separate water meter for each individual
unit for a total of 22 total meters.
· Montville’s WPCA ownership of the public water line ends at the proposed new tap at the
street.
Response: This has been depicted in Plan.

· Provide the minimum separation distance of 10’ horizontally between the water line and
sanitary lines.
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.
Response: Call out was added to Plan on Sheet C 3.2 “New 12” X 6” Tap for Fire Service line.
· The 6” fire service line also needs to have valving shown.
Response: Valving was added to 6” Fire Service Line.
· Suggest looping the water lines or installing flushing devices on the dead-ends.
Response: A closed loop system has been designed with Blow Off Hydrants at the terminal end
of each building row. Isolation valves have been added for further zone control.
· Please confirm if sprinklers will be required in the building for fire protection. If so, please show
those connections and confirm that adequate fire flows exist with sprinklers and hydrant active.
Response: Sprinkler’s are not required for this Residential condominium complex. The units shall
be constructed in groups of two (2) with firewall separation.
Town of Montville – Water Pollution Control Authority Memorandum, dated 3/15/2022. 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

Response: Basements have been eliminated, thus negating the need for individual grinder
pumps. All units have been designed to discharge into a gravity line which leads to the two lift
pumps at the eastern end of the parking area.
· All maintenance of sewer and associated equipment is the requirement of property owner.
Response: Maintenance of sewer and associated equipment is the responsibility of the property
owner has been acknowledged and directed to the owner.
· Emergency power is recommended to ensure functioning of the systems during storm events
due to proposed storage volumes in sewer equipment.
Response: The e-ONE pump station units are to be equipped with emergency back up power.
Note was added to the plan set.
· C-3.2 drawing indicates an erroneous notation for a pump station.
Response: Erroneous note has been removed.
· Lift stations located east of the two buildings do not meet depth requirements (36 inches).
Response: Inverts of the inlet pipe were lowered to 3’-6” (42”) to top of pipe.
Water
· There is an option to meter each unit (noted curb stop at each) or one meter at street.
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.
