This analysis shall be included in the Engineer’s Report. c. Treatment Works Approval Forms; d. Specifications for the Proposed Sanitary Sewer Facilities signed and sealed by a licensed professional engineer. 2. All on-site sanitary sewerage facilities upstream of the proposed connection to existing manhole on Bakely Terrace including the proposed pump station, gravity sewer mains, manholes, and force main shall be privately owned and operated. 3. A licensed sanitary sewerage system operator will be required for this system. This comment is to be acknowledged and the information for the licensed operator will be required prior to issuance of any certificates of occupancy. 4. Sanitary sewer gravity mains, laterals and force mains shall be constructed at least three feet below proposed grade elevation. 5. All proposed sanitary sewer mains and water distribution mains must comply with the minimum separation requirements set forth in N.J.A.C. 7:14A-23.6 and N.J.A.C. 7:10-11.10. Sewer mains must be separated from water mains by a horizontal distance of at least 10 feet. If the horizontal distance is not obtainable, the sewer must be located at least 18 inches below the bottom of the water main pipe. When separation cannot be maintained, the sewer main shall be either concrete encased or constructed of ductile-iron pipe in accordance with the aforementioned regulations. Off-Site Sanitary Sewer Comments 1. Provide a key/location map for the existing downstream sanitary sewer proposed to be connected to. 2. The connection of the proposed force main is to be shown to EX-SANMH 1 on Bakely Terrace. In addition, manhole EX-SANMH 1 is to be replaced. 3. Replace existing manholes at all locations along Marie Terrace, Schmitt Road, and Marmon Terrace where sewer main replacement is proposed. 4. All existing sanitary sewer

-SANMH 1 is to be replaced. 3. Replace existing manholes at all locations along Marie Terrace, Schmitt Road, and Marmon Terrace where sewer main replacement is proposed. 4. All existing sanitary sewer laterals should be identified for replacement wherever sewer main replacement is proposed. The laterals shall be replaced from the cleanout to the new sewer main.

The Applicant shall provide supplemental survey information showing existing utilities and any crossings that may be exposed during construction of the proposed sewer and manhole replacements. 6. The Applicant provided a spreadsheet with the projected off-site sewer demands based on the number of bedrooms for each residential dwelling. The flows calculated from the spreadsheet shall be utilized as part of the conveyance capacity study within the engineer’s report. The Applicant shall also include the sanitary sewer pipe capacity calculations in the evaluation. All capacity and flows are to be represented in gallons per day (GPD). 7. The Applicant will be responsible for ensuring compliance with Section 20-1 of the Township of West Orange Code. Specifically, Section 20-1.5f.5, indicates that any road opening must be backfilled with clean dense graded aggregate. Notes should be added to the plans indicating the same.
