C. Standard water, sewer, and repurified water notes as shown in this manual.
D. Signature block for MWSD approval of sewer and water facilities in the form to be provided by the Department, See Figure 5. Indicate which facilities are included on construction drawings.
E. Benchmark description and latest elevation. (NAVD88 Datum) F. Basis of bearings (NAD83 Datum)
G. Name, address, phone number, and contact person of the engineering firm preparing the plans.
H. Name, address, phone number, and contact person of the property owner or developer.
I. Index of sheets.
J. Quantity estimates and construction notes may appear on the title sheet. Construction notes for water, sewer, and repurified water shall not be mixed together and shall appear under separate headings. Different number series shall be used for each type of facility.
K. TN 1-Call notification block (Figure 6).
L. Street sections showing street widths to right-of-way and location of sidewalks.
2.3.2 Plan and Profile Sheets
All plan and profile sheets shall include the following information:
A. Scale. Horizontal scale shall be 1” = 50’ and be clearly indicated. The vertical scale shall be 1” = 5’ and be clearly indicated.
B. North arrow.
C. At least two (2) separate points of the utility system must be tied into the TN State Plane Coordinate System (NAD83).
D. Plan and profile shall be on the same sheet for all sewer mainlines. Sewer lateral profiles may be required on larger non-single family unit developments.
E. Existing water, sewer, repurified water and storm sewer facilities adjacent to the proposed development must be shown. Size and material of these facilities must be indicated.
F. Proposed and existing easements to be dedicated to the Department for sewer, water, repurified water and storm sewer facilities must be shown on the plan.
G. Proposed building or dwelling unit pad elevations must be shown.
H. Storm drain alignment shall be indicated in the plan view and all crossings of water, sewer, or repurified water facilities and the storm drain shall be shown in the storm drain profile. Where water lines cross over the storm drains the top of the storm drain and the bottom of the water line must be shown, along with the proposed depth of cover.
I. Provisions and requirements of Sections 3, 4, and 5 shall be adhered to in designing the various facilities.
2.3.3 Digital Submission Requirements
All engineers preparing construction drawings to submit to the Department for plan check purposes will be required to submit a digital graphics file containing the boundary
information, street centerline, curb and gutter, right-of-way, lot/parcel line, easements, domestic water, sewer, and repurified water facilities included in the plan.

Boundary Data Street Centerline Curb and Gutter Lines Right-of-Way Lines
Lot/Parcel Lines Easement Lines
Building/Structure Footprints Domestic Water Mains
Domestic Water Service laterals
Domestic Water Appurtenances (i.e., Valves, Fire Hydrants, Meters)*
Sanitary Sewer Mains Sanitary Sewer Laterals

Data Accuracy and Coordinate System
The accuracy of data submitted in accordance with these specifications will be consistent with data converted directly from COGO and may be used for computational purposes during the plan check and construction phase of the submitted project. The coordinate system of data shall be the TN State Place Coordinate System (NAD 83). File Formats and Media Requirements Digital files are acceptable in either an Autocad drawing file (DWG) format or a drawing exchange file (DXF) format. Digital files should be submitted on a Windows formatted CD.
Checking of Digital Data
The digital data will be checked for the following:
1. Correct layering
2. Verification that annotated and calculated data are consistent 3. Verification that digital and hard copy plans are consistent 4. Verification of correct coordinate system
5. Verification of a continuous pipeline shown in one drawing file. (Plan & profile digital files will not be accepted).
6. Verification that digital files do not contain unresolved line types, font files, and external references.
If the engineer does not have the capability to submit such files, the Department’s staff shall create the graphics file and recover the cost through plan check fees. The cost shall be determined by calculating 2% of the total bondable costs calculated for water and sewer facilities.
