The Mooresville Town Board had previously approved the above -referenced project and agreed to
provide potable water service to and accept the sewer flow from the proposed commercial
project. The Town of Mooresvilie's Water System Management Plan submitted approximately July
80, 2000, was approved and assigned WSMP No. 00-01958. Mooresvilie's Water Filter Plant PWS
. ID# is 01-49-015. Both water and sewer systems are owned and maintained by the Town of
Mooresville. Wastewater will be treated by the Town of Mooresvilie's Rocky River WWTP, NPDE$
Permit No. NC0046728. This project's expected input into the WW1P is 525 gpd.
It is your responsibility, as the engineer of record, to certify to the State that construction has been
completed in accordance with the approved plans and specs. The Town will conduct periodic
inspections during construction and will hold a final inspection prior to accepting the waterlines and
sanitary sewer system Into the Town's system. Two reproducible (mylar) copies of the "As-BuiIY'
drawings, on CD (compact disc) format, along with your engineer's certification are required to be
submitted to this office prior to acceptance by the Town Of Mooresville.

Sanitary Sewer Design Standards
Design Basis
All projects which use these guidelines shall be designed in accordance with and shall meet all
requirements of North Carolina Administrative Code (NCAC). It is the responsibility of the
Engineer of Record to ensure that all requirements are met. In cases where a statement herein
conflicts with such requirements, the more restrictive shall apply. Variations or exceptions to the
following guidelines must be approved by Town of Mooresville Director of Engineering.
2. Sewer design must be consistent with the Town's current Water and Sewer Master Plan and
overall needs of the sewer basin, following the natural drainage pattern of the basin. All sub
basins and any other basins or sub basins that may or will be pumping into the sewer being
designed must be identified. The Engineer of Record shall f-unish topographic maps, zoning
maps, and design data to substantiate sizing of all major basin outfalls. Installation depths shall
be minimized during the design process.
3. Forced sewer is corrosive and often produces excessive odors. Force main connections must be
considered in the design of the type of sewer pipe and location of connection.
4. Sewer mains must be extended on outfalls, in streets, or other easements to the property line or
as required by the Director of Engineering. The sewer design shall ensure future service is
available to the remainder of the drainage basin and or adjacent properties.
5. Sewer design is to result in a Iong lasting facility, where low maintenance and ease of
maintenance is the objective.
6. Average daily flow for residential units shall be established as 120 gallons per day per bedroom
with each residential unit having a minimum of two bedrooms. Single family residential usually
consists of three (3) bedrooms, while multi -family and attached housing usually consists of two
(2) bedrooms.
7. Open cut construction on existing paved roads shall be avoided. Existing paved roads shall be
bored or tunneled as appropriate.
Sewer Mains and Services
1. Gravity sewer sizes shall remain constant between manholes. In manholes with smaller upstream
sewer line and Larger downstream line, the crowns of the two sewer lines shall match. All sewers
shall have a straight alignment between manholes. Sewers shall be designed with uniform slope
between manholes.
2. Minimum diameter pipe for gravity sanitary sewer applications shall be 8 inches, with a
minimum of 4 inches for sanitary service laterals. Velocity calculations for determining pipe
diameter shall be based on Manning's formula, minimum velocity of 2 ft/sec with an "n" value
of 0.014.

3. Sewer depths greater than 12' for all sewer lines must have a letter requesting a variation
submitted with necessary documentation showing all alternatives, substantiating the depth of the
sewer required to serve the project, basin, or adjacent property. The variation must be approved
by the Director of Engineering.
4. Sewer depths for all sewer lines along road right-of-ways must consider future road widening.
Projections of future road grades may require increased depths or additional easements.
5. Four inch laterals may connect to the main line via a tee, wye, or tee/wye, per Detail S-15.0 and
S-16.0, or directly to the manhole, per Detail S-14.0A.
6.. Tapping saddle connections are not allowed in new sewer design/construction.
7. Laterals 6" or larger must connect to manholes per Detail S-14.0A.
8. Rubber couplings or "No -hub bands" are not allowed on sewer Iaterals or sewer lines.
Mechanical joint sleeves or approved equal must be used on pipe material transitions. However,
transitions from Vitrified Clay Pipe must use a rubber coupling (repair clamp). Approved
couplings must have a wide solid stainless steel center band .012" thick, with 4 stainless steel
screw clamps. Approved couplings are provided in the Materials Section of this Manual.
9. Sewer laterals less than 3 feet or over 12 feet deep must be ductile iron pipe. Sewer laterals
located in the right-of-way, or as directed by the Director of Engineering, will also be ductile
iron pipe. Otherwise Schedule 40 PVC pipe can be used for sewer laterals.

12. Deflection Testing of PVC Pipe: Not less than 30 days following completion of backfilI, PVC
pipe shall be tested for deflection with a 5% mandrel sized as defined in ASTM D-3034.
Mandrels shall be furnished by the Town of Mooresville. The mandrel shall be pulled through
each section of pipe from manhole to manhole. The mandrel must slide freely through the pipe
with only a nominal hand force applied. No mechanical device shall be used in pulling the
mandrel. Any pipe which refuses the mandrel shall be removed and replaced or re -rounded and
the bedding shall be properly constructed as specified to prevent excessive deflection. Such
sections shall be re -tested for deflection after completion of backfill.
13. Where design velocities are projected to be greater than 15.feet per second, the sewers and
manholes shall be protected against displacement by erosion and impact. Design velocities
greater than 15 feet per second must have a letter submitted with necessary documentation
showing all alternatives, substantiating the design, and must be approved by the Director of
Engineering. Ductile iron pipe (DIP) material is required when design velocities are 15 feet per
second or greater.
14. Pipes designed at minimum slopes should be avoided. Minimum slopes are difficult to maintain
during installation, and limits the ability to make necessary field changes. Minimum slopes
should only be used in outfalls and areas where it is necessary based on surface topography. Pipe
designed to be constructed at minimum slopes must have a letter submitted with necessary
documentation showing all alternatives, substantiating the design, and must be approved by the
Director of Engineering. Minimum slope is 1 percent, for dead-end lines or where low flows are
expected: Otherwise, minimum slopes must conform to the following Table:
