Effective immediately, the following will be accomplished by all contractors before starting any work or excavationaround or on any sewer line owned by the North Davis Sewer District

Hours of OperationThe District's working hours are 7:00 a.m. to 3:30 p.m., Monday through Friday. No sewer inspection willbe done on weekends, holidays or after 3:00 p.m.All inspections lasting after 3:30 p.m. will result in overtime being billed to the contractor.Multiple inspection visits required for work that is incomplete, not to District standards, or not ready for inspection will result in additional time being billed to the Contractor.

Sewer Lateral Connections:No work shall begin until the proper fees of $240.00 for connection and inspection, plus impact fees as calculated by the City or District (whichever may apply) are certified to the District as having been paid. The District only accepts cash or check.No work shall begin until the proper building permits and licenses have been obtained from the City, County, or Sewer District.Minimum notice of 48 hours shall be given to the District prior to any work commencing on or digging being done on District-owned lines.No digging or work shall be done on District-owned lines without the presence of a District Inspector.All sewer taps must be Core Drilled, INSERTA TEE, GPK PRODUCTS, INC, or equivalent. The Contractormust accurately size and procure sewer taps based on the existing District's sewer (material anddiameter) and the sewer lateral (material and diameter) to be connected.

Setting of Manholes on District-Owned LineManholes are required to be set for connecting lines 6 inches or larger.No manholes shall be set on District-owned lines without prior approval by the District. Contractors shallsubmit design drawings and manhole details of proposed manholes on District line for approval 14 daysprior to work commencing. Design drawings shall be submitted in PDF electronic format unless otherwiserequested by the District.After approval of drawings, a minimum of 48 hours notice shall be given to the District inspectors beforeany manhole is set on a District-owned line. The manhole must be set in the presence of a District inspector.

Flow Control and Bypass Pumping OperationsThe Contractor is solely responsible for bypass control and maintaining sanitary sewer flows within the sewer system during the Work in accordance with Utah State Code R317-801. Service shall be maintainedat all times throughout the duration of the project. The Contractor shall provide proof of flow calculationsproving adequacy of the system and the selected equipment if the District chooses to review.

Concrete BatchingReady mix concrete shall be provided in accordance with ASTM C94, Standard Specification for Ready-Mixed Concrete.The design water content of the mix (w/c ratio) shall not be exceeded. Addition of water, air entrainment orsuperplasticizer shall only be performed by the Supplier.Non-air entrained concrete shall be discharged ninety (90) minutes after batching. Air entrained concreteor concrete that includes silica fume shall be discharged within sixty (60) minutes of batching.Requests for longer batching times shall be submitted and accepted by the District prior to procurement ofconcrete by the Contractor.The District shall not be responsible for the cost of rejected batches exceeding time limitations, loss of air-entrainment or slump.

Warranty:Contractor shall guarantee work for a period of one year from the date of installation.

Failure of Contractors to comply with these guidelines could result in the Contractor being barred from working onDistrict lines. If there are any questions on a line being a District line, please contact the District office at801-825-0712.

Revision 3, Adopted 4/23/2019

STANDARD MANHOLE ON EXISTING SEWER LINE

1. Manhole shall be constructed so as to prevent load to the existing pipe. The base of the manhole shallprovide a minimum of 9 inches of concrete beneath the existing pipe unless otherwise shown, placed on 12inches of one inch gravel bedding compacted to 95% density.

2. Manhole floor elevation shall be a minimum of 2 inches above top of pipe, have a 12:1 slope to the pipe, anda smooth finish.

3. Connection to manhole shall be made using a flexible, double banded, watertight connection per ASTMC923 and ASTM C1173. The flexible seals shall not exceed 50% of the manufacturer's recommendationsfor axial deflection for the installed condition. Acceptable products include Kor-n-seal, Fernco, MissionRubber Company, or approved equal. All hardware shall be 316 series stainless steel, unless otherwiseapproved.

4. Manhole shall be constructed using a pre-cast eccentric type sections and cast iron traffic type frame andcover marked "NORTH DAVIS SEWER". Section joints shall be sealed with rubber gaskets and shall bewatertight.

5. Wrap exterior joints. Wrap shall conform to ASTM C877 Type II or Type III. Press-seal Ez-Wrap, CretexWrap, Conseal 2/2 or approved equal.

6. Invert of branch line at manhole connection shall be adjusted to be at or near crown of existing main line.

7. Branch line channel to be formed with same slope, size, depth, and shape as pipe with smooth finish; it shallbe curved in direction of flow with uniform radius and minimize dropping and splashing of flow.

8. Cutting into existing line shall be made by smooth saw cuts.

9. Installing Contractor shall be responsible for proper slope and installation of connecting line.

10. Installing Contractor shall be responsible for proper backfilling, compacting, and pavement restoration.

11. Contractor shall notify District 48 hours before installation begins and a District inspector must be presentbefore installation takes place.

12. The Contractor shall test each manhole with either a Low Pressure Air Test, a Vacuum Test, an ExfiltrationTest, or with an Infiltration Test according to the given soil and groundwater conditions of the site. The LowPressure Test and Vacuum Test shall be performed per ASTM F1417 and ASTM C1244 accordingly. TheInfiltration and Exfiltration Tests shall be performed per ASTM C969. If the groundwater is less than 2 feetabove the crown of the pipe, perform the exfiltration test. If the groundwater is greater than 2 feet above thecrown of the pipe, perform the infiltration test.

13. Contractor shall meet all restoration requirements of the Agency, City or UDOT where the manhole isinstalled and shall coordinate any additional installation or inspection requirements with the Agency.

CONNECTION TO AN EXISTING MANHOLE

14. Item numbers 3, 5, 8, 9, 10 and 11 above shall apply.

15. In addition, the manhole junction channel shall be constructed to the same size, shape, and slope of theincoming line. Channel shall curve in the direction of flow with uniform radius and minimize dropping andsplashing of flow.

16. No manhole connection shall be made until complete design drawings of the manhole and line installationsare submitted to the District for approval - 14 days prior to work commencing.

NOTE

1. District reserves the right to require precast FRP or polymer manholes on pipes that are planned to berehabilitated by cured-in-place (CIPP) or other methods within two years of drawing submittal.

MANHOLE DIAMETER

Minimum manholes diameters where District pipes diameters are greater than 48-inch, where greater than three(3) inlets are present, where more than one outlet is provided, where trough patterns require angles less than 90degrees, or where inlet pipe and outlet pipe elevations are separated by one-foot or more shall be reviewed andaccepted on a case-by-case basis by the District. The District shall be contacted as soon as possible in thedesign process to determine any additional requirements for manholes.

Minimum internal diameter for FRP tee base manholes to be installed on FRP mainlines shall be reviewed andapproved by the District on a case-by-case basis.

Minimum internal manhole diameter shall be selected based on the following criteria:

ND-03 Manhole Diameter Requirements 1 of 2


For alternative configurations, manhole sizing recommendations may be provided by the precast fabricator. Theminimum structural support between openings is 6 inches. Recommendations must be supported by designmethods (drawings, calculations) provided by the precast manufacturer in accordance with applicable industrystandards such as NPCA.
