PART 6 EXECUTION
6.01. EXAMINATION
A. Section 01 30 00 - Administrative Requirements: Verification of existing conditions before starting work.
B. Verify trench cut is ready to receive work and excavations, dimensions, and elevations are as indicated on drawings.
6.02. PREPARATION
A. Correct over excavation with fine aggregate.
B. Remove large stones or other hard matter which could damage pipe or impede consistent backfilling or compaction.
C. Prior to the installation of each new individual sewer wye on the main, the Contractor shall determine the exact location of the existing sewer lateral at the back of sidewalk or PUE. Two acceptable methods of locating a sewer lateral at the back of sidewalk are.
1. Removing sidewalk and/or potholing by hand digging at the back of sidewalk to locate the existing lateral pipe a minimum of 24 hours prior to sewer main installation in that area.

2. Inserting a metallic electricians “fish tape” into the existing lateral pipe after the pipe is exposed during sewer main excavation and tracing the “fish tape” to the back of sidewalk using a pipe and cable metal locator. If this method does not locate the existing sewer lateral, method “1” shall be used.
D. All existing pipe impeding the construction of new laterals shall be removed per specification Section 02 41 10 and 02 01 10.
6.03. BEDDING
A. Excavate pipe trench in accordance with Section 31 23 00.
B. Place bedding material at trench bottom, level materials in continuous layer not exceeding 6 inches.
C. Maintain optimum moisture content of bedding material to attain required compaction density.
6.04. INSTALLATION - PIPE
A. Install pipe, fittings, and accessories in accordance with City of Sebastopol Standard Details and City of Santa Rosa Sewer Construction Specifications (Section 130). Seal joints watertight.
B. Lay pipe to slope gradients noted on drawings to meet join existing property side laterals; with maximum variation from indicated slope of 1/8 inch in 10 feet. Pipe shall be installed at continuous slope as shown on drawings.
C. Excavate bell holes to permit proper joint installation.
D. Install pipe to have bearing along entire length of pipe.
E. Install bedding at sides and over top of pipe to minimum compacted thickness of 6 inches.
F. Cover is the distance from the top of the pipe to the final finished grade measured directly over the pipe.
G. Minimum cover for all sewer mains and laterals shall be 36”. The Engineer may approve shallower installations but in no case shall cover be less than 24”.
H. Where cover is less than 36”, special construction techniques must be approved such as the use of ductile iron pipe, a concrete cap over the trench, or the use of control density backfill.
I. Refer to Section 31 23 00 for backfilling and compacting requirements. Do not displace or damage pipe when compacting.
J. Install all sewer laterals perpendicular to the curb unless otherwise shown per plan.
1. Any lateral not installed perpendicular to the curb shall installer tracer wire (material & type per Section 33 11 00) in the following manner, unless otherwise shown on drawings and details:
a. Wrap wire two times around wye connection at main and secure. b. Lay both ends on top of and along the lateral to the cleanout and up the cleanout riser. Both ends of the wire shall extend approximately 6 inches beyond riser.
c. Secure wire to top of lateral pipe at approximately 5 foot intervals. Ends of wire must be easily accessible inside the cleanout box.

K. Install plastic ribbon tape continuous over top of pipe buried 12 inches below finish grade, above pipe line; coordinate with Section 31 23 00.
6.05. TESTING OF SEWERS
A. Test for leakage shall be performed for all portions of the sewer, including manholes, is required.
1. All testing required shall conform with the City of Santa Rosa Sewer Construction Specification 130-1.08
B. All new or rehabilitated sanitary sewer manholes shall be tested unless otherwise directed by the Engineer. If the manhole fails the test, the manhole shall be repaired and retested at the contractor’s expense. If manhole joint sealants are compromised during the vacuum test, the manhole must be disassembled and the joint sealants replaced. If there is reason to believe that the manhole has been disturbed after the initial vacuum test, additional tests may be requested by the Engineer and performed at the Contractor’s expense.
1. Leakage Testing:
a. Water Test: Manholes, after inlets and outlets have been plugged, shall be filled with water to the rim of the frame casting and shall lose no more than 2 inches over a period of 30 minutes.
b. Vacuum Testing shall be performed in accordance with ASTM C 1244-20.
Vacuum testing shall not take place until all permanent paving is complete. 1) All lift holes and joints shall be grouted and the entire manhole, including grade rings, sealed prior to testing.
2) All pipes entering the manhole shall be temporarily plugged, taking care to securely brace the pipes and plugs to prevent them from being drawn into the manhole.
3) The test head shall be placed in accordance with the manufacturer’s recommendations. The test unit shall be braced against the manhole frame and not the grade ring(s) or taper.
4) Vacuum test gauge and test equipment used for this test shall be supplied by the Contractor and shall be operated per manufacturer’s specifications by qualified personnel. Accuracy and calibration of the guage shall be certified by a reliable testing firm at 6 month intervals, or when requested by the Engineer.
5) A vacuum of 10 inches HG (4.91 PSI) of mercury shall be drawn on the manhole, the valve on the vacuum line of the test head closed, and the vacuum pump shut off. The time it takes the indicator gauge to drop from 10 inches HG (4.91) to 9 inches Hg (4.4 PSI) shall be measured. The manhole will pass the vacuum test if the time is greater than shown in the following table:
6) After the vacuum test, manholes shall be visually inspected for leaks and defects and repaired as required by the engineer
c. Exfiltration or Infiltration testing

2. Installation of vacuum equipment and indicating devices must be in accordance with the manufacturer’s recommendations and performance specifications, which must be provided by the manufacturer and approved by the Engineer. The equipment must be capable of testing the entire manhole, including cast iron frame and grade adjustment rings.
6.06. BYPASS PUMPING AND/OR DIVERSION SYSTEM
A. Bypass pumping shall be performed per the City of Santa Rosa Sewer Specification 130-1.10 B. Contractor shall allow up to 10 working days for response from the City and Engineer for any request regarding sewer flows.
6.07. FIELD QUALITY CONTROL
A. Section 01 40 00 - Quality Requirements: Field inspecting, testing, adjusting, and balancing.
B. Compaction Requirements: In accordance with Section 31 23 00.
C. When tests indicate Work does not meet specified requirements, remove work, replace and retest.
6.08. PROTECTION OF FINISHED WORK
