and submerged ferrous metallic structures not covered above; Ferrous metallic piping passing
through concrete shall not be in contact with the concrete.
4-8.9
Field Quality Control for Water Distribution. The [contracting officer] [Insert the
appropriate person] will conduct field inspections and witness field tests specified. The contractor
shall perform field tests, and provide labor, equipment, and incidentals required for testing, [except
that water needed for field tests will be furnished as set forth in [Insert appropriate document]].
[Water needed for field tests will not be furnished by the government]. Do not begin testing on any
section of a pipeline where concrete thrust blocks have been provided until at least 5 days after
placing of the concrete. Testing procedures and requirements shall comply with the [requirements
of the agency having jurisdiction.] [Insert the installation testing standards].
4-9
SANITARY SEWERAGE SYSTEM. The design of the sanitary sewer distribution
system shall be in accordance with the [Insert State or local agency having jurisdiction.] Where the
requirements of the agency having jurisdiction and the requirements defined herein disagree, the
more stringent shall apply. The contractor shall determine the sewerage contribution for the
facilities and shall verify the design of all components of the sanitary sewer system.
4-9.1
Analysis of Existing System Capacity. [The contractor shall provide design
calculations that show the existing system is capable of handling the additional flows.] [The
Installation shall state that the existing system is capable of handling the additional flows.]
4-9.2
Calculate Sewage Contribution. Calculate the sewage contribution from the new
facilities in accordance with the [Insert State or local agency having jurisdiction.] [Insert installation
standards for sewage contribution].
4-9.3
Connections to Sewage Collection Mains and Building Service Lines. [The
installation shall insert specific connection location requirements.] [The contractor shall be
responsible for the design of the sizes, locations, and means of connections to the existing system
based on Facility requirements and system conditions. Establish the location for the connection
based upon economics and site design parameters.] Connect to gravity mains with a manhole.
4-9.3.1
Building Sewer Laterals and Connections. Laterals and building connections shall be
designed and constructed in accordance with the International Building Code [2000 or latest
edition]. Minimum diameter for laterals shall be 150 mm [6 in] while maintaining a minimum velocity
of 45 meters per minute [2.5 fps].
4-9.3.2
Main Collection Trunks. Pipe sizes and slopes shall be calculated using the Manning
Formula. Manholes are required at all changes of direction and spaced not more than 122 m [400
ft] apart [or as required by installation]. Curved sewers are prohibited. Pipes shall be designed to
flow full and maintain a minimum velocity of 45 meters per minute [2.5 fps]. If siphons are used, two
lines of equivalent capacity shall be used with clean-outs.
4-9.4
Trenches. Sewer and water lines, mains or laterals, shall be placed in separate
trenches. The separate trenches shall maintain a minimum lateral separation of 3m [10 ft].
4-9.5
Minimum Sewer and Water Distribution Pipe Separation Requirements. Parallel
water and sewer pipe and crossings between water and sewer pipe shall be in accordance with the
SOW-90
