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 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. 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 3 meters.
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
[state or local agency having jurisdiction] [Insert the installation standards].
4-9.6
Cover. Sewer lines shall be located at a depth greater than the frost penetration.
Coordinate with building connection requirements. To prevent the pipe from being crushed by
construction vehicles and the design vehicle, the minimum cover above the top of pipes shall be
750mm unless pipe materials are used and/or unless the pipe is concrete encased with a minimum
SOW-50
