Standard Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures, Pipes and Laterals

SCOPE
1.1 This specification covers the minimum performance and material requirements for resilient connectors used for connections between reinforced concrete manholes conforming to Specification C 478 and pipes, between wastewater structures and pipes, and between precast reinforced concrete pipe and laterals.
1.1.1 These connectors are designed to minimize leakage between the pipe and manhole, and between the pipe and lateral.
1.2 A complete metric companion to Specification C 923 has been developed-C 923M; therefore, no metric equivalents are presented in this specification.
Note 1—This specification covers the design, material, and performance of the resilient connection only. Connections covered by this specification are adequate for hydrostatic pressures up to 13 psi (30 ft) without leakage when tested in accordance with Section . Infiltration or exfiltration quantities for an installed system are dependent upon many factors other than the connections between manhole structures and pipe, and allowable quantities must be covered by other specifications and suitable testing of the installed pipeline and system.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific precaution statement, see 7.2.5.

Standard Specification for Performance Based Manufacture of Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe

ABSTRACT
This specification covers performance-based manufacture and corresponding test methods for reinforced concrete pipe to be used in the conveyance of sewage, industrial wastes, and storm water, and in the construction of culverts. Pipe furnished under this specification shall be designated as Class I, II, III, IV, or V. The reinforced concrete shall consist of cementitious materials; mineral aggregates; admixtures, if used; fibers; and water in which steel has been embedded in such a manner that the steel and concrete act together. Cementitious materials include cement, slag cement, fly ash, and allowable combinations of cementitious materials.
This specification also covers the basis of acceptance (age for acceptance and acceptance on the basis of proof of design tests, plant load-bearing tests, material tests, and inspection of manufactured pipe for visual defects and imperfections), pipe performance, joints, pipe proof of design testing (load bearing test, sample testing of pipe strength), physical requirements, repairs, inspection, and marking.
SCOPE
1.1 This performance based specification covers reinforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts.  
1.2 It is not the intention of this standard to dictate the material quantities and properties required for a pipe to conform to this standard except those in Section 6. Specific product formulations shall be considered proprietary and allowed to remain confidential to the manufacturer.
Note 1: This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that installation conforms to the construction specifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipe specified and provide inspection at the construction site.
Note 2: Attention is called to the specification for Reinforced Concrete D-load Culvert, Storm Drain, and Sewer Pipe (Specification C655). The distinction between this specification and C655 is in the D-Load specified and the practice for sampling pipe for conformance to the specification. This specification relies on standard classes of pipe (Class I-V), and sampling in accordance with Section 11.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C1618-19(Test Method)
Standard Test Method for Concrete Sanitary Sewer Pipe by Negative (Vacuum) Air Pressure

SIGNIFICANCE AND USE
5.1 This is a quality control test performed at the manufacturing plant to establish that the finished, shippable pipe meets the leakage limits stated in the specifications.
SCOPE
1.1 This test method covers procedures for testing of precast concrete pipe sections, prior to delivery, where maximum field leakage rates are specified.  
1.2 Tests described in this standard are intended to be used at the point of manufacture of the concrete pipe and are not intended for testing installed pipe (for field tests see Practices C969 and C1214). The user of this specification is advised that individual or multiple pipe sections may be tested for the purpose of testing the pipe barrel and additionally the joints in straight alignment when multiple pipe sections are tested.  
1.3 Test times are based on leakage rates and therefore are proportional only to the pipe diameter and are constant for any length of test pipe or pipeline.  
1.4 Test times tabulated and the rate of air loss in this standard are based on successful testing of installed pipelines. However, since air and water have different physical properties, retests of some pipelines not meeting field air tests have been successful when tested with water. The leakage rates of 0.0017 CFM/ft2 and 0.0003 CFM/ft2, were determined empirically as the maximums for pipe to meet the 50 and 200 gal/(in. of internal diameter) (mile of sewer) (24h) test rates, respectively.  
1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
Note 1: The availability of this test procedure for concrete pipe varies from location to location. Check with local supplier(s) for availability and recommendations.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See Section 6 for specific safety precautions.

Standard Practice for Prioritizing Sewer Pipe Cleaning Operations by Using Transmissive Acoustic Inspection

SIGNIFICANCE AND USE
4.1 Significance:  
4.1.1 Collection system maintenance requires allocating cleaning resources to the right place prior to system failure (sanitary sewer overflows, mainline blockages, and building backups). Transmissive acoustic inspection provides a tool to assist in allocating cleaning resources by prioritizing pipe segments based on their blockage assessment and thereby facilitating efficient cleaning resource allocation.  
4.1.2 This standard practice provides minimum requirements and suggested practices regarding the transmissive acoustic inspection of gravity-fed sewer line blockage assessment to meet the needs of maintenance personnel, engineers, contractors, authorities, regulatory agencies, and financing institutions.  
4.2 Limitations and Appropriate Uses:  
4.2.1 The blockage assessment provided by the transmissive acoustic inspection may not resolve the type of blockage(s) within the pipe segment nor resolve the location(s) of the blockage(s) within the pipe segment.  
4.2.2 Due to the physics associated with transmissive acoustic inspection, the blockage assessment may be confounded due to:
(1) Structural designs resulting in poor acoustic coupling,
(2) Pipe segments completely filled with water, for example, full pipe sag or inverted siphon, and
(3) Transient conditions within the pipe, for example, active lateral discharge or temporary flow surcharges.
These issues are addressed as part of the performance criteria specified in X1.5.  
4.2.3 Due to physics associated with acoustics and trade-offs in equipment design for conducting transmissive acoustic inspection, there are limitations based on the following pipe segment attributes:
(1) Pipe diameter,
(2) Pipe segment length,
(3) MH depth, and
(4) Flow levels.
Inspections conducted outside the manufacturer’s recommended ranges for these pipe segment attributes may result in the transmissive acoustic blockage assessment deviating from the performance criteria specified in X1.5...
SCOPE
1.1 This practice covers procedures for assessing the blockage within gravity-fed sewer pipes using transmissive acoustics for the purpose of prioritizing sewer pipe cleaning operations.2 The assessment is based on an acoustic receiver measuring the acoustic plane wave transmitted through the pipe segment under test in order to evaluate the blockage condition of an entire segment and to provide an onsite assessment of the blockage within the pipe segment. (1, 2, 3, 4, 5)3  
1.2 The scope of this practice covers the use of the transmissive acoustic inspection as a screening tool. The blockage assessment provided by the acoustic inspection should be used to identify and prioritize pipe segments requiring further maintenance action such as cleaning or visual inspection, or both. Thereby, also identifying the pipe segments which are sufficiently clean and do not require additional maintenance action.  
1.3 This standard practice does not address structural issues with the pipe wall.  
1.4 The inspection process requires access to the manhole (MH) from ground level. It does not require physical access to the sewer line by either the equipment or the operator.  
1.5 This standard practice applies to all types of pipe material.  
1.6 The inspection process requires access to sewers and operations along roadways or other locations that are safety hazards. This standard does not describe the hazards likely to be encountered or the safety procedures that must be carried out when operating in these hazardous environments.  
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate s...

Standard Practice for Installing a Protective Cementitious Liner System in Sanitary Sewer Manholes

ABSTRACT
This practice describes the procedures involved in the structural reinforcement, sealing, protection, and rehabilitation of sanitary sewer manholes by the application of a prepackaged protective cementitious liner system to all cleaned interior surface from the bottom of the frame to the bench. The manholes to which the cementitious liner shall be applied may be made of brick, concrete, block, and various other materials. Detailed descriptions are given for all prepackaged materials necessary for this practice that include materials for substrate repairs, cementitious repair materials, infiltration water control materials, cementitious water control materials, chemical grout materials, and lining materials. Detailed descriptions are also provided for each procedure involved here which includes surface preparation, high pressure cleaning, surface repair, mixing of prepackaged cementitious repair materials, spray application of the cement liner by manual surface sealing or centrifugal cast process, and curing of the freshly applied cementitious mortar.
SCOPE
1.1 This specification describes all the work required to structurally reinforce, seal, and protect sanitary sewer manholes. Applications include applying a prepackaged cementitious liner that can function as a full depth restoration or a partial depth repair. A uniform high-strength, fiber-reinforced cementitious mortar should be manually sprayed and hand troweled or centrifugally cast in a uniform, prescribed thickness to all cleaned, interior surfaces from the bottom of the frame to the bench. The cementitious liner may be applied to manholes constructed of brick, concrete, block, and various other materials.  
1.2 A manufacturer’s approved applicator shall furnish the complete application of the protective, prepackaged cementitious liner material. All of the cleaning, preparation, and application procedures shall be in accordance with the manufacturer’s recommendations.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Manholes are permit required confined spaces in accordance with OSHA definition and should be treated as such, requiring confined space entry permits, appropriate monitoring equipment, and the associated personal protective equipment.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
